Nubway's PS400 is a trolley-mounted picosecond laser designed around tattoo and pigment work, and the model code does not appear in any output specification Nubway currently publishes. A PS400 brochure exists but was not publicly readable. Every laser parameter on this page is therefore attributed to Nubway's published picosecond platform literature, which lists a 450 ps pulse, 1064 nm and 532 nm as standard wavelengths with 585, 650 and 755 nm offered as options, up to 1500 mJ at 1064 nm and 800 mJ at 532 nm, a 1 to 10 Hz repetition rate, a 2 to 10 mm zoom spot and a top-hat beam profile. None of those figures is confirmed for this unit.

The photograph does establish the working layout. An articulated delivery arm rises from the top of the console and carries the handpiece, and an angled touchscreen sits at standing height beside it. That arrangement lets one operator reach the face, back or forearm without dragging the trolley around the couch, and it keeps the handpiece off the treatment surface between passes.

The console is finished in white with black side panels and ventilation grilles, and it stands on four castors. A circular fitting sits on the front panel. Nubway's platform literature describes a seven-joint arm sourced from South Korea, a red 655 nm aiming beam and four operating modes, all unconfirmed for this model.

Size, shipped mass and electrical rating are not published. The device falls under laser safety law, and the Class 4 classification typical of this category requires a Laser Protection Adviser, written local rules, and matched protective eyewear. Medigear.uk can arrange delivery and familiarisation. Request the PS400 datasheet, laser classification, declaration of conformity and eyewear specification from the seller before ordering.

Tattoo removal is the work this platform is built for in Nubway's literature, and most demand comes from black or blue ink that a client regrets, has outgrown, or needs cleared for a cover-up. A clinic taking on that work needs a room it can control for every appointment, a consultation that sets expectations over months, and a photographic record of each area. Research on picosecond tattoo treatment points to several sessions spaced weeks apart, and a course planned that way from the start is easier to explain and fit into a clinic diary.

Pigment work is the second stream. Nubway lists freckles, sun spots, age spots and melasma, and a randomised trial of 60 melasma patients comparing picosecond 1064 nm treatment, picosecond 755 nm treatment and 2% hydroquinone cream found each group improved from baseline. Clinics should treat melasma as a condition that relapses and needs sun protection and topical care alongside any laser session, not as a single-visit correction. Acne scarring and skin texture appear in the same literature, usually linked to a fractional or array handpiece, so confirm whether one ships before advertising that service.

The unit suits dermatology and aesthetic clinics, cosmetic surgery practices that offer tattoo removal, and dedicated laser studios with a secured treatment room. It is less suited to a hair and beauty salon without a controlled area, because a Class 4 room brings duties that a shared space cannot meet. Clinics in Wales, Scotland and Northern Ireland must complete the registration their regulator requires before the first client, and English clinics should check local licensing. The conformity documentation those registrations require is issued by the manufacturer and provided by the seller.

A layout that keeps the operator at the couch

The articulated arm carries the handpiece from the top of the console, so the operator moves around the client while the trolley stays put. Long sessions on a back or a full sleeve involve many repositionings, and an arm that follows the hand reduces the stops needed to shift equipment.

One console on castors

The laser head, control screen, and delivery arm share a single wheeled chassis. The unit can move between two rooms on the same floor, although every room it enters needs its own controlled-area arrangements and local rules.

Settings chosen on a large angled screen

The photograph shows a sizeable touchscreen angled towards a standing operator. Nubway's platform literature describes four operating modes selected on screen. A clear display matters when wavelength and spot size change several times within one appointment.

A family specification worth asking about

Nubway publishes a detailed picosecond specification for its platform, giving buyers a concrete list to share with the seller. Asking which of those figures apply to the PS400 turns a vague brochure conversation into a set of written answers.

Pigment and tattoo work from one room

The family literature covers both tattoo ink and benign pigment on the same platform. For a clinic building a service menu, that can mean one controlled room and one set of local rules serving two treatment streams, as long as the confirmed wavelengths support both.

A mains-powered unit with known obligations

The duties around a Class 4 aesthetic laser are well mapped in the UK: an adviser, local rules, eyewear, training and nation-level registration where it applies. Buyers can plan every one of those before delivery, and none depends on unpublished details about the machine.

An honest basis for consultation

Because the published evidence shows black and blue ink clearing over several sessions, clinics can set realistic expectations from the first visit. Clients told plainly about session numbers are less likely to feel misled halfway through a course.

Delivery arranged through one enquiry

Medigear.uk can arrange delivery, installation, commissioning, familiarisation and service cover with the seller. That brings the practical steps after purchase into one conversation for business buyers worldwide.

Picosecond pulse regime

The unit is marketed as a picosecond laser, and Nubway's platform literature quotes a 450 ps pulse. Pulses this short fragment pigment mainly through a photomechanical effect. Ask for a measured pulse-width report for the PS400 itself.

Standard wavelengths in the family literature

Nubway lists 1064 nm and 532 nm as standard on its picosecond platform. In tattoo work, 1064 nm is generally used for dark ink and 532 nm for red and warm tones. Confirm both for this unit.

Optional wavelengths in the family literature

The same literature offers 585, 650 and 755 nm handpieces as options. These are aimed at yellow, green and blue inks and at some pigment work. Treat them as extras unless the quotation lists them.

Pulse energy in the family literature

The platform is quoted at up to 1500 mJ at 1064 nm and 800 mJ at 532 nm. The energy at the aperture after the arm matters clinically, and it should be measured and recorded at commissioning.

Adjustable spot in the family literature

The family literature lists a zoom spot from 2 to 10 mm. Smaller spots raise fluence for fine work, while larger spots cover more skin per pulse and generally reach deeper. Confirm the mechanism for changing spot size on the PS400.

Repetition rate in the family literature

The platform is quoted at 1 to 10 Hz. Rate affects treatment speed over a large area, and higher rates at high energy make eyewear discipline and room control all the more important.

Top-hat beam profile in the literature

Nubway describes a top-hat profile, meaning energy is spread evenly across the spot. An even profile reduces hot spots within each pulse. Ask whether a beam profile measurement is supplied.

Articulated delivery arm

The photograph shows a jointed arm mounted on top of the console. Nubway's platform literature specifies a seven-joint arm from South Korea. Arms need periodic alignment checks, so ask who performs them and how often.

Touchscreen control

An angled colour touchscreen sits at the top front of the console. Screen size, software language options, and any stored presets are not published.

Aiming beam in the family literature

The platform uses a red 655 nm diode aiming beam. An aiming beam shows where the treatment pulse will land, which helps with precision on small tattoos and near the eyebrows.

Four operating modes in the family literature

Nubway's literature refers to four modes on its picosecond interface but doesn't detail each. Ask the seller to name them and explain what changes between them.

Wheeled chassis

Four castors carry the console. Check whether they lock, and whether the unit is stable on a slightly sloped floor at delivery.

Front-panel fitting

A circular fitting is visible on the front panel. Its function is not published. Confirm the emergency stop, key switch, and remote interlock arrangements, as local rules depend on them.

Laser classification

Picosecond aesthetic lasers of this output are typically Class 4 under BS EN 60825-1. The classification label on the unit and the declaration of conformity settle it for the PS400.

Electrical safety family

As a laser for cosmetic and therapeutic use, the relevant safety standards are IEC 60601-1, with the laser-specific IEC 60601-2-22, plus BS EN 60825-1 for classification. Which of these the manufacturer declares is set out in the conformity documentation.

The PS400 meets a clear need for clinics doing tattoo and pigment work: a mobile console with an articulated arm and touchscreen, built on a picosecond platform that Nubway documents in detail. What Nubway does not yet publish is a specification under this model code, and that gap is the first thing to close. Ask for the datasheet, a pulse-width report and the laser classification, and plan the room, the adviser and the eyewear around the confirmed wavelengths. Clinics that set honest expectations about session numbers will get the most from it. Medigear.uk lists the PS400 for business buyers worldwide and can arrange delivery, installation, commissioning, familiarisation and service cover. Request the datasheet, declaration of conformity, eyewear specification and warranty terms from the seller with the quotation.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

None under the PS400 code itself. Nubway's published picosecond product page lists a 450 ps pulse, 1064 nm and 532 nm as standard, optional 585, 650 and 755 nm handpieces, up to 1500 mJ at 1064 nm and 800 mJ at 532 nm, 1 to 10 Hz and a 2 to 10 mm spot. Treat those as the family figures, and ask the seller to confirm in writing which apply to this unit. A picosecond claim should be backed by a measured pulse-width report and energy at the aperture, and both are reasonable requests at quotation.

Nubway's picosecond literature names tattoo removal, freckles, sun spots, age spots, melasma and acne scarring as the intended work. The strongest published evidence for picosecond lasers concerns black and blue ink. A 2026 systematic review of 46 Nd: YAG tattoo studies found that black and blue pigment generally needed four to eight sessions to reach at least 75 per cent clearance, and that coloured inks and professional tattoos cleared less predictably. Plan consultations around those realistic numbers.

The published research does not support promising that to clients. The same 2026 review reported that picosecond Nd: YAG systems may reach similar clearance with fewer sessions or lower fluence, but it did not find consistent superiority over nanosecond Q-switched systems and called for better-designed trials. The honest message at consultation is several sessions spaced weeks apart, with progress photographed at each visit.

It suits a clinic ready to run a Class 4 laser room properly, with a Laser Protection Adviser, local rules, a controlled area and trained operators. It is a poor fit for a mobile service, a shared room that cannot be secured during treatment, or any buyer who needs a confirmed specification before committing. A service treating mainly deeper skin types should take specialist clinical advice on wavelength and settings first, because pigment change after laser treatment is more likely in melanin-rich skin. Where the seller cannot confirm the figures in writing, Medigear.uk can point the buyer to an alternative specification.

Laser safety falls under the Control of Artificial Optical Radiation at Work Regulations 2010 across Great Britain, and MHRA guidance on lasers in aesthetic practice sets out the expected safe system of work. Registration depends on the nation. Wales requires services using Class 3B or 4 lasers to register with Healthcare Inspectorate Wales, Scotland requires independent clinics using them to register with Healthcare Improvement Scotland, and Northern Ireland registers laser clinics through RQIA. England has no national registration for cosmetic laser work yet. However,h some local authorities run their own licensing, and a national licensing scheme under the Health and Care Act 2022 is being developed. Check the current position before opening, because this area is moving.

That depends on the intended purpose the manufacturer declares. Under UK MDR 2002, equipment used purely for cosmetic tattoo removal generally sits outside the medical device regime in Great Britain, while treating a skin condition can bring it inside. In the European Union, lasers intended for tattoo removal and other skin treatments fall under Annex XVI of Regulation (EU) 2017/745 even without a medical purpose. Ask the seller for the declaration of conformity, which names the legal manufacturer and the route used. Conformity requirements differ by destination market, and the seller confirms what applies where the unit is going.

Plan for protective eyewear rated to every wavelength the unit emits, for the operator, the client and anyone else in the room. The rating must match the confirmed wavelengths, so it cannot be finalised until the seller confirms which handpieces ship. Add a lockable room with a warning sign, window covering where beam paths allow, and written local rules. Whether eyewear is included in the standard configuration is not published, so ask at quotation.

The cooling arrangement, pump source and service intervals are not published for this model. If the design uses a flashlamp, lamp life is usually the main recurring upkeep, and some cooling systems need periodic water and filter changes. Allow for an annual Laser Protection Adviser review, electrical safety testing under your own policy and arm alignment checks. Medigear.uk can arrange service cover, spares and consumables through the seller.

The standard configuration is not published under the PS400 code. Ask the seller to list every handpiece supplied, whether any fractional or array lens is included, how many pairs of eyewear ship, and whether the key switch, footswitch and interlock connector are fitted. Never assume optional handpieces are included just because a photograph shows them.

Medigear.uk can arrange delivery, installation, commissioning and familiarisation with the seller. Clinical training on settings, skin assessment and complication management is a separate need and should come from a recognised laser course. The seller sets warranty terms, response times and spare-part lead times at quotation.
