Blackstone DGT-50Z

Product Code: STDI-SE-3913

Fifty litres of vacuum sterilising still counts as a small steriliser.

Fifty litres, a 665 mm-deep cylindrical chamber, and Class B vacuum cycles bring the DGT-50Z close to the 60-litre ceiling of EN 13060, while keeping it a small steriliser running on a 3.5 kW supply.

The DGT-50Z is Blackstone's 50-litre Class B benchtop steam steriliser for departments that want large batches while staying within the small-steriliser standard. Its chamber measures 320 mm wide and 665 mm long, holds about 53.5 litres by geometry, and draws 3.5 kW from either an AC 220 V 50 Hz or an AC 110 V 60 Hz supply. The series is designed for 139 °C and rated for 0.22 MPa and 134 °C, with sterilising set between 116 and 134 °C. Design pressure, sterilising time and drying time range from −0.1 MPa, 4 minutes and 0 minutes.

Its position under the small-steriliser threshold is the defining feature, because it decides which rules apply. With a geometric volume below 60 litres and a bore too narrow for a standard module, it falls within EN 13060, so the evidence to request is Class B type testing, not large-steriliser testing to EN 285. The duties around it do not shrink with the standard: a written scheme of examination, validation, daily tests, written operating instructions and records all still apply.

Series information places the HS-DGT-Z range in Class B. In the series photograph, a slim display panel and grip sit to the right of a broad door with a recessed pull, above adjustable feet, with vents along the side. The enquiry team provides maximum sterilising and drying times, the upper design pressure, the programme list, trays, water arrangements, and clearances.

Its cabinet stands 570 mm high on an 850 × 660 mm base and weighs 106 kg. Buyers can order it in more than 80 countries through Medigear.uk, and the enquiry team provides stock and lead time information.

Busy dental practices and dental hubs, hospital outpatient departments, day surgery units and clinics that want large batches from a benchtop Class B steriliser are the natural buyers for the DGT-50Z. Its vacuum cycles take pouched trays, cannulated and hollow instruments including handpieces, and textiles or other porous items.

Staying under the small-steriliser threshold keeps the standards position simple, but it does not reduce the duties of the department that runs the machine. A Scottish survey of dental practices showed how often those duties slip: only 51% of sterilisers had been tested when installed and 26% commissioned, and the documents reviewed rarely showed whether daily, weekly, quarterly or yearly tests had been done. Written operating instructions were missing in 61% of practices, while pressure vessel insurance covered 79% of surgeries with bowl-and-instrument sterilisers.

Those figures describe the paperwork a 50-litre benchtop steriliser requires. Before its first load, it needs commissioning and validation. From then on it needs a written scheme with periodic examinations, daily air removal tests and periodic testing, written instructions that staff can follow, and a logbook that links every load to its cycle.

Planned at purchase, those obligations become routine; left until an inspection, they become findings. Naming one person to own them from day one is the simplest safeguard.

Tender specifications, including NHS ones, set out compliance documentation alongside capacity for sterilisers of this kind, and buyers in other public systems follow suit. The conformity documentation those procurement routes require is issued by the manufacturer and shared by the enquiry team.

A Clear Place in the Standards

With a geometric volume below 60 litres and no room for a module, the DGT-50Z falls within EN 13060. Buyers know which type-test evidence to ask for from the outset.

Large Batches Under the Small-Steriliser Standard

A nominal 50 litres of chamber volume handles full tray sets while remaining a small steriliser. Departments gain capacity without moving into the large-steriliser category.

Stated Figures for Validation

The series rows give 139 °C design temperature, 0.22 MPa, and 134 °C rated working conditions, with a 116 to 134 °C sterilising window. Validation starts from published numbers.

Vacuum Built Into the Design Range

A design pressure range that opens at −0.1 MPa shows the vessel is rated for the vacuum stages of each cycle.

Supply Versions Stated

The series rows list AC 220 V 50 Hz and AC 110 V 60 Hz versions. UK departments can specify the right one at order.

Paperwork With a Clear Shape

Manual, written scheme, validation report, test results and logbook form a defined set. Inspectors and insurers find what they expect.

Class B Scope

Series information places the range in Class B, covering wrapped, porous and hollow loads in the same chamber.

A Readable Display

A slim display panel beside the door shows cycle progress, as the series photograph illustrates.

Traceable Loads

Labels on each load tie it to the cycle record. Traceability runs from the steriliser to the patient.

50-Litre Chamber

A 320 mm bore runs 665 mm deep, about 53.5 litres by geometry against a nominal 50 litres.

Class B Category

Series information puts the HS-DGT-Z range in Class B, the EN 13060 vacuum class.

The DGT-50Z suits dental hubs, larger dental practices, outpatient departments, day surgery units and clinics that want large Class B batches on a bench and can run the paperwork that comes with them. It is the wrong choice for departments without an owner for those duties, for rooms without a dedicated circuit, and for sites that cannot arrange mechanical handling or a suitable stand. Before ordering, name the person responsible for compliance, book commissioning and validation, and arrange the written scheme with a competent person, often the insurer's engineer. Medigear.uk lists the DGT-50Z for business buyers worldwide and can arrange delivery, installation, commissioning, familiarisation and service cover. Ask the enquiry team for the EN 13060 evidence, the manual, the time limits and the programme list before ordering.

FAQ

Frequently Asked Questions

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

EN 13060 is the standard for small steam sterilisers, which covers chambers up to 60 litres that cannot take a standard sterilisation module. The DGT-50Z holds about 53.5 litres by geometry, and its 320 mm bore is too narrow for a module, so it sits within that scope. Ask the manufacturer for Class B type-test evidence under EN 13060. EN 285, the large-steriliser standard, does not apply.

Installation checks, commissioning, and validation must be carried out and recorded by a competent person, in line with the decontamination guidance for the setting. These steps are easily skipped: a survey of Scottish dental practices found only 51% of sterilisers had been tested at installation and 26% commissioned.

As a pressure system, it needs a written scheme of examination under Great Britain's Pressure Systems Safety Regulations 2000, prepared by a competent person who also sets the examination intervals. In practice,e that person is often an engineer from the practice's insurer; the same survey found pressure vessel insurance in place at 79% of surgeries with bowl-and-instrument sterilisers.

The operating manual or written instructions, the written scheme and examination reports, the validation report, the daily and periodic test results, and a cycle logbook. Written instructions matter more than they seem: in the Scottish survey, 61% of practices had no written instructions for operating their steriliser.

Each day starts with an air removal test, using a helix or Bowie-Dick device, and an automatic control check. Weekly, quarterly and yearly tests follow under the decontamination guidance for the setting, such as HTM 01-05 for dental practice in England. The test programmes on the DGT-50Z appear in the programme list from the enquiry team.

From the series rows: 139 °C design temperature, 0.22 MPa rated working pressure, 134 °C rated working temperature and a sterilising window of 116 to 134 °C. Lower limits are −0.1 MPa for design pressure, 4 minutes for sterilising and 0 minutes for drying; the enquiry team supplies each upper limit with the programme list.

At 3. ,kW, the unit draws about 15 A from a 230 V supply, so a 13 A plug will not do and a dedicated circuit is needed, designed and installed by an electrician to BS 7671. Order the AC 220 V 50 Hz version for UK mains.

The unit weighs 106 kg and its crate 131 kg, well beyond safe team lifting, so delivery relies on lifting aids such as a pallet truck or lifting table, assessed under the Manual Handling Operations Regulations 1992 and LOLER. It needs a bench or stand that takes the 850 × 660 mm base and carries the unit, its water and a full load.

Wrapped and pouched instrument sets, hollow instruments such as handpieces, and porous items, all within the Class B scope. Trays are sized to the 320 mm bore, since a standard module does not fit, and the enquiry team lists those supplied.

Each load needs a reference that ties it to its cycle record, kept with the logbook an inspector will review. The enquiry team explains how the DGT-50Z records and outputs cycle data.

The DGT-50Z is typically Class IIa under UK MDR 2002, or higher depending on use, as stated on the manufacturer's declaration of conformity, which the enquiry team shares. Expect that declaration to name the legal manufacturer and to reference EN 13060, EN 61010-1 and EN 61010-2-040.
