The DGT-23Z from Blackstone is a 23-litre Class B benchtop steam steriliser built for multi-chair dental practices and minor surgery services that pouch their instruments. Its chamber is a cylinder 250 mm across and 450 mm deep, about 22.1 litres by calculation, and the unit is rated at 2.2 kW. Rows shared across the series on the Blackstone sheet give a design temperature of 139 °C, a rated working pressure of 0.22 MPa and a rated working temperature of 134 °C. Design pressure starts at −0.1 MPa, sterilising temperatures at 116 °C, sterilising times at 4 minutes and drying times at 0 minutes.

Chamber depth is the defining feature, and it decides who the machine is for. A practice with several chairs, oral surgery sets or long forceps needs room to lay pouched instruments flat, never folded, and to run handpieces through the same vacuum cycles. A practice that only reprocesses unwrapped solid instruments, or runs a handful of cycles a week, gains little from the extra depth.

Series information places the HS-DGT-Z range in Class B. In the Blackstone photograph, a wide door with a recessed pull takes up most of the front, with a slim display panel, an opening grip to its right, adjustable feet below, and side vents. The enquiry team supplies the upper limits of each range, the second supply version beside AC 110 V 60 Hz, the programme list, trays and water arrangements.

Its cabinet stands 450 mm high on a 710 × 505 mm base and weighs 58 kg. Medigear. UK offers it to buyers in more than 80 countries, and the enquiry team provides stock and lead time information.

Multi-chair dental practices, community dental services, oral surgery units and minor surgery or podiatry services are the buyers the DGT-23Z is built for. Their instrument mix of pouched sets, handpieces, and longer surgical instruments needs a vacuum-class steriliser and a chamber deep enough to keep pouches flat.

Survey evidence shows how often the match between steriliser and routine goes wrong. A study of 179 dental surgeries in Scotland found that most handpieces were processed in non-vacuum bowl-and-instrument sterilisers, and that 21% of surgeries were wrapping handpieces in paper pouches before sterilising them in those machines. The same survey programme found that 88% of benchtop sterilisers in those practices were non-vacuum types. Pouching before sterilising only works in a vacuum steriliser, so practices that want pouched handpieces and sets need this class of machine.

The fit runs the other way as well. A practice that sterilises only unwrapped solid instruments for same-day use, or processes a few loads a week, does not need a vacuum chamber of this depth. The DGT-23Z is aimed squarely at practices whose routine is pouch first, sterilise under vacuum, and store.

Before choosing, count the chairs the steriliser will serve, measure the longest instruments that must lie flat, and check that the team can fit a daily air removal test into its morning.

Tender specifications, including NHS ones, describe instrument mix, sterilisation classes,s and test requirements for benchtop sterilisers, and public buyers in other countries work the same way. The conformity documentation those procurement routes require is issued by the manufacturer and shared by the enquiry team.

Built Around Multi-Chair Workloads

The 23-litre chamber suits practices where several chairs feed one decontamination room. Pouches from a full session can be processed without splitting sets across extra cycles.

Depth for Long Instruments

At 450 mm deep, the chamber lets long forceps, elevators and surgical sets lie flat in their pouches. Pouches stay sealed and unbent through the cycle.

Handpieces and Pouches Together

Class B vacuum cycles cover hollow and wrapped loads in the same run. A practice needs one machine for its handpieces and its pouched sets.

A Clear Rule for Who Needs It

Pouching before sterilising requires a vacuum steriliser. Practices that work that way, or plan to, have a straightforward reason to choose Class B.

A Benchtop Cabinet

The unit occupies 710 × 505 mm of worktop and stands 450 mm high. It sits on a decontamination bench, so it doesn't require floor space.

Working Figures on the Sheet: The series rows list a

The DGT-23Z suits multi-chair dental practices, community dental services, oral surgery units and minor surgery or podiatry services that pouch instruments before sterilising, process handpieces in the same cycles and need room for long instruments. It is not the right choice for practices that sterilise only unwrapped solid instruments for same-day use, for very low volumes, or for teams without time for daily air removal testing. Before ordering, count the chairs it will serve, measure the longest pouched instruments, and check the bench, supply voltage, and water arrangements. Medigear.uk lists the DGT-23Z for business buyers worldwide and can arrange delivery, installation, commissioning, familiarisation and service cover. Ask the enquiry team for the range limits, voltage version, tray capacity, and EN 13060 evidence before ordering.

FAQ

Frequently Asked Questions

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

Multi-chair dental practices, community dental services, oral surgery units and minor surgery or podiatry services that seal instruments in pouches before sterilising and process handpieces alongside them. The 450 mm depth matters most where long forceps, elevators or surgical sets need to lie flat in their pouches.

When a practice reprocesses only unwrapped solid instruments and uses them straight away, a non-vacuum steriliser can do that job. It is also a poor fit for very low volumes, for benches that cannot take a 58 kg unit, and for teams without time for a daily air removal test.

Pouched instruments need to lie flat without bending the pouch, so their length sets a minimum chamber depth. At 450 mm, the chamber takes longer instruments and more pouches per tray layer; the enquiry team provides the number of trays and the maximum mass per cycle.

They give a design temperature of 139 °C, a rated working pressure of 0.22 MPa and a rated working temperature of 134 °C. The design pressure range begins at −0.1 MPa, showing the vessel is rated for vacuum, and the sterilising temperature, sterilising time and drying time ranges begin at 116 °C, 4 minutes and 0 minutes. The upper limit of each range is part of the information the enquiry team shares.

The voltage row begins with AC 110 V 60 Hz and lists a second version beside it. UK mains runs at 230 V 50 Hz, so ask the enquiry team for the version matching the local supply before ordering. On a 230 V supply, 2.2 kW draws roughly 10 A.

Yes. Class B under EN 13060 is the vacuum class for hollow and wrapped loads, which is why dental guidance pairs handpieces with vacuum sterilisers. Follow each handpiece manufacturer's reprocessing instructions, and run the daily air removal test before the first load.

A worktop at least 710 mm deep and 505 mm wide, rated for 58 kg plus water and a full load, with space left around the side vents. Two people should lift it into place. The quotation includes the water-filling and drainage arrangements.

EN 13060, under which Class B is the vacuum class for small steam sterilisers. Request the manufacturer's EN 13060 type-test evidence, and plan validation and periodic testing in line with the decontamination memorandum for the country: HTM 01-05 for England, SHTM 01-05 for Scotland, WHTM 01-05 for Wales.

Under the Pressure Systems Safety Regulations 2000 in Great Britain, a steam steriliser needs a written scheme of examination drawn up by a competent person. PUWER covers training and safe use, and the electrical connection follows BS 7671. Medigear.uk can arrange installation, commissioning and service cover.

A date and cycle reference on each pouch links it to the cycle record, so you can trace an instrument to the run that processed it. The enquiry team explains how the DGT-23Z outputs that record.

The DGT-23Z 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. That declaration names the legal manufacturer and should list EN 13060, EN 61010-1 and EN 61010-2-040.
