Blackstone E418

Product Code: STDI-SE-3718

Class N Benchtop Steam Steriliser From the HS-STE-E Series With a Drying Stage of 1 to 60 Minutes, 121 °C and 134 °C Programmes, a 250 by 350 mm Chamber, 1500 VA and a 33 kg Net Weight

The Blackstone E418 is an 18-litre autoclave with drying from the HS-STE-E series, a Class N design for unwrapped solid instruments. Its 250 by 350 mm chamber runs at 121 °C or 134 °C with adjustable holds, then dries the load for up to 60 minutes, a setting that can be cut to one. It draws 1500 VA and weighs 33 kg. Available through Medigear.uk.

The E418 is the 18-litre HS-STE-E autoclave with an added drying phase. It shares its chamber, programmes, and pressures with the E318: a 250 by 350 mm chamber, 30 to 60 minutes at 121 °C or 10 to 20 minutes at 134 °C, and steam at 1.1 or 2.1 bar. What it adds is a timed drying stage that defaults to 60 minutes and can be cut to as little as one.

That stage changes the routine after each cycle. Instead of coming out wet, instruments can finish drying in the chamber, reducing handling and helping meet the UK expectation that instruments are dry before storage or wrapping. Blackstone does not say how the drying works, whether by heating the chamber, moving warm air or releasing the door, and the method affects how well hinged and serrated instruments dry. Nor does drying change the Class N scope. Air removal decides whether pouches and lumens can be processed, so the E418 remains a steriliser for unwrapped solid items.

Time is the trade-off. At the default settings, a cycle at 134 °C spends 10 minutes holding and 60 minutes drying, and one at 121 °C spends 30 and 60, before heat-up and discharge are counted. The unit weighs 33 kg, a kilogram more than the version without drying, and draws the same 1500 VA.

Medigear.uk is asking Blackstone for the drying method, full cycle times, a nd the width, which the supplied drawing does not show legibly, before supplying his 18-litre autoclave with drying

The E418 is aimed at practices that process unwrapped solid instruments and want to spend less time drying them by hand. A compact 18-litre autoclave with drying suits examination kits, restorative instruments, forceps and scalers, and a load that finishes dry can go straight into covered storage or post-sterilisation wrapping. Handpieces, lumened items and pouched sets still need a vacuum steriliser, drying phase or not.

Setting the drying time is a local decision. A 60-minute default is generous, and many practices will want to shorten it once they know how dry their usual load comes out. That belongs in validation: run representative trays, then check hinges, serrations and the tray surface for moisture rather than guessing. EN 13060 includes drying among its performance requirements, so test evidence against that standard is worth requesting. Any instrument that leaves the chamber damp still needs wiping with a disposable, lint-free cloth, the method HTM 01-05 describes for non-vacuum units.

Throughput planning needs the full cycle time, which the sheet doesn't provide. With 70 minutes of hold and drying per 134 °C load at the defaults, a practice running many trays a day may need to trim the drying stage or stagger its loads. The routine UK duties still apply. The pressure vessel needs an examination scheme under the Pressure Systems Safety Regulations 2000, and HTM 01-05 expects the automatic control test to be run every day and each cycle to be recorded, by hand if no printer or data logger is fitted.

Medigear.uk has requested the drying method and cycle times from Blackstone so the practice can plan around them.

Built-In Drying

A timed drying stage lets loads finish inside the chamber rather than on a cloth.

Adjustable From 1 to 60 Minutes

Trim the drying time to suit the load once validation shows what is needed.

Less Handling After Each Cycle

Instruments that come out dry need less wiping, saving staff time and limiting contact with clean items.

Ready for Storage or Wrapping

A dry load is ready for a covered drawer or for packaging after sterilisation.

Two Steam Programmes

Both 121 °C and 134 °C are available, each with a hold that can be lengthened.

Automatic Discharge

Listed on the sheet as standard, pending confirmation of exactly what it does.

Standard Socket Supply

The 1500 VA rating suits an ordinary UK 13 amp outlet.

As Blackstone's 18-litre autoclave with drying, the E418 takes the E318's Class N design and adds a drying stage of up to an hour, adjustable down to a minute. For practices that currently dry every load by hand, that is the main reason to choose it, provided they accept longer cycles and keep to unwrapped solid instruments. It does not extend the unit to pouches or handpieces. Details of the drying method, the length of a complete cycle and the unit's width still need to come from Blackstone, together with EN 13060 test evidence and UKCA or CE marking. Medigear.uk has requested all of them and will pass them to the practice before any order.

FAQ

Frequently Asked Questions

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

Sixty minutes by default, with any setting from 1 to 60 minutes available. No extended Dry+ stage is fitted to this model, so the single drying phase is the only one available after each sterilising hold.

Blackstone does not say. Common approaches in non-vacuum units include heating the chamber walls after discharge, sometimes with the door opened slightly, or passing warm air through the chamber. The method affects how well hinges and serrations dry, so Medigear.uk has asked for a description and any dryness test results.

No. Drying removes moisture after sterilisation, but whether steam reaches inside a pouch or a lumen depends on air removal, and a Class N cycle has no vacuum stage. The E418 is for unwrapped solid instruments; pouched sets and handpieces need a vacuum steriliser.

The sheet gives only the adjustable stages. At default settings, hold and drying total 70 minutes on the 134 °C programme and 90 minutes on the 121 °C programme, plus heat-up and discharge. Shortening the drying stage brings those figures down considerably.

That depends on the load and on the drying method, which is not described. Check dryness during validation with the practice's own trays, looking closely at hinges, serrations, and tray surfaces. Wipe anything still damp with a disposable, lint-free cloth before storing.

HTM 01-05 lets dry, unwrapped instruments wait up to 24 hours in the surgery itself, or up to seven days in a clean area away from treatment, protected from contamination. Packaging them after sterilisation extends storage to a maximum of one year within a controlled system.

The drawing shows the body as 515 mm deep and 450 mm high, and requires 10 cm of clear space behind, beside, and above the unit. The drawing doesn't show the width. Net weight is 33 kg, and the 1500 VA rating sits comfortably within a UK 13 amp socket.

How the drying works, how long a complete cycle runs, the unit's width and side foot spacing, tray sizes, the reservoir, any recording option and the door safety features. A buyer should also ask for EN 13060 test reports (including drying), plus UKCA or CE marking, carton size, warranty, and delivery times.
