The chamber shape is the point worth understanding first. This model measures 250mm in diameter by 450mm deep. Its sibling in the range holds a similar volume in a narrower, deeper chamber, so the two are not simply larger and smaller versions of each other. This one takes wider items; the other takes longer ones. A practice should choose on the shape of what it actually processes rather than on the litre figure alone.

Capacity is 22L. Machine dimensions are 780 by 420 by 512mm and net weight is 55kg.

Air removal is by pulsating vacuum, stated at minus 0.92 bar with a limiting vacuum of minus 0.96 bar. The vacuum system uses injection water pumping in an interlayer design, related by the manufacturer to higher working stability and a longer non-maintenance cycle.

Six sterilising programmes are provided. Universal runs 6 minutes at 134 degrees with 10 minutes drying and 3 pulses, Quick runs 4 minutes at 134 with 5 minutes drying, and Gentle runs 20 minutes at 121 for loads that should not see the higher temperature. A customs programme allows 115 to 134 degrees, 4 to 30 minutes sterilising and 1 to 6 pulses.

Two test programmes are built in. A Bowie and Dick test runs 3.5 minutes at 134 degrees and a helix test the same, the latter mattering for hollow loads. A vacuum test and a drying programme each run 15 minutes.

Steam temperature is settable from 115 to 135 degrees, sterilising time from 1 to 30 minutes and drying time from 0 to 30 minutes. A 0.22 micron filter treats air, the standard rating for retaining bacteria.

Water quality is monitored, which the manufacturer relates to avoiding secondary contamination of instruments caused by a water problem. A safety door interlock and automatic over temperature protection are fitted, English language operation is available, and a printer is optional.

The manufacturer states a Class B sterilisation standard. That is a classification claim, reported here and not endorsed; the supporting documentation should be reviewed by your own team. The electrical specification is not reproduced here.

Wide Chamber Geometry

The chamber measures 250mm in diameter by 450mm deep, giving 22L in a proportion that suits wider items rather than long narrow ones.

Pulsating Vacuum Air Removal

Pulsating vacuum is stated at minus 0.92 bar with a limiting vacuum of minus 0.96 bar, which the manufacturer relates to the best effect of sterilisation.

Interlayer Design

The vacuum system uses injection water pumping in an interlayer design, related by the manufacturer to higher working stability and a longer non-maintenance cycle.

Six Sterilising Programmes

Universal runs 6 minutes at 134 degrees, Quick runs 4 minutes at 134, Gentle runs 20 minutes at 121, and a customs programme spans 115 to 134 degrees.

Two Built In Tests

A Bowie and Dick test and a helix test each run 3.5 minutes at 134 degrees, with a separate vacuum test and a drying programme each running 15 minutes.

Adjustable Times and Temperature

Steam temperature is settable from 115 to 135 degrees, sterilising time from 1 to 30 minutes and drying time from 0 to 30 minutes as a load requires.

Water Quality Monitoring

A water quality monitoring system is fitted, which the manufacturer relates to avoiding secondary contamination of instruments caused by a water problem.

Door Interlock and Filter

A safety door interlock and automatic over temperature protection are fitted, with a 0.22 micron filter treating the air entering the chamber during a cycle.

Dental and Surgical Instruments

Operation appliances and dental instruments are both named on the card. A quick programme of 4 minutes plus 5 minutes drying is what makes chairside turnaround practical here, while three vacuum pulses handle the hinges and lumens that defeat a displacement machine. For a surgery working through a busy list, that combination decides whether one set of instruments can serve a whole clinical session at all.

Dressings and Glassware

Medical dressings, glassware and injection wares are all named, provided they endure high temperature and pressure. A 250mm diameter chamber takes wider glassware than any narrow bore chamber would, and the 10 minute drying on the universal programme matters for the dressings, since a damp pack can draw contamination through its own wrapping as it cools down afterwards upon a shelf.

Delicate Loads Needing Lower Heat

The gentle programme runs for 20 minutes at 121 degrees instead of 134. Trading time for temperature is exactly what some instruments need, since repeated exposure to the higher figure shortens the life of the fine tips and plastics. Having that as a named programme rather than something to configure each time means it actually gets used by busy staff rather than overlooked.

Research Units and Validation

A research unit is named alongside hospital use. Both a Bowie and Dick test and a helix test are built in, the latter being the one that matters for hollow loads, together with a vacuum test. A department that must demonstrate its process works therefore has the means to do so upon the very same machine that processes the work.

A Chamber Shaped for Wider Loads

Two models in this range hold a similar volume in quite different proportions, and that is a far more useful distinction than capacity alone. A 250mm diameter accepts wider trays, dishes and glassware that a narrower bore would refuse regardless of how many litres it claimed. Choosing on chamber shape rather than volume is the difference between a machine that fits your work and one that very nearly does.

The Water Is Watched

A water quality monitoring system is unusual at this level, and it addresses a very real failure mode. Poor water leaves deposits on the instruments and inside the machine, and the manufacturer relates that monitoring to avoiding secondary contamination of the load. An autoclave that tells you the water is wrong before it processes a tray with it saves both the load and the chamber itself over the years.

Testing on the Same Machine

A Bowie and Dick test for steam penetration, a helix test for hollow loads and a vacuum test are all built in. Where a practice must show its decontamination process works, having the tests on the machine that does the work is materially stronger than any procedure relying on separate equipment being borrowed, booked or remembered at the right interval by somebody.

The Visionstar KT-22 holds 22L in a chamber of 250 by 450mm, measuring 780 by 420 by 512mm overall and weighing 55kg. Pulsating vacuum is stated at minus 0.92 bar with a limiting vacuum of minus 0.96 bar in an interlayer design using injection water pumping. Six sterilising programmes run from a 4 minute quick cycle to a 20 minute gentle cycle at 121 degrees, with Bowie and Dick, helix, vacuum and drying programmes alongside them. Steam temperature is settable from 115 to 135 degrees, sterilising time from 1 to 30 minutes and drying from 0 to 30 minutes. Water quality monitoring, a safety door interlock, automatic over temperature protection and a 0.22 micron filter are fitted, with a printer optional.

Two points are handled deliberately. The manufacturer states a Class B sterilisation standard, which is a classification claim reported here and not endorsed, and whose documentation should be reviewed by your own team. The electrical specification is not reproduced here. Nothing on this page should be read as a claim about testing or regulatory approval.

If your practice or laboratory processes wider instrument trays, dressings or glassware, speak to Medigear.uk. As a verified medical equipment supplier working across medical, dental, rehabilitation and aquatic therapy settings, the team will confirm which chamber shape suits your loads.

FAQ

Frequently Asked Questions

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

The chamber measures 250mm in diameter by 450mm deep, giving 22L in total. The proportion matters as much as the volume, because a wider bore takes the wider trays, dishes and glassware that a narrow deep chamber of similar capacity would simply refuse to accept at all in ordinary practice.

By pulsating vacuum, which is stated at minus 0.92 bar with a limiting vacuum of minus 0.96 bar. Air trapped in a hinge, a lumen or a wrapped pack is what stops the steam reaching the surface beneath it, so repeated vacuum pulses extract it, where displacement alone would leave it in place.

Universal at 6 minutes and 134 degrees, then Quick at 4 minutes, Gentle at 20 minutes and 121 degrees, and a customs programme spanning 115 to 134 degrees with some 4 to 30 minutes sterilising. Bowie and Dick, helix, vacuum test and drying programmes are all provided alongside those as well.

A Bowie and Dick test and a helix test, each of 3.5 minutes at 134 degrees, plus a vacuum test running 15 minutes. The helix test is the one that really matters for hollow loads, and having all three upon the machine means validation does not depend upon any separate equipment being borrowed.

Because poor water leaves deposits upon the instruments and inside the machine. The manufacturer relates the monitoring system to avoiding any secondary contamination of the instruments caused by a water problem, so a supply fault is caught before it has spoiled a whole tray of clean instruments.

For loads that should not see 134 degrees at all. It runs 20 minutes at 121 degrees, trading time for temperature, which suits the fine tips and plastics whose life is shortened by repeated exposure to the higher figure across hundreds of cycles across a single year of ordinary clinical use.

English language operation is available on this model, which is worth confirming with Medigear.uk beforehand. Every member of staff who runs a cycle has to read the display, so interface language affects daily Every member of staff who runs a cycle has to read the display, so the interface language affects daily use rather more than most other specifications upon a sheet ever do.

The manufacturer states a Class B sterilisation standard. That is a classification claim, reported here and not endorsed by this listing at all, and the supporting documentation ought to be obtained through Medigear.uk and reviewed by your own team before any reliance at all is placed upon it.
