Visionstar LS-HG

Steam Water Inner Circulation

The manufacturer describes an inner circulation system with no steam discharge, which it relates to a clean and dry environment for sterilising work.

Computer Controlled Door Lock

A door safety lock system is described as automatically controlled by computer, preventing the vessel being opened while it remains under pressure.

Quick Open Hand Wheel Door

A hand wheel type quick open door structure is fitted, with a self inflating type seal closing the door before pressure is raised within the chamber.

Four Chamber Capacities

Volumes of 35L, 50L, 75L and 100L are offered, with chamber dimensions rising from 318 by 450mm to 440 by 650mm across the four models in the range.

Shared Operating Parameters

Working pressure is 0.22 MPa and maximum working pressure 0.23 MPa on every model, with a working temperature of 134 degrees and heat average within plus or minus 1 degree.

Extended Timer Range

Timer range is listed as 0 to 99 minutes or 0 to 99 hours 59 minutes, allowing processing that continues well beyond the length of an ordinary working day.

Drying Function and Protections

A drying function is described, alongside over temperature and over pressure auto-protection and safe protection of water lacking on every unit in the range.

LCD Display and Baskets

Working status appears on an LCD display with touch type keys, the unit shuts off with a beep once complete, and two stainless steel sterilising baskets are supplied.

Rooms Where Venting Is a Problem

This is the clearest case for choosing this range. A vessel that discharges steam at the end of every cycle raises humidity and needs ventilation sized to cope with all of it, which is difficult in a small laboratory, in a converted room or in a basement plant space. A system that recirculates internally removes that requirement, and for a site where extraction would otherwise need installing, the saving is a structural one and not merely a convenience.

Laboratory Media and Long Protocols

A timer reaching 99 hours 59 minutes points at laboratory work rather than instrument processing. Media preparation, extended holding and protocols running across several days are all supported, and because no steam at all is released at all, the vessel can run unattended overnight without leaving a room damp by the morning for whoever opens up the following day to find a damp room.

Wrapped and Packaged Loads

A drying function is described, which matters for anything wrapped. A pack leaving an autoclave damp can draw contamination through its wrapping as it cools, so drying completes the process for packaged items in a way that the sterilising stage alone does not. Combined with the closed circulation, loads and room both stay dry.

Busy Departments Opening Frequently

A hand wheel quick open door opens in one movement, and a computer controlled safety lock removes the risk of the vessel being opened while pressurised. For a unit cycling repeatedly through a session, that combination saves genuine time at every single opening, and it removes a real hazard from the working day entirely.

The Room Stays Dry

No steam discharge is the reason to choose this range over a conventional vessel. Repeated steam releases raise humidity, mark ceilings, and in a confined space make an unpleasant working environment that ventilation must be sized to handle. A closed circulation system removes the problem at its source rather than managing it afterwards, and it is the kind of feature whose value becomes obvious only to those who have worked for a while without it.

Control Handled by the Machine

A computer controlled door safety lock, automatic shut off with an audible reminder, over temperature and over pressure auto-protection and water lacking protection together mean the vessel manages its own cycle and its own safety. For equipment running repeatedly while staff are occupied elsewhere, protections that act rather than merely indicate are what keep both the operator and the processed load safe.

Drying and Timing for Real Work

A drying function and a timer reaching almost a hundred hours cover the two things that separate laboratory and packaged load processing from simple instrument cycles. One vessel handles a short instrument run, a long media protocol and a wrapped pack that must come out dry, and the shared parameters across all four capacities mean the same is true whichever size a department chooses.
