Vi000352

One sterilizer with many advantages

  • No cheap compromises: Processes, measurements, fittings, stainless steel finishing and batch documentation compliant with DIN and industry standards
  • Fast closure - easy opening thanks to our Fingertip Quick Lock

The VARIOKLAV 75 S and 135 S steam sterilizers with their ultra-flat steam generators in their double bottoms combine the advantages of a double-walled device - low energy consumption, permanently ready for use, effective deaeration and drying by built-in jacket heater - with those of a single-wall device - fast cooling.

The chamber is free of furnishings and feed water and therefore easy to clean. The basic version features four sterilizing programs, two for liquids and one each for solids and for waste. Up to 16 programs can be stored by the control unit, depending on the modules and options installed. Up to eight pressure changes combined with effective steam flushing drive out the residual air from solids and waste, allowing faster heating by pulsating steam.

  • No feed water in the chamber, a great advantage during loading and unloading, low steam escape when lifting the lid
  • No heating elements in the chamber, no burning of agar


Advantages

  • Ultra-narrow design, only 500 and 600 mm in width
  • Innovative thermolock pursuant to TRB 402 for liquids
  • Automatic spent-steam condensation
  • Versatile control unit, simple for operators and flexible for lab management

And after your purchase?

Benefit from fast batch processing, low operating cost thanks to efficient steam management.

 

Vi000358Safety
The steam pressure on the lid is transferred with maximum safety to innumerably many points on the closing ring - not just to two positions as with clip locks
Two pressure sensors check for complete pressure release before the lid can be opened

Silicone seal movable by pressurized air:

  • uniform closing pressure, reliable seal
  • wedge-shaped profiles automatically retract the seal when the pressure is gone
  • long life

 

 

 

verschlussUnique Fingertip Quick Lock*
Never before has opening and closing a lid been so simple and convenient. When a button is pressed, a safety ring locks the lid. It is tensed pneumatically, circumferentially encloses the lid and places itself immovably inside the closing ring. A movable seal closes the sterilizing chamber, making it pressure-tight and vacuum-tight. * Design patent

 

Double bottom as steam generator
This ultra-flat double bottom rapidly generates steam - a new milestone in steam sterilizer technology. This gives the sterilizers an unusually compact design.

Advantages

 

  • Steam generation and chamber are separated - stores heat and feed water, preheats the sterilizing chamber, collects and separates condensate and permits the drying of solids
  • No contamination of feed waters by drop condensates, waste, or culture media, leaving the sterile supplies free of deposits by impure steam
  • Minimum water volumes in the steam generator make economic use of heating energy and reduce the amount of water used for fast cooling
  • Water level control by exploiting the differences in heat conductivity between water and steam - no maintenance
  • Fast heating and effective deaeration through tangential steam entry

Fitting blocks: e.g. Floor Drain Valve*

Drain valve in the chamber floor eliminates dead spaces and thereby non-sterilizing zones, ensures a sterile condensate and prevents the spread of pathogens. The valve seat closes directly inside the sterilizer and can be steam-sterilized from all sides.

A chamber sensor for the condensate temperature is integrated in the valve (flow sensor) and measures the temperature in the coldest spot - in the disposal line.

Drain valve is heated by double bottom - preventing agar deposits 
*Patent pending


Universal feed water connector

  • Optionally suction from non-pressurized reservoir or feeding via demineralized water feed
  • Integrated pump equalizes all pressure variations in external supply lines
  • Automatic level control before, during and after the process ensures that the system is permanently ready for use

Schema für Doppelboden und verfügbare Module

Separate steam generator control
A comprehensive program package for chamber and steam generation that controls both pressure chambers separately offers extra versatility.

Advantages

  • Preheating: Steam generator permanently ander pressure
  • More efficient air removal by faster pressure changes and shorter intervals, which is a great advantage especially when sterilizing waste in waste bags
  • Following sterilization, the chamber is free of condensate, which further reduces the amount of steam that escapes when the lid is opened and additionally helps avoid unpleasant odours when sterilizing waste
  • Shortens batch processing times by up to 30 %

 

 


verschluss2Opening aid
Opening aid actuated by pressurized air

  • Lid swings back on pressing a button
  • Raises lid by up to 60°

 

Aquastop at sterilizer water intake avoids water damage
and turns water supply lines off even in standby mode

 


Media temperature controlled timingvi000009
Product temperature is attained more quickly through controlled temperature increments. No overheating of medial, timer-controlled sterilizing times, includes flexible liquid sensor.
