  VACUUM SUMMERY
  
  A vacuum autoclave operating in basic form is much like a direct steam autoclave. However, in the case of a vacuum autoclave, a liquid ring vacuum pump and associated control valves are added. These valves have to be different from those used in non vacuum autoclaves as they have to be leak free and bi-directional- in other words, be able to operate just as efficiently with vacuum and pressure either side.
  
  It is for this reason that Rodwell Scientific Instruments utilise ‘Pneu-valve technology’. The Rodwell ‘Pneu-valve’ system is designed to seal 100%- totally leak-free. The Pneuvalve system will function just as well will pressure or vacuum on either side. The majority of vacuum autoclave systems can not do this. This is why the Rodwell Pneu-valve system can draw almost absolute vacuum (typically –0.8 to -0.9bar), whereas many manufactures can only manage –0.4 bar. This ensures that there will be no cold spots, in even the most porous of loads and 100% sterilisation is achieved.
  
  There is another advantage of the Pneu-valve system- reliability. Many other valves can be affected by debris such as broken glass of lime scale. Pneu-valve will not. If debris does get caught within it, the valve still closes and crushes any debris out of the way as it does so.
  
  Finally, a steam supply is required. Ideally, this needs to be supplied to the autoclave at around 3.5 bar for the best steam penetration and drying properties. Obviously, a steam supply is not always available and if there is one, it is often unreliable. Therefore, to meet this demand Rodwell manufacture a range of heavy duty steam generating systems and accessories capable of generating steam to the correct volume and pressure, up to a maximum of 4 bar.
  
  There are many cheaper vacuum systems available; all designed with cost rather then performance in mind. However, the additional investment in a Rodwell vacuum system will save money and the aggravation associated with traditional vacuum autoclave systems. Financially speaking, a pay back period will be realised very quickly.
  - Greater reliability means reduced downtime and lower maintenance costs.
  - Not susceptible to load breakage’s or hard water problems.
  - Leak free operation ensures full vacuum is drawn every time and full sterilisation is achieved.
  - Modular ‘Pnue-valve’ design means repairs can be effected easily and cost effectively.
