Ask -4.What benchtop autoclave should I use (class B, class S or Class N)?
What autoclave you should use is determined by the type of instruments that you sterilise.
If you sterilise Hollow Load Type A & B instruments, you will need an autoclave capable of running a Type B Cycle. These autoclave are usually called Class B sterilizers.
Typical users of autoclave class Bautoclaves include:
Cosmetic application (Including hair or nail salons etc…)
If you only sterilize unwrapped Non Hollow instruments, you only need an autoclave capable of running autoclave Class N Cycles. These autoclaves are usually called Class N Sterilisers. Not many new sterilizes are Class N, although many older sterilisers are. When purchasing a new autoclave to run Class N, it is best to purchase a autoclave Class S sterilisers as these can easily process such instruments.
Can a single sterilizer be used for multiple load types?
Generally all autoclaves are capable of sterilizing all types of loads, but in order to get the most from your considerable investment it is worth investigating what options might be available to more efficiently process the different types of materials. A waste load can be processed far more effectively by using options such as vacuum and free steaming, but using these on a media load could lead to disaster. Some laboratories use a different autoclave for each load type to avoid cross contamination, but for smaller laboratories this can easily be overcome by having pre-set selectable programs for each load type. Once programmed and ‘locked off’ these cycles can also be qualified.
Ask -5.What are the type A & B hollow instruments?
Hollow Load Type A
An object whose ratio of length of cavity to diameter is greater than 5.
Hollow Load Type B
An object whose ratio of length of cavity to diameter is greater than 1 and less than 5.
Non Hollow Instruments (Solid Instruments)
An object whose ratio of length of cavity to diameter is less than 1.

Ask -6.Top-loading autoclaves or front-loading autolcaves? Horizontal or vertical type autoclaves?
Many sizes of lab sterilizers are available as either top- or front-loading; which suits you best? Top loaders conserve space, but can be cumbersome if you process heavy loads. Front loaders can’t process as large a load at comparable volume, but pose less of a risk of strain or repetitive injury to technicians who handle many loads each day.
