Programmable Vacuum Autoclave, Single-Lever Lock

Worth knowing before you order

The vacuum stages are the whole point of this machine and worth being clear about. A gravity-displacement autoclave relies on steam pushing air downwards out of the chamber, and it cannot reliably clear air from a wrapped pack, a length of tubing or a filter housing — residual air means the load never reaches sterilising temperature even though the chamber gauge says it did. A pre-vacuum machine pulls that air out first. If your loads are unwrapped media bottles and glassware, the simpler vertical autoclave also listed here does the job for less. Two things the flyer does not state: chamber volume and pressure rating. Both are quotation items, so tell us your largest load. And "21 CFR Part 11 software" describes what the software can do — audit trail, electronic signature, access control. Part 11 compliance is something your site demonstrates through validated use, not something a machine arrives holding, and air removal in particular has to be proved on your own loads with a Bowie-Dick or equivalent air-removal test.
