More customers are requiring that certain loads are totally dry at the end of the cycle.
Typical loads can be pipette tips, tubing, glassware, instruments and porous loads such as lab gowns and shoes. Vacuum alone (even using liquid ring pumps) will not achieve totally dry loads. The only way to dry loads effectively is by adding a steam jacket/heat source to the chamber. The heating effect of the steam jacket/heat source plus the high vacuum flashes off all residual moisture from the load, whilst minimising cycle times.
