In this feature, Gary Partington, Extract Technology Sales/
Marketing Manager, looks into a simpler system of sterility
test isolators. Isolators are used to create an airtight barrier or
enclosure around a piece of equipment or process, to provide
absolute separation between the operator and product. According
to the author, an effective sterility test isolator for low-volume
testing can be a four-glove isolator with a main chamber with
a safety glass hatchback window. For high-volume testing, a
similarly operated isolator with six gloves or even half-suits can
be used. These simpler systems achieve the goal of eliminating
false positives during testing and a lower cost.
