interchange. They are an excellent and more practical alternative to cotton wool plugs. Made
from chemically resistant plastic. Autoclavable. Supplied in packs of 100.
The BugStopper™ is a unique device which gives a simple and reliable way of venting your culture vessels. It is a reusable, sterile
closure, made from biosafe silicone rubber and incorporates a hydrophobic glass microfibre filter that provides an aseptic vent.
Available in two sizes, BugStopper will fit most widely used culture flasks. BugStopper allows air to enter and exit the flask while
excluding bacteria and viruses. This eliminates contamination of both the contents as well as the outside environment.
The self-healing silicone wall of the BugStopper can be pierced with needles for inserting a sample port or for gas infusion. This is not
recommended for the BugStopper 10 because of the wall thickness.
The BugStopper is easy to use; you simply push it into the neck of the flask and autoclave the entire vessel. It is also economical
because it can be autoclaved again and again without loss of performance. BugStopper 10 has an enhanced feature, a protective shroud covering the lip of the flask.
