The TAC100 series liquid nitrogen anti-contaminators act as miniature cryo-pumps to minimize contamination in the vicinity of specimens within the transmission electron microscope (TEM) optical column. The TAC200 liquid helium anti-contaminators are used with helium cooling holders.
- Blades of the TAC100 series anti-contaminators can be fully retracted or positioned near the tip of the TEM specimen holder using a three position bayonet collar
- Blades can be configured as single, double, or tubular
- Stainless steel flexible bellows allows movement of blades in and out of the specimen area of the objective lens without loss of vacuum
- Conduction rod and blades are electrically isolated from the TEM, which allows the blades to be linked to a separate touch alarm to warn the user in the event specimen holder is tilted too far
