Troubleshooting guide

■ To ensure consistent performance, do not apply silicone or vacuum grease to any
part of a QIAvac manifold. The spring lock on the top plate and the self-sealing
gasket (QIAvac 6S and QIAvac 96) provide an airtight seal when vacuum is
applied to the assembled unit. To maximize gasket lifetime, rinse the gasket free
of salts and buffers after each use and dry with paper towels before storage.
Table 4. Chemical-Resistance Properties of QIAvac Manifolds
Resistant to: Not resistant to:
Chlorine bleach (12%) Acetic acid* Benzene
Hydrochloric acid Acetone Chloroform
Sodium chloride Chromic acid* Ethers
Sodium hydroxide Phenol Toluene
Urea Concentrated alcohols*
* QIAvac 24 Plus is resistant to these chemicals.
