HPLC Sample Evaporators
Provair Sciences has introduced a new version of its MiniVap and UltraVap blowdown evaporators that use warm air or nitrogen to speed up the evaporation of common HPLC solvents such as dichloromethane, methanol, and acetonitrile from sample vials, improving throughput and removing this common laboratory bottleneck.
Combining a new 48-well needle head with a dedicated HPLC vial holder that accepts 48 standard 1.5-mL vials transforms any MiniVap or UltraVap system into a high-throughput HPLC sample evaporator. Applications that will benefit from the new HPLC sample evaporators include pre-concentration prior to injection (to increase sensitivity) as well as evaporation to dryness of post-column fractions for recovery of compounds.
