Labconco offers a wide range of concentrators and evaporators to meet your sample prep needs. CentriVap Concentrators use a combination of centrifugal force, vacuum and heat to speed evaporation of small samples. RapidVap Evaporation Systems use combinations of dry block heat, vortex motion, vacuum or nitrogen blowdown to reduce samples to dryness or an endpoint volume. RevElution Bio-Concentrators use a patented wet foam elution process to rapidly and efficiently concentrate liquid microbial samples.
