Proteomic CentriVap Concentrator Systems include all the concentration components necessary to begin operation except for the vacuum pump.The Refrigerated CentriVap Vacuum Concentrator concentrates multiple small heat-sensitive samples, such as RNA and proteins, using centrifugal force, vacuum and controlled temperature to -4 C (25 F).The DNA Rotor accommodates up to 60 each 1.5 ml and 72 each 0.5 ml microcentrifuge tubes.The CentriVap Cold Trap reaches -50 C (-58 F) for solvent recovery and to protect the vacuum pump by trapping moisture, vapors and corrosive fumes as they evaporate from the samples.
