The miVac range of centrifugal concentrators offers methods for drying aqueous and alcohol-based samples are included in all models. The units as a group provide capacity for 6 to 12 stacked shallow-well microplates or 64 to 200 micro centrifuge tubes of 1.5 ml size. LCD displays digital control and programming of time and temperature. Vacuum pumps to match are available, including 2-head and 4-head diaphragm pumps and an ultra-low vacuum scroll type pump. The concentrators will allow scientists working with DNA, RNA, peptides, oligonucleotides and proteins to safely and swiftly concentrate or dry their samples. In addition, a refrigerated cold trap will be available as an add-on unit to speed concentration and recover waste solvent. Modular design and a range of interchangeable rotors accommodate most applications.
