The concentrators assist with the helpful sample preparation for easier molecular biology and organic chemistry analyses. Designed to protect DNA, RNA, protein, and nucleotide temperatures, concentrators reduce the risk of sample dryness that could negatively impact tests. Providing reliable solvent reduction methods in order to condense the dissolved samples, columns and automatic vacuum centrifugal styles speed evaporation and full extraction processes. With or without graduations, columns feature different standard joint sizes to fit specific apparatuses.
