Designed to process 0.3 and 0.9 ml, 96-well REMP tubes, CSP8 heat sealer permits simultaneous sealing of 8 REMP tubes and thereby avoids need to seal entire 96-tube rack. Integrated technology ensures production of tightly welded, pierceable seals, and REMP tubes' small volumes allow for multiple aliquots of individual samples – avoiding freeze-thaw cycles. Also, size of instrument's polyurethane seals maximizes storage density.
