Entris II Balances with External Calibration

MAXI Flex Tube Kit

MAXI Flex Tubes combine two modes of action: electro-elution of nucleic acid molecules from polyacrylamide or agarose gels and dialysis or buffer exchange of protein molecules. Flex Tubes allow rapid, secure, simple loading and recovery, with high performance as the most convenient, user friendly, electro-elution and dialysis system on the market.
