Tosoh Bioscience LLC: The Chemistry of Innovation

Molecular Weight Standards
Replacement Parts


The TSK-GEL standards product line consists of bulk quantities polystyrene and polyethylene oxide standards of varying molecular weight. For premixed PStQuick calibration standards click here. The standards are primarily used to calibrate size exclusion columns for subsequent analysis of unknown samples. The available polystyrene standards range from 400 to 21,000,000 Da while the polyethylene oxides range from 18,000 to 1,000,000 Da. All standards are tested to certify quality and reliability. Testing is done by laser light scattering, except for the standards below 1,000Da, which are tested by size exclusion chromatography.
