Non-sterile Minisart® NY syringe filters are supplied in bulk packs. This reduces waste and makes the handling easier whenever the application allows clarification under non-sterile conditions, like this is the case for the majority of sample preparation steps prior to HPLC or GC analysis. The polyamide membrane combines fastest flow with low non-specific binding. Sartorius polyamide is exceptionally pure compared with other common hydrophilic nylon filters. Competitor nylon membranes are using raw materials which are especially interfere with LC | MS. The housing of the filter is made of PP (polypropylene) which is compatibility with harsh solvents, acids and bases.
