Thomson SINGLE StEP Standard Filter Vials

Recommended for samples containing less than 10% solid particulates.
Easy-to-use vials offer fast sample filtration and require only a squeeze of your fingers. 
Minimize sample loss by eliminating multiple transfers.
Color-coded caps allow easy identification of 0.2 μm or 0.45 μm membranes in PVDF, PTFE, PES, or nylon. 
Preslit PTFE/silicone caps help eliminate broken autosampler needles and cored septa. 
Rugged polypropylene vial houses insert with 450 μL loading capacity and low dead volume (120 μL). 
Fit most standard 12 x 32 mm autosamplers, including UHPLC instruments.
