Membrany PTFE do filtracji fazy ruchomej HPLC

Membrany zaprojektowane z myślą o rygorystycznych wymaganiach filtracji fazy ruchomej
HPLC mobile phase filtration membranes, a Pall Life Sciences product, are designed for the stringent requirements of mobile phase filtration.

Membranes are identical in composition and quality to those used in HPLC-certified Acrodisc™ syringe filters
HPLC certification assures that the filters will not add artifacts to your analysis
GH Polypro membrane is the best choice for filtering mobile phases
PTFE membrane provides the ultimate in chemical compatibility for filtering harsh chemicals and HPLC mobile phases
