FAQs
Q1: What is the exact difference between Hydrophilic PTFE and Hydrophobic PTFE filters?
A1: Hydrophilic PTFE is specially treated to allow water and aqueous solutions to pass through smoothly without requiring pre-wetting, making it ideal for standard laboratory mixtures. Hydrophobic PTFE, on the other hand, naturally repels water and is strictly designed for filtering highly aggressive organic solvents or for venting gases and air.
Q2: Should I select the 0.22μm or the 0.45μm laboratory membrane filter?
A2: It depends entirely on your procedural goals. You should use the 0.45μm membrane for general clarification and removing macro-particulates to protect HPLC columns. However, you must use the 0.22μm membrane if your protocol requires absolute sterilization, as it effectively captures bacteria and ultra-fine contaminants.
