Filt r Vials Compatibility Chart
R = Recommended. No significant change observed in flow rate or bubble point of the membrane, nor visible indication of chemical attack.
L = Limited Recommended Use. Moderate changes in physical properties. The filter may be suitable for short term, non-critical use.
N = Not Recommended. The membrane may be unstable.
- = Insufficient Data. Information is not available. Trial testing is recommended.
