FAQs
What’s the difference between ME25 and ME25/21 ST filters?
The ME25/21 ST version comes pre-sterilized, while standard ME25 filters require autoclaving before use. Both share the same 0.8µm pore size and material composition.
Can these filters be autoclaved?
While pre-sterilized filters don’t require autoclaving, they can withstand standard autoclave cycles (121°C for 15 minutes) if needed for specific protocols.
What’s the maximum pressure these filters can handle?
They’re designed for standard vacuum filtration (up to 700 mmHg) and can handle moderate positive pressure in syringe filter applications.
Are these filters suitable for protein binding studies?
No, for protein work we recommend low-protein-binding membranes like PVDF. These cellulose ester filters may bind proteins nonspecifically.
How should I dispose of used filters?
Follow your lab’s biohazard waste protocols. Used filters should be autoclaved or chemically disinfected before disposal if they’ve been in contact with hazardous materials.
