FAQs

1. What is the maximum temperature the Whatman POP TOP holder can withstand?

The holder is autoclavable at 121°C for standard sterilization cycles, maintaining structural integrity under repeated exposure.

2. Is this holder compatible with non-Whatman 13MM filters?

Yes, it is designed to fit most standard 13MM filter membranes from various manufacturers, though performance may vary slightly.

3. Can the POP TOP holder be used with corrosive chemicals?

It is resistant to most common lab solvents and mild acids/bases, but prolonged exposure to strong oxidizing agents may degrade the material.

4. How should the holder be cleaned between uses?

Rinse with deionized water, then autoclave or soak in 70% ethanol for 30 minutes. Avoid abrasive cleaners that may scratch the surface.

5. Does the holder require any special adapters for vacuum manifolds?

It fits standard 13MM filtration setups, but some older manifolds may require a rubber gasket for an airtight seal.
