Rocker MF Magnetic funnels are easy to assemble and stable enough for one-handed operation. The MF3 has long stem with stopper, while MF3a has short stem without a stopper (direct connect).

Frequently Asked Questions
Q: Are magnetic filter funnels suitable for organic solvent filtration?
Solvent or acid filtration is not recommended, as such use could greatly reduce the lifetime of these funnels.
Q: Can magnetic filter funnels be autoclaved?
PES MF funnels can withstand multiple autoclave cycles at 121 - 123 °C (250 -253 °F) at 1.0 bar (100 kPa, 15 psi) for 15 - 20 min. Please remove the lid kits and stoppers before autoclaving. Do NOT autoclave these funnels with aluminum foil.
Repeated used of detergents may cause polyphenyl sulfone to crack, especially those containing polyoxyethylated alkyl phenols and alcohols, anti-corrosion, or anti-scaling boiler additives.
