Replace glass filtration assemblies with shatterproof, disposable vacuum filters that fit most GL45 bottles. Save time and improve lab safety.

• GL45 threaded for use with common laboratory bottles
• Sturdy, shatterproof, resistant to many common solvents
• Compatible with hands-free hardware
• Three membrane material options
• Safer and more efficient than glass filter flasks
• 90mm membrane diameter for super-fast flow rates

VWR® Solvent Filtration Bottle Top Vacuum Filters offer a revolutionary approach to bulk solvent filtration. Safer, faster, and easier to use than conventional glass filtration assemblies, VWR® Solvent Filtration funnels screw onto any vacuum-rated GL 45 threaded bottle. Simply plug the filter onto a vacuum line and begin filtering solvents without any complex setup. The FDA-grade polypropylene housing provides vastly improved chemical compatibility over traditional VWR® Vacuum Filtration Systems.

VWR® Solvent Filtration vacuum filters are a safe alternative to syringe filtration as well, using vacuum to filter a liter or more without the need for manual syringe work. The simple funnel design eliminates the risk of shattered glass, and makes cleanup as easy as throwing away the filter. And for users looking to completely revolutionize their solvent filtration, VWR® offers hands-free hardware that allows for filtration without any need for supervision. Choose from the bench-top Vacuum Filtration Pedestal (97066-232) or the adjustable-height Vacuum Filtration Cradle Ring (97066-234).

VWR® Solvent Filtration Bottle Top Filters are used in a huge variety of applications, including solvent prefiltration for HPLC mobile phase, winterization and lipid removal cold filtration, pigment removal, filtration of media and buffers, and any sterilization or particle removal of mixtures incompatible with standard polystyrene filters. The wide variety of membrane materials, pore sizes, and funnel volumes allows users to find the filter that’s best for any application.
