Optimal Design

Molded clear graduation on both filter tops and receiving bottles.

Angled hose connecter simplifies vacuum line attachmen. Hose adapters fit multiple hose diameters.

Bottle top filters have a neck size 45 mm and fit most 45 mm neck sized plastic and glass media

storage bottles.

Easy grip style receiving bottles can also be used as storage bottles.

Cap of receiving bottle is individually packaged to prevent contamination.

Receiving bottles maximum volume exceeds the maximum volume for filter tops, which eliminates overflow contamination.
