Vacuum Filtration Manifold - Filter Funnel Manifold - 1, 3 or 6 Branch - 300 mL

The Master Science Vacuum Filtration Manifold filters several liquid samples at the same time to collect bacteria, precipitates and other particles on membrane filters. Each funnel holder has its own stainless steel valve, so one vacuum pump can run all positions and any branch can be opened or closed separately.

Versions are offered with 1, 3 or 6 branches and with 300 mL funnels in borosilicate glass or SS316L stainless steel. All manifolds can be autoclaved at 121 °C for 20 to 30 minutes or sterilised with ethylene oxide.

Common Laboratory Problems and How This Manifold Helps

How the Master Science Vacuum Filtration Manifold improves filtration work:

• Filtering samples one by one: up to 6 branches work together.
• Needing a pump for each funnel: one pump serves the whole manifold.
• Leaks at the funnel joint: ground joint with clamp.
• Contamination between batches: autoclavable parts.
