Globe Scientific 0.45 µm Replacement Filter for Diamond SeroFlow Serological Pipette Controllers, 1/Pack

The Globe Scientific Replacement Filter (3389-FIL) is a 0.45 µm membrane filter engineered for the Diamond SeroFlow series serological pipette controllers. It traps aerosols and prevents liquid carryover into the controller mechanism during routine pipetting, sterile cell culture work, and reagent dispensing, keeping aspiration speed consistent and protecting the internal pump.

Frequently Asked Questions

Which pipette controllers accept the 3389-FIL filter?

This filter is designed for the Diamond SeroFlow series serological pipette controllers from Globe Scientific. It seats in the controller's in-line filter position and is intended specifically for that instrument family.

How often should the filter be replaced?

Replace the 0.45 µm filter whenever aspiration slows, when liquid contacts the membrane, or as part of a regular maintenance interval. Frequency depends on usage volume and the viscosity of liquids handled.

Is the filter supplied sterile?

No. The 3389-FIL is a non-sterile replacement filter. If your protocol requires sterile conditions, handle it under appropriate aseptic technique during installation.

How is the filter sold?

It is sold one filter per pack at the per-pack price shown. Order multiple packs to keep spare filters on hand for shared or high-throughput controllers.
