Bubble Trap Membranes for Bubble Trap Kit

Additional hydrophobic PTFE membranes for bubble traps.

5x PTFE membranes (bubble trap not included)

The membrane service time depends on the kind of fluid used. For pure water, the lifetime can be several months or years. Buffer solutions significantly reduce lifetime and it is strongly recommended to flush the Buble Trap with de-ionized/distilled water after use to prevent salt crystals from forming.

Replacing the membrane

Do not dismount the product until replacement of the membrane is needed.

Dismantling and mounting the trap without changing the membrane are likely to induce leakage.

1. Unscrew the center screw to separate the components of the trap
2. Remove the used membrane
3. Place a replacement membrane onto half of the trap
4. Carefully assemble the two parts of the trap together with the retaining screw Tighten the screw hand tight until a stop is felt
5. The Bubble trap is now ready for use
