Waste Bottle Cap Traps Harmful Vapours

To maintain laboratory air quality and safety, Diba has introduced the Omnifit® Labware T-Series Waste Caps. The chemically inert caps trap and contain escaping vapour generated by HPLC and other lab solvents. A colour changing indicator strip notifies lab personnel when it is time to replace the vapour trap.

The T-Series waste caps come in a range of bottle thread types and connect to 1/8” OD semi-rigid tubing without requiring additional fittings. The tubing pushes straight through the cap Luer ports to create a liquid- and vapour-tight seal. Other tubing sizes can be accommodated using a variety of adapters, without compromising the seal. A separate ¼”- 28 UNF thread port enables connection of a vapour trap and breakthrough indicator unit.

An activated carbon vapour trap isolates any solvent fumes and prevents escape from the system during pressure venting. When the trap becomes saturated, an integrated indicator strip turns red, alerting staff to replace the trap to prevent unintentional vapour breakthrough.

The unique design also prevents over pressurisation. As liquid is collected in the waste bottle, either under pressure or gravity feed, vapour is automatically vented to the trap to prevent explosions or injury.
