Diba has released the Omnifit Labware T-series waste caps designed to maintain air quality and safety in laboratory applications.
The chemically inert caps trap and contain escaping vapour generated by high-performance liquid chromatography (HPLC) and other lab solvents.
A colour-changing indicator strip notifies laboratory 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 1/8in 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 comprising the seal.
A separate 1/4in-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 design is also said to prevent 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.
