Outer PP cap, inner PTFE body.

• Simple and easy-to-use with no need for fitting nuts and ferrules (for ¹/₈" Ext. Ø semi-rigid tube). Tubing passes straight through the cap for a continuous fluid path
• Luer ports take standard male Luer components including a range of accessories for different tubing types and sizes
• Optional integrated check valve and filter enables pressure equalisation while keeping the system closed and preventing particulate contamination or evaporation of expensive or harmful chemicals
• A Luer connection solvent vapor trap can be used to contain / control vapor egress into the environment

Solvent waste caps are designed to suit a variety of common laboratory waste vessels. Because waste systems require positive pressure to be applied in pumping waste solvent into the bottle, a vent port is required to allow pressure equalisation. In order to control vapor in the environment released via the vent port, precautions for vapor containment should be made, such as placing the system in a fume hood or connecting a vapor trapping unit.
