Open solvent bottles bear the risk of spilled chemicals or escaping solvent vapor. Omnifit® Labware connector screw caps and accessories help prevent these problems and offer the security of a safe and dependable solvent delivery system. The bottle caps can be either used on the supply side to provide a closed delivery system for the safe intake of solvents or for safe disposal of solvent waste, providing a closed waste system. An optional check valve and filter enables pressure equalization and prevents vapor escape.

What are the benefits of a closed system?

Safety - closed solvent supply systems prevent vapor escape into the atmosphere, protecting lab staff from exposure to toxic fumes

Contamination control - the ingress of particles is effectively prevented

Protection of mixing ratios - prevents the evaporation of solvents which leads to altered concentration of reagents or ratios of mixtures
  Where should you use a closed system?

HPLC - handling of the mobile phase on the solvent supply and waste side

Fermentation or culture preparations - processes which require sterile transfer of culture media or addition of reagents to closed systems

Laboratories - active in the fields of biotechnology, life sciences, analytical and clinical chemistry

All Omnifit® Labware bottle caps are equipped with a so-called "anti-twist" feature, allowing the body to spin freely within the cap.

The benefit of this design is that tubes no longer become twisted while the cap is fitted or removed from the bottle. Therefore fluid lines do not have to be disconnected before unscrewing the cap.

The inner body of each Omnifit® Labware connector cap is made from PTFE, providing the highest chemical inertness. PTFE also creates a reliable seal to the glass bottle with no need for extra seals or O-rings.

T-Series with Luer Ports

· Simple handling with no need for fitting nuts and ferrules. 1/8" OD semi-rigid tubing passes straight through the Luer port creating a continous fluid path.

· Luer ports accept standard male Luer components, including a range of accessories for different tubing types and sizes.

· An optional integrated check valve and filter enables pressure equalization whilst keeping the system closed and preventing particulate contamination or evaporation of expensive or harmful chemicals.

· An optional solvent vapor trap can be used to contain/control vapor egress into the environment.

  Q-Series with ¼"-28 UNF Threaded Ports

· Optional valves offer an easy on-off control of individual fluid lines, ideal for selecting flow or for closing off lines prior to removing caps to change or re-fill solvent bottles.

· Robust threaded ports for standard ¼"-28 UNF threaded fitting nuts and adaptors provide a secure connection ideal for repeated connect/disconnect.

· An optional screw-in check valve and filter enables pressure equalization while keeping the system closed and preventing both particulate contamination and evaporation of expensive or harmful chemicals.

   T-Series Waste Caps

Omnifit® Labware solvent waste caps are designed to suit a variety of common laboratory waste vessels. Due to the fact that waste systems require positive pressure to be applied in pumping waste solvent into the bottle, a vent port is required to allow pressure equalization. In order to control vapor in the environment released via the vent port, precautions for vapor containment should be taken, such as placing the system in a fume hood or connecting a vapor trapping unit. To control vapor escape:

· A solvent trap (Part # 009CF-TW) should be screw-fitted into the ¼"-28 UNF threaded vent port. As liquid enters the bottle by gravity flow or punp, vapor can pass through the trap, equalizing pressure. Dangerous solvent vapor is neutralized by the activated carbon contained in the unit.

· The integral break-through detector indicates by color-change when the vapor trap needs to be replaced. Once the active medium within the vapor trap has become saturated with solvent, the color change strip turns red, indicating that the unit must be replaced.

· Any unused port must be sealed using a Luer plug (part# 009LP) to prevent solvent vapor escaping directly into the environment. Note: The push-fit nature of the vapor trap and Luer plugs alows only low positive pressure to be applied to prevent Luer connections being loosened.
