Safe and Secure Solvent Delivery with a basic safety cap for glass bottles
Volatile organic solvents are essential for many lab instruments, including HPLC, LC-MS, FPLC, and SFC. However, their use poses significant health and safety risks. Our Solvent Extraction and Delivery Port Caps provide a dynamic, closed-system solution to safely manage these chemicals. Choose adapters based on your preferred tubing size. A set of plugs in included in our kits to maintain a closed system when holes are not in use.
Specifications:
fits glass solvent bottles with a GL-38 (38mm) threaded closure
3-ports, Type A (1/4-28 UNF) female threaded ports
PTFE insert for maximum chemical compatibility
Polypropylene outer spin collar prevents tubing from tangling
includes plugs
tubing adapters and venting filters sold separately
Port Caps for bottles with a GL-38 glass thread type
The GL38 glass thread is commonly used for 4-liter glass solvent bottles from most chemical suppliers and is valued for its secure fit with airtight safety caps, ensuring the safe storage of volatile chemicals. While the GL38 thread technically features a 38mm thread finish, its slightly different height makes it incompatible with the 38-430 threads on plastic lab bottles. Specifically designed for glass containers, GL38 threads are the correct choice for solvents, reagents, and other chemicals in most glass solvent bottles.
Our port caps are designed for “active” systems that continuously pump solvents. They offer a secure and effective way to extract and deliver pure reagents and solvents from their reservoirs to your instrument. Balanced to control airflow with effective mitigation of both evaporation and fumes, protecting lab personnel and preventing the loss of expensive reagents. Upgrade your lab’s safety and efficiency with our closed-system solution for solvent handling. Please note that caps without a built-in air check valve require an alternative way to accept air into the bottle as the solvent is displaced; such as part # WF-PR-115 air inlet valve or by attaching a nitrogen or helium gas line in order to sparge the solution prior to use.
Includes the following parts:
WF-GL38-3
BOTTLE CAP, GL38 3-ported 1/4-28, PTFE insert with polypropylene spin collar
WF-1428-PLUG-EA
(3) Plugs, 1/4-28 polypropylene
For labs which do not need to use groundable safety containers, we offer these port caps to adapt to standard drum and pail closures, as well as Nalgene® 83B, 53B, and 100-415 carboys. PLEASE NOTE THAT IT IS NOT POSSIBLE TO GROUND DRUM, PAIL, GLASS BOTTLE AND CARBOY (NON-JUSTRITE®) CONTAINERS; THIS MAY RESULT IN A SAFETY HAZARD WITH FLAMMABLE SOLVENTS.
PROP 65 WARNING: This product can expose you to chemicals including Tetrafluoroethylene PTFE, which are known to the State of California to cause cancer.
