MUHWA Lab Safety 3 Port Cap with 1/4-28 Insert PEEK for 1/8″ OD Tubing

Description

Product Overview

The MUHWA Lab Safety 3 Port Cap is engineered to meet the rigorous demands of modern laboratory environments. Constructed from high‑quality materials, the cap incorporates a precision‑machined 1/4‑28 threaded insert that provides a secure and leak‑free connection to 1/8″ OD tubing. The inclusion of a PEEK (polyether ether ketone) fitting ensures exceptional chemical resistance, high temperature tolerance, and long‑term durability, making it suitable for a wide range of analytical and preparative applications. The GL45 sealing mechanism further enhances reliability by delivering a tight, repeatable seal that prevents contamination and loss of valuable samples. Each cap is supplied with three strategically placed ports, allowing simultaneous filling, venting, and pressure monitoring, which streamlines workflow and reduces the need for multiple accessories. The compact dimensions (1.97 x 1.97 x 1.97 inches) and lightweight design (1.76 ounces) facilitate easy handling and storage, while the blue polypropylene collar provides a visual cue for proper orientation during installation.

Usage

Designed for versatility, the MUHWA 3 Port Cap excels in a variety of laboratory settings, including chemical synthesis, biological sample preparation, and analytical testing. Its robust construction makes it ideal for use with glass bottles, syringes, and specialized reactors that require a GL45 closure. The cap’s three‑port configuration enables users to introduce reagents through one port, vent excess gas or liquid through a second, and monitor pressure or temperature through the third, all without removing the cap. This functionality is particularly valuable in sterile environments where maintaining a closed system is critical. The cap is also compatible with standard laboratory equipment such as magnetic stirrers, heating mantles, and vacuum manifolds, allowing seamless integration into existing workflows. Whether you are conducting high‑throughput screening, preparing calibration standards, or performing delicate titrations, the MUHWA cap delivers consistent performance and helps minimize the risk of sample loss or cross‑contamination.

FAQ

What tubing sizes are compatible with this cap?

The cap is specifically designed for 1/8″ outer diameter (OD) tubing, which is a common size for many laboratory applications. The 1/4-28 threaded insert provides a secure fit for standard fittings that match this tubing dimension.

Can the cap be used with chemicals that are corrosive?

Yes. The PEEK fitting and the polypropylene collar are both highly resistant to a wide range of chemicals, including acids, bases, and organic solvents. This resistance helps maintain the integrity of the seal and prevents degradation over time.

Is the cap suitable for high‑temperature processes?

Absolutely. PEEK retains its mechanical properties at elevated temperatures, making the cap appropriate for processes that involve heating, such as reflux or thermal cycling, without compromising the seal.

How many ports does the cap have and what are their functions?

The cap features three ports. One port is typically used for introducing liquids or gases, the second serves as a vent to release excess pressure, and the third can be used for monitoring pressure or temperature, allowing comprehensive control during experiments.

What warranty or support does MUHWA provide?

MUHWA offers a standard warranty that covers manufacturing defects and provides access to technical support for installation guidance, troubleshooting, and any questions related to product performance.
