Description
Product Overview
The ULAB Scientific Carboy Venting Cap (model UCA1004) is engineered to meet the rigorous demands of modern laboratory environments. Constructed from high‑grade polypropylene, the cap offers exceptional chemical resistance and durability, while the integrated TPE gasket ensures a tight, leak‑proof seal even under autoclave conditions. Designed to fit standard 5 L, 10 L, and 20 L carboys, the cap measures 98 mm in height and 102 mm in diameter, providing a universal solution for a wide range of glassware. The port caps are compatible with silicone tubing that has a 13 mm inner diameter, allowing for quick and secure connections without the need for additional adapters. With a package weight of just 3.53 ounces, the cap is lightweight yet robust, making it easy to handle during routine lab work. The product is not discontinued and has been available since January 2019, reflecting ULAB Scientific’s commitment to long‑term support and availability.
Usage
Designed for versatility, this venting cap excels in a variety of laboratory applications. Whether you are preparing culture media, handling hazardous chemicals, or conducting analytical experiments, the cap provides a secure barrier that prevents accidental spillage and exposure. Its quick‑fill feature enables rapid addition of liquids, reducing downtime and improving workflow efficiency. The cap’s leak‑proof design is especially valuable during autoclaving, where pressure changes can compromise traditional spigots. By replacing the spigot with this venting cap, users can safely sterilize liquids inside the carboy without risking leaks or contamination. The cap also serves well in field settings where a spigot‑less carboy is required, such as environmental sampling or mobile labs, offering a reliable seal that withstands transport and handling stresses.

FAQ
Can the venting cap be used with carboys larger than 20 L?
The cap is specifically sized for standard 5 L, 10 L, and 20 L carboys. While it may physically attach to larger containers, the seal integrity cannot be guaranteed, and we recommend using the appropriate size cap for volumes above 20 L.
Is the TPE gasket compatible with all types of chemicals?
TPE is known for its broad chemical resistance, handling most aqueous solutions, acids, and bases commonly used in laboratories. For highly aggressive solvents, we advise verifying compatibility with the specific chemical or consulting the material safety data sheet.
How does the cap perform during autoclave cycles?
The cap is designed to withstand typical autoclave temperatures (up to 121 °C) and pressure changes. The TPE gasket maintains its elasticity, ensuring a tight seal throughout the cycle, which prevents steam leakage and protects the contents of the carboy.
Can the venting cap be sterilized by methods other than autoclaving?
Yes, the cap can be sterilized using chemical disinfectants such as 70 % isopropyl alcohol or 10 % bleach solution, followed by thorough rinsing with deionized water. Ensure the gasket is fully immersed to achieve complete sterilization.
What should I do if the cap develops a leak after repeated use?
If a leak is observed, inspect the TPE gasket for signs of wear, deformation, or contamination. Replacing the gasket restores the seal. Should the issue persist, contact ULAB Scientific support for a replacement cap or further troubleshooting assistance.
