Bioprocess Gaskets & Silicone O-Rings for Laboratory Containers

Explore bioprocess gaskets and silicone O-rings designed to provide reliable sealing between compatible laboratory container closures, caps, and adapters. O-rings are important sealing components in laboratory liquid handling, media storage, chemical containment, and bioprocess applications where maintaining a secure container closure helps reduce the risk of leaks and contamination.

At LabSafetyShop, discover platinum-cured silicone replacement O-rings manufactured from USP Class VI silicone material. Available in 53B and 83B sizes, these sealing rings are designed for compatible laboratory bottle and carboy caps and adapters. Their flexible silicone construction helps create a seal when correctly installed and compressed within the intended closure assembly.

Whether you're replacing a worn bottle cap seal, maintaining a laboratory carboy closure, or selecting replacement components for a bioprocess container assembly, LabSafetyShop makes it easier to source dependable laboratory sealing O-rings and replacement gaskets.

Choose the appropriate O-ring size, material, closure compatibility, and operating conditions for your application. Always verify chemical resistance, temperature limits, and sealing performance before using replacement O-rings in critical laboratory or bioprocess operations.

Bioprocess Gaskets FAQ

Frequently asked questions about this collection.

What are bioprocess gaskets and O-rings used for?

Bioprocess gaskets and O-rings are sealing components used between compatible container closures, caps, and adapters. They help maintain a secure seal in laboratory bottles, carboys, and liquid handling assemblies, reducing the likelihood of leaks when correctly selected and installed.

What types of bioprocess gaskets are available at LabSafetyShop?

LabSafetyShop currently offers platinum-cured silicone replacement O-rings in 53B and 83B sizes. These products are intended for compatible laboratory bottle and carboy cap assemblies.

What is platinum-cured silicone, and why is it used for O-rings?

Platinum-cured silicone is a silicone elastomer manufactured using a platinum-catalyzed curing process. It is commonly selected for laboratory sealing applications because of its flexibility and suitability for appropriately specified container assemblies. The available O-rings are described as being made from USP Class VI silicone material.

What is the difference between 53B and 83B O-rings?

53B and 83B O-rings are designed for different compatible cap and adapter sizes. They are not interchangeable. Select the replacement O-ring that matches the specified closure assembly rather than relying only on the bottle's capacity or appearance.

Are silicone O-rings resistant to laboratory chemicals and solvents?

Silicone O-rings are compatible with many laboratory applications, but they are not universally resistant to all chemicals or organic solvents. Compatibility depends on the chemical, concentration, temperature, and exposure duration. Always verify the suitability of the sealing material before use.

When should laboratory bottle cap O-rings be replaced?

Replace an O-ring when it shows signs of cracking, permanent deformation, swelling, hardening, surface damage, or loss of sealing performance. Replacement may also be necessary after repeated cleaning or sterilization cycles, depending on the manufacturer's instructions and laboratory procedures.
