Eppendorf Centrifuge Rotor Seal Ring FA-45-30 CAUME 30‑Hole 5430/5427R

Description

Product Overview

The CAUME Eppendorf Centrifuge Rotor Seal Ring FA-45-30-11 is a precision‑engineered component designed specifically for the 30‑hole rotor configuration found on Eppendorf models 5430 and 5427R. Constructed from a high‑grade, chemically resistant polymer, the seal ring delivers a tight, leak‑free barrier that maintains the integrity of the rotor chamber even under the most demanding centrifugation cycles. Its dimensions are calibrated to match the exact tolerances of the rotor housing, ensuring a seamless fit that eliminates vibration and reduces wear on adjacent parts. The ring’s surface finish is optimized for low friction, which helps to preserve the balance of the rotor and contributes to smoother acceleration and deceleration phases. In addition to its functional attributes, the seal ring is lightweight, which minimizes the overall load on the centrifuge motor and can improve energy efficiency over long periods of operation.

Designed with laboratory environments in mind, the seal ring can withstand repeated exposure to a wide range of solvents, disinfectants, and biological samples without degradation. This durability translates into a longer service life, reducing the frequency of replacements and the associated downtime for critical research workflows. The product is supplied in a single‑piece configuration, ready for immediate installation, and includes a concise set of installation instructions that guide users through the proper seating technique to achieve optimal performance.

Usage

Laboratory technicians and researchers rely on the CAUME seal ring when performing high‑throughput sample preparation, cell culture centrifugation, and analytical protocols that demand precise separation of components. The seal ring is compatible with standard Eppendorf rotor accessories, making it a versatile addition to any lab that utilizes the 5430 or 5427R centrifuge models. Its robust construction allows it to function reliably in temperature‑controlled environments, including refrigerated or heated centrifugation processes, where maintaining a consistent seal is essential to prevent condensation or vapor loss.

Typical use cases include the separation of plasma from whole blood, pelleting of bacterial cultures, and clarification of protein extracts. In each scenario, the seal ring’s airtight performance helps to preserve sample integrity by preventing cross‑contamination and ensuring that the centrifugal force is applied uniformly across all samples. The component is also suitable for routine maintenance cycles; technicians can quickly replace the seal ring during scheduled service intervals, thereby restoring the centrifuge to peak performance without the need for specialized tools.

FAQ

Is the seal ring compatible with all Eppendorf centrifuge models?

The FA‑45‑30‑11 seal ring is specifically engineered for the 30‑hole rotor configuration found on Eppendorf models 5430 and 5427R. It will not fit rotors with a different hole count or geometry.

Can the seal ring be sterilized using standard autoclave procedures?

Yes, the polymer material is autoclave‑compatible up to 121 °C for 30 minutes, allowing you to sterilize the component without compromising its structural integrity.

What is the recommended replacement interval for the seal ring?

While the seal ring is designed for long‑term use, we recommend inspecting it after every 500 hours of operation or whenever you notice a decrease in sealing performance. Replacement should be performed as part of routine preventive maintenance.

Does the seal ring affect the balance of the rotor?

No. The seal ring is manufactured to tight tolerances that match the rotor’s balance specifications, ensuring that it does not introduce any imbalance during high‑speed runs.

What support is available if I encounter installation issues?
