Specifications
The core function of this product is to serve as an adapter for specific centrifuge tubes within a larger rotor system. The product details specify it as an adapter and spacer for use with round buckets 20300-142. Its primary purpose is to accommodate 1 x 25 mL Universal Tube. The Thermo Fisher Scientific Scientific No. is 75008196, and it’s listed as a unit of “Each (25 ML)”.
These specifications are critical because they define the precise application for which these adapters are designed. The 25 mL capacity is a significant factor, catering to researchers who often need volumes larger than standard 10 mL or 15 mL tubes but smaller than larger bottles. The designation as a “universal tube” adapter suggests it’s built to fit a common size, making it versatile within that specific volume. The “spacer” aspect implies it not only holds the tube but also fills any extraneous space within the bucket, contributing to a secure and balanced load.
The fact that the maximum speed and RCF are not listed for the adapter itself is standard, as these parameters are determined by the rotor and centrifuge, not the adapter. However, the implication is that the adapter is constructed to withstand the typical operating speeds and forces encountered by the Heraeus Labofuge 400/400R, which are designed for routine separations.
Performance & Functionality
In its primary job of holding a 25 mL universal tube securely within a round centrifuge bucket, this Thermo Fisher Scientific adapter performs exceptionally well. The fit is precise, meaning the tube is held upright and stable, preventing any tilting or tipping during acceleration and deceleration phases. This stability is paramount for achieving clean separation of sample components.
A key strength is its ability to facilitate the use of a specific tube volume that might otherwise be incompatible with the centrifuge rotor. It effectively bridges the gap between tube size and bucket configuration, enhancing the versatility of the existing centrifugation equipment. The adapter’s design ensures that the sample within the tube is not subjected to undue stress from a loose fit.
If there’s any weakness, it’s that the adapter is highly specific; it’s designed for one tube volume in one type of bucket. While this specificity ensures excellent performance for its intended purpose, it means it’s not a universal solution for all tube sizes or rotor types. However, within its designated application, its functionality is robust and reliable.
