The selection of appropriate consumables is a cornerstone of efficient and accurate laboratory operations. For blood collection tubes, the serum separator gel is a critical component that directly impacts sample quality and downstream testing. This guide is designed for laboratory procurement professionals seeking to make informed decisions when sourcing this essential reagent.

Serum separator gel serves a vital function: to isolate serum from blood cells after centrifugation, thus providing a pure sample for analysis. However, not all gels are created equal. Several key properties should be considered when evaluating potential suppliers and products.

Firstly, Specific Gravity is paramount. The gel's density must be precisely calibrated to fall between that of serum and blood cells. This ensures effective stratification during centrifugation. Deviations can lead to incomplete separation or the gel barrier failing to form properly, potentially contaminating the serum.

Secondly, Physiological Inertness is non-negotiable. The gel must not react with any blood components, analytes, drugs, or hormones. Any reactivity could lead to inaccurate test results, compromising diagnoses. Reputable manufacturers ensure their gel formulations are thoroughly tested for compatibility and lack of interference.

Thirdly, Thixotropy is a crucial rheological property. The gel should be viscous enough to remain in place at rest but liquefy under centrifugation, allowing for separation. Upon cessation of centrifugation, it must re-solidify to form a stable barrier. Predictable thixotropic behavior ensures consistent performance and simplifies laboratory workflows.

Fourthly, Adhesion and Barrier Formation are critical. The gel must adhere to the inner wall of the collection tube and form a continuous, impermeable barrier. This prevents any leakage or exchange between the serum and cellular layers during sample handling, storage, and transport.

Fifthly, Stability under various conditions is important. The gel should maintain its properties across a reasonable temperature range and not degrade during typical storage or transport durations. Understanding the shelf-life and recommended storage conditions is vital for procurement planning.
