How to Choose Microcentrifuge Tubes for Sample Preparation: 1.5 mL Tubes, Racks, and Workflow Compatibility
Microcentrifuge tubes are used throughout small-volume laboratory work. They may hold a reagent aliquot for a few minutes, collect a pellet after centrifugation, support a DNA or RNA extraction step, or keep a protein sample organized before the next assay. Because they are familiar, inexpensive, and used every day, they are often chosen by size […]
Centrifuge Tube RCF Rating Explained: Why Maximum Speed Is Not the Only Selection Factor
A centrifuge tube can remain below its stated RCF rating and still become unreliable. The problem is not always the force number itself, but the workflow conditions behind that number. When laboratories choose centrifuge tubes, maximum RCF is often one of the first specifications they check. This is understandable. If a tube cannot tolerate the […]
Why Do Centrifuge Tubes Leak? Common Causes and Prevention Tips
Why Do Centrifuge Tubes Leak? Common Causes and Prevention Tips Centrifuge tube leakage is often noticed only after it begins to affect the workflow. A small trace of liquid may appear around the cap after centrifugation, recovery volumes may vary between tubes, or residue may be found in a rotor position after a run. The […]
Common Centrifuge Tube Problems in Routine Laboratory Use
Introduction In many laboratories, centrifuge tubes are treated as routine consumables that only attract attention when something visibly goes wrong. If a tube does not crack during centrifugation, leak after a spin, or show obvious deformation, it is usually assumed to be performing normally. In practice, however, many centrifuge tube problems begin long before a […]
Centrifuge Tubes Guide: Types, Sizes, Materials, and How to Choose the Right Tube for Your Lab
Selecting the right centrifuge tubes may seem straightforward, but for most laboratories it directly affects sample integrity, reproducibility, and overall workflow efficiency. From small-volume molecular assays to large-scale cell culture preparations, the demands placed on a tube—its material, capacity, cap design, and RCF tolerance—vary widely across applications. Subtle differences such as the clarity of the […]
Centrifuge operation and use matters needing attention!
Centrifuge is a very common laboratory separation instrument, widely used in biomedicine, petrochemical, agriculture, food hygiene and other fields.
