Designed for high-performance lab use, our 5ml and 10ml glass centrifuge tubes are made of premium borosilicate glass, built to withstand high relative centrifugal force (RCF). The precision-tapered conical bottom ensures optimal pellet formation and maximum sample recovery during sedimentation. Fitted with chemical-resistant screw caps, these tubes create an airtight seal to prevent sample evaporation and cross-contamination, ideal for clinical, chemical, and biological research.

Superior Thermal & Mechanical Stability for Critical Lab Work

Standard plastic tubes often struggle with chemical stress or extreme temperatures. Our glass centrifuge tubes are the reliable upgrade: made to resist thermal shock and a wide range of corrosive reagents, with heavy-wall construction engineered to handle the mechanical strain of high-speed centrifugation. For R&D teams, this means zero leaching and uncompromised sample purity—critical for sensitive analytical work like HPLC, GC, and high-precision diagnostic testing.

Precision Sealing & Optimized Sedimentation Geometry

A centrifuge tube’s performance lives or dies by its seal and shape. Our screw-thread neck delivers a secure, leak-proof closure that stays tight through vacuum or pressure changes. The conical bottom is precision-designed to concentrate solids into a tight, compact pellet at the base, making supernatant removal easier and more accurate. Whether you’re handling clinical sampling, blood separation, or chemical precipitates, this tube system delivers the professional-grade reliability you need for consistent, high-accuracy results every time.
