VWR 47729-572 Culture Tubes Borosilicate 13 x 100 mm 9ml Sealed Box of 250

VWR Disposable Borosilicate Glass Culture Tubes - 13 mm OD x 100 mm Length, 9 mL Volume, Premium Type I Class A Glass, Round Bottom, Plain Neck (MPN: 47729-572)

The VWR International 47729-572 is an industry-standard, laboratory-grade 13 mm x 100 mm disposable glass culture tube with an approximate working capacity of 9 mL, precision-engineered for chemical mixing, biological culturing, tissue washings, and clinical sample storage. Fabricated from premium Type I, Class A borosilicate glass, these plain-neck tubes deliver exceptional thermal shock resistance and superior chemical durability against aggressive acids, alkalis, and organic extraction solvents. Featuring a uniform wall thickness distribution that handles physical centrifugation forces and thermal expansion, the round-bottom geometry is structurally optimized to clear out sedimentations and maximize sample recovery during chemical assays. The plain, beadless rim accepts standard laboratory closures, plastic caps, or plug stoppers for seamless workflow adaptability.

Technical Performance and Design

• Premium Type I Class A Borosilicate Matrix: Manufactured from high-purity borosilicate glass with a low coefficient of thermal expansion. This composition ensures excellent resistance to structural cracking or shattering when exposed to sudden, extreme temperature shifts or high-pressure autoclave environments.

• Chemically Inert Flow Path: Resistant to chemical leaching and ph drifts. The inner glass surface prevents secondary ion absorption or alkaline extraction, keeping delicate biological matrices, reagents, and standard chemical reactions unadulterated.

• Uniform Wall Thickness Integrity: Precision-drawn glass walls eliminate localized structural weak spots. This uniformity allows the tubes to sit comfortably inside standard centrifuge rotors and withstand baseline spinning stresses without fracturing.

• Plain Neck Rim Adaptability: Finished with a smooth, straight-cut plain top edge. This configuration accommodates a variety of push-on plastic caps, core plug stoppers, or film wraps, allowing laboratory technicians to choose their sealing style based on protocol requirements.
