5ml Screw-Cap Tubes with Flange (10 Pack, Pink Lid)

These 5ml screw-cap tubes feature a secure, leak-proof design thanks to a self-sealing cap and an integrated O-ring. Ideal for in-vitro diagnostics, sample storage, and transportation, these tubes and their caps are made from a chemically resistant, low-adhesion polymer. The incorporated flange provides stability, while convenient side ribs allow for one-handed opening. Compatible with most centrifuges and automated dispensing systems, these versatile tubes are a popular choice for a wide range of laboratory applications, including microbiological research. Their durable construction and leak-proof seal ensure sample integrity. Also perfect for home use, storing small items like beads, spices, and other materials.
