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.
