DURAN Test Tube Beaded Rim 21 mL 261302106

The DURAN Test Tube Beaded Rim 21 mL 261302106 is designed for laboratories that demand accuracy, cleanliness, and durability. Crafted from borosilicate glass, it resists thermal shock and chemical corrosion, maintaining optical clarity during repeated use.

Its beaded rim provides a reinforced edge, which prevents cracking and improves handling during heating or washing. With a 21 mL capacity, it is ideal for routine sample testing, reagent preparation, and small-volume reactions. Because it is autoclavable at 121 °C, it supports sterile operation and sustainable reuse across research and industrial environments.

The tube combines mechanical strength and high transparency, making it a dependable component of any analytical workflow.
