Our specialised Limulus Test Tube-S are made of high-quality borosilicate glass depyrogenated at 250 °C.

• Endotoxin-free test tubes (<0,001 EU/tube)
• Designed for gel clot, KTA and KCA testing on the Toxinometer®
• Made with borosilicate glass

These tubes have a special curvature that allows the appropriate amount of light to transmit through the sample to measure the endotoxin concentration based on the method used. This glass tube is designed for the Toxinometer® Measurement System.

The Depyrogenated Aluminum Caps assists in reducing the chance of contamination, preventing any additional substances or material from entering the testing tubes.
