These depyrogenated dilution tubes are made of high-quality borosilicate glass depyrogenated at 250 °C.

• Endotoxin-free test tubes (<0,001 EU/tube)
• Designed for all testing methods
• Made with borosilicate glass
• Can be used for general lab testing

This results in endotoxin-free tubes that can perform successful LAL dilution series, from creating the standard curve to sample dilutions, with minimal chance of potential contamination.
