Description

Product Overview UPDATE (Apr 2019): We have decided to discontinue the performance of a sterility test for our Pyrogen-free Tubes. As part of the production process, all glassware is depyrogenated at extremely high temperatures well in excess of standard depyrogenation process conditions. These conditions provide for ample assurance that the tubes are depyrogenated making them suitable for use when performing the Bacterial Endotoxins Test (BET). Therefore, there is no added value or additional quality assurance in subsequently performing a sterility test after processing. As a result, the Certificate of Analyses will no longer indicate the results of a sterility test for these products. The implementation date for this change was the end of April 2019. All test tubes are made from USP Type 1 flint borosilicate glass. Contain less than 0.005 EU/ml endotoxin. Product number N207 is recommended for dilution of endotoxin standards and test samples for all endotoxin detection assays. Product numbers N201 and N205 are recommended for use as reaction tubes in gel clot assays. Request More Info

FAQs

Question: What are the tube dimensions?

Answer:The tubes use a 10 × 75 mm format.

Question: What material is used?

Answer:They are made from borosilicate glass and supplied with screw caps.

Question: What are the tubes designed for?

Answer:They are intended for pyrogen-sensitive bacterial-endotoxin testing such as gel-clot LAL assays.

Application Note

These pyrogen-free borosilicate glass test tubes are designed for bacterial-endotoxin testing, including PYROGENT® gel-clot LAL assays. The tubes use a 10 × 75 mm format and are supplied with screw caps. They undergo high-temperature depyrogenation during manufacturing so the glassware is suitable for the Bacterial Endotoxins Test without introducing background endotoxin from the reaction vessel. The dimensions match the reaction-tube format used by standard PYROGENT gel-clot protocols. During a gel-clot test, samples and lysate are incubated in the tubes and then evaluated by inverting the vessel to determine whether a firm clot has formed. Using dedicated pyrogen-free glassware helps reduce contamination risk and supports reproducible interpretation of qualitative endotoxin results.
