Culture tubes are constructed of KIMAX-51® borosilicate glass for excellent chemical durability and resistance against sodium leaching.

Tubes feature sturdy, uniform bottoms and consistent lengths. The 6×50 mm tube is also known as a 'Durham' tube. The 10×75 and 12×75 mm tubes are suitable for cell washing procedures. Tubes are packed in convenient shrink-wrapped trays for ease of use on bench tops and in drawers, as well as to eliminate breakage and contamination.
