KIMBLE® Heavy Duty Centrifuge Tubes

The tubes are manufactured from 33 expansion, low extractable borosilicate glass, which offers exceptional chemical resistance and thermal stability. This premium glass conforms to USP Type I and ASTM E438, Type I, Class A requirements, ensuring that your samples remain free from contaminants leached from the glass. To further enhance durability, the tops are designed with a beaded finish, providing extra mechanical strength and reducing the risk of chipping.

Features:

• Heavy-Wall Construction - Designed to handle higher centrifugation speeds without structural failure
• Beaded Top - Reinforced rim increases strength and durability during handling and cleaning
• Made from 33 expansion borosilicate glass to minimize leaching and withstand thermal shock
• Features a permanent marking spot for easy sample identification and organization
• Outside dimensions remain compatible with standard centrifuge rotors (17 mm x 118 mm), though the internal capacity is reduced due to the thicker walls
• USP Type I - High resistance to water and chemical attack
• ASTM E438, Type I, Class A - Standard specification for glasses in laboratory apparatus

Note: Because of the increased wall thickness, these tubes hold slightly less volume than standard-walled tubes with the same outer dimensions.
