• Come with PP sealing caps with silicone gaskets for extra leak protection when spinning >10,000 x g or spinning hazardous materials
• Autoclavable; transparent; Leakproof when used with supplied Nalgene closure†; Repeated autoclaving will reduce the life of PC centrifuge tubes.Ordering Information: Replacement sealing cap assemblies available for 30ml and 50ml sizes. Use Cat. No. DS3132-0020 for 30mL tube and Cat. No. DS3132-0024 for 50mL tube.Notes:
• Repeated autoclaving will shorten the life of polycarbonate centrifuge tubes.
• Must be filled to at least 80% total capacity for proper performance.
• Consult the Thermo Scientific Centrifugeware Chemical Resistance Table for chemical compatibility ratings.
• Cat. Nos. 3138-0050 is designed to fit universal rotors. Actual brim capacity of 3138-0050 is 42mL.† The term “leakproof” applies to Thermo Scientific Nalgene products that meet the following criteria: a) Bottle/flask/funnel closure systems with closures smaller than 100mm, after they are filled with water, inverted, withstand air pressure of 2psig for 2 minutes, and no water escapes;. b) Bottle/funnel/flask closure systems of larger than 100mm after they are filled with water, inverted for 15 minutes, and no water escapes. Note: these tests, using other liquids, may not yield the same results. To ensure safe usage, customers are advised to test Thermo Scientific Nalgene bottles and closures under conditions of their planned applications. Thermo Scientific Nalgene products are leakproof at ambient temperature and pressure when used with their Nalgene closures.
