- Greater chemical resistance than polycarbonate
- Can be autoclaved repeatedly last longer than polycarbonate tubes under conditions of repeated autoclaving
- Can be used up to 50,000 x g in refrigerated or non-refrigerated centrifuges (Must be filled to at least 80% capacity for proper performance)
- Come with PP sealing caps with silicone gaskets for extra leak protection when spinning >10,000 x g or spinning hazardous materials
Ordering Alerts: Optional sealing-cap assemblies available for selected sizes. Use DS3132-0020 (for 30mL tube) and DS3132-0024 (for 50mL Tube)
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.
