Thermo Scientific 3140-0500 Nalgene Polycarbonate Centrifuge Bottles with Sealing Closure, 450 mL - Clear (Case of 24)

Ideal for large-volume processes such as cell harvesting, pelleting, and protein purification, Thermo Scientific Nalgene PC Centrifuge Bottles are molded of crystal-clear polycarbonate, which allows easy sample visualization and results in excellent mechanical strength. These centrifuge bottles are the perfect fit with Thermo Scientific Fiberlite carbon fiber rotors.

• Molded of polycarbonate for easy visualization of samples, these bottles are ideal for low- to moderate-speed centrifugation of biological and chemical samples
• Polypropylene sealing cap closure with silicone gasket adds leakproof† assurance at maximum speeds or when spinning hazardous materials
• Fill bottles to 80% of total capacity
• Autoclavable; Repeated autoclaving will shorten the life of PC centrifuge bottles.

Ordering Information:
When spinning 250mL bottle in a Thermo Scientific Sorvall GSA rotor, use of the Nalgene centrifuge bottle adapter (DS3125-0250) is required.

† 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.
