Perform biopharmaceutical aseptic fluid transfer or sampling applications with the tri-clover flange of Thermo Scientific Nalgene PPCO Centrifuge Bottles, molded of translucent polypropylene copolymer. Ideal for large-volume cell harvesting, pelleting and protein purification, these translucent bottles are autoclavable and have excellent chemical resistance properties.
For low- to moderate-speed centrifugation of biological and chemical samples
Polypropylene sealing caps assemblies available for 250mL (DS3131-0038) and 1000mL (DS3132-0063) sizes for added leakproof† assurance at higher speeds and fill volumes
For proper performance, bottle must be filled at least 80% of total capacity, except for 3120-9500 which must not be filled more than 75% of total capacity
Alert: When spinning 250mL bottle in the Thermo ScientificTM SorvalTM GSA rotor, use of the Nalgene centrifuge bottle adapter (DS3125-0250) is required.
Recycling Information:
Nalgene reusable polypropylene(PP) and polypropylene copolymer (PPCO) centrifuge tubes are designed to last many spins under typical laboratory conditions. Yet, as with all durable products, they need to be retired and replaced eventually. These centrifuge tubes are recyclable in many communities. At end of product life, please wash and recycle your Nalgene PP and PPCO centrifuge tubes if services are available in your community.
† 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.
The extended lead-time is due to a significant drop in demand. Lead-times could be shortened if able to commit to a specified quantity.
