Features:- Withstands temperatures from -135° to +135°C (-211° to +275°F)
- Round-bottom design allows Matched high-speed rotors
- Available in refrigerated or non-refrigerated centrifuges
- Comes with easy-to-clean polypropylene unlined caps for normal conditions at speeds up to 10,000 xg Provides leak-proof† protection
- When equipped with Nalgene sealing caps (sold separately), 30mL and 50mL tubes can be centrifuged at up to 50,000 xg
- Autoclavable; re-autoclavable Sterilization shortens the life of PC centrifuge tubes
- For superior leak protection at >10,000 xg, use a sealing cap or sealing cap assembly (sold separately).
Ordering information:
The 30ml and 50ml sizes have optional sealing cap assemblies. Use product number DS3132-0020 for 30 mL tubes and DS3132-0024 for 50 mL tubes.
Note:
- Item No. 3118-0050 and -0085 are suitable for universal rotors. The actual full capacity of the tube with product number 3118-0050 is 42mL. The actual full capacity of the tube with product number 3118-0085 is 81mL.
- Repeated autoclaving shortens the life of polycarbonate centrifuge tubes.
- The filling volume must reach 80% of the total capacity to work properly.
- Please consult the Thermo Fisher Scientific Centrifugal Ware Chemical Resistance Chart for chemical compatibility ratings.
† The term "leak-proof" applies to Thermo Scientific Nalgene products: a) For bottle/flask/funnel sealing systems with cap sizes less than 100 mm, when filled with water and inverted for 2 minutes at 2 psig gas pressure, the water inside will not escape; b) For For bottle/funnel/flask sealing systems with cap sizes greater than 100 mm, when filled with water, the water inside will not overflow if it is inverted for 15 minutes. Note: If other liquids are used for the above test, different results may be obtained. To ensure safe use, customers are advised to test Thermo Scientific Nalgene bottles and closures under planned application conditions. Thermo Scientific Nalgene products are leak-proof when used with Nalgene sealing caps at room temperature and pressure.
