Can you centrifuge glass tubes?
Caution: Do not centrifuge glass tubes at forces above 2200 RCF in a horizontal head (swinging bucket) centrifuge as breakage may occur. Glass tubes may break if centrifuged above 1300 RCF in fixed angle centrifuge heads. BD Vacutainer® Plus Tubes will withstand up to 10,000 RCF in a balanced centrifuge.
What sizes are centrifuge tubes available in?
Centrifuge tubes range in capacity typically from a few milliltres up to 50mL. Centrifuge tubes may be supplied with plastic caps, which can be leakproof, screw-threaded, plug seal or push-on.
What is the minimum number of centrifuge tubes?
To transfer a solution, the stirring rod touches the delivery point of the reagent vessel and the wall of the receiving vessel. __________ TRUE OR FALSE __________ 11. The minimum number of centrifuge tubes in a centrifuge machine during its operation is one.
How do you sterilize centrifuge tubes?
CAPP centrifuge tubes 15 mL can be sterilized by autoclaving in the temperature of 121°C for 20 minutes.
What is the recommended centrifugation temperature for sst 2?
Mixing recommendation: SST™ II Advance tubes should be gently inverted 180° and back 5 to 6 times. Centrifugation instructions: Plus SST™ II Advance tubes 1300g to 2000g for 10min at 25°C room temperature.
How big is a 50 mL tube?
All of the 15 ml and 50 ml tubes are RNase, DNase and pyrogen free. The 15 ml tube dimensions are 17 mm x 120 mm long and the 50 ml tubes are 30 mm x 114 mm long. All of the caps are made of high density polyethylene.

What is supernatant in centrifugation?
The supernatant is the clear liquid that lies above the solid residue after centrifugation, precipitation, crystallization or settling. The liquid is normally free of precipitate and has a lower density.
Do centrifuge tubes need caps?
For aerosol-tight centrifugation, both aerosol-tight caps or lids and suitable vessels must be used. Every vessel has a maximum filling volume, usually two-thirds or 80% of the total volume (called the “working volume”) that shouldn’t be exceeded; this ensures the liquid in the vessel does not touch the vessel lid.
What happens if a centrifuge is unbalanced?
Unbalanced centrifuge rotors can result in injury or death. Sample container breakage can release aerosols that are harmful if inhaled. To avoid injury, workers should follow the manufacturer’s operating instructions for each make and model of centrifuge that they use.
How do you balance 3 centrifuge tubes?
How to balance a centrifuge
- Ensure all sample tubes are evenly filled.
- For each tube inserted in the rotor, add a tube of equal weight directly opposite it.
- Rotate the rotor 90° and add two additional tubes directly opposite one another.
- Repeat.
What is a centrifuge tube made of?
