What are Oakridge tubes?

Molded from durable, chemical resistant polypropylene, the tubes have round bottoms and consistent wall thicknesses for centrifugation at up to 50,000g when filled to 80% of their nominal capacity. …

Can you autoclave 50 mL tubes?

50 ml Centrifuge Tubes Polypropylene tubes can be autoclaved and will resist temperatures up to 121 °C; they will also resist acids, solvents and alkalies at room temperature.

Are polypropylene tubes autoclavable?

Polypropylene containers are autoclavable. The recommended autoclave cycle for empty containers is 121°C at 15 psi for 20 minutes. Care must be taken to allow free air circulation into and out of vessels during the autoclave cycle, especially during the venting and cooling stages.

Are centrifuge tubes autoclavable?

CAPP centrifuge tubes 15 mL can be sterilized by autoclaving in the temperature of 121°C for 20 minutes.

Can you autoclave Ppco?

Polypropylene copolymer labware and bottles are autoclavable. The recommended autoclave cycle for empty containers is 121°C at 15 psi for 20 minutes.

Can I autoclave Eppendorf tubes?

yes, they can be autoclaved. Eppendorf tubes aren’t that expensive. No point autoclaving them and re use. To be on the safe side, you should always autoclave the tubes before you use them.

Does polypropylene crack in cold weather?

One example: polypropylene, an inexpensive material often used in containers, toys, outdoor furniture, and recycling bins has a Tg of between -20 and 0 degrees C, so it can easily lose its molecular mobility and become shatter-prone on a winter day.

Does polypropylene get brittle?

Polypropylene and PVC are both plastics that are brittle at temperatures below freezing. Polycarbonate and PETG also have low brittleness temperatures.

How do you clean Eppendorf tubes?

centrifuge tubes for so long in 1 % nitric acid but rather that this will clean all of your (potential) previous deposits from them. The centrifuge tubes is made of polypropylene (PP). We always cleaned the bottles on arrival the same way as above (but used a 3% HNO3) and never used them twice.

How do you clear an ultracentrifuge tube?

We reuse Beckman ultra-centrifuge tubes to harvest lentivirus. To clean the tubes, we first submerge the tubes in 10% bleach for 30 mins, then rinse them with water completely. After that submerge the tubes into 70% ethanol for 30mins, then dry them in hood.
