FAQ of 50ml Centrifuge Vials

Can 50ml graduated centrifuge tube be sterilized at high temperature and high pressure?

Yes. This product supports high temperature and high pressure sterilization at 121℃ for 15 minutes, which is suitable for laboratory sterility requirements such as cells and microorganisms. Before sterilization, please make sure that the cap is not screwed too tight to prevent deformation.

Can samples be frozen directly in centrifuge tubes after centrifugation?

Although they can be refrigerated for a short period of time, it is recommended that samples for long-term storage be transferred to dedicated cryotubes for better sealing and low-temperature tolerance.

Is the cap of the 50ml plastic centrifuge tube leakproof?

This centrifuge tube adopts a screw-on cap design with strong sealing. It can still effectively prevent liquid leakage at high speed. However, it is recommended to make sure that the cap is completely tightened before operation.

What is the main purpose of 50ml centrifuge tube?

1. Cell culture and collection

Used for the collection and precipitation of adherent cells or suspended cells, it can be operated with a cell scraper or cell culture bottle.

After centrifugation, the cells are recovered for passage, cryopreservation or subsequent experiments.

2. Biological sample stratification

When extracting plasma, serum, exosomes, tissue fluid, etc., 50ml centrifuge tubes can accommodate large volumes of samples, which is convenient for density gradient centrifugation or sample stratification.

3. Premixing and storage of buffers or reagents

Can be used for the preparation and temporary storage of liquids such as PCR buffer, lysate, culture medium, etc.

Especially suitable for operation scenarios where a pipette or filter tip is required to transfer liquids in large quantities.

4. Preliminary treatment of samples before freezing

As a transfer tube before freezing, it can carry samples for centrifugal concentration or mixing, and then transfer them to cryopreservation tubes and store them at -80°C or liquid nitrogen.

5. Centrifugation step in nucleic acid extraction/protein purification process

Used to collect DNA, RNA or protein precipitates. Also commonly used to remove impurities or supernatant after cell lysis.

6. Collection tube or temporary storage tube in experimental operation

Used to collect disposable waste liquid or store processed samples for a short period of time. Often used as spare tubes in laboratories for processing various non-standard samples.

What is the difference between 50 ml conical tube and round bottom centrifuge tubes?

Conical tubes 50 ml are suitable for:

Sample precipitation centralized operation, such as blood cell separation, protein precipitation, DNA extraction. When accurately quantitative sampling, the pointed conical bottom is convenient for fixed-point aspiration. In combination with cryo tubes or cryoboxes, it can be used for pre-treatment centrifugation.

Round bottom centrifuge tubes are suitable for: Scenarios that require frequent shaking or transfer, such as antibody incubation, cell labeling, and reagent dilution. Applications that reduce shear force, such as gentle washing of suspended cells or immunomagnetic bead separation.
