Laboratory specialized sample bottle specifications vary, and the specific selection typically depends on the experiment's requirements and procedures. Here are some common specifications for laboratory specialized sample bottles:

• 2ml, 5ml, 10ml, 20ml Eppendorf centrifuge tubes: Used in biology, molecular biology, and other experiments, especially in centrifugation operations.

• 15ml, 50ml centrifuge tubes: Used for large-capacity centrifugation operations, suitable for separating cells, precipitates, etc.

• 2ml, 5ml, 10ml, 20ml, 50ml test tubes: Commonly used for mixing, storing, and heating samples, suitable for various experimental operations.

• 1.5ml, 2ml microcentrifuge tubes: Used for handling small volume samples, such as microbiology and molecular biology experiments.

• 50ml, 100ml, 250ml, 500ml blue cap bottles: Typically used for long-term storage of samples, especially liquid samples.

• 2ml, 5ml, 10ml, 20ml, 50ml polypropylene sample bottles: Possessing good chemical inertness, suitable for storing various chemical reagents.

• 5ml, 10ml, 20ml, 40ml glass test tubes: Suitable for experiments requiring optical detection or with specific requirements for chemical reagents.

• 2ml, 5ml, 10ml, 20ml, 50ml cryogenic storage tubes: Used for low-temperature storage of samples, preserving the activity and stability of the samples.

Please note that these are just some common specifications, and the actual selection may vary based on the specific requirements of the experiment, including different specifications and materials for sample bottles.
