Convenient and efficient sample preparation: PCR tubes are small and easy to use, allowing for quick and efficient preparation of samples for PCR reactions.

Minimal sample loss: PCR tubes have a small volume, reducing the amount of sample needed and reducing the risk of sample loss during the reaction.

Improved thermal transfer: PCR tubes have a thin wall, which allows for improved thermal transfer and more consistent thermal cycling.

Cost-effective: PCR tubes are a cost-effective alternative to other sample preparation methods, and they can be purchased in large quantities at a lower cost.

Size and Volume: PCR tubes are small and have a low volume, typically ranging from 0.2 to 0.5 mL.

Material: PCR tubes are typically made of clear, medical-grade polypropylene, which is durable and resistant to chemicals and heat.

Wall thickness: PCR tubes have a thin wall, which allows for efficient thermal transfer during PCR reactions.

Resealable and Reusable: Some PCR tubes have a resettable cap that allows for repeated use, making them cost-effective.

Barrier properties: PCR tubes should have good barrier properties, protecting the sample from contamination during storage and transport.

Optical clarity: Clear PCR tubes are important for observing the reaction and determining the endpoint.

Sterilization: PCR tubes should be sterilized to ensure that they are free of contaminants that could affect the reaction.

Compatibility: PCR tubes should be compatible with the thermal cycler being used and the reaction conditions, including temperature, pressure, and other factors.
