Characteristics of Collecting Tube

Collecting tubes are used in laboratory settings to collect and contain a liquid or gas sample. Some common characteristics of collecting tubes include:

Material: Collecting tubes are made of various materials such as glass, plastic, or metal, and are chosen based on the type of sample being collected and the purpose of the experiment.

Size: Collecting tubes come in a range of sizes, from small tubes for collecting small samples to large tubes for collecting larger volumes.

Volume: Collecting tubes are often marked with graduations to indicate the volume of liquid or gas that has been collected.

Cap or Stopper: Collecting tubes may have a cap or stopper to prevent evaporation or contamination of the sample.

Sterilization: Collecting tubes may be sterilized before use to prevent contamination of the sample.

Design: Collecting tubes may have specialized design features, such as a conical shape to facilitate the separation of liquid layers or a sidearm for connection to other laboratory equipment.


How to choose Collecting Tube

The choice of a collecting tube depends on several factors, including:

Sample type: The type of sample being collected, whether it is a liquid, gas, or solid, will influence the type of collecting tube used.

Purpose of experiment: The intended use of the collected sample, such as for analysis or storage, will determine the type of collecting tube required.

Chemical compatibility: The collecting tube must be chemically compatible with the sample being collected to prevent contamination or damage to the sample or the collecting tube itself.

Volume: The volume of the sample being collected will determine the size of the collecting tube required.

Sterilization requirements: If the sample needs to be sterile, the collecting tube must be capable of being sterilized or pre-sterilized.

Convenience: The collecting tube should be easy to use and allow for easy access to the sample, such as a tube with a cap or stopper.

Cost: The cost of the collecting tube should be considered, as well as the cost of any additional equipment required for use with the tube.
