Because of its flexibility, durability, and biocompatibility, silicone tubes are highly esteemed. It can tolerate a broad temperature range which makes it an ideal option for varying conditions ranging from cold to hot. Its non-reactive surface and resistance to aging characteristics are beneficial for any delicate experiments or medical procedures that require ideal conditions.
Teflon (PTFE)
When exceptional resistance to chemicals is necessary, PTFE tubes become the ideal material. Its high level of inertness allows it to resist aggressive solvents and substances. This tube effortlessly manages exact fluid handling tasks involving corrosive materials, thanks to its low friction coefficient and non-stick characteristics.
Rubber
With its flexibility and elasticity, rubber is recognised for being versatile yet cost-effective. It's an ideal option for applications that require the ability to adapt easily. Rubber is frequently utilised in general lab environments as well as peristaltic pumps and other scenarios where priority lies with affordability paired together with pliability.
Factors to Consider When Selecting The Right Tubes
Selecting the right material is essential for the success of your scientific experiments. However, several additional factors must be considered to ensure optimal performance and reliability.
Chemical Compatibility
Selecting tubes with appropriate chemical compatibility is crucial. The material of the tube should not react or degrade when exposed to substances to ensure no issues arise during an experiment. Check the manufacturer's specifications for each tube you use, as they will indicate which chemicals are compatible and can be safely used without potential hazard.
Temperature Resistance
The temperature range of your experiment is another important consideration. The tubes need to possess the capacity to endure both their lowest and highest temperature limits without any softening, hardening, or distortion. Subjecting it to temperatures beyond its prescribed range could result in leaks, fractures, or hampered durability.
Flexibility and Durability
In many scientific applications, your tubes must possess both flexibility and durability as essential characteristics. In situations involving cramped spaces for installation or handling purposes, the capability to flex is crucial. Nevertheless, if a specific purpose necessitates fixed tubes to preserve structural strength, high rates of flexibility may not be appropriate.
Durability is just as important. Over time, wear and tear can lead to unexpected cracks, leaks, or breaks, which can seriously impact performance and safety. Ensuring your tubes can withstand long-term use is essential for maintaining reliability.
Size and Diameter
Flow rate and pressure requirements depend significantly on the diameter and size of the tubes. Insufficient flow can arise from small-sized tubes, while inadequate pressure could result from using overly large tubes. The appropriate size depends on the specific application and the desired flow characteristics.
Sterility and Cleanability
Maintaining a sterile environment is crucial in many scientific experiments. That is why these tubes must be cleanable and, if necessary, sterilisable to prevent contamination. Consider the ease of cleaning and sterilisation when selecting your tubes, especially for applications involving biological samples or sensitive materials.
By carefully considering these factors, you can choose the tubes that best suit your scientific needs and ensure the accuracy and reliability of your experiments.

When filling pipettes, transferring reagents, and carrying out other liquid-handling processes with minimal contamination are necessary tasks; these tubes prove to be very useful.
Gas Flow
Essential for gas flow management in experiments and maintaining specific atmospheres within systems, tubes also serve as a conduit to connect gas cylinders with experimental setups. It also delivers gases to instruments while regulating the rate of gas flow. However, the materials used for these tubes must be compatible with handled gases and capable of enduring required pressures.
Sample Transfer
In analytical chemistry and biological research, maintaining sample integrity is especially significant. Tubings enable the safe and efficient transfer of samples between different instruments or containers without contamination. These tubes facilitate the connection of sample vials with chromatography systems, the transfer of samples to spectrophotometers, or the transportation of biological fluids between diverse containers.
Automated Systems
In laboratory automation and robotic systems, tubes also play an important role by allowing seamless transportation of liquids or gases between various components.
