Silicone Peristaltic Pump Tubing

Silicone Peristaltic Pump Tubing
Details:
The silicone peristaltic pump tubing is made from food-grade silicone material using a platinum vulcanization process, resulting in uniform wall thickness and excellent elasticity. Its core transmission principle involves the peristaltic pump rotor squeezing the tubing to create a vacuum, enabling pure physical transmission without valves or seals. This design prevents direct contact between the fluid and the pump body, eliminating cross-contamination at the structural level.

Product Structure

 

 

Main Material: High-purity food-grade silicone undergoes platinum vulcanization to achieve uniform molecular cross-linking, with no residual peroxides, ensuring biological safety and chemical stability.

Process Characteristics: Smooth and dense tube walls, with a diameter tolerance of ≤±0.05mm and a wall thickness tolerance of ±0.03mm. Excellent elasticity allows for high-frequency compression, reducing material residue and flow fluctuations.

Product Applications

 

Biopharmaceuticals and Laboratories

Transporting trace reagents and cell culture media in drug development with flow stability error <1%; high-purity models certified to USP Class VI for vaccine production, with extractables <0.1 ppm to prevent contamination of biopharmaceuticals.

Food and Beverage Industry

Quantitative filling of viscous materials such as jam and dairy products, with elastic adaptation to high-frequency squeezing to reduce residue; transmission of fermentation liquid in the brewing industry, resistant to alcohol corrosion without affecting flavor, compliant with FDA standards.

Electronics and New Energy

Transporting ultra-pure water and photoresist in semiconductor manufacturing, with low leaching characteristics to prevent silicon wafer contamination; transporting electrolyte in lithium-ion battery production, maintaining stable performance from -40°C to 200°C.

 

FAQ

 

Q: 1.Can silicone peristaltic pump tubes be used to transport strong acidic liquids?

A: They can withstand hydrochloric acid and sulfuric acid, but hydrofluoric acid will corrode silicone, so the medium composition must be confirmed in advance.

Q: 2.How to choose the diameter specification of silicone peristaltic pump tubes?

A: Match according to flow requirements: 1.6mm diameter is suitable for μL-level micro-transmission, and 12.7mm diameter can reach a maximum flow of 500mL/min. The specific selection needs to be confirmed with the pump head model and the viscosity of the transmission medium.

Q: 3.How much higher is the cost of silicone peristaltic pump tubes compared with ordinary rubber tubes?

A: The cost of high-purity models is about 2~3 times that of ordinary rubber tubes, but the service life is extended by more than 3 times, and there is no risk of eluate contamination, resulting in lower long-term comprehensive use costs.

Q: 4.Will high-temperature steam sterilization affect the service life of silicone peristaltic pump tubes?

A: Steam sterilization at 121℃ for ≤30 minutes is a normal operation with little impact on service life; for frequent high-temperature sterilization, it is recommended to choose enhanced products to extend the service cycle.

Q: 5.What to do if the flow rate decreases after long-term use?

A: It may be due to decreased elasticity caused by silicone aging. It is recommended to check if the tube wall is hardened or cracked, and replace it with a new tube in time to ensure transmission accuracy; for frequent occurrences, upgrade to fatigue-resistant enhanced models.

Q: 6.Do silicone peristaltic pump tubes support sterile packaging?

A: Yes. Medical-grade products can be provided with independent sterile packaging after γ-ray sterilization, which can be used directly in scenarios such as vaccine production and sterile filling after unpacking to avoid secondary pollution.

Q: 7.How to reduce residue when transporting viscous materials?

A: Choose models with ultra-smooth inner walls, and match the appropriate pump head speed (30~60rpm recommended). After transmission, reverse operation for 1~2 seconds can discharge residues; for high-viscosity materials , large diameters are recommended.
