Silicone Pump Tubing

A: Yes, products that pass FDA and USP Class VI certifications and have qualified extractable tests should be selected to ensure no components are released to contaminate the liquid medicine.

A: Standard food-grade silicone tubes can withstand temperatures ≤200℃ for a long time and 230℃ for a short time (<24 hours); industrial-grade ones may have slightly lower temperature resistance due to additives.

A: Mastflex products are usually superior in pipe diameter tolerance (±0.03mm), fatigue resistance test (≥1 million extrusions), and batch stability, making them suitable for scenarios with high repeatability requirements.

A: No. Chemical pump tubes are used in strong corrosion and high-pressure conditions, with a metal composite structure; silicone pump tubes are suitable for clean, low-pressure scenarios. Interchange will cause corrosion leakage or insufficient transmission accuracy.

A: Check if the pipe diameter matches the pump head (tolerance exceeding ±0.1mm may cause poor sealing); confirm if the extrusion pressure is appropriate; if elasticity decreases due to aging, replace with a new tube in time.

A: Not recommended. Ordinary silicone pump tubes may contain precipitates or particulate impurities, which will contaminate photoresist and silicon wafers; high-purity types (extractables <0.1ppm) should be selected, with confirmed low precipitation and anti-static properties.

A: Temperature: Long-term exposure above 200℃ will accelerate aging;
Medium: Contact with hydrofluoric acid or high-temperature strong alkali will shorten the service life;
Frequency of use: For high-frequency extrusion (>100 times/minute), it is recommended to choose fatigue-resistant models (such as Mastflex) to extend the replacement cycle.
