High purity medical quartz tube is an irreplaceable key material in medical equipment and pharmaceutical processes. It is made from high-quality quartz with a silicon dioxide content of ≥ 99%, which has an extremely low coefficient of thermal expansion, excellent optical transmittance, and outstanding chemical stability. It is particularly suitable for medical scenarios that require high cleanliness, high temperature resistance, and corrosion resistance. From precision analytical instruments to bioreactor tubelines, high-quality quartz tubes are directly related to the precision and safety of medical processes.

FAQ

Q1: What is the core difference between medical grade quartz tubes and ordinary quartz tubes?  

A: Medical grade quartz tubes adhere to stricter standards in terms of impurity content (especially heavy metals), inner wall smoothness, thermal stability, and mechanical strength. Ordinary quartz tubes may contain trace metal elements, which can easily precipitate at high temperatures or in acidic or alkaline environments, affecting the purity of the drug solution or detection results.

Q2: Does the product support customized non-standard sizes?  

A: Yes, it is. We provide customized services with an outer diameter ranging from 1mm to 300mm and a wall thickness ranging from 0.5mm to 10mm. The length can be cut or processed into irregular structures (such as conical, bottom sealing, punching, etc.) according to customer needs, without additional mold costs.

Q3: Can high-purity medical quartz tubes withstand repeated high-temperature sterilization?  

A: Okay. The product can withstand temperatures of up to 1100 ℃ for long-term use and 1300 ℃ for short-term use. Its thermal expansion coefficient is only 5.5 × 10 ⁻⁷/℃, and it is not easy to explode after repeated rapid cooling and heating. It is suitable for high-pressure steam sterilization or dry heat sterilization environments.

What core problems can it solve for you?

-Avoid metal contamination: High purity materials ensure the precipitation of lead-free, arsenic, iron and other elements, ensuring the safety of drugs, blood or reaction media.  

-Corrosion resistance and long lifespan: Except for hydrofluoric acid and hot phosphoric acid, it hardly reacts with other acids and bases, greatly reducing the frequency of replacement.  

-Accurate optical detection: The transmittance in the ultraviolet to infrared band is greater than 90%, which does not interfere with the signal transmission of equipment such as spectral analysis and laser therapy.  

-Complex shape processing: can be made into spiral tubes, U-shaped tubes, capillary tubes, etc., suitable for different equipment structures.

Typical application scenarios

Medical analysis instruments: optical colorimetric cell of blood/urine analyzer, ICP-MS injection tube, high UV transmittance, smooth inner wall without liquid accumulation

Pharmaceutical Bioengineering: Fermentation tank sight tube, cell culture reactor sampling tube, resistant to 121 ℃ wet heat sterilization, no dissolved substances

Laser medical equipment: medical CO ₂ laser tube, fiber optic protective sleeve, high dielectric strength, good thermal stability

Dental and surgical equipment: light curing lamp light guide rod, minimally invasive surgical suction tube, precision inner diameter tolerance, high bending strength

Customer Application Case (Anonymous)

Case 1: A certain medical equipment company

-Requirement: Flow colorimetric quartz tube for fully automatic chemiluminescence immunoassay analyzer, with an inner diameter of 3.2 ± 0.02mm, a transmittance of ≥ 85% in the ultraviolet region at 220nm, and no scratches on the inner wall.  

-Solution: We have customized high-purity quartz tubes with an inner diameter of 3.18mm and a wall thickness of 0.8mm. The two ends are precisely chamfered and cleaned with ultrasonic waves and dust-free packaging.  

-Result: After customer installation testing, the signal noise decreased by 42%, and the CV value of colorimetric repeatability improved from 1.2% to 0.3%.

Case 2: A European bioreactor manufacturer

-Requirement: Embedded sampling quartz tube for disposable biological reaction bags, capable of withstanding 3 cycles of high-pressure steam sterilization and fitting snugly with silicone tubing without leakage.  

-Solution: We provide tube fittings with an outer diameter of 9.5mm and a length of 120mm. One end is designed with an inverted conical anti drop structure, and the outer surface is lightly sandblasted to increase the friction of the seal.  

-Result: The customer tested 30 batches of samples without any leaks or cracks.

Case 3: Laser Equipment Maintenance Center of a tertiary hospital

-Requirement: Replace the discharge quartz tube (outer diameter 22mm, length 450mm) in the previous CO ₂ laser therapy device, requiring resistance to high temperature discharge shock and no distortion of the spot mode.  

-Solution: We use the gas refining method to synthesize quartz tubes, and coat both ends with anti reflective films. The straightness of the tube body is controlled within 0.2mm/m.  

-Result: After installation, the output power fluctuation decreased from ± 8% to ± 2%, and the service life of a single unit exceeded 12 months.
