Borosilicate clear glass tubes from Jinan Munan Pharma Glass Co., Ltd are manufactured to a 3.3 expansion coefficient formulation, commonly used in pharmaceutical and laboratory applications. These tubes are produced from high-purity silica and boron oxide, offering excellent resistance to thermal shock and chemical corrosion. The transparency allows for visual inspection of contents, and the surface is free of visible bubbles or striations when produced to specification.
The material conforms to the borosilicate 3.3 standard, with a linear thermal expansion coefficient of 3.3 x 10^-6 /°C between 0 and 300°C. Specific heat is approximately 0.233 kcal/kg°C, and thermal conductivity is 1.0 kcal/hr·m·°C. These tubes are designed for use in ampoules, vials, and tubing systems where low alkali leaching and inertness are required. They are not suitable for exposure to hydrofluoric acid or hot concentrated alkalis above 30% concentration.
Buyers include pharmaceutical manufacturers producing injectable drug packaging, research labs, and medical device assemblers. The supplier specializes in USP Type I compliant glass products and offers both clear and amber variants. Tubes are typically supplied in lengths of 1 to 3 meters, with diameters ranging from 6 mm to 100 mm. Packaging is in sealed plastic-lined cartons to prevent moisture ingress and contamination. Trade terms are FOB Qingdao or CIF, with MOQs varying by diameter and length.

Verify that the tubes meet USP Type I or EP 3.2.1 standards for pharmaceutical use. Request batch-specific material certificates showing alkali leachate levels, thermal expansion data, and trace metal content. Do not rely on supplier claims alone - demand documented test reports for each shipment. Confirm the annealing process and request polariscope stress images for critical applications.
Lead time is not specified; confirm production cycle and shipping schedule directly. Standard trade terms are FOB Qingdao, but CIF or DDP may be available. Payment terms typically require 30% advance, balance against B/L. Ensure packaging includes moisture barriers and internal cushioning to prevent breakage during transit. Request container loading photos and a packing list with tube lengths and quantities per carton.
Perform incoming inspection using a polariscope to detect internal stress patterns. Check for surface defects, bubbles, and edge chips under magnification. Test a sample tube under simulated thermal cycling conditions. Retain samples from each batch for quality audits. Request a certificate of conformity with material composition and thermal properties for regulatory compliance.
