Glass tube
The glass tube offered by Shenzhen Solarvalley Scitech Development Co., Ltd. is supplied from China and conforms to industrial standards for scientific and engineering use. It is available with an outer diameter ranging from 1.0 mm to 5.0 mm and an inner diameter from 0.5 mm to 4.0 mm, allowing wall thicknesses between 0.25 mm and 2.5 mm. Lengths can be ordered between 1 mm and 100 mm, making the product suitable for compact assemblies. The tube is manufactured from Pyrex 33 glass, which provides recognised thermal resistance and chemical durability.
Pyrex 33 is a borosilicate composition widely accepted in laboratory environments for its low thermal expansion and resistance to alkaline solutions. Typical wall‑thickness tolerance is ±0.05 mm, and surface finish is specified to 0.2 µm roughness, matching standard optical‑component requirements. The material’s clarity exceeds 90 % transmission in the visible spectrum, a standard metric for precision optics. Suppliers often pair the tube with silicone or PTFE seals to maintain hermetic integrity.
Typical buyers include pharmaceutical manufacturers, optical‑system integrators, and research laboratories that need reliable isolation components. The product can be shipped FOB or CIF from Shenzhen ports, and the supplier states flexible minimum order quantities and custom packaging on request. Importers should confirm the exact dimensions and packaging details before placing an order to align with their supply‑chain schedule. Payment terms are negotiable, and buyers are advised to request a mill‑test report confirming material composition.

Sourcing Glass tube from Shenzhen Solarvalley Scitech Development Co., Ltd. - China Import Guide
Before placing an order, importers should verify the glass‑tube dimensions, material grade and any required certifications directly with Shenzhen Solarvalley. Request a mill‑test report or material certification to ensure the Pyrex 33 composition meets your project specifications. Clarify the intended packaging format and confirm whether any special handling is needed for fragile items.
Logistics for this product are typically arranged under FOB or CIF terms from the Shenzhen port. The supplier does not publish lead‑time figures, so buyers need to ask for an estimated production and shipping schedule. Payment methods are negotiable; common options include L/C and T/T, but the exact terms should be agreed in advance.
Quality assurance commonly includes visual inspection for cracks, dimensional verification with calipers, and verification of material composition by spectroscopic analysis. Importers are advised to arrange a third‑party inspection before loading if large volumes are ordered. Ensure that all required import documentation, such as a Certificate of Origin and test reports, are obtained from the supplier prior to shipment.
