Product Range and Specialties of DanYang Sunny Glasswork Co.,Ltd
The catalogue covers several categories of laboratory vials: autosampler vials (2 ml, 20 ml), EPA‑type vials (40 ml), and amber HPLC vials (4 ml). In the analytical chemistry market, such vials are typically made from Type I borosilicate glass, conform to USP <659> for extractables, and are offered in clear or amber finishes to protect light‑sensitive samples. Volume tolerances are usually ±2 % of nominal, and thread standards such as 13‑425 are used for 4 ml and 2 ml vials, matching common autosampler specifications. The 9 mm PTFE/Silicone septa combine PTFE’s chemical inertness with silicone’s elasticity, meeting ASTM D1418 for polymer classification, and are supplied with polypropylene caps that meet ISO 9001 quality management criteria. Micro‑inserts of 250 µl are designed for low‑volume sampling and fit standard 4 ml vials, while 11 mm aluminium crimp caps are a standard closure for 13‑425 vials, providing a hermetic seal.
Trade and Export Information - DanYang Sunny Glasswork Co.,Ltd
China is a major exporter of laboratory glassware and polymer accessories, with HS chapter 70 covering glass products (e.g., HS 7010 for laboratory glassware) and HS chapter 39 covering PTFE components (e.g., HS 3911 for polymer septa). Typical destination markets include North America, the European Union, and Southeast Asian countries, where agricultural research labs and food‑testing facilities import such consumables. Buyers commonly require certifications such as ISO 9001, ISO 13485 for medical‑related use, and compliance with USP or EP standards for extractable limits. Export shipments are usually packed in cardboard cartons, stacked on wooden pallets, and transported in 20‑ft or 40‑ft containers under Incoterms CIF or FOB, with moisture‑resistant liners to protect glass integrity.
Sourcing from DanYang Sunny Glasswork Co.,Ltd - Buyer Guidance
When sourcing these vials, request a product specification sheet that details glass type, volume tolerance, wall thickness, and thread dimensions. Ask for certificates of compliance with USP <659> or EP 2.2.2, as well as any ISO quality‑system certificates the supplier holds. Verify that septa are supplied with PTFE and silicone layers as described, and request a material safety data sheet for the polymer components. Typical minimum order quantities for glass vials range from 10 000 to 50 000 pieces per SKU, with lead times of 3‑6 weeks after order confirmation, depending on container size and production scheduling. Confirm packaging details, such as the number of vials per inner box and outer carton dimensions, to ensure efficient loading and handling.
