SINA GLASS

SINA GLASS has been operating since 1973, which shows long-term experience in the lab glassware market — a key factor for buyers needing reliable, consistent quality. Their key products like laboratory bottles, reactors, and quartz tubes are essential in chemical and pharmaceutical research, making them a trusted name in specialized industrial supply chains. However, none of their contact details or business documents are verified, which raises red flags for buyers concerned about legitimacy or communication reliability. Without verified work email, phone, or documents, it's hard to confirm their real location or operational status. Buyers should request additional proof before placing large orders or sharing sensitive technical requirements. This lack of verification is common among older suppliers who may not have updated their digital presence. For safety and trust, it's wise to cross-check with third-party sources or ask for a company profile or factory visit confirmation before engaging.
