Source Analytical Lab Chemical Suppliers

I need a reliable list of online suppliers based in India and Nepal who specialize in laboratory and research chemicals—specifically analytical standards and other testing reagents. My goal is to identify vendors that can ship promptly, share clear documentation on purity, and support repeat orders when needed.

Here is what I expect as a final hand-off:
• A spreadsheet (Excel or Google Sheets) with each supplier’s name, website, key product lines, pricing for common analytical standards, available pack sizes, and current stock status.
• Direct contact details (email and phone) of a sales or technical representative for faster communication.
• Notes on shipping terms, payment methods, and any minimum order requirements.
• A quick summary highlighting your top three recommendations and why they stand out (e.g., wider catalogue, faster delivery, stronger quality assurance).

Please rely on publicly available data, verify information wherever possible, and cite your sources or include screenshots of correspondence so I can validate everything easily.
