Bulk & Custom Quotes

Larger quantities, alternate fill weights, and materials not listed in the public catalog are available by quote for verified institutional accounts. All materials are supplied for laboratory research use only — not for human or veterinary use.

When to request a custom quote

• Quantities beyond the largest listed vial size for a catalog item
• Non-standard fill weights for an ongoing study or protocol
• Recurring or scheduled orders for a lab's regular research use
• Materials referenced in our catalog by CAS number but not currently listed at your required quantity

What to include in your request

• Institution or business name and research affiliation
• Material name and CAS number
• Quantity or fill weight required
• Purchase order, if applicable
• Any timeline constraints for your protocol or study

What happens after you submit

Our orders team confirms material availability, issues a formal quote, and completes account verification if you don't already have a verified institutional account on file. Once verification and the research-use covenant are complete, the order is released for processing.

Payment terms

Bulk and custom orders are invoiced on account approval. We accept ACH/bank transfer, purchase orders from verified academic and commercial laboratory accounts, and check; additional payment options are available on request and are confirmed on the invoice. Terms are agreed at quotation — see institutional accounts for full detail.

Documentation

Bulk and custom orders ship with the same lot-specific Certificate of Analysis as standard catalog orders — see How to Read a CoA.

Request a quote

Submit your request through our existing institutional inquiry form, including the details above. If you don't yet have a verified institutional account, the same form starts that process — see our institutional accounts page for the verification requirements.
