What's the difference between bacteriostatic water and sterile water?

Both are sterile water for injection, USP. Bacteriostatic water adds 0.9% benzyl alcohol as a preservative, which inhibits bacterial growth so a vial can be entered more than once. Plain sterile water has no preservative and is intended for single use.

Can you really beat what I pay now?

Yes. Send us your current supplier's price for the same product and strength, along with your monthly quantity, and we quote under it. We'd rather earn the account on price and keep it on paperwork and consistency.

What do you carry besides bacteriostatic water?

Around 80 lyophilized research peptides plus acetic acid solution and phosphate-buffered saline, all sold by the 10-vial package. The full list is in the catalog on this page. If you need something we don't list, email us and we'll check availability.

Do you provide a certificate of analysis for every lot?

Yes. Bacteriostatic water ships with a certificate covering benzyl alcohol, pH, sterility, bacterial endotoxins and particulate matter. Peptide lots ship with their certificate as well, and you can ask for the current one before ordering.

Do you offer private label?

Yes, for qualifying contract volumes. Contact us with your expected monthly volume and we'll walk you through artwork, minimums and timing.

Do you sell to individuals?

No. We sell to business entities only: research-use-only companies and laboratories. We'll ask for your company details before opening an account.

How long is a vial good for once it's opened?

Once a vial has been entered, use it within 28 days. Sealed, unopened vials carry a 24-month shelf life from the date of manufacture.

What are your lead times?

Lead time depends on format, volume and whether you have a standing monthly account. We confirm it with your quote. Standing accounts get reserved capacity.

Bacteriostatic water: five tests, every lot.

The same five parameters appear on every bacteriostatic water certificate of analysis we send.

Benzyl alcohol
HPLC assay
Confirms preservative content against the 0.9% target.
pH
Potentiometric
Measured on every lot and reported on the certificate.
Sterility
USP <71>
Membrane filtration or direct inoculation sterility test.
Bacterial endotoxins
USP <85>, LAL
Limulus amebocyte lysate test for endotoxin levels.
Particulate matter
USP <788>
Sub-visible particle count by light obscuration.

A certificate of analysis with every lot.

Every shipment is matched to a lot number and its certificate. For bacteriostatic water that includes the pH report; for peptides, the lot's certificate is available on request before you order.

We beat any price: Send the invoice from your current supplier. Same product, same strength, we come back lower. That is the whole pitch.
Paperwork with every lot: A certificate of analysis and pH report travel with each lot, so your own documentation stays complete.
One fill source: Every vial comes from the same pharmacy fill line. No mixing of suppliers between orders.
Reserved capacity: Standing monthly accounts get capacity set aside, so supply doesn't depend on what's left.
Private label: Your brand on the label for qualifying contract volumes. Ask about artwork and minimums.

Supply, done properly.

RUO Source exists for one reason. Research labs and peptide companies are overpaying for the same vials, and they deserve a supplier that beats the price and still sends paperwork they can file.

Every vial we sell comes from a licensed U.S. pharmacy fill line, ships with its certificate of analysis, and is sold only to business entities. Pricing is set per account, and if you are already buying elsewhere, we start from your current price and go under it.
