Source
Regional municipal supply pre-screened for inlet conductivity, hardness, and TOC. Source water is tested daily and logged before any production run begins.
Our story
Built for the bench teams who can't afford water that fails.
ResearchWater exists for the lab managers, principal investigators, and process chemists who treat solvent water as a reagent — not a consumable. Every SKU we ship is third-party tested per lot, USP-aligned, and traceable to the vial.
Why we exist
There's a gap in the research-water market — and we're filling it.
Most biotech and peptide research teams sit between two bad options. On one side, in-house Milli-Q systems that work fine while consumables are fresh — but produce drift as cartridges age, and demand validation overhead nobody on the bench wants to own. On the other side, the giant catalog suppliers — competent but slow, with minimum order quantities, complex account setup, and price sheets calibrated for institutional purchasing.
What's been missing is a mid-market option: a focused supplier that does one thing — research-grade water — extremely well, ships fast, prices fairly, and treats the lot-level Certificate of Analysis as a first-class deliverable rather than an afterthought. That's the gap ResearchWater was built to fill.
We don't sell media, columns, plastics, or anything else. We sell water — bacteriostatic, sterile WFI, ultrapure Type I, HPLC-grade, and LC-MS grade — and we put the same operational rigor behind it that pharma manufacturing puts behind a finished product.
How we make it
Four steps from municipal source to sealed vial.
Purify
Multi-stage train: reverse osmosis, electrodeionization (EDI), 185 nm UV oxidation for TOC reduction, and 0.1 µm final filtration before fill.
Fill
Aseptic fill per USP <1231> into Type I borosilicate glass vials or HDPE bottles. Stoppered, crimped, and tamper-evident-sealed inline.
Test
Every lot is sent to an accredited third-party lab for sterility, identity, pH, endotoxin, and resistivity testing before release. Retention samples held on-site.
Quality controls
Every lot has to pass these four gates.
Sterility USP <71>
14-day membrane filtration sterility test against fluid thioglycollate and soybean-casein digest media. Pass required for release.
Identity & potency
For preserved SKUs, benzyl alcohol identity and concentration verified by GC. Confirms the bacteriostatic system is intact at fill.
pH & resistivity
NIST-traceable calibration. ASTM D1193 Type I water tested at 18.2 MΩ·cm minimum at 25 °C; pH within published spec for each SKU.
Endotoxin LAL
Kinetic chromogenic LAL per USP <85>. Specification < 0.5 EU/mL for sterile aqueous SKUs; results documented per lot on the CofA.
Where we ship from
USA-based, FDA-registered, fast.
Production and distribution run out of a single FDA-registered, ISO 9001-certified facility in the United States. We hold inventory of every active SKU, which means most orders placed before 2 p.m. ET ship the same business day with tracking. No drop-shippers, no third-party warehouses, no surprise back-orders.
