Water is the most-used reagent in any laboratory. Ions, organics (TOC), particles, bacteria and endotoxins in poorly purified water show up as ghost peaks in HPLC, high blanks in ICP-MS and AAS, failed cell cultures and out-of-spec results that are hard to trace back. A dedicated laboratory water purification system gives every analyst water of the same, documented quality, on demand, without buying bottled HPLC water or keeping an old distillation still running.
Lab water is graded by resistivity (or conductivity), total organic carbon (TOC) and microbial content. Standards such as ASTM D1193, ISO 3696 and CLSI define the grades, and USP <1231> gives the pharmacopoeial guidance on water for pharmaceutical use.
| Grade | Typical quality | Common applications |
|---|---|---|
| Type 1 — Ultrapure | 18.2 MΩ·cm resistivity, very low TOC (ppb), <0.1 CFU/mL bacteria; endotoxin-free options | HPLC / UHPLC, LC-MS, ICP-MS, AAS, ion chromatography, cell & tissue culture, PCR and molecular biology |
| Type 2 — Pure / analytical | >1 MΩ·cm (<1 µS/cm conductivity) | Buffer and media preparation, reagent make-up, wet chemistry, clinical analysers, feed to a Type 1 polisher |
| Type 3 — RO / general | Reverse-osmosis grade water | Glassware rinsing, autoclave and humidifier feed, water baths, environmental chambers |
Most labs need two grades: Type 2 or Type 3 water in volume, plus a smaller amount of Type 1 water at the point of use. The Vivagen EXL7 range covers both from one compact system. Not sure which grade your methods need? Send us your SOPs or instrument list and we'll recommend a configuration.
The Vivagen EXL7 series (EXL7 Analysis, EXL7 Pure Plus, EXL7 Pure) delivers Type 1 ultrapure and Type 2/3 purified water from potable tap water in a compact benchtop or wall-mounted footprint. Typical Type 1 output is 18.2 MΩ·cm with TOC < 5 ppb, bacteria < 0.1 CFU/mL and endotoxin < 0.001 EU/mL. That is the purity labs usually get from Milli-Q®-class systems, at a lower cost of ownership and with consumables stocked locally in Mumbai.
It is a point-of-use system that turns potable tap water into purified lab water (Type 1, Type 2 or Type 3) through pre-filtration, reverse osmosis, deionisation, UV oxidation and final filtration. It replaces distillation units and bottled HPLC water with consistent, monitored water on demand.
Type 1 (ultrapure) water has 18.2 MΩ·cm resistivity and very low TOC. It is used for HPLC, LC-MS, ICP-MS and cell culture. Type 2 water (>1 MΩ·cm) is used for buffers, reagents and analysers. Type 3 is RO-grade water for glassware rinsing, autoclaves and water baths.
HPLC and LC-MS need Type 1 ultrapure water: 18.2 MΩ·cm, low TOC (ideally < 5 ppb) and 0.2 µm filtered. The Vivagen EXL7 Analysis configuration is designed for this.
Yes. Vivagen EXL7 systems deliver Type 1 water to the same specifications labs expect from Milli-Q®-class systems (18.2 MΩ·cm, ppb-level TOC, low bacteria and endotoxin), usually at a lower purchase and consumable cost. Milli-Q is a trademark of Merck KGaA.
Price depends on the water grades you need (Type 1, 2 and/or 3), daily volume and flow rate, feed-water quality, and options such as a storage tank, UV/TOC monitoring or ultrafiltration. Share your requirement and we will send a configured quotation within one business day.
Yes. Saksham installs and qualifies Vivagen systems, offers annual maintenance contracts, and stocks cartridges, RO membranes, UV lamps and final filters in Mumbai for quick replacement anywhere in India.
Yes. Vivagen EXL7 systems are designed to run on potable tap water. If your feed water has very high TDS or hardness, we will recommend a pre-treatment stage during the site survey.
No. Laboratory systems are for QC, R&D and analytical use. Production-scale Purified Water and WFI per IP/USP/EP need a validated plant-scale generation and distribution system. We can advise on the lab side of your water testing programme.
