Description
The RO and DI Lab System SCSJ-20D is a compact laboratory water purifier that combines reverse osmosis with deionisation to produce around 20 litres per hour of high-purity water. RO removes the bulk of dissolved salts, organics and microorganisms, and the DI stage polishes the water to very low conductivity. A built-in meter displays water quality so users can confirm purity before each use.
Applications
- General laboratory analysis and reagent preparation
- Hospital and clinic laboratories
- University and school science labs
- Food, cosmetic and pharmaceutical QC labs
- Feed water for autoclaves, glassware washers and analysers

Typical system design
- Sediment and carbon pre-treatment
- RO membrane stage
- Mixed-bed DI polishing cartridge
- Optional UV and final filter (model dependent)
- Conductivity / resistivity monitoring

Why choose an on-site lab system?
Buying distilled or deionised water in containers is costly and quality can vary. An RO and DI Lab System produces fresh water on demand with traceable quality. Our team installs, commissions and trains your staff, and supplies replacement cartridges. See our laboratory systems range and DI resin. For background, see Wikipedia.
Frequently asked questions
Is this Type I ultrapure water? Typical configurations deliver Type II–III; Type I needs additional polishing.
Do you offer AMC for lab systems? Yes, including cartridge changes and calibration checks.
