Product Overview
Labotemp Ultrapure Water Purification System LWS-02 provides Type I ultrapure water with resistivity up to 18.25 MΩ·cm @25°C for demanding laboratory applications such as DNA/RNA analysis, endotoxin testing, cell culture preparation, electrophoresis and sensitive instrumental assays. The integrated RO and ultrapure polishing stages reduce heavy metals, organic contaminants and microorganisms, delivering very low TOC, RNase/DNase and pyrogen levels. The compact bench-top design supports continuous production and on-demand dispensing while operating efficiently from municipal tap water (TDS < 300 ppm). The system is intended for analytical laboratories, research institutes, pharmaceutical and biotech environments where water quality affects accuracy and reproducibility.

Key Benefits

• Produces Type I ultrapure water up to 18.25 MΩ·cm for critical analytical workflows.
• Very low TOC (< 3 ppb) and ultra-low microbial/enzymatic contaminants (RNase/DNase).
• Integrated RO + ultrapure polishing for consistent, repeatable water quality.
• Instant dispensing 1.5–2.0 L/min (tank full) and continuous production 20 L/h.
• Compact bench-top footprint compatible with standard urban tap water input.

Features

• DNA-grade water quality and controlled endotoxin levels.
• Organic matter rejection > 99% (MW > 200 Da); ion rejection > 98% with new RO membrane.
• Particle and bacteria removal > 99%; bacteria < 0.01 cfu/ml; particles (>0.2 μm) < 1/ml.
• Typical TOC < 3 ppb; heavy metals < 0.1 ppb.
• Instant dispense up to 2.0 L/min; continuous output 20 L/h.
