“The passion for science”
We are committed to providing reliable, durable water systems that optimize operating costs.
The Critical Role of Pure Water in Labs
Water constitutes 70–99% of the components in most biochemical, analytical, and cell culture reactions. However, common tap water contains various contaminants that can skew experimental results, be toxic to cells, or damage expensive equipment.
Contaminant Type | Examples | Impact on Experiment |
Inorganic Ions | Na⁺, Ca²⁺, Mg²⁺, Cl⁻ | Interferes with ICP-MS/AAS signals; causes cell death; leads to scale formation in HPLC |
Organic Compounds (TOC) | Humic acid, phenol | Alters pH; inhibits enzymes; causes high baseline in HPLC/GC-MS |
Microorganisms | Bacteria, molds | Contaminates samples; damages cell cultures, PCR |
Particles & Colloids | Dust, silica, suspended residue | Clogs chromatography columns; blurs UV-Vis spectra |
Endotoxin / RNase | Pyrogen, RNA-degrading enzymes | Causes cell shock; degrades RNA in qPCR, sequencing |
Laboratory Water Purification Process and Quality Standards
The purification process starts from raw water and progresses through multiple stages to achieve high purity. Quality parameters increase progressively, moving from high conductivity in raw water to high resistivity in ultra-pure water, ensuring suitability for sensitive experiments.
Stage | Resistivity (MΩ.cm) | Conductivity (µS/cm) | TOC (ppb) |
RO Water | ~0.05–0.2 | < 20 | < 50 |
Purified Water | 10–15 | < 0.1 | < 30 |
Ultra-Purified Water | > 18.2 | < 0.056 | < 5 |
International Standards for Laboratory Water Selection
Based on practical applications and the ASTM D1193-91 standard , laboratory water is categorized into four main grades:
The selection of the required water type depends on the specific application. Innova offers suitable product series to optimize both performance and cost efficiency for customers
Water Type | Main Application | Key Standard (ASTM) | Suggested Series |
Type III | Rinsing glassware, preparing basic solutions. | Conductivity < 4.0 uS/cm TOC <200 ppb | Nova C300/500 Classic C300/500 |
Type II | Cell culture, HPLC, ICP, ion analysis. | Resistivity > 1.0 MΩ.cm TOC <5 ppb Bacteria <10 CFU/ml | Nova EU10/15/20 Performa E10/15/20 Classic D15/20/25 |
Type I | Sensitive HPLC, GC-MS, DNA sequencing, sensitive molecular experiments. | Resistivity > 18 MΩ.cm TOC < 10 ppb Bacteria < 1 CFU/ml Endotoxin < 0.03 EU/ml | Nova U Nova Zero-Ion Performa U |
Understanding the required water type and purification process is the essential first step to ensuring accurate, reliable, and cost-effective experimental results.
