Laboratory Water Grades According to ASTM D1193
ASTM D1193 defines different water purity levels. Type 2 water provides high-quality performance suitable for most routine laboratory applications.
| Water Grade | Typical Applications | Minimum Resistivity |
|---|---|---|
| Type 1 | HPLC, LC-MS, ICP-MS, molecular biology | 18 MΩ·cm |
| Type 2 | Reagent preparation, microbiology, general lab analysis | 1.0 MΩ·cm |
| Type 3 | Rinsing, feed water for Type 1 systems | 4.0 MΩ·cm |
Key Type 2 Parameters
| Parameter | Type II |
|---|---|
| Resistivity | ≥ 1.0 MΩ·cm |
| Conductivity | ≤ 1.0 µS/cm |
| TOC | ≤ 50 µg/L |
| Sodium | ≤ 5 µg/L |
| Chloride | ≤ 5 µg/L |
Conclusion: Type 2 water provides an optimal balance between purity, cost efficiency and versatility for routine laboratory work.
What is Type 2 Pure Water?
Type 2 water is high-quality laboratory water produced through reverse osmosis (RO) combined with deionization or electrodeionization (EDI), filtration and optional UV treatment. It is suitable for most daily laboratory applications that do not require the extreme purity of Type 1 water.
Typical Applications
- Preparation of reagents and buffers
- Microbiological media preparation
- Electrochemistry
- General spectrophotometry (UV-Vis)
- Feed water for Type 1 ultrapure water systems
Why Choose Type 2 Instead of Type 1?
While Type 1 is required for highly sensitive analytical techniques, Type 2 water is sufficient for the majority of laboratory procedures. It reduces operational costs while maintaining reliable and reproducible results.
Purification Technologies
- Reverse Osmosis (RO)
- Ion exchange cartridges
- Electrodeionization (EDI)
- UV disinfection
- Final filtration
Integration Options
Type 2 systems can operate as standalone bench units or as part of a central laboratory water system with storage tanks and distribution loops.
Related Laboratory Equipment
Type 2 water is commonly used to support laboratory glassware washers (page coming soon) and constant climate chambers, preventing mineral deposits and maintaining equipment reliability.
Laboratory Solutions Across the BeNeLux
Universities, hospitals and industrial laboratories in Belgium, the Netherlands and Luxembourg rely on Type 2 systems for stable daily operation and efficient laboratory workflows.
