Sartorius Arium™ Lab Water Systems: Type 1/2/3 Purification
109 productsSartorius’ arium™ line converts tap or pretreated water into the lab grades you actually use—Type 1 (ultrapure), Type 2 (pure), and Type 3 (RO)—with on-demand dispensing, closed storage options, and accessories that keep quality stable at the point of use. The range covers compact bench systems through modular setups for multi-point distribution.
What Is Lab Water Purification? (Type 1/2/3 Basics)
Instruments and biology are sensitive to more than just ions—organics, particles, microbes, and endotoxins also skew results. A lab water system removes these contaminants in stages (e.g., RO → polishing via ion exchange or EDI → UV for organic control → ultrafiltration and final 0.2 µm filtration), then monitors quality so you can trust every draw. For critical life-science work, pair Type 1 with an ultrafilter; for analytical methods like HPLC/ICP/LC-MS, UV is recommended to limit organics.
Water Grades Explained: Type 1, Type 2 & RO Water
Different tasks call for different grades. Use the quick map below to align your workflow to the water that fits.
| Grade | Typical Use | Treatment Emphasis | Notes |
|---|---|---|---|
| Type 1 (Ultrapure) | PCR/NGS, cell culture, HPLC/LC-MS/ICP-MS solvents & blanks | Polishing + UV/UF + final filter | For the most critical applications. |
| Type 2 (Pure) | Buffers/media prep, general analytical work, feed for Type 1 systems | RO + EDI/ion exchange | Can substitute where Type 3 is used; also feeds Type 1. |
| Type 3 (RO) | Glassware washers, initial prep, feed to Type 2/1 | Reverse osmosis | Lowest cost per liter; not for trace-level analytics. |
Arium™ Product Families & Core Technologies (RO, EDI, UV, UF)
The arium™ portfolio scales from small, single-bench needs to multi-point labs. Arium Mini meets up to ~10 L/day Type 1 demand in a compact footprint. Arium Comfort combines Type 1 + Type 2 (Comfort II) or Type 1 + Type 3 (Comfort I) from tap feed in one unit. Arium Pro is a modular Type 1 platform with options like UV and ultrafilter and is recommended for daily needs up to ~100 L, depending on feed quality. Remote Smart Station dispensers and Bagtank closed storage protect quality and let you draw water where you work.
Core tech, simplified
- RO to strip the bulk of dissolved salts and particles
- EDI / ion-exchange polishing for low ionic load and stable resistivity
- UV to reduce organic content (TOC) for sensitive analytics
- UF + final 0.2 µm to control endotoxins/microbes at the point of use
- Closed storage (Bagtank) to minimize recontamination between draws
Applications & Use Cases: Ultrapure, Pure and RO Water
Matching grade to task improves data quality and cost control. Type 1 supports nucleic-acid-sensitive and trace-level analytical work; Type 2 covers general prep and can feed Type 1; Type 3 handles washers and bulk prep. Sartorius’ guidance underscores UF with Type 1 for life-science workflows and UV for organic-sensitive analytics.
Common pairings
- Type 1 + UF: PCR/NGS, cell culture, enzymatic assays
- Type 1 + UV: HPLC/LC-MS/ICP workflows and low-TOC blanks
- Type 2: Buffer/media prep, general assays, Type 1 feed
- Type 3: Glassware washers, preliminary dilutions, Type 2 feed
How to Choose Your Lab Water System (Sizing & Compliance)
Start from your use-case, then size the system around demand and layout. Consider feedwater (tap vs pretreated), which grades you need at the bench, daily/peak liters, number/placement of dispense points, and any audit-trail or data-logging requirements. Finish by modeling operating cost (consumables, waste ratio) to avoid surprises over time. Sartorius’ buyer guides provide helpful checkpoints for this decision path.
Fast decision path
- Feedwater: Tap → pick RO-based combos; pretreated → consider Pro/Type 1 modules
- Grades: Type 1 only vs Type 1 + 2/3 in one chassis
- Demand: Average and peaks; storage or remote dispensing where needed
- Controls: UV, UF, TOC, data logging/audit trail
- TCO: Cartridge sets, UV lamps, UF/final filters, waste ratio
Typical configurations
- Single bench, analytics: Mini + UV, Smart Station at instrument
- Core lab, mixed use: Comfort II (Type 1+2) + Bagtank + Smart Station
- High-throughput Type 1: Pro with UV/UF + multiple Smart Stations

Installation & Maintenance Essentials
Before purchase, check space, power, inlet pressure/quality, and drain access. Plan a startup flush and routine sanitation cadence per the manual. Replace polishing packs, UV lamps, ultrafilters, and final 0.2 µm filters on schedule, and keep storage closed to avoid recontamination. Smart Station dispensers and Bagtank closed storage let you place outlets near instruments while maintaining quality at the point of use.
Lab Water FAQs: TOC, Endotoxin & Storage
Q1. What’s the practical difference between Type 1, Type 2, and Type 3 water?
Type 1 (ultrapure) is for the most sensitive work—PCR/NGS, HPLC/LC-MS/ICP-MS blanks and solvents. Type 2 (pure) suits buffer/media prep and general analytics and can feed Type 1 systems. Type 3 (RO) is for glassware washers, initial dilutions, and as feed to Type 2/1.
Q2. Can I produce Type 1 water directly from tap feed?
Yes—choose a combo lab water purification system that integrates RO plus polishing (e.g., arium™ Comfort variants). If your tap water is very hard or variable, plan for appropriate pre-treatment to protect cartridges and maintain resistivity.
Q3. How do I size production rate and storage for my lab?
Add up daily liters and identify peak draws (e.g., wash cycles or instrument startup). Pick a production rate that comfortably meets peaks, then buffer with closed storage (e.g., Bagtank) and place Smart Station dispensers near instruments to reduce carry distance and recontamination risk.
