· Water demineralisation
Ion Exchange Cartridges
Complete solutions for water demineralisation
A reliable way to produce demineralised water in medical practices, laboratories and industrial facilities. The equipment is split into two lines depending on the water volume required and is complemented by high-precision quality monitoring systems.
Key advantages
Two lines for different volumes
Synthetic cartridges for small volumes and stainless steel cartridges for medium and large ones.
Resin leakage protection
An innovative filtration system prevents any resin leakage and protects the connected equipment.
TKA / Thermo compatibility
The DS 450 replaces the TKA / Thermo DI 425 and the DS 750 replaces the TKA / Thermo DI 750.
Consistent water quality
Outlet conductivity of 0.1 – 20 µS/cm at a maximum water temperature of 30 °C.
Robust construction
Polyethylene housing for the synthetic line and AISI 316 stainless steel rated to 10 bar for the steel line.
Quality monitoring
Stakpure digital and analogue conductivity meters for online monitoring of pure and ultrapure water.
Synthetic cartridges — up to 10 litres per day
| Model | Type | Flow rate | Capacity | Replacement for |
|---|---|---|---|---|
| DS 450 | Disposable | 50 l/h | 425 l | TKA / Thermo DI 425 |
| DS 750 | Regenerable | 100 l/h | 750 l | TKA / Thermo DI 750 |

Conductivity meters
| Instrument | Type | Measuring range | Features |
|---|---|---|---|
| DC 400 | Digital | Conductivity 0.1 – 300 µS/cm, temperature 0.1 – 50 °C | A large graphic display with two-colour backlight: the green light turns red when readings leave the set range. Auto-calibration before every measurement, temperature compensation, versions with a potential-free contact and a solenoid valve |
| AC 100 | Analogue | 0.1 – 50 µS/cm | Connects directly to DS 1500 – 15000 series cartridges |
| AW 100 | Analogue | 0.1 – 50 µS/cm | Wall mounted |

Applications
Medical practices
Demineralised water for autoclaves and instrument processing at up to 10 litres per day.
Laboratories
Feeding pure water systems, glassware rinsing, preparation of solutions.
Industrial facilities
Volumes from 300 to 3,000 litres per hour for production tasks.
Service and maintenance
Regenerable cartridges reduce the cost of ownership at steady water consumption.
