Peter Huber Ministat 125w Refrigerated Heating Bath Circulator, Temperature Range: -25 to 150°C

The Peter Huber Ministat 125w is a highly efficient, water-cooled refrigerated heating bath circulator designed for laboratories where space is at a premium. As part of the world's smallest cooling circulator range, its compact dimensions allow it to be seamlessly integrated into fume hoods or small technical plants. This model is equipped with the advanced Pilot ONE multi-touch controller, featuring a 5.7" TFT color display that provides a smartphone-like interface with intuitive menu navigation and a technical glossary. Delivering a temperature range of -25 to 150°C with 1.0 kW of heating power, the Ministat 125w is engineered for rapid temperature changes and high precision. Its variable-speed pressure/suction pump is ideal for the thermoregulation of external closed systems like photometers and refractometers, while the water-cooled refrigeration system ensures consistent performance even in environments with high ambient temperatures.

Frequently Asked Questions

1. What are the advantages of the water-cooled "w" version?
The Ministat 125w uses water cooling to remove heat from the refrigeration system. This makes it ideal for use in small, enclosed areas like fume hoods because it does not exhaust hot air into the room and operates more efficiently in warm environments.

2. Can I use this unit for internal and external applications?
Yes. While its compact size is perfect for external closed systems such as refractometers and viscometers, the 2.75L bath opening also allows you to thermoregulate small objects directly inside the tank.

3. How does the Pilot ONE controller improve ease of use?
The Pilot ONE features a large 5.7" touchscreen with clear icons, a technical glossary, and smartphone-like navigation. It also includes "Plug & Play" technology, allowing the controller to be used as a remote control or easily swapped during service.

4. Is the pump pressure adjustable for delicate glassware?
Yes, the pump speed is infinitely adjustable. For additional protection, you can use the optional VPC (Variable Pressure Control) to monitor and limit the maximum pressure exerted on sensitive external glass apparatus.

5. What type of refrigerant does the Ministat 125w use?
This model uses R290 (Propane), a natural refrigerant that is environmentally friendly with zero Ozone Depletion Potential (ODP) and a very low Global Warming Potential (GWP).
