Peter Huber Ministat 125 Cold Warmth Bath Circulator

The Peter Huber Ministat 125 is a masterclass in compact engineering, representing the smallest cooling circulator series in the world. Designed for precision thermoregulation from -25°C to +150°C, this unit is powerful enough to manage external closed systems like photometers, refractometers, and viscosimeters, yet compact enough to fit into tight laboratory extraction hoods. The Ministat 125 features the advanced Pilot ONE controller with a 5.7" TFT color touchscreen, providing a "Plug & Play" interface that is as intuitive as a smartphone. With its stainless steel construction and high-performance heating and cooling capabilities, the Ministat 125 delivers exceptionally rapid ramp rates and industry-leading temperature stability.

Key Features:

• Ultra-Compact Design: The world's smallest cooling circulator, optimized for space-sensitive laboratory environments without sacrificing thermal power.
• Pilot ONE Controller: Professional 5.7" touchscreen interface with multi-language support, integrated programmer, and "Easy Control" functionality for routine and complex tasks.
• Variable Pressure Control (VPC): Equipped with a powerful variable-speed pressure and suction pump. The VPC system allows for precise pressure management to protect delicate external glassware.
• Active Cooling Control: Features automatic cooling power regulation, enabling full cooling capacity at high working temperatures while saving energy during low-demand operation.
• Rapid Thermoregulation: The combination of a small internal bath volume and a high-power 1.0 kW heater results in exceptionally fast heating and cooling cycles.
• Unsupervised Operation: Complies with DIN 12876 Safety Class III (FL) standards, allowing for safe, continuous operation with flammable liquids even when unattended.
• Digital Connectivity: Fully equipped with Ethernet, USB (Host and Device), and RS232 interfaces for remote control, data logging, and laboratory automation.
• High-Quality Materials: All wetted parts are manufactured from high-grade stainless steel or premium polycarbonate to ensure chemical resistance and longevity.

The Ministat 125 is the definitive solution for laboratories that demand the highest levels of precision in the smallest possible footprint. Its ability to achieve rapid temperature changes while maintaining a stable thermal environment makes it an indispensable tool for modern analytical research.

Frequently Asked Questions

1. What are the typical applications for a unit this small?
The Ministat 125 is specifically designed for thermoregulating external closed systems where space is limited. Common uses include temperature control for refractometers, polarimeters, small jacketed reactors, and viscometers.

2. Can I reduce the bath volume even further?
Yes. Optional displacement inserts are available that can reduce the internal bath volume by approximately 50%. This further accelerates heating/cooling rates and reduces the amount of thermal fluid required.

3. How does the Variable Pressure Control (VPC) protect my equipment?
The VPC allows you to set a maximum pressure limit. If the pump pressure approaches this limit, the controller automatically reduces the pump speed, preventing your external glass apparatus from bursting.

4. Can the controller be removed for service?
Yes. The Pilot ONE controller uses "Plug & Play" technology. In the event of a service requirement, the controller can be easily swapped out or moved to another compatible Huber unit without needing to send the entire circulator for repair.

5. What is the maximum ambient temperature for operation?
The Ministat 125 is designed to operate reliably in laboratory environments with an ambient temperature up to 40°C.
