Temperature control solutions for biotechnology
Process thermostats
Unistats are designed to provide precise temperature control across a wide range of applications and industries. In the pharmaceutical sector, they are widely used in many departments, supporting processes from small-scale research through to large-scale production, with a temperature range spanning from -125 °C to 425 °C.
A key advantage of Unistats is their ability to rapidly adjust the temperature of the circulating heat transfer fluid (HTF). Combined with an advanced self-tuning PID controller, this allows for highly responsive and accurate temperature control throughout the process.
Baths and circulators
Huber’s portfolio of classically constructed open baths and circulators is divided into two categories. The KISS line consists of simple devices optimized for modest benchtop applications. They have a simple controller that is straightforward to use.
The CC range is equipped with the more advanced Pilot ONE controller and is well suited to smaller applications where the rapid response of Unistats may not be necessary. Offering temperature control from -90 °C to 300 °C, these systems serve as reliable and versatile laboratory workhorses for a wide variety of temperature control needs.
Chillers
Unichillers are specifically designed to remove heat from processes, although they can also provide temperature control within ± 0.1 K when fitted with an optional heater. The chiller range is divided into two main groups to suit different application needs.
The OLÉ range is intended for simpler applications, such as cooling condensers on low-volume rotary evaporators or supporting smaller bioreactors. These units feature a straightforward, easy-to-use controller that makes them well-suited to routine laboratory use.
The T range consists of floor-standing chillers designed for larger or more demanding applications. They are commonly used to cool condensers on high-volume rotary evaporators or to serve as a central chilled water supply for an entire laboratory.
In addition, they are frequently used to control the temperature of larger bioreactors where stable and reliable cooling is essential.
High precision temperature control in research, development
- Research & Development: Huber units offer consistent and predictable temperature regulation. This performance eliminates an unforeseen variation from the investigation
- Analytical laboratory: Analytical laboratories typically employ OLÉ chillers to cool sensitive instruments
- Scale up: Unistats are commonly used to regulate temperature in larger reactions due to their quick response
High precision temperature control in production
- Manufacturing: Batch sizes might range from "low" to "high"
- Formulation: Bench-top open bath systems and chillers are commonly employed in a variety of applications
- Bioproduction: Heater-equipped unichillers offer cost-effective and dependable temperature management for bioreactors ranging from 1-liter fermenters to 3,000-liter production scales
- Continuous flow: Unistats and open bath units are utilized to accurately control the temperature of reactor zones
- Quality control: Procedure intended to ensure that raw ingredients, purchased compounds, and final products meet specification
