    Small Low-Temperature Circulating Pump

    Overview Products Knowledge Standards Terms
    A small low-temperature circulation pump generates low temperatures through a compressor or thermoelectric cooling, and uses circulating fluid to transfer cold energy within a closed pipeline to maintain constant temperature cooling for experimental equipment. It is commonly used for temperature control in chemical reaction vessels and rotary evaporators to prevent sample overheating or crystallization.
    Selection
    When selecting, consider the target temperature range and accuracy, match the equipment interface size, and pay attention to the reservoir capacity and pump flow rate. Check the cooling power and adaptability to ambient temperature, as well as the corrosion resistance of metal components. Balance noise control and equipment size, and choose based on actual cooling needs.
