Product Overview

Laboratory High and Low Temperature Circulating Bath

A laboratory high and low temperature circulating bath is a precision temperature control system that integrates heating, cooling, and circulation functions. It is primarily used to supply a temperature-controlled circulating fluid to laboratory equipment such as reaction vessels, rotary evaporators, and molecular distillation systems, enabling precise temperature regulation and efficient heat transfer.

Working Principle

The system combines a compressor-based refrigeration unit with an integrated heating system to achieve both cooling and heating. A PT100 temperature sensor continuously monitors the fluid temperature, while the control system maintains a temperature control accuracy of ±1°C. A circulation pump delivers the heat transfer fluid to external equipment at a flow rate of 40–42 L/min and a pump head of 6–28 m, creating a closed-loop temperature control system. Depending on the model, the operating temperature range can cover -80°C to 200°C.

Applications

Laboratory high and low temperature circulating baths are widely used in chemical synthesis, including low-temperature reactions and high-temperature reflux; pharmaceutical research and development, such as temperature-controlled crystallization; materials testing, including high- and low-temperature aging tests; new energy battery testing; and university research laboratories. Available bath capacities of 5–100 L can accommodate experimental requirements of different scales.

High and Low Temperature Circulating Bath Selection Guide

When selecting a laboratory high and low temperature circulating bath, consider the temperature range required for your application. Deep-cooling models operating from -30°C to -80°C are suitable for low-temperature reactions, while high-temperature operation up to 200°C is suitable for heating and reflux applications. Heating and cooling power, typically ranging from 4,000 to 20,000 W, affects the rate of temperature changes. Different refrigerants, such as R22, R404A, and R23, are used for different temperature ranges and system designs. It is also important to ensure that the circulation pump's flow rate and pump head are suitable for the external equipment and the flow resistance of its piping. Safety features such as overload protection and liquid-level alarms should also be considered.

Customer Photos/ Customer Review

The digital display temperature control is very accurate, with small temperature fluctuations and stable constant temperature effect. Several sets of data were tested and the data were basically consistent with no deviation and high accuracy. The laboratory needs such an instrument.

The packaging of the machine was very strong, and there was no bump when it was delivered to the laboratory. The LCD panel looks clear, the hot and cold switching operation is simple, the closed cycle operation is not very noisy, and the temperature control is relatively stable. It is just right for experiments with a reactor. Customer service is very patient in communicating parameters in the early stage and responds quickly to questions.

Already used it, overall very satisfied. One machine can handle heating and cooling, which saves a lot of trouble. It can be used for routine experiments or simple research and development. The price is well worth it.

It can heat and cool with one machine, which is very convenient and does not need to be equipped with other equipment. The numbers on the screen can be seen clearly, the temperature can be adjusted accurately, the temperature rises and falls quickly, and the temperature can be stabilized quickly. It is very convenient to control the temperature during daily experiments. It would be more convenient if there are 2 pieces of raw material belts.
