Application field and function analysis of thermostatic metal bath

Thermostat dry bath, also known as dry bath incubator, is commonly used in molecular biology experiments such as enzyme digestion, protein denaturation, agarose gel melting, pre-PCR nucleic acid amplification detection, as well as sample preservation, serum quick separation, and coagulation in other experiments. It eliminates the risk of water accidentally entering reaction tubes and affecting experiments, and avoids the contamination issues associated with traditional water baths. In addition, it offers more precise temperature control and a wider temperature range. It overcomes the temperature fluctuation, contamination, and control difficulties of traditional dry bath incubators, and is a good substitute for traditional water bath devices.

The dry bath incubator consists of modules and a main unit, and is categorized by the type, temperature control range, and quantity of modules.

The characteristics of the Thermostat dry bath include: easy to maintain a constant temperature at multiple points, more efficient than water baths, temperature control through microcomputer digital display, heating using thermoelectric film technology, simultaneous display of set and real-time temperatures, temperature alert function, use of metal constant temperature blocks to prevent sample contamination caused by water baths, and the metal module is suitable for various sizes of sample tubes and equipped with an over-temperature protection device for more reliable use.

The main difference of the Thermostat dry bath lies in the host. The parameters of the host include the temperature control range, heating time, temperature stability, module temperature uniformity, display accuracy, maximum time setting, and maximum temperature. Among them, the maximum time setting, display accuracy, heating time, and temperature stability are the most important.

As for the temperature control range, there are usually two types: 0-100�� and 0-150��, with 0-100�� being the most commonly used and 0-150�� being less common. The specific range can be selected based on the specific situation, as most experiments do not require such high temperatures. Module temperature stability refers to the temperature uniformity of various parts of the module during heating, or the maximum temperature difference between different parts, which is generally between 0.1-0.5��, with lower values being better. A temperature stability of 0.5�� is sufficient for experiments with less stringent temperature requirements. The maximum temperature that the instrument can reach is usually 5-10�� higher than the temperature control range.
