How to choose a constant temperature metal bath?

A constant temperature thermostat dry bath, also known as a dry bath, is a device controlled by a microcomputer that replaces traditional water bath equipment. It has less temperature fluctuation than traditional thermostats, avoids the pollution caused by traditional water bath heating, and provides more precise temperature control and a wider temperature control range. It is a good substitute for traditional water bath equipment.

A constant temperature thermostat dry bath is composed of modules and a main unit, and is generally divided into different models based on the types of modules, their quantity, and their temperature control range. Thermostat dry baths can be heating-only or heating and cooling. They use advanced microcomputer control and electric film technology, and have unique temperature control technology that provides high accuracy and stability. They come with different sizes of metal modules to fit various standard test tubes, and the modules are easy to replace. Generally, the difference between the same type of module from different manufacturers is not significant, and the main difference lies in the main unit of the dry bath.

First, it is necessary to determine the type of thermostat dry bath. Generally, the main unit of the thermostat dry bath is divided into heating, heating and cooling, and heating, cooling, and oscillating types. The selection can be based on the purpose of the experiment; the heating type is relatively cheaper, the heating and cooling type is more expensive, and the heating, cooling, and oscillating type is the most expensive as it has the most comprehensive functions.

Second, choose the control temperature range of the dry bath main unit. The control temperature range usually has two types: -10-100�� and -10-150��. The former is more common, while the latter is less common. When purchasing, you can choose according to the specific application situation. The -10-150�� control temperature range is larger and more expensive, but for general experiments that do not require such a high temperature, there is no need to choose this type.

Finally, choose the module specifications. The most common are 0.5ml, 1.5ml, and 0.2ml. The processing volume should be selected according to the content and requirements of the experiment. In addition, the temperature stability is the uniformity of the temperature of each part of the module when heated, which refers to the maximum temperature difference between each part, generally between 0.1-0.5��, the lower the better. If the temperature requirements of the experiment are not too strict, 0.5ml can be selected, and the lower the accuracy, the higher the price. The highest temperature is the maximum temperature that the instrument can reach, which is related to the control temperature range and is generally 5 to 10�� higher than the control temperature range.
