خزان الترموستات والحمام المائي هما نوعان من المعدات التجريبية المستخدمة لتوفير بيئة درجة حرارة ثابتة. They have some differences in working principles, use scenarios and temperature control methods.

Principle of operation
Thermostat tank: A thermostat tank is a device that maintains a constant temperature through electrical heating and temperature control systems. The thermostat tank usually has strong temperature stability and accuracy, and can provide a constant temperature environment in a narrow temperature range. It is suitable for experiments requiring high precision constant temperature, such as biology, الدواء, chemistry and other fields.

Water bath: A water bath is a simple heating device that heats water or other liquid to a set temperature through a heating element. The water bath is usually used to provide a constant temperature heating environment, but the temperature control accuracy is relatively low, which is suitable for some experiments that do not require very high accuracy.

Use Cases
Thermostat tank: Due to its high temperature stability and accuracy, thermostat tank is suitable for experiments requiring relatively strict constant temperature conditions, such as cell culture, PCR reaction, enzyme catalysis experiment, إلخ.

Water bath: Water bath is suitable for general experiments, such as heating reagents, sample dissolution, sample pretreatment, إلخ., but for experiments with high temperature requirements and accuracy, water bath may not be suitable enough.

وضع التحكم في درجة الحرارة
Thermostat tank: Thermostat tank usually adopts advanced PID control technology, which can achieve accurate temperature control and stability.

Water bath pot: The temperature control method of water bath pot is relatively simple, usually using mechanical or simple electronic temperature controller.

نطاق درجة حرارة
Thermostat tanks: Thermostat tanks can usually provide a wide range of temperatures, from lower temperatures (such as negative degrees Celsius) to higher temperatures (generally not exceeding 100 درجة مئوية).

Water bath: The temperature range of water bath is usually relatively limited, generally between 0 degrees Celsius and 100 درجة مئوية.

على العموم, the constant temperature tank is more suitable for experiments requiring high precision and high stability of constant temperature than the water bath, while the water bath is suitable for general constant temperature heating experiments. When choosing the appropriate equipment, the decision is made based on the experimental requirements and the required temperature accuracy.
