Learn how to choose a Lepto thermostatic circulator in one article

internal application

First determine whether it is an internal application or an external application. Internal application refers to the test that the sample is placed in the bath for constant temperature, heating or cooling; external application refers to the application of cooling, heating or constant temperature of the external device, the external device may be Closed or open.

For internal applications, it is necessary to clarify the requirements of the sample, such as temperature range, sample type, sample weight and immersion depth, whether gradient temperature changes are required, whether it is required to reduce the temperature within a specified time or how much the temperature is raised, etc., according to the requirements of the sample. Determine the constant temperature The requirements of the circulator are mainly the following:

temperature range

temperature stability

Program control function, the test of some samples requires a temperature gradient change requirement during the test process, which requires the equipment to have a program control function. For program control applications, it is also necessary to consider whether the heating power and cooling power meet the requirements of sample heating and cooling. Require

Slope control function: For the test of how much the temperature needs to be lowered or how much the temperature needs to be raised within the specified time, the equipment needs to have the slope control function. For slope control applications, it is also necessary to consider the heating power and whether the cooling power meets the requirements for sample heating and cooling

Bath opening size: it is the key to ensure whether the user's sample can be put down

Bath depth: ensure that the sample volume in the test container used by the user can be fully immersed

Magnetic stirring: During sample testing and reaction, is it necessary for the equipment to provide a stirring function to achieve stirring of the sample?

Sink cover: According to the user's observation of the sample, confirm whether the cover is transparent, whether it is required to be arched, whether it needs to be changed in size during application, etc.

Vertical/horizontal: Horizontal machine is suitable for placing on the table, vertical is suitable for placing on the ground

Accessories: brackets, test tube racks, sensors, bath fluids, bath covers, adapters, etc. required during sample testing

external application

For external applications, the temperature control system needs to be connected to the application end through pipelines, typically such as jacketed reactors, etc. For such external applications, the following factors should be considered:

the nature of the material

temperature range

temperature stability

Distance between temperature control system and external application

Cycle Pressure Requirements

Circulation Flow Requirements

Heating Power: Determines the rate at which the external application heats up

Cooling power: Determines the rate at which the external application cools down

Whether external temperature control is required: accurate material temperature control is very necessary for users

Connection interface/pipeline specifications: ensure smooth installation

remote control

body wash
