5 advantages and precautions for the use of video melting point instrument

The video melting point meter integrates video technology into the melting point measurement, which not only provides users with stable and reliable melting point test, but also intuitively displays the temperature curve and real-time video image to achieve playback, storage, video recording and other functions
.

It can observe the color change and decomposition temperature through video, and is a testing equipment for the food, pharmaceutical and chemical industries, which is used to detect the melting point
of organic crystalline substances such as drugs, reagents, spices, and dyes.

The 5 advantages of the video melting point instrument: 1, the large LCD touch screen The interface is clear and easy to understand, and the operation is simple
.

The capacitive touch screen is sensitive and closer to people's operating habits
.

A built-in 2-5 megapixel HD camera captures a video
of the melting process of the sample in real time.

2, can be measured at the same time four samples video melting point instrument once heated can place up to four samples, compared with the traditional single-well detection, the work efficiency increased by four times, four sets of data are recorded separately, traceable historical data, to ensure the reliability
of the report.

3, automatic measurement through the use of video imaging technology, high-resolution CCD detection and dynamic signal analysis, to solve the traditional automatic melting point instrument can not detect dark samples (only 450/470/490 have) shortcomings
.

4.
Multi-user and multi-permission hierarchical management Built-in user management function, you can freely add or delete user accounts, and can require different operating permissions
for each user account.

5, rich data storage and export methods Video melting point instrument provides up to 128G of massive space, can store atlases, test data, experimental videos, experimental methods and other details, and can realize laser printing, thermal printing, U disk export and other export methods, through the instrument rear interface for network cloud export
.

Precautions for the use of video melting point instrument: melting point determination is the basic means of identifying the nature of substances, and it is also one of the important methods of
purity determination.

Therefore, the melting point tester has an important position in the chemical industry and pharmaceutical research, and is an indispensable instrument
for the production of drugs, spices, dyes and other organic crystal substances.

The problems it pays attention to can improve the service life
of the instrument.

1.
The sample must be baked as required, crushed in a dry and clean mill, and the sample must be filled with free fall to tap the capillary, the filling height should be consistent, and the specific requirements should comply with the provisions of
the Pharmacopoeia.

2.
When inserting and removing the capillary, care must be taken to avoid breakage
.

3.
The linear heating rate is different, and the greenhouse results are inconsistent, and it is required to specify a certain specification
.

4.
It is advisable to fill five capillaries at a time for the measured sample, and take the average of the middle three readings as the measurement result after the determination respectively to eliminate the accidental error
caused by the capillary tube and sample preparation filling.

5.
Before the capillary is inserted into the instrument, a soft cloth should be applied to remove the contaminated substances on the outside to avoid staining
the oil bath.

6.
If you need to replace the oil bath tubing, follow the method described in the preparation before
use.
