Introduction to relevant materials
The sample bottle produced by MS technology in the United States is made of Schott neutral borosilicate glass tube. In the production process, the photoelectric device of the processing equipment detects the whole process to ensure that the processed sample bottle meets the physical characteristics.Product features: sample bottle
There are two kinds: transparent bottle and brown bottle.
The size of the bottle mouth is accurate to ensure that the automatic sample feeder can grasp accurately.
Product use:
Applicable to most of the autosamplers
The brown sample bottle is suitable for the preservation of all chemical samples in the laboratory.
Gasket selection guide;
The correct choice of the spacer for the sample cap can optimize the instrument performance and test results.
