Why the Capillary Tube need internal surface finishing?
Microsampling is very very important in in vitro diagnosis, especially in Mass Spectrometer, Gas Chromatograph, High Performance Liquid Chromatography, Biochemistry Analyzer, Electrolyte analyzer, DNA/RNA Analyzer, etc. If surface roughness is too high, the detection results will be easy inaccurate. In other special industrial sector, such as: hollow fiber membrane for hemodialysis dialyzer, the super surface finishing is a critial factor in manufacturing process.
High precision requirement
Reduce CV%
Injection volume consistency
Automation requirement
