Analytical instrument accuracy heavily depends on fluid delivery system integrity. We supply precision-polished tubing and valves with internal surface roughness controlled to Ra ≤ 0.4μm. Special sealing materials guarantee zero contamination and zero permeation. 

100% helium mass spectrometry leak testing ensures leak rates at the 1×10⁻¹¹ mbar·L/s level, providing an ultra-high purity fluid transfer environment for analytical instruments.
