Vacuum Heat Shrinking: The Gold Standard for Precision Bore Engineering

While standard redrawn tubing is sufficient for general lab use, mission-critical applications in UHV environments and laser technology require absolute geometric perfection. At NDS Technologies, we utilize a specialized Vacuum Heat Shrinking process. By heating borosilicate or quartz tubing and collapsing it over a high-precision titanium or stainless steel mandrel under vacuum, we achieve an internal diameter (ID) tolerance of ±.02%.

Introduction: Precision Bore

Our precision bore components are engineered for sectors where a failure of even one micron can lead to system-wide malfunction:

Medical Devices: Micron-level dosing units and flow restrictors for corrosive or highly volatile liquid delivery systems.

Aerospace & Defense: Glass-to-metal hermetic transitions for sensors and specialized vacuum feedthroughs.

Laser Technology: Precision bore quartz tubing for laser flow tubes, cooling jackets, and capillary spacers.

Analytical Instrumentation: High-accuracy glass cylinders for HPLC (High-Pressure Liquid Chromatography), capillary viscometry, and NMR tubes.
