Tubing & Components

The Lee Company’s Miniature Inert System of Tubing and Components, or MINSTAC®, is a family of flow connection and control products that enable fast and efficient design of systems to handle critical and challenging fluids. They mate quickly and easily with many of our solenoid valves and pumps to facilitate rapid setup.

The MINSTAC® family consists of a wide range of products, including:

  • Tubing and fitting ends
  • Adapters and unions
  • Check valves
  • Filters & safety screens

Each component is optimized for miniaturization and constructed out of inert materials.

062 MINSTAC® TUBING & FITTINGS

Off-the-shelf single and double-ended tubing assemblies improve your speed of development. The basis of the Lee 062 MINSTAC System is its unique collet-lock design which enables miniature, robust threaded connections for PTFE tubing.

  • Compatible with all 062 MINSTAC ports on a variety of valves (see VHS, Xover, LFY).
  • Chamfered PTFE fittings facilitate smooth liquid flow
  • Narrow tubing diameters (0.012″ ID, 0.032″ ID, or 0.04″ ID standards) reduce fluid volume
  • For use with 0.062″ (1.57 mm) OD PTFE tubing
  • Fitting end is 0.138-40 UNF
  • Self-aligning features provide a reliable leak-proof system
  • Customization available at volume

062 MINSTAC TUBING ASSEMBLIES

We offer two different styles of ¼-28 flat bottom (FB) tubing assemblies: low profile and standard. Both are available as single or double-ended assemblies to improve your speed of development. Customization available for volume applications.

  • Low Profile style features minimized fitting height above the installation boss and minimized axial spacing between bosses, enabling tighter-spaced connections.
  • Standard style features an anodized aluminum finish and machined tubing grips for easy hand-installation.

INERT CHECK VALVES

Our inert check valves, made of PEEK, FFKM and PTFE, offer simple threaded connections to ease system integration and provide backflow protection.

  • Cracking pressure: 4 inches of water (1.0 kPa)
  • Chemically inert materials: PEEK body, FFKM diaphragm, PTFE
  • Leakage: 10 μL/min at 28 inches of water in the checked direction
  • 35 microns (minimum) filtration recommended

INERT SAFETY SCREENS

Our inert safety screens are constructed without the aid of any chemical bonding materials, making them ideal for applications with fluids. They are designed to work in conjunction with a system filter and offer last chance protection of sensitive fluidic components such as valves, sensors, and flow cells.

  • Flow direction: bi-directional
  • Screen material: woven mesh
