When Configuring Fluidics For An Oligo Synthesis Instrument

  1. How small can you make your fluidic pathways?
  2. We commonly precision manufacture internal diameters of our components, including valves and manifolds, to 500μm ±125μm (0.020” ±0.005”). Should you need smaller channel IDs we are happy to work with you on your custom needs.

  3. What is the advantage of using IDEX Health & Science versus obtaining separate materials and assembling them myself or at a Contract Manufacturer?
  4. Accurate tolerancing of all components along the fluidic path is critical to a robust, reproducible instrument design. At IDEX Health & Science we not only work with you to design a robust fluidic subsystem, we can also simulate your design to mitigate potential fluidic issues prior to embarking on costly and time sensitive manufacturing. We work with you to identify and correct problems before they arise, saving you valuable time in your early stages. Additionally, an integrated subsystem from IDEX helps you consolidate the number of SKUs you have to manage.

  5. Do your solutions include a PCB?
  6. Our valve and pump products can include a PCB. We also offer our complimentary access to our Python Library for easy startup of your breadboard solution.

  7. Do your fluidics work in positive (push through) or negative (pull through) mode?
  8. Our fluidics can be adapted for either case and what is best suited for your synthesis needs.

  9. What functional testing is available to ensure instrument performance?
  10. IDEX offers a range of testing to provide our customers confidence in their fluidic architecture. Typical testing includes pressure decay to guarantee leak free components and subsystems, flow occlusion to test for passage blockages, system pressure to ensure the fluidics function, as well as fluid volumes as specified per your application.

  11. What materials are available for manifolds & pumps?
  12. For complex bonded manifolds, IDEX typically utilizes PMMA (Acrylic) and PEI (Ultem 1000). PMMA is recommended for systems with inert reagents; PEI is better suited for applications utilizing more aggressive reagents (i.e. solvents). IDEX can offer a wide variety of polymers (e.g., PEEK, PVC) for simple, cross drilled manifolds. The same holds true for pumps; PEI is more inert, though other materials such as acrylic or PVC present cost benefits.

  13. Are there any concerns I should have outside of lifetime for my pumps?
  14. Lifetime is critical in managing the cost and servicing of your instrument, however there are other key aspects to consider. When dispensing precious reagents, precision and accuracy can make or break the cost of your assay. Every pump manufactured at IDEX is functionally tested to guarantee precision and accuracy and confirmed to perform as intended.
