With these 90° stainless steel bent connectors, connect your tubing to your PDMS microfluidic chips while keeping clear the area above your chip. This is particularly useful when using a microscope, for often tubing can obstruct the field of view.
Reusable and easily installable.

Make a reliable connection between a PDMS chip and soft-walled tubing, and tidy up your microscope stage with these stainless steel connectors. This coupler is bent at 90° so that it clears the space between your PDMS chip and the bottom of the condenser lens of your microscope.

  • Material: 304 stainless steel
  • Autoclavable, reusable
  • Recommended use: tubing to chip connections with silicone or Tygon tubing (see the table below for tubing ID correspondence)
  • Suitable for punched holes in PDMS chips
  • Length: 20 mm, 90° bent at 10 mm
  • Blunt tip (90° cut)
  • Leaves the observation area of your chip clear of any tubing, for a better illumination field under the microscope

Choose between packs of 20 or 100 units of stainless steel couplers, length of 20 mm and 90° bent at 10 mm each.

These fitted stainless steel fluidic couplers are used to connect your soft-walled tubing to your PDMS device, according to the following table:

Tips:

  • Always choose the coupler size with the closest OD above your soft-walled tubing ID.
