Stainless Steel 90° Bent PDMS Couplers
- Product SKU: PN-BEN-16G-20
- Category: Microfluidic Accessories, Needles & Couplers
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
