We make the bench tools bilayer work depends on
Planar Membranes designs and manufactures bilayer cups and chambers for lipid bilayer and single-channel research. We focus on a tight, well-made product line rather than a sprawling catalog — cups and chambers in the styles, materials, and hole sizes researchers actually reach for.
Our equipment comes in both traditional and perfusion styles, in a variety of materials, and with four standard hole sizes. We also carry the accessories and replacement parts that keep that equipment working, so you can source it all in one place.
A few things we care about
Consistent & repeatable
Standard hole sizes of 100, 150, 200, and 250 µm — with each cup's hole size etched into its base so you always know what you're holding.
The right material
Cups in Delrin, polystyrene, or polysulfone, and chambers in black Delrin with a polycarbonate window — designed for both left- and right-handed operation.
Always happy to help
We're a small team that knows this equipment well. Reach out with your bilayer needs and questions — we like solving the hard-to-find problems.
