Polymicro Technologies now offers a new
line of thick walled capillary tubing with our proven, durable
polyimide coating.
This new line was
designed specifically to give the user added strength and improved
performance in packed capillary liquid chromatography columns, thereby
eliminating the need to employ thin walled gas chromatography tubing
as the column substrate. As with all Polymicro capillary products, it
can be used across a broad range of other applications and markets.
The initial product
offering includes four standard sizes, all with a common OD of 665µm.
ID's vary from 150µm up to 300µm. Production of custom sizes to meet
your exact product requirements are available upon request.
