Capillary Polishing Station

Make near perfect glass capillary ends in the lab, to give optimal chromatographic response and robustness.

The Capillary Polishing Station, or CPS, allows you to easily make near perfect glass capillary ends in the lab, in order to give optimal chromatographic response and robustness.

Capillary Polishing Station 2

Introducing the new and improved Capillary Polishing Station 2 (CPS-2), from ESI Source Solutions. CPS-2 provides a simple means to make clean polished ends on various OD glass capillaries tubing and 1/16″ PEEK tubing. This is essential for reliable high-sensitivity capillary chromatography. The device consists of two parts, the polishing base and the capillary jig, shown below.

The new Capillary Polishing Station has three disks of lapping film: a 30 micron (um) aluminum oxide disk (green), a 15 um diamond disk (orange) and 1 um diamond disk (white), which are located in the approximate locations shown in the picture above. The CPS also includes guide sleeves for different OD glass capillary tubing, one for 360um and one for 280um tubing.

Imaging the ends of the glass capillaries is critical to the polishing process. Therefore, we highly recommend the use of our Digital Imaging Station (DIS, above right), as it has all the bits needed to inspect your work and display the images on a PC (not included) without the fuss of optical microscopy.
