EKT Electrophoresis Capillary Burner

Price $828

The removal of the polyimide coating in order to provide a UV transparent window is often a source of inaccuracy in CE experiments. For convenient and reproducable preparation of UV transparent windows in polyimide covered capillaries, EKT have developed an easy to use capillary burner device. The capillary is simply pushed through the guide holes until it reaches the correct position for the window as chosen by the user and the simple push of a button initiates a controlled heating of the capillary making a small, precise and highly reproducable window. Precise and Reproducable Easy to Use Produces Clean Finish Saves Time and Money Long Life Filament The EKT burner uses a special oxidation resistant nichrom wire filament which can be used for the prepartion of many hundreds of capillaries before it requires replacing. In addition to our standard filaments which produce a 2mm length window, we also produce 1mm and 3mm filaments. Low cost replacement filaments are available in all three sizes. The diagram below shows a close up of the capillary in the filament holder ready. The capillary is easily inserted into the device via accurately positioned guide holes. Burner Filaments The EKT Capillary Burner is delivered fitted with a standard burner filament which produces a detection window with an approximate length of 2mm. This standard filament can be removed and replaced with a filament producing a longer or shorter window in accordance with the analyst's requirements. Burner filaments are available in three different coil lengths: 1mm, 2mm and 3mm. The diagram below shows an example of four different windows created using the standard 2mm burner coil on a 50um i.d. 375um o.d. capillary. The high degree of reproducability of windows produced using the EKT burner is clearly evident. (Test carried out by an independent laboratory)
