Ronchi Ruling with Oscilloscope Sweep*
The photographic record illustrates exceptional precision for scanning electrophoresis gels in either the UV or VIS, using the new Gilford Model 2410-S Linear Transport. The new Model 2410-S is an improved version of the widely accepted Gilford Model 2410 Linear Transport. A new line frequency synchronous motor drive gives you even better positional reproducibility. The oscilloscope display was taken from the standard output terminal of a Gilford Model 240 Spectrophotometer. This method makes full use of the resolving power of the Gilford Linear Absorbance Photometer and may be used in your laboratory. The alternative of using a strip
chart recorder will produce comparable results. The new Model 2410-S Is another example of the Gilford program of continuous development of superior devices for simplifying and upgrading spectrophotometric techniques, without making your existing Gilford equipment obsolete. Your present Gilford Model 2410 Linear Transport can be converted to synchronous drive with a replacement kit that Is easily installed In your laboratory. Like other Gilford auxiliary devices, the Model 2410-S is easily Installed on the optical bench rods of your Gilford Spectrophotometer. It can also be adapted to an existing quality monchromator.
