The TLC AUTOSPOTTER is a semi-automated device used to apply samples on Thin Layer Chromatography plates. The instrument eliminates the need for manual sample application and can be used to apply up to 18 samples at a time. The unit has been designed for use custom SGE brand TLC syringes with blunt Teflon tipped needles. These special needles minimize sample " creep back " and enhance reproducibility. The syringes also feature Teflon plunger tips to help eliminate the problem of metal-to-glass contamination. Syringes are available in 10, 25, 50, 100 and 250ul volumes. The device can apply samples at variable rates ranging from 3 minutes (fastest speed) to 30 minutes (slowest speed.) An intergral heater strip runs beneath the TLC plate at the point of sample delivery to aid in solvent evaporation.
By adjusting the delivery rate and temperature of the heater strip, the smallest possible sample zone can be obtained. Syringes must be purchased separately. The unit will operate with as few as one syringe. ·Use of standard TLC syringes ·Conveniently located control switches/knobs ·Digital temperature read-out ·Even drive bar movement for complete dispensing of all sample ·Adjustable needle guide ·Alternative syringe templates available for use with scored and channeled plates
