SPOTON TLC SAMPLE APPLICATOR (110 V/60 HZ) A87-30

The TLC SpotON 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. With digital temperature and speed controls, this device delivers the perfect sample application every time.

The unit has been designed for use with custom designed TLC syringes with blunt Teflon coated 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 rates ranging from approximately 5 minutes (fastest speed setting) to 1 hour (slowest speed setting). An integrated 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.
