The HPTLC-Applicator AS30 is a decisive contribution towards modern GxP-conform thin layer chromatography and works according to the spray-on-technique. A stream of gas carries the sample from the cannula tip onto the TLC/HPTLC plate. Therefore, compressed air is needed. This proven principle prevents damage to the layer and allows the application tower to be moved during sample ejection. The samples can be applied on TLC plates, HPTLC plates or foils up to the size of 200 x 200 mm as dot or line. During the filling process, the dosing syringe is positioned over the tray which collects rinsing and flushing solvent and excess sample. The sample is injected into the body of the syringe through a lateral opening. After the syringe has been filled, a stepping motor moves the piston downwards to close the fill port. A second stepping motor moves the tower sideways across the plate. The microprocessor controls the two stepping motors and the gas valve.
