Spray-on technique: high accuracy and perfectly reproductible sample deposits. Dual syringe system: dosing and filling syringe. Low sample requirement Application of dots or lines. Protective cover prevents external contamination. Circuit rinsing before each application Stand-alone or PC-controlled. Easy-to-use software, transferring data to Densitometer CD60 Holding up to 10 methods Volume spotted on the HPTLC plate: from 0.1µl to 1 ml. Can be easily upgraded to fully automatic. The AS30 semi-automatic HPTLC sample applicator, which works according to the spray technique, allows the deposition of substances in lines or dots on HPTLC plates or sheets up to 200 x 200mm, in a fully parameterisable way, thanks to compressed air flow without contacting the plates. The parameters of 10 methods can be programmed and saved with the integrated software. The sample application is carried out automatically, only filling and inserting the syringe is made manually. A dosing syringe is fixed at a movable turret. Therefore, removing and new adjusting of this syringe for every application is not necessary. The AS30 semi-automatic HPTLC applicator is scalable. It can be upgraded to a fully automatic version by simply connecting it to the BS35 auto-sample.
