Automatic TLC Sampler 4 (ATS4)

The ATS 4 is a device for fully automated sample application onto TLC and HPTLC plates. Samples can be applied as bands, spots or rectangles.


Automatic sample application is a key factor for productivity of the HPTLC laboratory. The ATS 4 offers fully automatic sample application for qualitative and quantitative analyses as well as for preparative separations. It is suited for routine use and high sample throughput.


Key Features

  • Application of bands, spots or rectangles
  • Any plate format up to 20 x 20 cm
  • Spray-on application or by contact transfer
  • Software-controlled by visionCATS
  • Heated Spray Nozzle (option)

Precise sample application is a crucial factor for the quality of the HPTLC analysis. When using visionCATS HPTLC software to control the ATS 4, a fully automated sample application for routine use and high sample throughput is supported.

The dialog box for instrument parameters offers user-friendly default combinations. For instance, by selecting the solvent type most similar to the solvent actually used, the software automatically adapts the instrument defaults to match viscosity, volatility and surface tension. The filling/rinsing quality which determines how often the syringe is rinsed, the filling process repeated, etc., can be individually adjusted to a specific task.

The sample table is clearly arranged and easy to use. The application progress is displayed on screen as long as the instrument remains connected to the computer.
