Apparatus for wiping the optical window of a sample cell in a turbidimeter or other particle measuring instrument for analyzing a liquid sample. The wiping apparatus is operated by the pressure of the source of supply of the liquid sample and avoids the necessity of liquid seal bearings.

DETAILED DESCRIPTION An object of the present invention is to provide a cell cleaning device, the moving parts of which are located within the sample cell chamber and therefore avoids the necessity of any packing or sealing between the cleaning device and the sample cell.
Furthermore, the motor power for the cleaning device is derived from the pressure of the sample to be analyzed.
The device for wiping the optical window provided by the present invention can be operated to give a thorough wiping to the inner surface of the sample cell window without requiring the measuring instrument to be disassembled.
Thus, it permits the wiping operation to be carried out quickly and perfectly.
Other objects and characteristic features of the present invention will become apparent from the description to be given in detail hereinbelow with reference to the accompanying drawings.
