Abstract
A flow chamber () made of plastics as an object carrier for light-microscopic examinations comprised at least one channel () in a base plate (), said channel having a width of 0.01 to 20 mm and a height of 0.01 to 5 mm. One liquid reservoir (') each is connected to the inlet and outlet opening (′) of the channel, whereby a communicating system is generated. The bottom and/or the cover of this chamber is made of a high-class plastic material and may be functionalized. The inlet and outlet portions of the channel may be formed by a rounding () of the channel edges or by a surface treatment in a manner that drop formation is prevented and the flow is therefore not obstructed. In a method of sample preparation for light-optical microscopic examinations, a sample flow is generated by a system of communicating pipes, in that a reservoir of a solution with the sample is connected via a third channel with at least one further reservoir and the filling level of the reservoirs differs at the beginning of the examination.
