Abstract
A specimen carrier is located in a clearly defined flow path of a treatment liquid in a treatment chamber. This treatment chamber is integrated with a conveying unit to one structural unit. For a realistic representation of the treatment operation the conveying unit comprises a pump having a rotating conveyor part for generating a non-pulsating flow. This flow can thereby be reversed by a reversal of the sense of rotation of the conveying part.
Claims18
A laboratory apparatus having minimal dead space for a wet treatment of textile materials, including a specimen carrier located in an exactly defined path of flow of a treatment liquid in a treatment chamber which in turn is integrated with a conveying unit for said treatment liquid into a structural unit, said conveying unit comprising a pump having a rotating pumping means comprising a rotary vane pump for generating a nonpulsating flow of the treatment liquid of which pumping means the sense of rotation is reversible whereby the flow in said path of flow can be reversed.
