Estimating the term…
An apparatus for applying a liquid sample onto a culture medium in a spiral shape, for example, for determining the bacteria concentration therein, having a line that has an incline nozzle for applying the liquid sample onto the culture medium. A turntable supports a culture medium container and the line is supported by a linearly movable slide. The position of the nozzle relative to the turntable is automatically adjusted in response to a signal from a sensor, which detects the level of the upper surface of the culture medium. An automatically controlled movement mechanism, together with a level control device or a disinfecting container, insures that the nozzle is submerged deep enough into the disinfectant to properly disinfect the outer side of the nozzle.
An apparatus for applying a liquid sample onto a culture medium with a prescribed quantity and distribution, the apparatus comprising a syringe and a line connected thereto and having at one end a nozzle with an oblique cut tip for delivering sample liquid and at its other end being exchangeably connected to the syringe with a nipple, wherein for positioning said nozzle the line is connected to a movable carrier with a mounting means for unambiguously and exchangeably mounting the nozzle in a fixed position relative to a holder of the carrier.
A line for use in an apparatus for applying a liquid sample onto a culture medium with a prescribed quantity and distribution, which line is connectable to a syringe and comprises at one end a nozzle with an oblique cut tip for delivering sample liquid and at its other end being exchangeably connectable to the syringe with a nipple, wherein for positioning said nozzle the line has mounting means for unambiguously and exchangeably mounting the nozzle in a fixed position relative to a holder of a carrier.
