Abstract
An apparatus for applying a given amount of blood serum sample to a sample bearing film which has been wetted with Veronal-Veronal soda buffer solution comprises an applicator with an application chip holding a given amount of the blood serum sample, a hygrometer for detecting a humidity of an atmosphere surrounding the wetted sample bearing film, a timer circuit for presetting an application time in accordance with the detected humidity and producing a timing signal when said present application time has elapsed, and a control circuit for receiving the timing signal to drive the applicator to apply the blood serum sample to the film which is in the most favorable wet condition.
Claims5
An apparatus for applying a given amount of a sample liquid to a sample bearing film which has been previously wetted with a sufficient amount of a buffer solution comprising:
- a sample applicator for holding the given amount of the sample liquid to be applied to the sample bearing film;
- wetness detecting means for metering a humidity of an atmosphere surrounding the sample bearing film wetted with the buffer solution to detect a wetness of the film;
- a variable timer circuit for presetting an application delay time as a function of the detected wetness of the film;
- a control circuit in response to a timing signal which is produced from said timer circuit when said preset application time has been elapsed, for actuating automatically said sample applicator to apply the sample liquid to the sample bearing film under such a condition that the film is in a suitable wet condition for being applied with the sample liquid.
