PURPOSE: To drip a certain amount of sample liquid continuously and accurately by providing a drip port for dripping sample liquid stored within a container at either the container main unit or cover and by providing a ventilation port for feeding air into the container at the other.
CONSTITUTION: Both a container main unit 6 and a cover 7 are translucent and consist of a reinforced plastic which does not change its form easily. When a sample liquid 1 is stored, it can be visually confirmed from the outside. Lower a dripping port 8 of the container and then mount the container to a main unit 10 to drip the sample liquid 1. The sample liquid 1 will not be split even if the container is turned upside down since the aperture of drip port 8 is small. Then, push the tip of an air injecting pipe 1 to a ventilation port 9 by driving a motor 13. The tip of the air injecting pipe is provided with a packing 21 to prevent air leakage. Then, an air feeding motor 19 drives a piston 18, pushed out air into a cylinder 16 by driving a piston 18 to allow a certain amount of sample liquid 1 to be dripped on a film 5 from the dripping port 8. By changing the film 5 one by one, a continuous measurement is enabled by injecting a certain amount of sample liquid 1.
