Abstract: The present invention discloses a quantitative micro-volume nucleic acids detection device, which includes a light source, a first shielding screen, a second shielding screen, a lower glass plate, an upper glass plate and at least one sensor, wherein a pin-hole on the second shielding screen generates an image of a nucleic acid sample solution fixed between the bottom and upper glasses, the image is then captured by the sensor, concentration of the nucleic acid sample solution is determined accordingly. With the implementation of the present invention, the detection is reproducible and repetitive, the detection optical path is invariant, avoid of interfering from the pollution during detection so that the cost and time are greatly reduced. Furthermore, in order to overcome the measurement accuracy problem caused from attenuation of light intensity by the prolonged usage of fiber-optic components equipped in the prior art means, it avoid the use of fiber-optic components in the optical path via the present invention.

Abstract: An assistant device for pipetting is disclosed. The assistant device for pipetting comprises: a multi-well plate, a first light emitting element array, a first photo detector array, a second light emitting element array, a second photo detector array, a control circuit, and a display. The multi-well plate comprises a plurality of wells for containing a solution, and the plurality of wells are disposed as an array. The first and second light emitting element arrays are disposed at adjacent sides of the multi-well plate. The first and second photo detector arrays are disposed at the side opposite to the first and second light emitting element arrays respectively. The control circuit is connected to the light emitting element arrays, the photo detector arrays, and the display to determine the amount of pipetting times of each of the wells and display on the display.
