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.

Abstract: A bio-sample image pickup device includes a light source module, a carrier, an image pickup unit, a first filter set, and a second filter set. The carrier carries the light source module and the bio-sample, and moves between a first position and a second position. The first filter set between the light source module and the image pickup unit for filtering the light emitted by the light source module, and the image pickup unit picks up the image of the bio-sample through the first filter set in the first position. The second filter set in the second position filters the light emitted by the light source module for allowing an operator to see the bio-sample in the second position through the second filter.

Abstract: A real-time fluorescent electrophoresis apparatus, comprising: an electrophoresis tank comprising a platform, an electrophoresis liquid, a positive electrode and a negative electrode, the platform carrying a gel with a biological sample, the gel comprising a plurality of charged molecules of the biological sample, and the gel, the platform, the positive electrode and the negative electrode being immersed in the electrophoresis liquid; and a lid covering the electrophoresis tank and comprising a filter disposed above the gel and at least one luminous element disposed on at least one side of the filter to irradiate the gel so that the biological sample in the gel is excited to fluoresce. Thereby, the experimenter is able to observe fluorescence phenomenon from the biological sample during electrophoresis so as to trace the electrophoresis process and determine whether the electrophoresis process is to be interrupted and avoid experimental errors.

Abstract: An ultraviolet light source includes a casing holding therein UV lamp tubes and a translucent panel above the UV lamp tubes, a filter panel, a side frame surrounding the filter panel, and a hinge connected between the casing and side frame for enabling the filter panel to be turned with the side frame about the axis of the hinge relative to the casing. Moreover, the hinge and the side frame are made of metal material or metal alloy for avoiding breakage of the part of the filter panel connected with the hinge under long radiation of the emitted ultraviolet light. When in use, a bio-sample is placed on the translucent panel, and then the filter panel is closed on the casing over the bio-sample, so that the user can observe the bio-sample or pickup the image of the bio-sample without exposing the body to the emitted ultraviolet light.

Abstract: A bio-sample image pickup device includes a light source module, a carrier, an image pickup unit, a first filter set, and a second filter set. The carrier carries the light source module and the bio-sample, and moves between a first position and a second position. The first filter set between the light source module and the image pickup unit for filtering the light emitted by the light source module, and the image pickup unit picks up the image of the bio-sample through the first filter set in the first position. The second filter set in the second position filters the light emitted by the light source module for allowing an operator to see the bio-sample in the second position through the second filter.
