An improved apparatus and method for sampling of solids with flexibility to sampling weight and granular size comprises, in one implementation, a sample holder, a grinding unit, a linking channel, a structural support unit and a control unit. The linking channel is arranged to connect the sample holder to the grinding unit. The grinding unit includes a grinding container and a grinding rod with a blade at a bottom end, and is configured to automatically grind a solid specimen. The structural support unit is configured to provide system stability and to protect the control unit from outside. The control unit includes a switch, a regulating module, an actuator motor, a rotational plate, a lever beam and an electronic board, and is configured to regulate automatic weighing and grinding of the solid specimen. The switch is configured to START/END grinding and to send signals to the electronic board to stay ON/OFF during sampling, and the regulating module is configured to adjust voltage of the actuator motor consistent with weight of the solid specimen. The control unit is also arranged to be distant from the grinding unit to prevent direct contact between a user and the solid specimen during sampling when dealing with a hazardous specimen.

An improved apparatus and method for sampling fluids without volume limitation comprises, in one implementation, a holder unit, a pumping unit, and a control unit. The pumping unit includes an inlet channel, an outlet channel, a pumping motor, and a circulation hose in which the pumping motor is configured to circulate a fluid specimen from the inlet channel to the outlet channel into the circulation hose. The circulation hose is attached to the outlet channel, and secured to the holder unit displaced from a user to prevent direct contact with the fluid specimen during sampling when dealing with a hazardous specimen. The control unit includes a switch, a regulating module, and an electronic board, and is configured to regulate circulation of the fluid specimen through the pumping unit. The switch is configured to START/END the sampling process and to send signals to the electronic board to stay ON/OFF during sampling, and the regulating module is configured to adjust voltage of the pumping motor consistent with viscosity of the fluid specimen to allow circulation without volume limitation.

A rhythmic pill crusher, including: a crushing cover including a cylindrical boss, wherein a plurality of first threads formed on a first wall of the crushing cover and around a column portion of the cylindrical boss, wherein the first wall is distant from the column portion of the cylindrical boss; and a supporting platform including a cylindrical recess for receiving the cylindrical boss and a plurality of second threads formed, in response to the first threads, on a second wall of the supporting platform; wherein the first threads are loosing engaged with the second threads, the first threads spirally go upward and downward along the second threads, or the first threads suspend relative to the second threads, which allows the first threads to rotates remaining in a same height. The pill crusher can be operated efficiently and easily and can be cleaned easily for reducing cross contaminations.
