Abstract: A weighing apparatus is provided that quantifies an impact load based on an electrical output from a mass sensor to prevent damage to the mass sensor by disclosing the degree of impact to a user. The weighing apparatus includes a weighing unit on which an object is placed and a mass sensor that receives the mass×acceleration of gravity of the object as a load and measures mass from an electrical signal corresponding to displacement of an internal structure of the apparatus. The apparatus quantifies and records the amount of the displacement, and determines acceleration by a numerical calculation from the displacement data. The obtained acceleration quantifies the amount of impact applied on the weighing apparatus by the object, and may be used to warn the user when the weighing apparatus is in danger of damage.

Abstract: Operability, accuracy, and safety when fitting a glass-made pipette tip to a pipette are improved. A pipette tip fitting adapter includes a hollow body having one end portion configured to serve as a tip inserting portion into which a pipette tip is inserted, and the other end portion configured to serve as a pipette inserting portion into which a pipette is inserted, and at an opening side of an inner circumferential surface of the tip inserting portion, seal portions projecting inward are formed in a circumferential direction. Accordingly, a pipette tip that is long and heavy like a glass tip can be held.

Abstract: Provided is an electronic balance that enables a user to recognize the magnitude of disturbances in real time. An electronic balance (1) whose natural frequency is known, includes a load measurement mechanism (4) configured to detect weighing data (Zn), and an arithmetic processing unit (8) configured to perform arithmetic processing by using the weighing data (Zn), wherein the arithmetic processing unit (8) extracts a vibration component (Fr) of the natural frequency from the weighing data (Zn) detected by the load measurement mechanism (4) and displays the vibration component (Fr) of the natural frequency. By using the vibration component (Fr) of the natural frequency as an index of disturbances, it becomes possible to recognize in real time the magnitude of the disturbances during weighing.
