A toilet for administering a product to a user is disclosed. The toilet includes a bowl, a mechanism for administering the product to the user, a storage structure for storing the product, a sensor that detects a property of the product, and a processor. The bowl is adapted to receiving excreta from the user. The processor compares the detected property with a range of values indicating the suitability of the product for being applied to a user. The processor generates an alert when the detected property falls outside the range of values.

A system and method for automated transfer of a tape segment onto the face of a tissue block to be thin sectioned by microtomy includes applying, to a carrier strip, a plurality of serially-spaced patches of sample tape having an adhesive outer surface, transporting the carrier strip along a path adjacent to and spaced from the exposed sample surface to position one of the patches of sample tape adjacent to and covering the exposed sample surface, adhering the one of the patches of sample tape to the exposed sample surface.

The invention relates to an electrophoresis device (1) for use in a method for producing transparent biological samples (2), comprising a reaction frame (3), the reaction frame (3) having an open top side (4) and a bottom side (5) opposite the top side (4), characterized in that the bottom side (5) has at least partially one opening (6). The invention also relates to a use of a sample cassette (19) for an electrophoresis method.

The technology disclosed herein relates to, at least in part, a removable imaging cassette. An illumination plate is configured to transmit light. A cassette body defines an outer surface and a cassette cavity within the outer surface, where the outer surface surrounds the illumination plate. The cassette cavity abuts the illumination plate. A light source is disposed in the cassette cavity. Mating electrical contacts extend through the outer surface of the cassette body, where the mating electrical contacts are operably coupled to the light source.

A tape (170) includes a bottom film (410), upon which dry sticks (180a, 180b, 180c) are separately arranged, which dry sticks (180a, 180b, 180c) are configured to indicate at least one biomarker value of a milk sample of an animal (100); and a top film (310) covering the plurality of dry sticks (180a, 180b, 180c), the top film (310) being arranged on the bottom film (410), the top film (310) being arranged to be peeled off an individual dry stick (180a, 180b, 180c) before application of the milk sample to the dry stick (180a, 180b, 180c).

The biological information detection sensor supply device is provided with a main body case having a supply port to which a biological information measurement device can be attached, a housing unit for housing a biological information detection sensor and a sensor supply film including a cover film and a holding film for sandwiching the biological information detection sensor, and a supply unit for supplying the biological information detection sensor from the housing unit to the supply port. The supply unit supplies the biological information detection sensor to the supply port, and separates the holding film and the cover film from the sensor supply film in a state before the biological information detection sensor is supplied to the supply port. At the supply unit, the biological information detection sensor supplied to the supply port is fitted to the biological information measurement device fitted to the supply port.

The invention relates to a method of preparing a biological sample for study in an analysis device, said method comprising the steps of: providing a biological material to be studied; providing a sample holder that is configured to be placed in said analysis device; and transferring said biological material onto said sample holder for preparing said biological sample. According to the invention, the method comprises the steps of: acquiring a specimen of said biological material provided on said sample holder; transferring said specimen to a screening device for screening said specimen; and evaluating said biological sample based on results obtained by said screening device. With the method, time and resources may be more effectively used in studying biological samples, for example using charged particle microscopy in the form of cryo-EM.

Methods, apparatuses and systems for facilitating automated or semi-automated collection of tissue samples cut by a microtome. In one example, a collection apparatus may be moved back and forth between respective positions at which the collection apparatus is operatively coupled to a microtome so as to collect cut tissue samples, or routine access to the microtome is provided. Relatively easy movement and positioning of the collection apparatus is facilitated, while at the same time ensuring structural stability and appropriate alignment and/or isolation between the collection apparatus and the microtome. A fluid reservoir receives samples cut by the microtome, and the collection apparatus may collect samples via a conveyor-like substrate disposed near/in the reservoir. A linear movement of the substrate may be controlled based on a cutting rate of the microtome, and the fluid level in the reservoir may be automatically maintained to facilitate effective sample collection.

An instrument for processing a biological sample includes a chassis. Connected to the chassis is a tape path along which a tape with a matrix of wells can be automatically advanced through the instrument, a dispensing assembly for dispensing the biological sample and a reagent into the matrix of wells of the tape to form a biological sample and reagent mixture, a sealing assembly for sealing the biological sample and reagent mixture in the tape, and an amplification and detection assembly for detecting a signal from the biological sample and reagent mixture in the matrix of wells in the tape.
