SPECIAL VERTICAL EMBEDDING BOX FOR TOMOGRAPHIC PLASTINATION
20210389217 · 2021-12-16 ·

A special vertical embedding box for tomographic plastination comprises two panels oppositely provided and a sealing part provided in the two panels. The two panels are fixed by fixing pieces, and the sealing part comprises vertical sealing strips and a horizontal sealing strip that are connected between the two panels in a fixed manner. The horizontal sealing strip is provided between the lower portions of the two vertical sealing strips, thus forming a flat vertical space with an open upper end and the other three sides sealed. The embedding box is placed vertically during use, so that liquid medicine will not be spilled out. Acetone will escape from the top of the embedding box in the form of air bubbles during an infiltration process, so that there is no need to add polymers twice before curing, thus reducing process steps and drug consumption.

GridTape For Fast Nanoscale Imaging

A tape for collecting tissue samples in a manner compatible with imaging in a transmission electron microscopy (TEM) system, includes a tape substrate having two side walls forming a trough. The trough is defined by a bottom surface of the tape substrate and internal surfaces of the side walls, with an open side therebetween. A support film is attached to a top surface of the tape substrate, and a plurality of apertures is spaced at predetermined locations along the length of the tape substrate, each aperture being covered by the support film. The tape includes a stacked configuration in which the tape substrate is wound in layers, the bottom surfaces of the side walls in one layer being in contact with the support film in an immediately adjacent layer. The apertures in the second layer are aligned within the trough of the first layer, between the side walls.

11320349 · 2022-05-03 · ·

A spheroid tissue microarray comprises an array of tissue spheroids embedded within a porous mold. The product may be impregnated with a wax or resin and sectioned, and contains spheroids which are precisely located in a regular geometric grid. A method of manufacturing a spheroid tissue microarray comprises the steps of: forming a mold of porous material from liquid mold material in a casting mold, and allowing the liquid mold material to set; removing the porous mold from the casting mold; topping up the porous mold with further liquid mold material, and allowing recesses to form in the surface of the mold by the drawing-in of liquid mold material through shrinkage as the liquid mold material sets; placing tissue spheroids into the recesses in the surface of the porous mold; and sealing the tissue spheroids within the mold by topping off with liquid mold material and allowing the liquid mold material to set. An alternative method comprises the steps of: forming a mold of porous material from liquid mold material in a casting mold; allowing the liquid mold material to set; removing the porous mold from the casting mold; placing spheroids in recesses at the bases of wells in the mold of porous material; and sealing the spheroids within the porous mold by adding further porous material on top of the spheroids; wherein the recesses at the bases of the wells in the porous material are formed by protrusions of the casting mold carrying further, nipple-shaped, protrusions.
