The present invention relates to a pillar assembly and an apparatus for producing a sample block comprising the same, and according to one aspect of the present invention, it is possible to change arrangement of pillars, and sample slices can be easily obtained from the sample block.

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.

Disclosed are an improved tissue processor and a method of tissue processing performed by the tissue processor. The improved method for tissue processing or the tissue processor is capable of supporting the xylene-free treatment and effectively removing the substitute of xylene (such as isopropanol, IPA), without addition of further protective chemical reagent to remove the isopropanol, thus simplifying the tissue processing method and saving cost significantly.

A method of failure analysis for locating open circuit defect in a metal layers, comprising: providing a chip sample having a metal layer, with an open circuit defect; delaminating the chip to expose the metal layer; depositing a metal conductive layer on the metal layer; removing a portion of the metal conductive layer to expose the metal layer; depositing a non-conductive protective layer to cover the exposed metal layer and any remaining portions of the metal conductive layer; preparing a TEM slice sample which comprises the metal layer, the remaining portions of the metal conductive layer, and the non-conductive protective layer; performing a VC analysis on the TEM slice sample to determine the defect position of the open circuit defect; and analyzing the defect position of the open circuit defect.

A sample preparation mould and a sample preparation method for the triaxial test of MSW are provided. In the present invention, the cylindrical main mould comprises two curved steel pieces, and the two sides of each curved steel piece have a stretched connection part; the two curved steel pieces are connected with each other and clamped by two steel clamps; porous stones are arranged at two ends of the cylindrical main mould and fixed separately by a top limiting lantern ring and a bottom lantern ring; the top limiting lantern ring is detachably connected to the top hopper, from which MSW materials are input; the cylindrical main mould is radially constrained in four positions, and the two ends thereof are axially constrained, thereby significantly improving stability during compacting and hence ensuring the axial and radial sizes of the MSW sample.

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.

A histologic tissue sample support device includes a tissue cassette a frame, and a lid. The tissue cassette has a recess including a body with at least one side wall and a bottom wall and is formed of material that can be successfully sectioned in a microtome and is resistant to degradation from solvents and chemicals used to fix, process and stain tissue. The tissue cassette is movably coupled to the frame. The lid is separably coupled to a peripheral portion of the frame. When the lid is separated from the peripheral portion, the lid and the tissue cassette are capable of moving from a first position to a second position with respect to the frame, and in the second position the bottom wall and at least a portion of the side wall extend beyond a bottom edge of the frame for sectioning in the microtome.

The present application discloses a grouting consolidation sample containing internal defects and the preparation method thereof. Firstly, plasticine is employed to prepare a wax model with the desired defect shape, then a fixing device is used to fix the wax model onto a specific position in a casting mould of consolidation and thereafter a slurry is poured to form a grouting consolidation sample, after the grouting consolidation sample reaches the predetermined strength, the grouting consolidation sample containing the wax model is put into an oven to heat at a temperature above the melting point of wax to demolish the structure of the wax model to form a grouting consolidation sample with internal defects.

A tamper for making paraffin blocks for histology may include a pliable tamper head and a handle. The handle may be permanently or removably attached to the tamper by using screws, magnets, or the like. The tamper may be made from a pliable material, such as a silicone rubber, with improved thermal transfer and high latent heat. In use, the tamper may be warmed in advance to a working temperature by placing the tamper on a hot plate of the embedding station or on a dedicated smaller hot plate. Alternatively, the tamper may be heated with an electric resistive element, a thermoelectric device, or an electric induction coil.

Various implementations include a mold for forming composite samples for a pullout test. The mold includes a body having a first surface and a second surface spaced apart from the first surface. The first surface defines one or more slots and one or more channels. Each of the one or more channels has a longitudinal axis. At least one of the one or more channels intersects one of the one or more slots. Various other implementations include a method of forming a composite sample for a pullout test. The method includes providing a mold as described above; disposing a resin within one of the slots; disposing a fiber within at least one of the channels intersecting the one of the slots such that a portion of the fiber is disposed within the one of the slots; and causing the resin to cure.
