A microscope slide dispenser is formed with a slide case dispensing attachment having a slide dispensing mechanism and a disposable, plastic slide case that is removably coupled to the dispensing attachment. Positioning members on the dispensing attachment interact with corresponding members on the case to properly position the slide relative to a seating platform or slide case seat. A slide carrier has a finger that projects outwardly from the dispensing attachment and toward the slide case to engage the rear edge of the closest of a plurality of microscope slides stacked within the case. The case is provided with a carrier finger opening and a slide dispensing slot. Operation of the dispensing mechanism engages the carrier finger behind the slide closest to the end wall at which the dispensing attachment is located. The carrier finger pushes the microscope slide closest to the end wall at which the dispensing attachment is located out of the slide case through the slide dispensing slot. The carrier may be spring-biased so that the slide-engaging finger returns to a slide-engaging position behind the next slide, which moves into place once the slide aligned with the slide ejection slot has been ejected. Once all slides have been ejected from the case, the case is discarded.

The invention discloses a complete set of device for an SCGE (single cell gel electrophoresis) test, comprising a box body and a box cover. A grid-shaped bracket is arranged in the box body, and glass slides are respectively arranged in grids of the bracket. Each glass slide is composed of a horizontal bottom plate, two lateral plates and flat plates. The two lateral plates are vertical to the bottom plate. The flat plates which are parallel to the bottom plate are respectively arranged at the upper ends of the two lateral plates and extend outwards. A sample inlet hole corresponding to the grids of the bracket in the box body is arranged on the box cover, and is sealed by a partition pad for a sample inlet gun head to penetrate through. By integrating sample preparation and storage of the SCGE test, the device is convenient for use; gel cannot easily shed off; in addition, the device can realize mass preparation of samples, quicken the sample preparation and increase the success rate, thereby ensuring high efficiency and accuracy of the SCGE test.

The invention relates to a pretreatment method of microchemical analysis of a pectoral fin strip of a Chinese sturgeon, and belongs to the technical field of biological monitoring environments. The pretreatment method includes the steps that a small section of the pectoral fin strip of the Chinese sturgeon is washed and dried in the air, the pectoral fin strip is fixed to a cube resin block, aftersolidification, the cube resin block is fixed to the upper surface of a bottom plate of a mold in an upright manner, a reagent is prepared, the reagent is added to the fixing mold to form cylindricalresin, the cylindrical resin is polished, the pectoral fin strip is transferred to a glass slide, and pectoral fin strip slices are formed, washed and then dried. According to the pretreatment methodof microchemical analysis of the pectoral fin strip of the Chinese sturgeon, on the premise of satisfying sample conditions required for microchemical analysis, combined with the body characteristicsof the biological tissue of pectoral fins of the Chinese sturgeon, pectoral fin strip samples of the Chinese sturgeon processed by the treatment method can meet the multiple analysis requirements ofelectron probe analysis, laser ablation inductively coupled plasma mass spectrometry and the like, and sample pretreatment methods required for microchemical analysis of the pectoral fin strips of various Chinese sturgeons are unified.

The invention discloses a door glass guiding part for a shower room. The door glass guiding part comprises a main body, wherein a vertical column is arranged on the main body; a guiding hole is formedin the vertical column; a guiding wheel is arranged in the guiding hole; an extended mounting arm is arranged on the main body; a screw groove is formed in the mounting arm; and a convex clamping part is arranged at one end part of the mounting arm. The door glass guiding part disclosed by the invention is fixed through the mounting arm and the screw groove in the mounting arm; then, sliding doorglass is arranged on the mounting arm and the guiding wheel clings to the sliding door glass; and when the sliding door glass moves left and right, the guiding wheel on the vertical column achievinga guiding effect, so that a glass sliding door is not easy to fall out of a sliding rail and is convenient to use.

The invention relates to a gene chip for detecting transgenic plants and products containing screened gene NOS, belonging to the technical field of biological engineering. The chip comprises a glass slide with an aldehyde group modified surface, a screened gene NOS probe coated on the glass slide in an array mode, and a positive control, a hybridization positive control, a positive quality control probe, a negative quality control probe and a blank control which are fixed by nucleic acid, wherein the sequence of the screened gene NOS probe is NH2-(CH2)6-O-Poly (dT)15-AAGCATGTAATAATTAACATGTAATGCATGACGTTATTTA. The gene chip for detection of the screened gene NOS of the transgenic plants and the products of the invention can carry out specific detection on the screened gene NOS of the transgenic plants and the products thereof and has high specificity.
