Civil engineering part Waterway acceptance: Circuit modification acceptance: First of all, check whether the quality of the used materials meets the requirements of the current national standards. The copper wire with cross-section of not less than 2.5mm2 shall be used for the electric lines. The concealed surface shall be used for laying the wall and the ground. The conduit shall be threaded and the PVC pipe shall be used for home decoration. The junction box must be provided with a line box. Secondly, check whether the power supply, switch, telephone line, closed-circuit television line, and communication line are arranged in accordance with the agreement. The wires and telephone lines, closed-circuit television lines, and communication lines must not be installed in the same pipe. Precautions: The power socket shall adopt three-color lines, in which the blue line shall be adopted for the zero line, the yellow-green line shall be adopted for the ground line, and the spacing between the wire, switch, socket and gas pipe shall not be less than 15cm. Waterproof acceptance: Check that the height of contact with the wall around the waterproof layer is not less than 30cm. The 24-hour storage test should be done without leakage. Acceptance of tiles: First, check whether there are empty drums, skews, missing corners, and cracks in the wall tiles. Second, check whether the yin and yang angles are vertical. The surface flatness is no more than 2mm, the verticality is no more than 2mm, and the seam height is no more than 0.5mm. The seam is not more than 2mm straight, and the seam width is not more than 1mm. Matters needing attention: Try to buy better quality tiles for construction. Wood production section: Before starting work, it is necessary to check whether the inspection site material is consistent with the contract and whether it meets the requirements of the current national standards. It is best to communicate with the contractor before the start of construction to reconfirm the content of the construction project so as to avoid rework and waste. After the wooden production part is completed, it is first checked whether the manufactured objects are constructed according to the design requirements. The doors, windows, sleeves, and cabinets shall be straight and firm, and the surface of the wooden veneer shall be smooth, uniform in color, and have no phenomenon of sawing and hoeing; The cap is plunged to about 1mm below the panel surface; the door and window installation should be straightforward, flat, flexible and non-overturning, the opening direction should meet the design requirements, the hardware installation should be complete, the wood screw tightened; the ceiling and partition wooden The keel shall be painted with fireproof paint, and the keel is straight and free from deformation; the height of the door leaves and the floor left seam shall be controlled at 6-10mm. Finishing part: Before starting work, it must check whether the inspection site material is consistent with the contract and whether the quality meets the requirements of the current national standards. After finishing the inspection, the surface quality of the finish should be free of peeling, brushing, bottoming, falling, etc. The hardware and glass are clean. Before painting, the latex paint must be firmly bonded between the plastering layers and between the plastering layer and the substrate, without delamination, hollowing and cracking. The simplest acceptance method is that the spot is 1.5 meters away from the wall and the brushing pattern is smooth. The acceptance of the wallpaper is the same as 1.5 meters from the wall without seams. Table stone installation part: The installation of stone countertops should be completed before the completion of the finishing of the wooden parts (for example, sill plates). Firstly, check whether the countertops are firm and even in color, and then check whether the joints on the countertops are firm and the flatness is not more than 200.

First of all, check whether the quality of the used materials meets the requirements of the current national standards. Secondly, check whether hot and cold water are arranged in accordance with the agreement. Concealed water supply pipelines should not have joints as much as possible, and if any joints must have maintainable inspection openings. The water pipe cannot be near the power supply, and the distance between the water pipe and gas pipe should not be less than 5cm.

What Are PCR Plates?
Researchers often use PCR plates in high-throughput screening thermocycler applications due to their compatibility with most thermal cyclers. The uniform and thin walls enable a precise thermal transfer. The wells are often raised slightly to accommodate sealing mat, film, and foil. They are also autoclavable.
