A perchloric acid fume hood is an experimental equipment used to treat toxic gases such as perchloric acid, and is widely used in chemical laboratories, pharmaceutical factories, and other places. Its main function is to effectively prevent toxic gases such as perchloric acid from causing harm to laboratory personnel and the environment. 1. Tested by a third-party testing agency accredited by the state with CMACNASILAC-MRA, in compliance with the national standard JB/T6412-1999
Cabinet: The cabinet adopts a double-layer structure, with a sandwich layer between the outer shell and the inner lining to accommodate water, electricity, and gas pipeline systems, and ensure the airtightness and protection of the cabinet. Bottom cabinet: Made of PP material color matching board that is resistant to strong acids, strong alkalis, and corrosion. It adopts a large number of "mouth", "groove", and "T" reinforced structures, with stable physical structure and super strong load-bearing capacity.
Operating table: Made of board materials that are consistent with the cabinet. Guide plate: Made of a brand new 8.0mm PP plate welded together, it has strong acid and alkali resistance and corrosion resistance. It is installed at the rear and above of the workspace, forming an air chamber between the workspace and the exhaust pipe connection, and uniformly discharging polluted gases. The guide plate is combined with the cabinet using guide clips and can be disassembled and reassembled repeatedly.
Window sliding door: Adopting customer demand integrated molding, movable vertical window sliding door. Placed between the workspace and the operator to protect the operator's safety, combined with a balanced position, the window sliding door can be stopped at any moving point, and the view can be completely clear and unobstructed; Gas collection hood: Made of PP plastic material, this hood has a tapered and tapered mouth. The bottom inlet is a rectangular opening, and the top outlet of the cabinet has a diameter of 250mm. The height of the outlet connection pipe is at least 50mm (inclusive), which facilitates the connection of the air duct sleeve. The hood has a good tapered gas collection angle and smoothness. The length of the bottom long opening is at least 2:1 in ratio to the diameter of the top circular outlet, and the tapered angle is at least 30 degrees (inclusive) to achieve good gas collection uniformity and low pressure loss. Fluorescent lamp: The lampshade is made of 8mm thick PP full cover, with a 5mm thick matte acrylic glass at the bottom. In addition to isolating contact with the gas inside the cabinet, it also has a pressure relief port function. Control panel: Adopting a liquid control panel, equipped with buttons for power, switches, lighting, fans, and operation indicator lights. The LCD display screen can clearly display the operation status of the fume hood. The lower cabinet body is made of a new PP color matching board welded and processed by carving and bending to form the whole cabinet, which has strong acid and alkali resistance and corrosion resistance. All door panels are constructed with folded edges, which are sturdy, firm, and not easily deformed, and have an overall beautiful and elegant appearance. Chain comparison: using laboratory specific PP chain comparison, with strong corrosion resistance. Sink: Made of PP cup trough, resistant to strong corrosion, with filtering and odor blocking functions. The water storage elbow is made of high-density PP.
