Regular maintenance of the laboratory can effectively prolong the service life of laboratory furniture and equipment. At the same time, it can detect some hidden safety hazards in the laboratory on time and avoid some safety accidents caused by aging or improper use of equipment.
Daily Maintenance of Lab Fume Hood
① Regularly use neutral detergent to clean and scrub all parts of the fume hood, including the glass window, the inner lining board, and the inside and outside of the deflector.
②Regularly lubricate the sliding rails, cables, and balance pulleys of the adjusting door.
③ Regularly test whether each remote control device (faucet, gas cock) can work normally.
④ Regularly check the exhaust outlet pipeline, especially whether there is leakage between the exhaust hood and the pipeline.
⑤ Regularly check the inside of the exhaust hood, especially whether there is an accumulation of impurities in the elbow. Although the fume hood countertop can withstand high temperatures, it is not recommended to be in direct contact with an open flame and high temperature for a long time. When using the electric furnace, it is necessary to add asbestos pads or triangular brackets for heat insulation; for example, electric furnaces with large wattage should be backed with pads, and should not be stored for a long time, so as not to affect the use of the fume hood.
⑥Although the fume hood countertop has good corrosion resistance to various chemicals, and it may still be affected by prolonged immersion and contact. Therefore, it is recommended that if any chemicals drip on the countertop, they should be removed as soon as possible.
Laboratory Furniture Maintenance
Laboratory furniture cannot be exposed to the sun for a long time, damaging the coating on its surface and causing dullness.
If there are scratches on the laboratory furniture accidentally, it can be painted with a similar color pigment and then waxed to make the scratches less conspicuous.
Do not wash the laboratory furniture with boiling water that is too alkaline or too hot to prevent damage to the paint surface of the laboratory furniture.
Wooden laboratory furniture should not be placed in damp and stuffy places, which are easy to mold.
Desks and lab filing cabinets should pay attention to their load capacity to prevent deformation due to pressure.
Laboratory furniture is best maintained regularly, such as regular waxing, to keep its surface shiny.
Laboratory Workbench Maintenance
(1) Phenolic Countertop Workbench:
The surface of the Phenolic board workbench should be cleaned with warm water, acetone, or mild detergent. The detergent used for washing hands or dishes can be used. Do not use detergents with abrasives and strong acids to avoid damage to the surface. For stubborn stains, drop the hypoxic acid on the contaminated surface of the Phenolic board and wash it with clean water.
(2) Ceramic Countertop Workbench:
Hydrofluoric acid has different degrees of influence on the countertop, so it should be used with caution, and a layer of plastic pad or rubber pad should be added to protect it.
Conventional countertops only need daily cleaning, and absorbent liquids must be wiped with toothpaste or oxalic acid thinner.
Do not use hard objects to scratch the tabletop. Try to lift the table top gently when moving, and avoid dragging.
(3) Epoxy Resin Workbench:
Oily scratches caused by metal, rubber, and similar objects can be wiped off with a cloth dampened with naphtha or solvent.
Regularly clean and polish with a paper towel or a clean rag, or use varnish for cleaning and polishing.
If you want to restore the original luster of the countertop, wipe the surface with a cloth dampened with oil, then dry with a dry cloth.
At present, many laboratory managers do not pay enough attention to the regular maintenance of the laboratory, and there is no special person responsible for regular maintenance, which will cause many laboratories to look old soon after they are built. Many laboratory furniture has been aged or damaged before it has reached its service life, so the maintenance of laboratory furniture cannot be ignored.
