Maintenance of laboratory countertops is an important part of ensuring a clean and safe laboratory environment as well as extending the life of the countertop. Here are some key maintenance steps and considerations:
I. Daily Cleaning
Regular Cleaning: At the end of each day, you should clean the countertop and the surrounding work area in a timely manner. Use a soft rag to wipe the desktop, avoid using too much water or chemical cleaners to prevent damage to the countertop or leave water stains.
Cleaning agent selection: countertop cleaning is best to use warm water, you can also choose acetone or mild detergent, such as hand sanitizer or detergent. But do not choose to contain abrasives, strong acid components of the cleaner, so as not to damage the surface of the countertop. For stubborn stains, hypochlorite can be dropped on the surface of the contaminated corrosion-resistant physicochemical plate, wash with water.
Second, avoid damage
Prevent scratching: Do not use sharp sharp hard objects (such as scissors, razor blades, etc.) to scratch the surface of the countertop, but also can not be used as a surface for cutting and chopping. If there is a broken vessel, you need to use hand tweezers, shall not use a rag to wipe, so as not to cause scratches on the countertop.
Avoid heavy objects: avoid placing overweight items on the countertop for a long time, so as not to cause deformation or damage to the countertop. At the same time, avoid hammering or cutting behavior on the countertop.
Third, to prevent high temperatures and sources of ignition
Avoid high temperatures: Do not expose the experimental bench to temperatures exceeding 135 ℃ for a long time, so as to avoid heat deformation or damage to the table.
Stay away from sources of ignition: the flame of coal vapor lamps or alcohol lamps will damage the table surface, so these sources of ignition should be placed on a tripod or other heat-insulating devices used to avoid direct contact with the table surface.
Fourth, to prevent direct sunlight
Shading measures: Avoid long-term exposure of the laboratory bench to direct sunlight, so as not to affect its appearance or molten metal. In sunny rooms, shade curtains or other sun-shading facilities should be added.
V. Regular Inspection and Maintenance
Check parts: Regularly check whether the screws, connectors and brackets of the countertop and other parts are loose or damaged, and find problems for timely maintenance.
Maintenance of drawers and doors: the doors and drawers of the lab bench should be opened and closed gently to minimize bumping and prolong the service life.
Sixth, storage management
Reasonable storage: laboratory bench cabinets should be stored ordinary laboratory supplies and equipment. For acid, alkali reagents, volatile solvents and other hazardous materials, should be stored in a specialized safety storage cabinet, to avoid direct contact with the countertop.
In summary, the maintenance of laboratory countertops need to start from the daily cleaning, avoid damage, prevent high temperature and ignition sources, prevent direct sunlight, regular inspection and maintenance, as well as reasonable storage and other aspects. Only by doing a good job of these maintenance tasks can we ensure that the laboratory countertops are neat, safe and service life.
