Technical Specifications for Routine Maintenance and Care of Steel-Wood and All-Steel Laboratory Benches

Steel-wood and all-steel laboratory workbenches share similar operating environments regarding their work surfaces, plumbing fixtures, and hardware components; therefore, routine maintenance must be integrated into daily operations through standardized, ongoing management protocols.

As the core component directly supporting experimental activities, the work surface is a primary focus of maintenance. Common work surface materials include solid physicochemical boards, epoxy resin boards, and ceramic boards; all types require protection against prolonged exposure to corrosive agents and physical damage. Immediately after experiments, any residual reagents, solid debris, and liquid spills must be cleaned up. Strong acids, alkalis, oxidizing agents, and organic solvents must not be allowed to remain on the surface for extended periods, and corrosive liquid spills require immediate cleaning with water. Daily cleaning should be performed using a neutral detergent (pH 6–8) and a soft, lint-free cloth; the use of steel wool, stiff brushes, or abrasive cleaners is prohibited to prevent physical scratches that could allow reagents to seep into the material and accelerate substrate corrosion. Furthermore, high-temperature vessels and open flames must not come into direct contact with the work surface; high-temperature equipment requires a dedicated heat-insulating pad to prevent heat damage, cracking, or material degradation. Soaking the surface in highly corrosive agents—such as acetone, xylene, or concentrated bleach—is strictly forbidden. Maintenance strategies should be tailored to the specific material: solid physicochemical boards are suitable for standard experiments but lack resistance to prolonged exposure to strong oxidizers; epoxy resin boards offer superior corrosion and heat resistance, making them ideal for frequent, rigorous experimental conditions; and ceramic boards excel in heat and chemical resistance but are brittle, requiring protection against heavy impacts that could cause edge chipping or cracking.

Proper maintenance of the plumbing system is essential for the stability of the workbench. Sinks must be cleared of experimental debris and sediment regularly to prevent blockages caused by accumulated waste. Experimental waste liquids must be collected and disposed of according to strict classification protocols; discharging them directly into the sink is prohibited, as this can cause pipe corrosion and clogs. Faucet cartridges and rotating shafts must be kept clean and dry; remove dust and debris monthly. To address stiffness or sticking during rotation, apply silicone-based lubricant for maintenance; do not use machine oil or heavy grease, as these can trap dust and cause components to seize or rust. If the faucet drips or seals fail, promptly replace the sealing rings and cartridges. Regularly inspect accessories such as drain hoses, sealing rings, and connectors, paying close attention to signs of aging, cracking, or leakage. Clear pipe blockages using physical methods; do not pour in strong alkaline drain cleaners, as these can corrode the piping structure and shorten the service life of components.

Routine maintenance of cabinet hardware ensures smooth operation. Metal components—such as cabinet hinges, drawer slides, and handles—must be kept clean and dry to prevent corrosion from laboratory gases and moisture; perform monthly dust removal and component inspections. If drawers stick or cabinet doors do not open and close smoothly, clear debris from the tracks and apply an even coat of silicone lubricant; avoid using sticky lubricants that attract dust and cause binding. Periodically tighten all hardware screws. For hinges or slides showing minor rust, remove the rust, clean the surface, and apply anti-rust oil; replace components that are severely rusted or non-functional to ensure operational stability.

Adhere to general protective guidelines: strictly avoid heavy impacts or crushing loads on the edges of laboratory benchtops and cabinet structures to prevent physical deformation or damage. Maintain consistent laboratory ventilation to minimize the accumulation of corrosive gases that could damage the equipment. When cleaning the floor, prevent water from pooling around the base of the laboratory benches for extended periods to avoid moisture damage to the substrate, peeling paint, or structural deterioration.
