1) Stainless steel material Stainless steel construction provides rust resistance and long service life for continuous use. 2) Smooth and flat Linear surface texture with a smooth, flat surface serves as a stable height-adjustable support for objects. 3) Adjustable and portable The lifting platform delivers stable lifting performance, is height adjustable, and designed for easy transport. 4) Strong carrying capacity The joint uses high-strength, heavy-duty materials to prevent loosening, delivering reliable load-bearing capability. 5) Wide application Suitable for lifting objects or instruments in middle school physics, chemistry and biology experiments. Use scenarios - In physics class, raise sensors or scales for accurate alignment and measurement during experiments. - In chemistry labs, position beakers, probes or small instruments above the workspace for convenient observation. - In biology demonstrations, elevate small equipment to improve visibility and workflow during activities.
