Key benefits — why you need this manual lab lift - Precise vertical positioning: smooth manual adjustment across an 85–280 mm range lets you set repeatable, accurate heights for sensors, samples, optics, or instruments. - Stable and durable support: stainless steel construction with a top plate, lower base plate, rotating shaft and hand wheel provides steady, vibration-resistant positioning for classroom and bench work. - Compact and portable: 200 x 200 mm top and base plates give a stable footprint while keeping the unit small enough to move between benches; net weight 1556 g makes handling and storage simple. - Easy, controlled operation: the hand wheel and rotating shaft deliver fine, comfortable adjustments without power or complex setup. Key features and specifications - Function: manual lab lift for raising and lowering objects or instruments - Height adjustment range: 85–280 mm - Construction: stainless steel (top plate, lower base plate, rotating shaft, hand wheel) - Plate size: 200 x 200 mm (top and base) - Net weight: 1556 grams - Designed for classroom and laboratory use in physics, chemistry and biology at the middle-school level How it solves common lab problems - Replaces improvised stacks and unstable supports, giving a level, secure platform for experiments. - Improves experimental repeatability by enabling incremental height changes and consistent alignment. - Reduces setup time: manual hand wheel control is intuitive and requires no calibration or power. Practical use scenarios - Physics optics: raise or lower a lens, light source, or screen to measure focal length or align an optical path during demonstrations. - Chemistry experiments: position a sample container or sensor at a precise height for titration, observation, or instrument interfacing without shifting other apparatus. - Biology demonstrations: adjust the height of a petri dish or specimen stage under a dissecting microscope or camera for clear observation and imaging. Suitable environments - Middle-school science classrooms, teaching labs, and bench-top demonstrations where a reliable, easy-to-use height-adjustment tool is required. What makes this unit stand out - Simple, robust stainless steel build for long service life - Wide, usable lift range with fine control via hand wheel - Compact footprint and light weight for flexible classroom and lab use
