Aluminium construction: Made from aluminium oxide material, durability and stability for long-term use. It provides a solid and reliable structure for your woodworking and engraving projects. Adjustable height: The experimental lift features a panel, a base and a rotating shaft system, allowing you to easily adjust the height position of the object support device. With a lift range of 47-110 mm you can easily reach the desired height for your experiments or instrument setup. Smooth handwheel: Equipped with a smooth handwheel, this lifting stand provides easy and precise height adjustment. Turn the handwheel on the front plate to raise or lower the object platform, giving convenient operation and fine control over the lifting process. Wide application: Designed for physical, biological experiments, this lab lifting stand is suitable for lifting objects or instruments. Whether you are conducting research, experiments or working with delicate materials, this lift provides essential support and stability. Use scenarios: - Physics experiments requiring precise optical component positioning, such as aligning lenses or sensors. - Biology experiments lifting microtubes, Petri dishes, or small instruments with stability. - Woodworking or engraving setups supporting small fixtures or tools during setup, testing, or calibration.
