Small enclosed operation workstation (also known as a glove box operation unit) is a compact, sealed device tailored for precise, isolated fine operations. It features a sealed cabinet design with a transparent top viewing window (for real-time monitoring of internal work) and two side operation ports equipped with protective gloves—this design allows operators to reach inside for operations while isolating them from workpieces or process media. Additionally, the workstation is fitted with built-in internal lighting (to enhance visibility during operation), a bottom storage/collection tray, and stable base feet (with optional mobility features available). It is mainly used for fine operations requiring environmental isolation, such as precision surface treatment (e.g., small-part sandblasting, fine grinding), dust-free handling (e.g., electronic component assembly, sample processing), and contaminant-free small workpiece finishing. Its sealed structure effectively prevents dust leakage and protects operators, making it well-suited for laboratory or small-batch workshop scenarios.
