What kind of experiments require the use of high-precision vacuum glove boxes?
Release time:
Nov 17,2025
Experiments that require high-precision vacuum glove boxes are characterized by extremely high demands on environmental impurities (oxygen, moisture, trace gases) or operational accuracy. Once environmental parameters exceed the threshold, they will lead to experimental failure, sample invalidation, or data distortion. Such experiments are mostly concentrated in environmentally sensitive fields such as materials science, electronic engineering, and chemical synthesis.
1.Material preparation experiments: requiring absolute "oxygen-free and water-free" conditions to prevent sample deterioration
The core requirement of these experiments is to avoid reactions between samples and air components. High-precision glove boxes can control oxygen and water content below 1ppm (ordinary glove boxes are usually 5-10ppm), ensuring stable material performance.
① Preparation of core materials for lithium batteries/fuel cells;
② Synthesis of perovskite/organic semiconductor materials;
③ Processing of nano-functional materials.
2.Electronic device manufacturing experiments: requiring "zero pollution" to ensure process accuracy
The core need here is to prevent trace impurities in the environment (such as dust and gas molecules) from affecting device performance. High-precision glove boxes not only control oxygen and water but also filter tiny particles (typically achieving Class 100 cleanliness).
① Packaging of semiconductor chips/quantum devices;
② Assembly of MEMS (Micro-Electro-Mechanical Systems) devices.
3.Precision chemical synthesis experiments: requiring "accurate temperature + gas control" to ensure reaction controllability
These experiments not only need to isolate air but also require precise control of reaction temperature and gas ratio. High-precision glove boxes are often integrated with temperature control (accuracy ±0.1℃) and gas mixing (accuracy ±0.1%) modules.
① Anhydrous and oxygen-free catalytic reactions;
② Synthesis of radioactive/highly toxic reagents.
4.Biomedical experiments: requiring "precision gas control" to simulate special physiological environments
The core requirement is to simulate special gas atmospheres in the body (such as low oxygen, specific CO₂ concentrations) and avoid external microbial contamination. High-precision glove boxes can accurately adjust gas ratios and maintain a sterile environment.
① Cultivation of anaerobic microorganisms/tumor cells;
② Processing of sensitive biological samples.
