The purification glove box is a laboratory instrument that fills a closed chamber with high-purity inert gas and filters out active substances through its purification system, bringing water and oxygen to extremely low levels. It mainly removes O₂, H₂O and organic gases. It suits applications requiring an ultra-pure, water-, oxygen- and dust-free environment, such as lithium-ion batteries and materials, ceramics, semiconductors, supercapacitors and special lamps.

Key Features

Leak-free sealing technology: leakage rate < 0.002 vol%/h (industry standard < 0.05 vol%/h)
High-efficiency gas purification system — low water and oxygen concentration
Accurate water/oxygen detection suited to glove box atmosphere; long-life probe protection technology
Professional modular design — easy integration of spare parts
Energy-saving: low regeneration frequency (once a year), typically under 50 W consumption
Ultra-low noise (typically under 40 dB), long sealing life
LM Instruments remote control system — smart control from computers, phones and tablets
