High-throughput：Concentrating 200 tubes of 1.5ml/5ml simultaneously. The temperature is lower, the speed is faster, and the cold trap temperature can reach -60°C. Sample protection：Automatic vacuum release during power outage to protect sample safety. 

Personnel safety: Automatic exhaust of waste gas after operation. 

Stability and reliability: High-performance motor, stable electromagnetic drive system, imported pressure relief valve, corrosion-resistant bearings,etc.vacuum delay function inside, which initiates vacuum extraction after the preset speed is reached 

Corrosion resistance: The chamber is made of 304 stainless steel material with a Teflon coating treatment.
