Product Introduction

The Air Dustfall Sample Automatic Concentration and Evaporation Dryer (Dustfall Automatic Concentration and Evaporation Instrument) is used for the pre-treatment of air dustfall samples through concentration and evaporation drying. The entire process automatically monitors the state changes of the concentrated samples without the need for manual supervision, making operation convenient and reducing the labor intensity of laboratory personnel. The Air Dustfall Sample Automatic Concentration and Evaporation Dryer complies with the standard "Determination of Dustfall in Ambient Air—Gravimetric Method" HJ1221-2021. Method principle: Settleable particulate matter in the air settles into a dust collection jar containing an ethylene glycol aqueous solution as the collection liquid. After evaporation, drying, and weighing, the dustfall amount is calculated.
