Atomic Absorption Spectrophotometer LX700AAS
Description
Atomic Absorption Spectrophotometer LX700AAS is designed for air-acetylene flame method analysis, flame emission method analysis and graphite furnace analysis etc. Equipped with unique light source system, with 8-lamp turret fully automatic change and optimization, supports 1 lamp working and 7 lamps preheating in the same time. Flame temperature is continuously adjustable between Room temperature~3000oC, which makes it possible to choose the best atomization temperature. Flame will not pollute the environment and is not harmful for human bodies. It’s a break-through in flame AAS analysis.
