Atomic absorption spectrophotometer BK-AA320N

AASflamewith graphite furnace

Introduction:
The Atomic Absorption Spectrophotometer (AAS) BK-AA320N is a high-precision analytical instrument for detecting and quantifying metallic elements in liquid and solid samples.

Product details:

• Brand: BIOBASE
• Product origin: CHINA
• Delivery time: Within 7 days
• Supply capacity: Factory direct supply
• Model: BK-AA320N

Features:

• Built-in computer data processing and LCD display.
• Double-beam optical system compensates source and wavelength drift due to temperature and electronics variations.
• Short lamp warm-up: hollow cathode lamp allows immediate sample analysis.
• High measurement precision: gas path with pressure and current stabilizers for a stable flame and low noise; fine light beam ensures low characteristic concentrations.
• High-energy optical path and long-life, corrosion-resistant atomization system.
• Multi-functional analysis modes: flame absorption, flame emission, graphite furnace AAS, hydride generation.
• Safe gas path: quick gas conversion and safety protection enable air–acetylene operation and analysis of over 60 elements.
