Product Description

The LABMAN AAS4M is a manual flame atomic absorption spectrophotometer with a 4-lamp option for the quantitative determination of metal elements. It covers 190–900 nm with a Czerny-Turner closed optical system, a 1800 lines/mm grating, air-acetylene flame, automatic slit switching and background correction by self-reversal or D2 lamp.

Key features

  • Flame atomic absorption with air-acetylene fuel gas; 4 lamp sockets
  • Automatic gas control and optimisation of flow and pressure
  • Czerny-Turner closed optical system on an integrated optical bench
  • 6-gear automatic slit switching from 0.1 to 2.0 nm
  • Background correction by high speed self-reversal (BGC-SR) or D2 lamp (BGC-D2)
  • Copper hollow cathode lamp supplied as standard; other lamps optional
  • Standard software supplied; computer not included
  • Used for random elemental analysis in R&D laboratories and educational institutions

Frequently asked questions

What does the AAS4M measure?

Metal elements in a sample. Free atoms in the flame absorb light at element-specific wavelengths and the absorbance is proportional to concentration.

What is the difference between the AAS4M and AAS8A?

The AAS4M is manual with 4 lamp sockets and flame operation. The AAS8A is automatic with 8 lamp sockets and supports flame and graphite furnace, with a lower Cu detection limit of 0.004 µg/ml.

Which gases and accessories are needed?

Acetylene and air. An oil-free air compressor (ACOF30) is available as an accessory at additional cost.

Can I add a graphite furnace to the AAS4M?

The catalogue lists the AAS4M as a flame instrument and the graphite furnace as an accessory for the AAS8A. Contact Labmart before planning a graphite furnace set-up.

Is a computer included?

No. The software is supplied with the instrument but you need your own computer.

What power supply does it need?

AC 220 V, 50–60 Hz (without power fluctuation).

What is supplied with it?

Main instrument, Cu hollow cathode lamp, software. A computer is not supplied; the user must have a computer to run the software. Instruction manual, test certificate.

What are the packing size and weight?

860 × 710 × 760 mm (L×W×H as per catalogue), gross weight 96 kg.

Can I get a GST invoice and a bulk or institutional quotation?

Yes. Labmart (Chemlab Equipment) supplies against a GST invoice and provides quotations for colleges, hospitals, pharma companies and government labs, including bulk and tender requirements. Contact us with your requirement for a formal quotation.

What is the warranty and delivery time?

LABMAN instruments supplied by Labmart carry a standard 13-month warranty. Delivery time depends on your location and stock, so please contact Labmart for a delivery estimate.
