Product Description

The LABMAN AAS8A is an automatic atomic absorption spectrophotometer with an 8-lamp option for flame and graphite furnace analysis of metal elements. It covers 190–900 nm with a Czerny-Turner closed optical system, 1800 lines/mm grating, automatic gas control and a Cu detection limit of 0.004 µg/ml.

Key features

  • Flame and graphite furnace operation; auto sampler and refrigerated circulating bath can be attached as options
  • Automatic gas control and optimisation of flow and pressure; argon is required for graphite furnace
  • 8 lamp sockets
  • 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

Frequently asked questions

What is the difference between the AAS8A and AAS4M?

The AAS8A is automatic with 8 lamp sockets, supports flame and graphite furnace, and has a lower Cu detection limit (0.004 µg/ml versus 0.008 µg/ml). The AAS4M is manual with 4 lamps and flame only.

Can I use a graphite furnace with it?

Yes. The graphite furnace GF3000 and the 85-position auto sampler ASG85 are available as accessories at additional cost. Argon gas is required for graphite operation.

Which accessories are recommended?

Oil-free air compressor ACOF30, graphite furnace GF3000, auto sampler ASG85, a refrigerated circulating bath for stable graphite furnace cooling, and hollow cathode lamps for the elements you test.

Which hollow cathode lamps are available?

Cu, Zn, Fe, Mn, Pb, Mg, Ni, Cd, Ca, Cr, Li and Co. Copper is supplied as standard.

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 93 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.
