Second hand atomic absorption spectrophotometer price

Based on the physical parameter information of Beijing Puxi TAS-990 series atomic absorption spectrophotometer in the search results, the volume and weight specifications are summarized as follows:

Physical specification parameters

Project specifications

The total weight of the machine is about 35kg (including standard configuration)

The size of the host is not clearly indicated in the search results (designed as a compact desktop instrument)

Supplementary explanation

Installation space requirements

Reserve a laboratory bench area of ≥ 0.8 m ² (including supporting operating space);

Reserve a heat dissipation space in the rear (recommended ≥ 20cm) to ensure stable operation of the instrument.

Extended accessory impact

If equipped with accessories such as an automatic sampler (such as TAS-990G), graphite furnace, or atomizer, it may result in additional weight and space occupation.

For example:

The weight of the dedicated graphite tube is about 500g per piece;

The weight of the metal sleeve glass atomizer is not disclosed (needs to be installed separately).

Note: For specific host dimensions, it is recommended to directly refer to the equipment operation manual or contact the supplier for accurate data.

Key Explanation

Model difference

Suffix identification:

F: Flame type

G: Graphite furnace type

FG: Flame+Graphite Furnace Manual Type

AFG: Flame+Graphite Furnace Automatic Type

SUPER model: higher accuracy (such as wavelength repeatability ≤ 0.05nm)

Extended functionality

Automatic sampler (such as TAS-990G) supports 60 sample grades and 8 standard sample positions

The gas flow rate adopts a mass flowmeter, which has higher accuracy than a rotor flowmeter

Operational requirements

The flame method requires an air compressor pressure of 0.2-0.3MPa and an acetylene pressure of 0.05-0.06MPa

Cooling water needs to be supplied before graphite furnace analysis, and the flow rate should be started after reaching the standard

Note: Specific parameters are subject to the equipment operation manual. Additional accessories such as atomizers and automatic samplers may require additional weight and space.
