LASA AGRO 3900 Workstation

LASA AGRO 3900 – Perfect Workplace

The LASA AGRO 3900 workstation is a well-organized workplace where easy operations allow rational, systematic analyses of main nutrients and numerous trace elements without much previous knowledge of chemistry.

STEP Systems GmbH programmes the photometers especially for agricultural use. This enables evaluation in mg / 100 g soil, mg / liter substrate and mg / liter solution.

The spectrophotometer and the proven reagents with a wide variety of methods and parameters perform a unique flexibility for numerous different applications. Within a very short period of time the user has a complete nutrient analysis of the soil, substrate or fertilizer solution and can thus achieve the greatest possible agricultural yields through precise fertilization. Besides easy handling, fast execution is the outstanding characteristic of the system.

LASA AGRO 3900 Workstation

For the plant producer, long waiting periods for analysis results means an unnecessary risk: immediate knowledge about the nutritional status of the plant is the Basis of successful agriculture and creates reliability in agricultural and horticultural management.

The ideal applications for the complete LASA AGRO 3900 workstation are particularly in:

Quality laboratories of peat and substrate production
Horticultural plant production, plant propagation
Research institutes
Horticultural and agricultural schools and universities
Local government sector
Agricultural and horticultural service centres

Automatic evaluation in:

mg / 100 g soil
mg / liter substrate
mg / liter solution
no recalculation is needed

Place the prepared cuvette into the photometer and all relevant information provided on it will be immediately detected during the proven 10-fold rotation measurement. Everything is documented together with the measuring result.

Own methods with linear and non-linear calibration curves can be programmed via the spectra recording (320-1100 nm), concentration, extinction and turbidity measurement. The variable cuvette sizes of 10 to 50 mm thickness allow wide measuring ranges: from trace analysis in drinking water through the soil analysis to high concentrations in stock solutions.

Traceability starts with sampling reduce errors.
Use RFID* technology and trace your samples back to the sample location. All important information, such as the sample location, sample taker, date and time are saved on an RFID* tag on the sample bottle. And you can transfer this data to the laboratory in seconds using RFID* in the LASA AGRO 3900.

IBR+ increases the reliability of your measurement values
Lot number and expiry date information is now included on the 2D barcode, this additional information is transferred to the instrument and documented with the measurement value.

Rapid data updates
Programming of methods into a spectrophotometer has never been so easy. Simply hold the cuvette test box in front of the LASA AGRO 3900 RFID* module, wait for the signal tone and it‘s done. Measurement begins straight away with accurate evaluation data for an accurate result.

Quality assurance made easy with AQA+
QA procedures can now be easily defined and documented within the Instrument without additional software. Current batch certificates (for the purpose of GMP/GLP results documentation) can be found on the RFID* tag on the cuvette box. Thanks to this RFID* technology, all batch-specific information can be retrieved immediately on the LASA AGRO 3900 and printed out.

Data transfer is simple via USB or Ethernet
Transfer your measurement data easily via a USB stick or an Ethernet connection. The same applies for software updates. The LASA AGRO 3900 can install the most upto-date device software from our website via Ethernet, so your photometer always has the latest update.
