ENVIRONMENTAL SCIENCES LABORATORY (LCA)

The Environmental Science Laboratory (LCA) is a support infrastructure dedicated to the preparation and chemical manipulation of environmental samples for studies conducted in the beamlines of Sirius. Classified as Biosafety Level 1 (BSL-1), the laboratory is equipped with specialized facilities to fulfill different analytical and experimental demands.

Located in the Axis 38, near to the Carnaúba beamline, the LCA features advanced equipment for environmental simulations, plant cultivation, soil and rock manipulation, cryopreservation, and microbiological studies focused on environmental research.

FACILITIES

ENVIRONMENTAL SCIENCES LABORATORY

The main area of the LCA is a chemical laboratory designed for handling and preparing environmental samples, such as fossils, plants, soils, rocks, among others. This area disposes of supplies and infrastructure for chemical manipulation, plant cultivation, and film preparation. For this, the LCA is equipped with:

  • Fume hoods for exhaustion equipped with different gas lines (N2, Air, compressed air);
  • Plant growth chamber with atmosphere and humidity control, and lighting cycles for day and night simulation;
  • Heating (muffle up to 1200°C, general purpose oven up to 250°C, and microwave oven);
  • Ultra pure water purifier;
  • Ultra water purifier;
  • Baths (ultrasonic and dry bath);
  • Stirrers/separators (magnetic stirrer with heating, vortex for microtubes, and mini-centrifuge);
  • Balances: analytical (0.1 mg) and precision (0.01 g);
  • Autoclave;
  • Spincoater;
  • Stereo microscope
  • High precision hotplate;
  • UV-Vis spectrometer
  • Radiometer (254, 312 and 365 nm);

 

Environment for chemical manipulations

POROUS MATERIALS ANALYSIS LABORATORY

The Porous Materials Analysis Laboratory (LAMP) is dedicated to the soils and rock samples preparation for studying in the Sirius beamlines. The LAMP main purpose is being a facility for understanding the soil compaction dynamics, porosity, water retention and extraction, under different pressure conditions. For this, LAMP is equipped with:

  • Pressure chamber (0 to 15 bar);
  • KSAT – saturated hydraulic conductivity
  • General purpose oven (room temperature +5 ºC up to 250°C);
  • Precision balance (0.01 g)

BACTERIA CULTIVATION LABORATORY

The Bacterial Cultivation Laboratory (LCB) is a specialized environment for the cultivation and manipulation of environmental microorganisms, which are previously isolated from the environment and have a low degree of pathogenicity. The LCB is equipped with:

  • Biosafety cabins;
  • Cryopreservation (ultrafreezer up to -86ºC, freezer and refrigerator);
  • Vortex for microtubes;
  • Incubators: refrigerated (-10 ºC to 60°C) and non-refrigerated (10 ºC  to 60°C) ones.
