1. EVAPOCLEAN TM EVAPOCLEAN TM CLOSED ENVIRONMENT EVAPORATION DEVICE ACID AND SOLVENT ACID AND SOLVENTPURIFICATION SAMPLE DIGESTION ACID AND SOLVENT EVAPORATION FOR TRACES ANALYSIS CLEANING STATION PATENTED EVAPOCLEAN arise from the collaboration of the ANALAB compagny and the researchers of the NATIONAL CENTER for SCIENTIFIC RESEARCH allocated to a laboratory of the PHYSICAL Institut of the Globe of Paris

2. EVAPOCLEAN TM EVAPOCLEAN TM FIVE MAJOR ADVANTAGES OF THE EVAPOCLEAN THE EVAPOCLEAN ALLOWS YOU TO EVAPORATE SOLUTIONS totally or partially, at constant and controlled temperature, reducing possible matrix interferences, with good recoveries down to ppt levels, without external contamination. IT PRODUCES ULTRA-PURE CHEMICALS by sub-boiling distillation and greatly reduces the costs related to the purchase of sub-ppb ultra-pure reagents (HCI, HF, HNO3, HClO4, H2SO4,,NH4OH, H2O2,…) THE ACIDIC DIGESTION HOLES allow you to simultaneously solubilize several samples [up to 28 samples at a time]. THE CLEANING of elbows and containers are easily achieved without additional cleaning systems, with reduced handling of cleaning reagents. THE SYSTEM WORKING AS A CLOSED ENVIRONMENT protects your staff and your laboratory against corrosive vapors. It reduces greatly your operating costs while avoiding any investment in vapor neutralization systems, scrubbers and pumps. CLOSED ENVIRONMENT EVAPORATION DEVICE 1
