Labotronics Electrolyte Analyzer LB-21ELA measures K⁺, Na⁺, Cl⁻, Ca²⁺, pH, and CO₂ in whole blood, serum, plasma, and diluted urine samples. It processes up to 60 samples per hour with a sample volume of 100–150 µL and delivers results within 60 seconds. Featuring automatic calibration, a 7-inch color touchscreen, and an integrated reagent pack, it supports streamlined electrolyte testing. Its automatic waste collection system makes it suitable for veterinary laboratories and animal healthcare facilities.
