      MANTECH burets are available with 10mL and 25mL syringes, and have a resolution of roughly 100,000 steps providing precise injections down to the microliter level. Actual performance of burets and syringes are verified in MANTECH's QC process with accepted tolerances exceeding requirements of ASTM E287, and a report is provided with each new syringe. 

      Users can perform their own verification of dispense volume accuracy by navigating to Hardware>Manual Control>Buret in MANTECH Pro software.
