LIFE CRITICAL: Low flow calibration at 21 degrees centigrade using LASER REFRACTOMETRY ensures un-paralleled accuracy of anesthetic vapor delivery throughout the dial percentage range. Brass and specific alloy materials assure accurate HEAT TRANSFERENCE which is CRITICAL to control anesthetic agent VAPORIZATION. The internal ADVANCED WICKING system assures linear vapor delivery during EXTENDED surgical procedures. SPECIFICATIONS Weight: 15.75 lbs / 7.14 kg Height: 7 in / 177.8 mm Depth: 8 in / 203.2 mm Width: 12 in / 304.8 mm Agent Capacity: 250 ml Wicking Capacity: 75 ml External and internal parts are machined from BRASS and SPECIFIC ALLOYS, which are proven NOT to react with anesthetic agents, which has been identified to be a corrosion problem with certain aluminum and plastic materials. The liquid holding sump machined from one solid piece of BRASS assures many years of SAFE LEAK PROOF performance. STAINLESS STEEL cagemounts ensure durability over many years and procedures. The ONE PIECE FILLING SYSTEM simplifies the filling process and eases agent level monitoring during procedures. Proudly machined, assembled, and calibrated in th
