These gravity convection ovens are designed to meet the laboratory needs of industry, research organizations and schools. Well-crafted and versatile, they are used for drying, baking, sterilizing, evaporating, heat treating, annealing and testing. The GC series ovens are competitively priced and offer exceptional value and reliability. Cabinets are attractive and durable. Exteriors are painted light grey and have a hard, scratch-resistant hammer finish. Doors open with high-impact thermoplastic handles. Cabinets have heavy steel double-wall construction. Work space is insulated from the outer cabinet with one inch of high-density mineral wool, and interiors are made of corrosive-resistant aluminized steel. Constructed of UL and CSA recognized components. The control panel is equipped with an illuminated ON-OFF rocker switch and heat/cycle pilot light. Temperature is controlled by an automatic hydraulic or a bimetal thermostat. Energy efficient, low-watt density incoloy sheathed elements are engineered into a compact design for quick run-up and recovery times. Temperature uniformity is greatly improved by a perforated heat shield which absorbs radiant heat and distributes it more evenly. Models have temperature range to 220 degreesC (428 degreesF) Interior: 13"W x 13"D x 13"H, xterior: 15"W x 15"D x 21"H

An 11"-12" sagittally sectioned fetal pig with arteries color-coded in red, molded and sealed in a transparent, safe-to-handle liquid-filled 12 3/4" x 9" plastic tray. A comprehensive instructional guide providing supplementary information for teacher and advanced students, student guide, and reproducible test sheet.
An easy way to observe and study a large frog without dissection. The Pro-Sect system displays partially dissected, 4"-5" bullfrogs. The bullfrogs are displayed in a transparent, safe-to-handle, liquid-filled, plastic tray that is moldered and sealed. Some of the internal organs such as the liver, heart, and veins and arteries have been injected with colored latex to identify their circulatory function. A comprehensive study guide provides information to assist the teacher and students. Individual internal organs are identified on a transparent overlay for study or testing purposes.
