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

Weights for Triple Beam Balance (2000g)
Weights for Triple Beam Balance (2000g)
46892

Hanging metric weights used to extend scale capacity of Ohaus 750-S0 and 750-SW metric triple-beam balances (not included). Cast iron construction has durability and long life. The set of three attachment weights includes two 1,000g weights and one 500g weight.


Calibration weights are used to measure the weight or mass of an object using a balance or scale, or to calibrate other weights or instruments. Calibration weights can be certified or uncertified. Certified weights meet strict guidelines for accuracy and can usually be recertified. Certified weights are used in labs where a high degree of accuracy and repeatability is required. Uncertified weights are used where a lower degree of accuracy is required, including student laboratories, rough weighting operations, and measuring force. Hooked and slotted weights are often used to measure pressure, torque, and tensile strength, and to demonstrate basic laws of physics. Calibration weights differ from lab weights, which are general purpose weights used to hold an object in place, similar to a paperweight.
