G Y C O . . . ^ k e $4*upAXH*ed cAeaiifUj, flcuJzei G Y C O H e a t i n g Jackets were developed t o fill the need for a faster and more efficient laboratory heating device. T h e y are constructed of glass cloth a n d insulated with layers of glass wool. G Y C O heating elements are made of Safeway electrical resistance heating wire, sewn directly to the inner surface of the jacket. This intimate contact of the element with the vessel to be heated permits fast, economical operation and ease of constant control of temperature. The heating element can be operated below the visible glow point causing very little oxidation of t h e heating wire and no overheating of the insulation. Therefore, t h e life of the G Y C O Heating Jacket is greatly increased.
sizes and special sizes can be made to order. They are also available in tubular units for use on columns of varying size. Since hemispherical jackets are most widely used, GYCO Jackets are standardized in that form. As a n accessory, jacket tops are available which convert any GYCO Heating Jacket into a spherical unit. These jacket tops are available with elements for extra heat requirements or without elements for insulating purposes only.

All GYCO Jackets have a built-in iron constantan thermocouple ending in an " A N " type plug for hooking up to the pyrometer of the GYCO Pyro-tran. (This plug may be removed for use with any other pyrometer of similar type.)
Listed below, are a few sizes and prices. For a complete description of all models, accessories and prices, write for our Bulletin C-100.
