Base Wells Base wells are the product of integratingboth a baseplate and a feedthrough collar. They provide the functionality of both components and replace one vacuum seal with a weld joint.They are available with radially oriented access ports in four,eight, or eighteen port configurations and are fitted with either 2-3/4 inch Del-Seal Stainless Steel Bell Jars MDC stainless steel bell jars are designed foruse with MDC baseplates,base wells and feedthrough collars.A dovetail groove in the jars base flange holds a Viton MDCfeedthrough collars are used to expandthe capabilities of...
