Type AR

The Energy Beam Sciences exclusive AR tip represents the state of art in filament technology. This special loop was developed for applications which demand the ultimate in mechanical stability and operating life. It is particularly recommended for use in multi-user environments and teaching laboratories. Its etched taper loop configuration and unique tip geometry enhance contrast and brightness, even at low kV. We can provide the AR loop mounted on most filament bases. Whatever your application, you should see enhanced performance with the AR loop, when compared with the standard loop filament supplied by the EM equipment manufacturer.

Type Standard

Energy Beam Sciences Standard Loop Filaments are designed to conform to Original Equipment Manufacturers’ specifications across the industry. Our loop filaments are individually manufactured with careful attention to detail, maintainingtheir precise tip geometry and using superior assembly techniques and stringent quality control for consistency and dependability in even the most demanding applications. At Energy Beam Sciences, we offer cost effective, reliable solutions for these and all of your EM consumable needs.
