The VibrasorbÂ® vibration damping mount isolates sensitive analytical balances and other instruments from disturbing vibrations. Vibrations caused by nearby pumps, blenders, stirrers and other equipment are absorbed down to 13 Hz. The mount is molded of dense black and white terrazzo with a polished surface that resists scratches and chemicals. It is supported by four vibration absorbers with neoprene feet. The mount will effectively carry weights up to 35 lb.
