Lab-Line model 3520 platform shaker

Heavy duty, rheostat-based analog shaker capable of agitating gels, immunoblots or with attached platform assembly, flasks.  Fully refurbished with new bearings, belt and rebuilt Bodine brush motor.  Timer capable of up to 1 hour or constant shaking.  These instruments were built to last which is why we still see so many of them shaking on lab benches after 20-30 years of continual use.
