Agitador VWR 200 Rocking Platform

VWR Model 200 Rocking Platform Shaker, a benchtop rocker used to provide gentle, reproducible agitation for blotted membranes, gels, staining and destaining, hybridization, cell culture and general sample mixing. The unit rocks a flat platform through an adjustable tilt to create a slow wave action across the vessel, and is designed for continuous duty at room temperature as well as in cold rooms or heated chambers. The manufacturer's published specifications for the Model 200 list a variable speed range of 4 to 160 tilts per minute, an adjustable tilt range of approximately +/- 20 degrees, a 14 x 11 in platform and a maximum balanced load of about 7 kg (15.4 lb). Speed is set from a single analog knob on the front panel marked Speed [rpm] with an Off position and settings 1 through 9. The nameplate on the rear of the drive housing reads Model 200, Serial No. 14MO31OG, 120 Volts, 4 Amp, 60 Hz, Made in USA. The unit is fitted with an attached three-prong North American line cord and a ribbed non-slip platform mat over the stainless platform frame; the photos show the unit as a free-standing benchtop instrument with a single platform tier installed. The platform mat shows staining and general cosmetic wear consistent with laboratory use. No functional testing information was recorded and no additional platforms, posts or accessories are shown in the photos.
