SOLD - This clean and fully functional Barnstead/Lab-Line Thermal Rocker Platform Shaker, Model 4637 (MO# 307010), rocks to meet a variety of mixing needs. It is an excellent alternative to hybridization incubators in which blotting membranes are gently agitated in a solution at a controlled temperature. A switch allows users to operate rockers with or without heat. Transparent acrylic gable cover must be used when rockers are operated with heat. Proportional integral derivative (PID) microprocessor controls temperature with minimal overshoot. Self-resetting thermal cutout shuts down power to heaters if temperature exceeds setpoint. Temperature is displayed on a large LED readout. The unit is constructed from cold-rolled steel with powder-coated finish and the stainless steel platform has a nonskid surface that keeps samples in place.

The platform has a mat and an acrylic cover with handle. Item is sold as is without warranty expressed or implied.
