Lab Companion laboratory shakers available in a number of sizes and temperature ranges in bench-top and floor model designs. Unit features include dual motion (orbital and reciprocal) control; programmable time, speed, and direction control (clockwise, counterclockwise with interval settings); and digital display of speed, time, and temperature (SI and IS models). A unique shaking mechanism provides stability, long life, and virtually vibration free movement. Delay Start and Delay Stop feature allows runs to take place during evening hours. Gentle start up and stop is offered, with smooth operation even at 10 rpm. Same Start Same Stop feature makes possible synching with robotic fluid handling equipment.
