• Viscosity measurement is easier thanks to a controller with a digital readout switchable between speed and torque.
  
• Data on shear stress, shear rate, velocity gradients, and viscosity is accumulated easily with external DC voltage signals for speed and torque (for strip or X-Y recorders) available through an output port on the rear of the control.
  
• Operator convenience and safety is increased with cord connections between drive motors and controls to allow control placement away from hostile environments.

This new clamp provides secure, reliable, and easy support of lab equipment. The 90-Degree Clamp is designed to be easier and more user-friendly than most common laboratory clamps.

Equipment adjustments that used to take three hands, pliers, and lots of patience can now be done easily in a few seconds. The triangular knobs fit comfortably in the hand and are large enough so that hand tightening applies sufficient pressure to hold rods securely. Both knobs are located on the same side of the clamp so that switching hands or awkward hand positions during equipment adjustments are eliminated. The Heavy-Duty Clamp may be used on conventional round support rods from 1/2" to 3/4" diameter. It is especially designed for use with the new antirotational octagonal rods.
