V.D.R.L. Rotator (Serological Shaker), which is a specialized, smaller version of the rotary shaker specifically designed for clinical diagnostics and blood bank laboratories.

While the previous model (HE-140) was a heavy-duty industrial unit, this 300 x 300 mm model is a precision benchtop instrument for delicate serological work.

The HE-142 Kahn Shaking Machine is a robust laboratory instrument designed for continuous shaking of solutions in Erlenmeyer flasks, bottles, and beakers. Unlike orbital shakers, this model provides a reciprocating (back-and-forth) linear motion, making it ideal for specialized chemical reactions, serological tests, and culture growth.

Built on a heavy-duty angle iron frame, this machine is designed for stability and long-term durability in high-traffic laboratories.

Key Features

 

• Heavy-Duty Construction: Mounted on a sturdy angle iron frame to minimize vibration and prevent "walking" during operation.

• Linear Reciprocating Motion: High-quality ball-bearing crank shafts provide a smooth horizontal stroke (approx. 1.5” to 2”).

• Precision Speed Control: Equipped with a DC Motor Drive and a continuously variable electronic speed regulator for accurate RPM management.

• Secure Holding: The platform is fitted with high-tension stainless steel springs or rubber discs to hold flasks of various sizes (50 ml to 1000 ml) securely.

• Reliable Power: Designed to operate on standard 220/230 Volts A.C. supply.

Designed for continues shaking of solutions in Erlenmeyer Flasks from 50 ml to 1000 ml capacity. It isa compact bench type table top model with platform fitted with rubber discs mounted on ball bearingcrank shafts to give an orbital motion to the flask, within a diameter of approximately 2”. and ismounted on a heavy and sturdy angle iron frame with DC Motor Drive with Continuously variableElectronic Speed Regulator To work 220/230 volts A.C. supply.

The HE-143 Wrist Action Shaker is designed to simulate the manual shaking of laboratory flasks. It features a heavy cast iron body with a rugged construction to ensure vibration-free operation. Equipped with two oscillating side arms, it provides a specialized "wrist-action" motion that is ideal for vigorous extraction, dissolution, and mixing of solutions.

This model is powered by a Fractional Horsepower (F.H.P.) Heavy Duty Motor, ensuring consistent performance even when fully loaded with large flasks.

Key Features

 

• Wrist-Action Motion: Specifically designed to provide an oscillating swirl, mimicking human hand-shaking.

• Heavy Cast Iron Base: Provides maximum stability; the machine stays firmly on the benchtop without moving.

• Side Arm Clamps: Adjustable clamps to hold Erlenmeyer flasks ranging from 100 ml to 1000 ml capacity.

• Variable Speed Control: Allows the user to adjust the shaking intensity from gentle to high-speed agitation.

• Robust Motor: High-torque F.H.P. motor designed for continuous laboratory use.
