Analysis Instruments

A laboratory orbital shaker is a device used in laboratories to mix, agitate, or aerate liquids in flasks, bottles, or test tubes by moving them in a circular (orbital) motion. It is commonly used in fields such as Microbiology, Biotechnology, and Biochemistry.

Description

A laboratory orbital shaker consists of a flat platform mounted on a motorized system that moves the platform in a circular orbit at a controlled speed. Samples are placed on the platform and held with clamps, racks, or non-slip mats. When the shaker operates, the circular motion ensures uniform mixing and proper oxygen transfer in liquid cultures.

Main Components

• Platform: Flat surface that holds flasks, beakers, or tubes.

• Motor: Produces the orbital motion.

• Speed Controller: Allows adjustment of shaking speed (RPM).

• Timer (optional): Sets the duration of shaking.

• Clamps or holders: Secure the containers during operation.

Working Principle

The motor rotates an eccentric drive mechanism, causing the platform to move in a small circular orbit rather than simply rotating. This motion gently agitates the liquid, promoting even mixing and aeration without spilling.

Common Applications

• Growing microbial cultures

• Mixing chemical solutions

• Dissolving substances in liquids

• Performing enzyme reactions and incubation processes

Typical Specifications

• Speed range: 50–300 RPM (varies by model)

• Orbit diameter: 10–25 mm

• Load capacity: Up to several kilograms depending on the shaker
