Orbital Shakers

Lab shakers are still commonly used in many chemical and biological laboratories, even though the magnetic stirrer is preferred in certain situations. A laboratory shaker allows a number of samples to be stirred simultaneously under identical conditions, a feature that is not possible to replicate using multiple stirrer hotplates.

Lab shakers consist of a broad table or platform which is oscillated by means of an electric motor. The samples are placed either in a beaker or Erlenmeyer flask on top of the platform which is clamped around the neck, or in test tubes or vials which can be nested into an appropriate holder. Lab shakers agitate samples either through a reciprocating linear motion, backwards and forwards, or through an orbital motion. In an orbital shaker, the platform moves in a circular motion of small diameter to create a vortex effect within the samples. The orbital motion provides a swirling action on the sample which is ideal for aeration, for example. A linear shaker is more aggressive, making it ideal for applications in which reagents must be thoroughly mixed, such as extractions. Scilogex offers two sizes of orbital laboratory shaker, both of which offer a precise and easily controlled shaking motion for thorough mixing.

The orbital lab shakers from Scilogex are well designed and robust, providing a long working life even under repeated and continuous use. We offer two sizes of orbital shaker, suitable for mixing samples with a combined weight of 2.5kg and 7.5 kg respectively. A wide range of platforms is available, making them ideal for use with culture flasks, Petri dishes, Erlenmeyer flasks, bottles and other vessels. These versatile orbital laboratory shakers operate with a 10-mm diameter orbital action, with a shaking speed ranging from 100 rpm to 350 rpm. For even greater convenience, they may be operated either with a timer (capable of functioning continuously for 1199 minutes) or under continuous operation. Free software is also available for PC control and data logging.
