Abstract: A gripping assembly for a fishing tool which includes first and second end members and a plurality of gripping members which are retained by the first and second end members and which are moveable between a radially expanded configuration and a radially restricted configuration by rotation of the second end member with respect to the first end member.

Abstract: An orbital shaker which provides a shaking motion that is both stable and accurate to allow repeatability is provided, which allows for ease of cleaning of the shaking platform due to its mounting on a drive platform that keeps the entire drive system in an assembled state even if the shaking platform is removed for cleaning. A vibration sensor can also be provided that senses an unbalanced load on the orbital shaker and communicates with the orbital shaker controller to reduce the shaking speed in a pre-determined, trackable manner so that shaking of samples can be continued at a vibration level that is below a threshold value. Additionally, an incubating enclosure can also be provided in which a uniform heat is created throughout the entire incubating chamber in order to assure minimum temperature fluctuations between samples being processed regardless of their position on the shaking platform.
