A hotplate device has a body with a platform for receiving a vessel that contains a sample to be heated. A heating element, arranged under the platform, provides heat to the platform, based on a set temperature and a measured temperature as sensed by at least one temperature sensor, proximate to the platform. A controller located in the body directs electrical power to the heating element. As a safety feature, a wireless communication feature allows a user to enter set temperature instructions from a mobile device when communication with the mobile device is enabled and established. A proximity feature, when enabled, allows the user to enter instructions only as long as the user remains in a predetermined proximity of the hotplate device.

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.
