A Clinostat consists of a slowly revolving disk, that allows a plant placed on it to be exposed to a stimulus including light equally on all sides. This lab equipment is usually regulated by clockwork, by means of which the action of external agents including light and gravity, on growing plants may be studied or regulated.

The apparatus is useful in studying the plant response, growth and other factors due to an external stimulus. It is also popularly used in botany for studying various plants, their growth cycles and other properties.

These instruments work on the principle that plants, usually require specific amount of time, also called as the presentation time, to generate a respond to an external stimulus ie. gravity or light. Clinostats are thus, specially designed to rotate at varying speeds.

Salient Features

• These instruments are light weight and portable.
• Provided with rotating and static disks.
• Adjustable rotational speed.

Use of Clinostat
