Random positioning machine, the Glossary

A random positioning machine, or RPM, rotates biological samples along two independent axes to change their orientation in space in complex ways and so eliminate the effect of gravity.^[1]

Clinostat

A clinostat is a device which uses rotation to negate the effects of gravitational pull on plant growth (gravitropism) and development (gravimorphism). Random positioning machine and clinostat are gravitational instruments and Laboratory equipment.

See Random positioning machine and Clinostat

Drop tube

In physics and materials science, a drop tower or drop tube is a structure used to produce a controlled period of weightlessness for an object under study. Random positioning machine and drop tube are Laboratory equipment.

Free fall machine

The free fall machine (FFM) is designed to permit the development of small biological sample such as cell cultures with a simulated effect of micro-gravity, under free fall conditions. Random positioning machine and free fall machine are Laboratory equipment.

Gravitropism

Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant in response to gravity pulling on it.

See Random positioning machine and Gravitropism

Gravity

In physics, gravity is a fundamental interaction which causes mutual attraction between all things that have mass.

See Random positioning machine and Gravity

Hypergravity

Hypergravity is defined as the condition where the force of gravity exceeds that on the surface of the Earth.

See Random positioning machine and Hypergravity

Large diameter centrifuge

The large diameter centrifuge, or LDC, is any centrifuge extending several meters, which can rotate samples to change their acceleration in space to enhance the effect of gravity. Random positioning machine and large diameter centrifuge are gravitational instruments and Laboratory equipment.

See Random positioning machine and Large diameter centrifuge

Sub-orbital spaceflight

A sub-orbital spaceflight is a spaceflight in which the spacecraft reaches outer space, but its trajectory intersects the surface of the gravitating body from which it was launched.
