The RMA-400 Merry Go-Round unit is designed for use with all Rayonet© Photochemical and Mini Reactor models.


EQUAL RADIATION - The RMA-400 is designed to insure equal radiation of all samples, regardless of lamp position or intensity fluxuations. All samples are rotated past the light source at a speed of 5 RPM.

MULTIPLE SAMPLE CAPACITY - Up to eight samples can be irritated at one time. Reaction vessels up to 11/16" in diameter can be used.

RELATIVE QUANTUM YIELDS - Several samples can be irritated together for the determination of Relative Yields.

VERSATILE - Constant rotation speed of 5 RPM. Sample wheels will accommodate reaction vessels from 3" to 11" long. Vessels up to 11/16" in diameter can be used. Quartz and Pyrex reaction vessels are available as optional equipment.

This takes advantage of the high intensity of the 2537A°, 3000A°, and 3500A° light sources. All samples obtain the same intensity. Different samples can be photolysis at the same time.
