<:: r /> r : r >C series photochemical reactor can provide samples for analyzing reaction products and free radicals, determine reaction kinetic constants, measure quantum yield, etc., and is widely used Applied chemical synthesis, environmental protection and life sciences and other research fields. It is mainly used to study photochemical reactions under conditions such as gas phase or liquid phase media, fixed or flowing systems, ultraviolet light or simulated visible light, and whether the reaction vessel is loaded with photocatalysts. The emergence of this reactor greatly speeds up the pace of experiments, enables multiple parallel reactions, improves experimental efficiency, and effectively ensures the consistency of experimental conditions.

r : r > r : r >★ The controller of the mercury lamp power supply controls
and
the working conditions of the high-pressure mercury lamp. The power is adjustable and the operation is convenient and simple.
r : r >★ The electrical controller of the xenon lamp power supply is used to control
or
the working conditions of the xenon lamp. The power is adjustable and the operation is convenient and simple.
r : r >★ Select a mercury lamp or xenon lamp of required power in a quartz cold trap, and pass cooling water into the cold trap to remove the heat emitted by the lamp. Note that there is a thin tube at the water inlet end that leads directly to the bottom of the cold trap.
r : r >★ The effective length of the quartz cold trap is
, the thickness of the interlayer is
, and the inner diameter Ф
is
.
r : r >★ It is necessary to turn on the quartz cold trap cooling water before turning on the lights, and then turn off the cooling water after
minutes.
r : r >★ The cooling water flow rate is controlled so that the temperature of the outgoing water is lower than the incoming water.
When the cooling water is first turned on, the water flow rate should be from slow to fast to prevent the water from entering too fast. The thin water inlet pipe is broken.

r : r >★ This device is a hexahedral bracket, located between the upper and middle turntables around the quartz cold trap. Filters can be inserted as desired (to select specific wavelengths of light) and in the number (to determine the intensity of the light). A metal piece can be inserted into the position where the filter is not inserted to block the light.
