The Use Of Laboratory Condenser

​Used in distilled liquids or organic preparations for condensation or reflux. Reflux device and distillation device are commonly used in condenser experiment devices.

Cap Function Of Centrifuge Tube

​Plastic centrifuge tubes are equipped with tube caps, and the tube caps must be tightly closed to prevent liquid from leaking out.

Centrifuge Tubes Are Classified By Material

The advantage of the plastic centrifuge tube is that it is transparent or translucent, its hardness is small, and the sample can be taken out by the puncture method.

The Main Purpose Of The Alcohol Lamp

​Alcohol lamps are often used for low-temperature heating in chemical experiments. But when doing experiments that require higher temperatures such as "charcoal reduction of copper oxide", the alco...

The Material Of The Slide

It is rectangular, 76*26 mm in size, thicker and has good light transmission; the cover glass is covered on the material to avoid liquid and objective lens Contact to avoid contamination.

Target Size Of Infrared Thermometer

​Infrared thermometers can be divided into monochromatic thermometers and two-color thermometers (radiometric colorimetric thermometers) according to their principles.

Temperature Measurement Range Of Infrared Thermometer

According to the law of blackbody radiation, the change in radiant energy caused by temperature in the short-wave band of the spectrum will exceed the change in radiant energy caused by the emissiv...

The Law Of Black Body Radiation Of Infrared Thermometer

​A black body is an idealized radiator. It absorbs all wavelengths of radiant energy, without energy reflection or transmission, and its surface has an emissivity of 1.

Principle Of Infrared Thermometer

​In nature, all objects whose temperature is higher than absolute zero are constantly emitting infrared radiation energy to the surrounding space.
