What equipment are commonly used in testing laboratories?

There are many types of experimental instruments commonly used in inspection and testing laboratories, and the experimental auxiliary instruments and utensils used in different testing fields are not the same. Solid-phase extraction instrument: It is a set of extraction instruments derived from a liquid processing platform that can automatically run solid-phase extraction methods under unattended conditions, including the activation, sample loading, cleaning, and elution steps of solid-phase extraction. The switching of samples can be divided into single-channel and multi-channel solid phase extraction instruments. Rotary Evaporator: It is a common equipment in the pharma machinery. It consists of a motor, a distillation bottle, a condenser tube, a heating pot, a sample collection bottle, etc. It is mainly used for continuous distillation of volatile solvents under reduced pressure.

Ultra-pure water machine: It uses pretreatment, reverse osmosis technology, ultra-purification treatment and post-treatment methods to almost completely remove the conductive medium in the water, and also remove the non-dissociated colloidal substances, gases and organic substances in the water. Water treatment equipment that has been removed to a very low level; also known as laboratory ultrapure water devices, ultrapure water systems, ultrapure water equipment, etc. The resistivity of the ultrapure water produced should generally be greater than 10MΩ, and the resistivity of the ultrapure water should be greater than 10MΩ. Water is called ultrapure water, and the effluent resistivity of high-quality ultrapure water can reach 18.2MΩ. Microwave Digestion Apparatus: It is a commonly used sample processing instrument for the detection of inorganic heavy metals. It digests the samples by microwave heating and acid, which is completely different from the heating digestion method in an electric furnace. The operation method and principle are to weigh 0.2-1g of the sample and place it in the digestion tank. In the test solution, add about 2ML of water, add an appropriate amount of acid, usually use HCI, HF, etc., cover the tank, and put it in the furnace; the charged particles in the test solution migrate back and forth under the action of the electric field force in the alternating electromagnetic field. , will also collide with neighboring molecules, causing the sample temperature to rise. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for testing laboratories, inspection laboratories, and microbiology laboratories.

Ultrasonic oscillator is the use of high-frequency sound waves of ultrasonic waves to generate vibration, which can stir the solution, clean the utensils, and even wash clothes; when the standard type of ultrasonic cleaning machine is not suitable for a specific working environment, in addition to custom-made Ultrasonic cleaning machines with special specifications can also be equipped with a submerged vibration plate device. In the existing equipment, if there is an ordinary cleaning tank, a vibration plate device can be added to convert it into an ultrasonic cleaning machine. Constant temperature water bath oscillator: It is an instrument that combines a temperature-controlled constant temperature water bath and an oscillator. It is mainly suitable for various scientific research departments such as universities, medical care, epidemic prevention, and environmental monitoring to do biology, cells, bacteria, etc. Shaking culture of liquid and solid compounds. PH meter: It is mainly used to accurately measure the pH value of liquid medium, and it can also measure the potential value of ion electrode with the corresponding ion selective electrode.
