In the laboratory, there are a variety of experimental equipment and instruments. These experimental equipment will inevitably generate heat due to various factors in actual work. If the heat is not released as soon as possible, it will cause certain experimental results. At this time, the importance of the chiller equipment is highlighted. Next, I will introduce you to one of the many laboratory equipment-the application of the chiller for the atomic absorption spectrophotometer (AAS).

First of all, let's first understand the working principle of atomic absorption spectrophotometer. Atomic absorption spectrometer is a spectrometer that analyzes the constant and trace metal elements based on the effect of the atomic vapor of the ground state of the substance on the characteristic radiation absorption.

Then the graphite heating electrode needs to be cooled and protected during the working process of the atomic absorption graphite furnace. After the work is completed, the graphite tube needs to be quickly cooled to room temperature to facilitate the next sample injection analysis. At this time, for faster and more accurate To control the temperature, special cooling circulating water equipment is required to intervene to work.

Atomic absorption graphite furnaces are divided into two types: horizontal heating and vertical heating. The heating power of the horizontal heating graphite furnace is relatively large. Therefore, users who use these equipments generally choose the AC1600B 1600W cooling circulating water machine. The vertical heating graphite furnace has a higher power Small, users generally choose AC900B 900W cooling circulating water machine.

AC series small laboratory chiller

Speaking of this, it is very necessary to introduce the AC series of Tongzhou Weipu machines. The Bingling (AC) series of small chillers are the company’s veteran products, with ten years of quality, mature and reliable performance, and nearly 10,000 sets of supporting quantities for customers. Come for a good experience. This series of products have complete configurations, complete protection and alarm systems, and can meet the applications of various industries. Unique multiple optional purification water quality configuration to ensure clean water quality; with multiple detection and alarm functions, it can provide water flow alarm protection, water level alarm protection, and over-temperature alarm protection. A parallel interface can be provided to control the start and stop of the chiller through the switch signal, and output the switch value of the alarm signal. All configurations can be customized according to the specific requirements of users.

The main features of this device are as follows:

Stainless steel open bath, easy to observe the water quality, easy to clean, to avoid dirty sewage pollution of supporting equipment;

Built-in pre-filter, which can visually observe the dirty condition of the filter element and facilitate timely replacement of the filter element;

Standard water level sensor, optional water flow switch sensor, high and low temperature alarm signal output;

All stainless steel pipe fittings and water pump, optional resin filter, circulating pure water to ensure long-term stability of water quality;

The rear exhaust has good heat dissipation, and the body does not generate heat, which is energy-saving, shock-absorbing and low-noise.

This classic chiller product has not only withstood the test of the market, but has also been known and purchased by more and more users. I believe that this laboratory chiller series of Tongzhou Weipu will bring more users in the future Better industrial refrigeration experience.
