Laboratory pure water installation

In most cases, the installation environment requirements for ultra pure water machines in laboratories are not very high, but it does not mean that they can be installed arbitrarily, otherwise it may lead to frequent malfunctions in the water production system.

Equipment structural characteristics

(1) Pre filtering module: a 3.2-inch color display screen that displays the operating status of each consumable component with icons. The service life and alarm information of consumables. The pre filter column is equipped with an intelligent chip to ensure correct installation and record usage time.

(2) Host: The host is equipped with a 7-inch color touch screen display, which visualizes system installation, consumables replacement, and system status through graphics and color changes. It has a multi language switchable operation interface in Chinese, English, and other languages. The operation interface comprehensively displays real-time effluent information, including water quality parameters (conductivity and temperature), system status, water tank level, and alarm information; The monitoring interface provides information on the usage status of all consumables; All information can be viewed on one screen; The dual stage reverse osmosis system achieves an ion removal rate of over 99%, ensuring high-quality and long-term stable water quality.

(3) Water intake device: The water intake handle is equipped with a 2.4-inch color display screen, which displays real-time water quality indicators (temperature, conductivity), water intake speed, water tank level, and alarm information, and can directly read various information while taking water; It has the function of taking water with a fixed amount, and there are 5 adjustable flow rates for water intake.

(4) Water storage tank: with a capacity of 35L (or 70L, 105L), PE material blow molded and inverted conical bottom; Equipped with a UV automatic sterilization module, the UV irradiation is activated at regular intervals to effectively inhibit the growth of bacterial films; It has air sterilization and filtration functions, effectively isolating CO2, bacteria, and volatile organic compounds in the air, and protecting the quality of pure water.

The tap water we use in our daily lives contains many impurities, which are not a big problem in daily applications. However, if they are used in experiments, they will affect the results. In order to avoid problems in laboratory research, a laboratory pure water system needs to be installed.

1. Confirm the installation location of the host

During the installation of the laboratory pure water system, it is necessary to first confirm the installation position of the main unit. Generally, the main unit is hung directly on the wall or placed on the table. Before installation, ensure that the power supply and sink near the main unit are very close, and the placement positions of the tap, sewer pipe, and pressure tank are all confirmed clearly.

2. Connect the water pipes

During the installation of the laboratory pure water system, it is necessary to confirm that the connections on each water pipe are correct, especially after the installation of the main unit is completed, turn off the main switch of the tap water and make a tee. After the tee is connected, leave enough water pipe length to connect it to the main unit of the laboratory pure water system for the next step.

3. Complete the overall connection

Next, connecting the pressure water storage tank and the waste water pipe is equivalent to completing the installation of the laboratory pure water system. After installation, the system should be opened for actual testing to confirm that the entire cycle is problem free, especially when every detail of the pure water system operation is in place, it means that everyone's laboratory pure water system installation is completed.

In general, the installation environment requirements for laboratory pure water machines are not particularly high. Although the installation steps of the equipment are detailed in the instruction manual, they are often overlooked, resulting in frequent system failures.

Precautions for laboratory pure water installation

In most cases, the installation environment requirements for laboratory ultrapure water machines are not very high, but it does not mean that they can be installed arbitrarily, otherwise it may lead to frequent malfunctions in the water production system. We need to pay special attention to the following aspects during installation:

1. Try to avoid excessive voltage fluctuations or strong electromagnetic interference around the instrument, especially for devices with water intake arms and remote control functions.

2. It is recommended that the distance between the water inlet and the ultrapure water machine be 1 to 2 meters to facilitate the closure of the water inlet when replacing accessories, and to avoid affecting the water production efficiency due to the long pipeline.

3. Properly place the power supply, it is recommended to place it in a concealed location not far away. If conditions permit, a waterproof cover can be added to effectively protect the power supply in case of pipeline problems or improper handling of water spraying during replacement of accessories.

4. Avoid direct sunlight from the installation location of the instrument. Direct sunlight can cause temperature rise, which not only greatly shortens the lifespan of thick and durable water pipes, but also accelerates the growth of microorganisms in the water, affecting the quality of the effluent.

Note: As the ultrapure water machine is assembled from multiple components, if some components are installed incorrectly during installation, water leakage may occur. So it is important to note that during installation, it is necessary to strictly follow the reference manual for installation. In addition, users usually do not know how to install it themselves and need to hire professional staff to do this job. They must carefully follow each step of the operation to ensure that there will be no water leakage during future use.
