Laboratory ultrapure water machine purchasing guide: How to choose the right ultrapure water machine for the laboratory?

Laboratory ultrapure water machine is one of the indispensable equipment in the laboratory. It provides ultrapure water for scientific research experiments, chemical analysis and biotechnology applications, and plays a crucial role in the accuracy and reliability of experimental results. When purchasing laboratory ultrapure water machines, the choice should be based on the needs and actual conditions of the laboratory. The following is a guide to the purchase of laboratory ultrapure water machines, which I hope will be helpful to everyone.

First of all, before selecting a laboratory ultrapure water machine, it is necessary to clarify the water quality of the laboratory. Differences in laboratory water quality will directly affect the purchase of ultrapure water machines. Generally speaking, water quality is divided into four levels.

Secondly, the water production of the ultrapure water machine is determined based on the frequency and use of ultrapure water in the laboratory. On the one hand, the water production is related to the water quality of the laboratory, and on the other hand, it is also related to the actual needs of the laboratory. If the laboratory uses ultrapure water more frequently, the water production can be appropriately increased to meet experimental needs. In addition, you can also consider choosing an ultrapure water machine with a water reservoir, which can provide a continuous water source when there is no water or when the water consumption is large.

Third, consider the supporting equipment and functions of the ultrapure water machine. A high-quality ultrapure water machine should be able to provide a variety of supporting equipment to meet the different needs of the laboratory. For example, hot and cold water systems, ultraviolet sterilization systems, TOC detection systems, etc. The hot and cold water system can provide the required cooling water and hot water for experiments; the ultraviolet sterilization system can ensure the microbial safety of ultrapure water; and the TOC detection system can monitor organic pollutants in ultrapure water.

Fourth, consider the convenience of operation and maintenance of ultrapure water machines. The operation of the laboratory ultrapure water machine should be simple and convenient, and personnel should be proficient in operating skills in a short time. In addition, the maintenance of ultrapure water machines should also be simple and easy, and it should be better to carry out automatic cleaning and disinfection during use.

Fifth, consider the performance indicators of ultrapure water machines. It mainly includes: water quality indicators, water production, water quality stability, water storage capacity, energy consumption, etc. Water quality indicators are the core indicators of ultrapure water machines, including: conductivity, impedance, dissolved solids, dissolved oxygen, silicon, heavy metals, etc. The water production must match the needs of the laboratory, and the stability of water quality must be maintained at a high level. In addition, the water storage capacity must have a certain amount of water storage to cope with emergencies.

Then, consider the price and after-sales service of ultrapure water machines. Price is a factor that must be considered and must be selected based on the funding situation of the laboratory. At the same time, to ensure that after-sales service is complete, the installation, maintenance, and other aspects of ultra-pure water machines require reliable after-sales service support.

In short, purchasing laboratory ultrapure water machines is a process that requires comprehensive consideration of multiple factors. In this process, we need to clarify the water quality of the laboratory, understand the actual needs of the laboratory, select suitable supporting equipment and functions, consider operation and maintenance convenience, pay attention to performance indicators, and consider price and after-sales service. I hope this guide can help you better choose the ultrapure water machine suitable for the laboratory.
