Acid Purification System

    Many kinds of acids and reagents are widely used in daily sample treatment and analysis. However, the purification of acid and reagents remains a big problem for researchers to deal with. Many deviations and errors in analysis are caused by poor purity of acids. Because of high cost of high purity acids, or unreliable quality, it’s very difficult to meet large demand of acids in daily analysis.

Many kinds of acids and reagents are widely used in daily sample treatment and analysis. However, the purification of acid and reagents remains a big problem for researchers to deal with. Many deviations and errors in analysis are caused by poor purity of acids. Because of high cost of high purity acids, or unreliable quality, it’s very difficult to meet large demand of acids in daily analysis. Consequently, the purification and optimization of acid become the most economical and practicable way. CIF multi-functional acid purification system is a high quality purification device designed to meet researcher’s most analyzing demands. It is multi-functional system combining acid purification, digestion, acid evaporation and cleaning into one machine. It could be used for purification of acid or alkaline solutions and organic solutions and also could be used for the purpose of cleaning small vessels and acid evaporation of sample digestion. It is easy to operate and convenience in maintenance. CIF multi-functional acid purification device consists of the highest purity TFM material and PFA reagent bottle. There are no quartz or metal components on any parts contacting with acid, which absolutely ensures the high acid purity and avoid any pollution or corrosion. CIF multi-functional acid purification device is easy to operate and suitable for high purity acid production in trace and ultra-trace analysis.
Features:
    In addition to features of Electric Heating series, CIF multi-functional acid purification system has below features:

●Suitable for the purification of most acids in very high efficiency.
Real time displaying the liquid level, avoids the unit from running dry.
Sample flask is made of high purity PFA, the material of elbow tube is high purity PTFE.
The purification is completed in closed environment, no cool water, no pollution.
Multi-purpose machine includes four functions: acid purification, sample digestion, acid vaporation and vessels cleaning. It has perfect versatility and practicability.
Maximum purify 6 kinds of reagents at a time.
Elbow connecting pipe conforms to geometric design to avoid reagents backflow during purifying process. It’s a more rapid and economical way to get high purity acids.
