Subboiling acid purifier

The purity of acid is crucial in trace element and ultra trace element analysis. The higher the purity, the lower the background interference.

Commercial high-purity acids are not only expensive, but also have a decrease in purity when in contact with air.

Acid purification is an economical way to obtain high-purity acidsmethod.

Subboiling acid purifierAlso known as acid purification system or acid distillation system, it uses sub boiling technology to ensure the production of high-purity acid vapor, which is then condensed into the desired high-purity acid. It is widely used in AAS, ICP-OES, ICP-MS, AFS, and other spectroscopic analyses. Applicable toNitric acid purification (HNO3), saltAcid purification (HCl)*Purification (HF).Adhering to our motto of 'Invention&Innovation', Amerlab has launched a new acid purification system AP300 based on the highly successful AP200. AP300 retains all the technologies applied in AP200, while adding multiple more efficient, secure, and user-friendly technologies. With outstanding performance, AP300 redefines acid purification systems.

Real temperature control（RTC)

• Subboiling acid purifier AP300ofWenThe temperature sensor has undergone special processing to achieve the same corrosion resistance as polytetrafluoroethylene (PTFE) material.

• Therefore, it can be immersed in acid solution to directly measure the true temperature of the acid solution, rather than measuring the temperature of the heater.

• Accurate temperature control ensures the accuracy of temperature control, thereby ensuring that the acid solution is truly in a stable sub boiling state during the purification process, and the temperature does not fluctuate rapidly, further ensuring the high purity of the acid vapor.

Non contact liquid level control

Three non-contact liquid level sensors monitor the liquid levels of raw acid and purified acid in real-time. Once the liquid level of the raw acid is too low or the liquid level of the purified acid is too high, the system will immediately stop running to avoid burning dry or overflowing. The third sensor will prevent the pump from adding too much acid to the purifier.

No need to put it in the fume hood anymore

Traditionally, both purification chambers and collection bottles require an exhaust port to maintain internal gas pressure balance, inevitably leading to acid vapor leakage.

Amerlab AP300 Subboiling Acid Purifier from the United States，The use of a high-performance acid tail gas absorber effectively eliminates this problem - with an absorption efficiency of over 99% and an adsorption capacity of 50%.

More productive

Up to 70 mL/hr

Excessive temperature can cause a sharp decrease in purity. Low temperatures can lead to unbearable low yields.

Thanks to RTC technology and *'s structural design,Amerlab AP300 Subboiling Acid Purification Instrument from the United States，Capable of accurately and reasonably controlling temperature, and achieving a good balance between efficiency and effectiveness.

PTC semiconductor heater

The maximum temperature of PTC heater is determined by its own material. The higher the temperature, the lower the heating power automatically. When it reaches its critical temperature (maximum temperature), the heating power will decrease to zero (stop heating). Therefore, you don't need to worry about it overheating or even catching fire. The maximum temperature of the PTC heater we manufacture is 250 ℃ (482 ° F), which is compatible with the temperature resistance range of PTFE polytetrafluoroethylene material. In this case, even if all temperature control measures fail, the maximum temperature of the PTC heater will not exceed 250 ℃, which will not damage the PTFE cleaning chamber, thus avoiding equipment damage or fire hazards.
