Acid Purification by Sub-boiling Distillation - AP300S

sub-Boiling Acid Distillation System

What acid purifier does?

The purity of acid is substantially important in trace-element and ultra-trace element analysis. The higher the purity, the lower the background.

Commercial high-purity acid is not only super expensive, but the purity drops after coming in contact with air.

The acid purification process is the most economical method for high-purity acid production.

Our Acid Purifier, known as Acid Purification System or Acid Distillation System, uses the sub-boiling technique to ensure a high purity acid vapor is produced, which then condenses to the desired high-purity acid widely used in AAS, ICP-OES, ICP-MS, AFS and other spectroscopy analysis.

All New AP300S

Embracing our motto of "invention and innovation," Amerlab introduces the cutting-edge acid purification / distillation system, AP300 series, as a successor to the highly acclaimed AP200 series. Retaining the original technologies of AP200, AP300 series evolves to offer enhanced efficiency, safety, and user-friendliness, incorporating several patented technologies. With its exceptional performance, AP300 series not only upholds but redefines the standards for acid purification systems, setting a new benchmark in the industry.

Real Temperature Control (RTC)

The specially treated temperature sensor has the same corrosion resistance as PTFE material. So, it can be directly immersed into the acid to measure the real temperature of the acid liquid instead of the heater. As a result, accurate temperature control ensures that the acid liquid maintains sub-boiling temperatures during the purification process.

Excellent Performance

Can purify low-purity trace metal grade (1 ppb) to high-purity grade (10 ppt).

Entirely made of PTFE or PFA

All wetted parts are made of ultra pure PTFE or PFA, the best corrosion-resistive materials.

More Productive

Up to 70 mL/hr

Too high a temperature causes the decrease of the purity dramatically. Too low a temperature causes the unbearable low production.

Thanks to RTC technique and the state-of-the art structure design, AP300 is able to control the temperature accurately and reasonably and get the best balance between efficiency and effect.

Not Just A Purifier

Ensuring Safety Around the Clock: At Amerlab, safety remains our foremost concern, particularly in the context of a continuous 24-hour operation for acid purification/distillation systems. The AP300S meticulously incorporates comprehensive safety measures to safeguard users throughout its ceaseless operation.

PTC Semi-conductor Heater

Under the unlikely event that all temperature control systems have failed, the maximum temperature is autonomously controlled by the heater and will not exceed 482 oF which prevents damage and risk of fire.
PTC heater might be the best kind for Acid Purification/Distillation System.

Peltier Thermoelectric Cooler

AP300 uses the Peltier cooling technique to efficiently condense acid vapor. Compared with air cooling and water cooling, Peltier cooling has several advantages, such as excellent temperature stability, accurate temperature control (±1℃), water saving and no bacteria breeding.

No Need For A Hood

Traditionally, both the purification chamber and the purified acid bottle required an air vent to maintain air pressure balance, resulting in inevitable acid vapor leakage.
AP300 uses a unique high-performance acid vapor scrubber which eliminates this problem - yielding an absorbing efficiency which exceeds 99% and an adsorbing capacity of 50%.

No Dryrun, No Re-do

The non-contact liquid level sensor actively monitors the real-time level of raw acid. In the event that the acid level drops to a critical point, the system is automatically halted to prevent dry running. This proactive measure ensures the avoidance of the need for purification redo, maintaining operational integrity and efficiency.

Zero Acid Contact

Automatic acid refill, removal and cleaning with the programmable pumps.

Seperated Fill/Drain Flowpaths

Despite the cost, the system incorporates two distinct flowpaths, each equipped with its own pump for filling and draining, respectively. This design completely prevents the contamination of the clean acid flowpath by the waste acid.
