What Acid Cleaner Does?

Clean labware is crucial for accurate trace metal analysis, but traditional cleaning methods like acid soaking and microwave digestion are time-consuming and leave behind residue.
Introducing the solution you've been waiting for: acid cleaning.

The acid cleaner is also known as Acid Steam/Vapor Cleaning System or Trace Cleaning System. It uses acid vapor to clean the vessels in a sealed chamber. Through a built-in temperature-control heating system, all trace metal contaminants that are soluble in acid can be safely and efficiently removed by acid vapor. The used acid will then be drained from the chamber to prevent the extracted contaminants from being reintroduced to the cleaned vessels.

Technical advantage：

REAL TEMPERATURE CONTROL(RTC)

ensures the highest purity of acid vapor

Accurate measurement is crucial for precise control.
The Teflon-treated sensor directly monitors the actual acid temperature in real time which ensures an ideal sub-boiling condition.
Traditional cleaners only monitor the heater’s temperature. This results in less accuracy of the measuring, less control of the acid temperature and lower purity of the acid vapor.

ONE-WAY VAPOR TECH(OWV)

ensures no secondary contamination from the waste acid

OWV ensures that the used acid is drained directly from the system so there is no reflux into the acid  reservoir risking contamination. In traditional techniques, the waste acid will repeatedly reflux into the acid reservoir and evaporate. As a result, the waste acid constantly contaminates the pure acid. The resulting vapor becomes dirtier and the cleaning efficiency is reduced. Consequently, only ppb-level results can be achieved even with trace metal grade acid.

Better Materials

1、Made of PTFE---MORE DURABLE, MORE VERSATILE

Digestion often involves HF. PTFE can resist all kinds of acids including HF & aqua regia.
There is no quartz containing ppm level metal elements that is unable to resist HF.

2、Seamless Construction---NO DEAD CORNERS & NEVER CRACK

The cleaning chamber is an integrated unibody which will withstand many decades of simultaneous hot acid and high temperature.

3、Polypropylene Chassis---CORROSION RESISTANT AND NO METAL

The chassis is welded with 8mm thick polypropylene boards. It has strong corrosion resistance. Additionally, PP material does not release metal elements into the laboratory and also does not compromise the low background in the trace element analysis laboratories.

Safer

1、PTC Heating---The Safest Heaters! No Supervision Needed

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

2、Level/pH Real-Time Monitoring---Prevents Dryrun/ Overflow/ Inadequate Neutralization

All liquids are monitored in order to prevent an ineffective cleaning problem caused by insufficient pure acid/water and the overflow problem of waste acid/water and alkali. To prevent inadequate neutralization,the instrument monitors the pH of the neutralization solution. Level and pH self-checks start upon initiation. With any problem, the user is notified and the machine shuts down.

3、Pressure Real-Time Monitoring---Ensures Sealing Against High Pressure

The PTFE pressure sensing system is customized for acid cleaning. The pressure self-check starts upon initiation. With any problem, the user is notified and the machine shuts down. This prevents leaks due to incomplete bottle capping. In addition, the sensor automatically adjusts the heater’s power to avoid excessive pressure
