CrystalEYES
Crystallization Monitoring Sensor
Product Category: Chemical Synthesis and Crystallisation
Industry: Catalysis Chemical Synthesis and Crystallisation
Supplier: H.E.L. Group
Description
Easily Determine Solubility…
The need to study crystallization is widespread in the chemical industry due to the importance of solids as the final form of many products. H.E.L’s CrystalEYES makes it easy for chemists to determine the crystallisation and dissolution points of their solutions.
Crystal Eyes monitors and logs temperature, turbidity, and pH. The system includes a choice of probes, signal conditioning electronics, and a compact PC with preloaded software ready to use. H.E.L offers a range of probes for any scale: from a test tube (~2 ml) to a bench-scale (5 L). All probes are available in PEEK, stainless steel, or Hastelloy. Want to work at different scales?- Simply change the probe, no other changes needed to the electronics or software. The data is automatically recorded into .csv format, making it readily importable to Excel, or similar packages for analysis.
Features and Options
CrystalEYES includes:
- Temperature and turbidity probes were chosen specifically for your application
- Electronics and PC with data handling software
- pH monitoring is also available
Ease of Use:
- Insert the probes into your vessel
- Heat and cool your solution

The maximum temperature and pressure of the CrystalEYES is 200 oC and MWP is 10 bar at 25 oC
Turbidity
The CrystalEYES systems, utilize H.E.L’s proprietary turbidity sensors and WinISO Control software for accurate detection of solubility and recrystallization points. The software detects solubility and recrystallization points from sharp changes in signal and this is displayed graphically in real-time, allowing immediate interpretation.
The probes are simple in design, robust and cost-effective. The design is far more sensitive than standard turbidity and as a result, produces much more accurate results.
A Near-Infrared (NIR) source sends light through the solution and back to a detector via a mirror. Turbidity then can be measured as a function of the light intensity – as particles increase, intensity drops and turbidity increases.
Probes are constructed in hard-wearing Hastelloy for excellent chemical compatibility. The system is compact with the light source and the detector is built-in to each probe and 8 probes can be comfortably operated simultaneously on the H.E.L CrystalSCAN system. At just 5 mm in diameter, the probes can be used with the smallest of vessels.
