FORMAX SKIN CARE & SUNSCREEN

For the formulation of complex products such as hair care and colorants, Chemspeed has developed the formulation vessel / blender with individual control of temperature and mixing speeds. Additional functionality can be added such as pH measurement and vacuum.

Formulation module is a working entity consisting of 6 individually controlled, high precision formulation workstations. Each workstation with its own vessel / blender, feed vessel and syringe pump can be customized and controlled to match almost any formulation workflow.

• Up to 6 formulation vessels / blenders (150 mL volume) with independent stirring, scraping, heating and cooling.
• Up to 6 feed vessel (50 mL volume) with magnetic stirring and jacket temperature control (up to 90 °C). These can be used e.g. for the preparation of low-viscous pre-mixes.
• Easy integration of pH probes.
• An optional pump module with one piston syringe pump per vessel / blender can be added to the formulation module. The default volume of the syringe is 1 mL. The tubing connected to the external valve head of the syringe pump allows for semi-continuous substrate transfer or continuous ingredient addition while processing a formulation in a precision vessel technology.

Precision formulation vessels / blenders technical specifications:

• Stainless steel vessels / blenders, other materials are available upon request (up to 36 formulation vessels /blenders on a FORMAX robotic platform).
• Individually controlled stirring and scraping for highest mixing, dissolving, emulsification power, as well as to avoid residuals in homogenities.
  • Various stirrer designs: dissolver disk, rotor-stator etc.
  • Stirring: agitation up to 6’000 rpm or 600+ rpm at 1’000 Pa.s even during gravimetric addition of highly viscous reagents or powders.
  • The stirring performance may vary with different stiring designs and depending on product characteristics.
  • Conveniently exchangeable scrapers for maximum formulation quality (particularly recommended in emulsification processes with and non-flowing pastes).
  • Scraping: agitation from 20 rpm up to 200 rpm in both directions.
• Continuous feed pumps and feed vessels.
• PT100 internal and external temperature control +/-0.1 °C.
• Independent electrical and fluidic heating/cooling systems for highest accuracy (from -70 °C to 250 °C at +/-0.1 °C accuracy) and reflux condenser systems.
• Precision calorimetry measurement (precision calorimetric probe 1W).
• Viscosity measurement / Rheometry.
• pH measurement and control.
• Vacuum connections for degassing, extraction, evaporation.
• Different gas supplies (e.g. inert or other gases).
• Large choice of pre-formulation vessels (magnetically stirred, shaken, heated, cooled vessels, reactors, high pressure reactors, disposable vials, etc.).
