Technical Details

Chemspeed’s EMULSIFIER AGRO deck modularity allows the user to formulate, apply and test up to 150 emulsion concentrates per day in a fully automated fashion.

EMULSIFIER dimensions:
2’350 x 950 x 1’920 mm 
(7’ 70” x 3’ 2” x 6’ 4”)

Specifications of the EMULSIFIER AGRO:

  • Overhead gravimetric dispensing of powders, liquids and viscous liquids
  • High performance mixing by shaking, stirring, and / or speed mixing
  • Heating and cooling (-50 °C to 250 °C) for e.g. forced stability testing
  • Observation of dissolution and droplet diffusion while overhead gravimetric dispensing
  • Emulsion concentrate application and testing by integrated sampling, dilution, and particle size analysis
  • Reformatting for conditioned stability testing
  • Barcode sample tracking, e.g. disposable barcoded crimp vials in 
    different sizes (5 mL, 20 mL)
  • Disposable crimp vials in different sizes for emulsion concentrate formation
  • Homogenity assessment

For the formulation optimization of emulsion and suspension concentrates, 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 transfer or continuous ingredient addition while processing a formulation in a precision vessel

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.
  • 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
  • Scraping: agitation from 20 rpm up to 200 rpm in both directions
  • Continuous feed pumps & feed vessels
  • PT100 internal and external temperature control +/-0.1 °C
  • Independent electrical and fluidic heating / cooling systems for highest accuracy  (from -50 °C to 250 °C at  +/-0.1 °C accuracy) and reflux condenser systems
  • Precision calorimetry measurement (precision calorimetric probe 1W)
  • Viscosity and rheology measurement / adjustment
  • pH measurement and control
  • Vacuum connections for degassing, extraction, evaporation
  • Different gas supplies (e.g. inert gas, air)
  • Large choice of pre-formulation vessels (magnetically stirred, shaken, heated, cooled vessels, reactors, high pressure reactors, disposable vials, etc.)
