Expert Advice

Do we have the possibility to spray with organic solvents?

Read more about Do we have the possibility to spray with organic solvents?

With the Mini Spray Dryer B-290 or with the Nano Spray Dryer B-90 with the Inert Loop B-295 it is possible to spray with organic solvents without risk of explosion, because the system works under inert conditions.

How can I control the outlet temperature?

Read more about How can I control the outlet temperature?

The outlet temperature is depending on the parameters inlet temperature, sample feed rate, sample concentration and aspirator rate. A change in one of those parameters will either cause the outlet temperature increase or decrease.

What is the highest possible viscosity of a sample?

Read more about What is the highest possible viscosity of a sample?

The limiting factor is the peristaltic pump. So the sample still has to be pumpable. This will be possible with a viscosity up to 300 cps with the Mini Spray Dryer B-290 or 10 cps with the Nano Spray Dryer B-90.

What is the main difference between Nano Spray Dryer B-90 and Mini Spray Dryer B-290?

Read more about What is the main difference between Nano Spray Dryer B-90 and Mini Spray Dryer B-290?

Major differences: B-90 for smaller sample quantities (mL samples, mg powder amounts), higher yields up to 90% and smaller particle sizes (submicron) B-290 is the classical spray dryer for medium laboratory sample quantities at a wide range of applications (also viscous substances and fruit juices possible). Its scale-up is more straigthforward.
