Buchi B-390 and B-395 Pro Encapsulators



The Buchi B-390 and B-395 Pro Encapsulators are systems for the immobilisation of many different 
pharmaceuticals and food ingredients. Producing uniform capsules and beads over a pre-selectable range of 0.15 
mm to 2 mm, with a spherical shape and narrow size distribution (< 5% standard deviation is possible), these 
new systems can produce up to 6,000 beads per second.

The Encapsulator B-390 is an open system which incorporates all the basic features needed for high-quality 
bead production including an electrostatic dispersion unit and stroboscopic lamp for immediate process control. 
Parameters are set on a touch screen whilst delivery of the polymer mixture is achieved through air pressure via 
a nozzle that can be heated up to 70°C, this allows the use of polymers at melting temperatures above room 
temperature. An optional concentric nozzle system enables simultaneous shell and liquid core capsule production.

The Encapsulator B-395 Pro enables bioencapsulation under sterile working conditions. An autoclavable reaction 
vessel allows controlled sterile working conditions on the bench and sample pumping is facilitated by an 
integrated syringe pump that can be calibrated and provides throughputs from 0.01 to 50mL/min with a dead 
volume of approximately 0.5mL.
