Safety
This chapter points out the safety concept of the instrument and contains general rules of behavior
and warnings from direct and indirect hazards concerning the use of the product.
For the user's safety all safety instructions and the safety messages in the individual chapters shall
strictly be observed and followed. Therefore, the manual must always be available to all persons
performing the tasks described herein.
2 .1
User qualification
The instrument may only be used by laboratory personnel and other persons, who on account of
training and professional experience know the dangers, which can develop when operating the instru-
ment.
Untrained personnel or persons, who are currently being trained, require careful supervision by a quali-
fied person. The present Operation Manual serves as a basis for training.
2 .2
Proper use
The Encapsulator B-390 has been designed and built as laboratory instrument.
The Encapsulator B-390 is a semi-automated instrument used for the polymer encapsulation of
chemical substances, bio-molecules, drugs, flavor & fragrances, pigments, extracts, cells and micro-
organisms under open conditions. Aseptic working conditions are possible, because all parts in
contact with the encapsulation mixture are autoclavable.
The bead formation is based on the fact that a controlled, laminar liquid jet is broken into equally sized
beads, if vibrated at an optimal frequency.
The Encapsulator B-390 provides just such controlled conditions to generate beads between 0.15 to
2 mm. The instrument is ideally suited to encapsulate particles < 50 µm.
If the instrument is used with potentially toxic or hazardous substances, it has to be installed inside a
closed fume hood or glove box. In such case, the complete processing and system handling has to
be performed within the ventilated box to avoid toxication and other hazardous situations to the user
and the environment.
2 .3

Applications not mentioned in section 2.2 are considered to be improper. Applications which do not
comply with the technical data (see section 3 of this manual) are also considered to be improper.
The operator bears the sole risk for any damages or hazards caused by improper use!
The following uses are expressly forbidden:
