spray dryer b chi b 290
Spray DryerBüchi B-290

Büchi B-290 spray dryer is an equipment that enables transformation of liquid samples (solutions, nanosuspensions and suspensions, emulsions, etc) to solids. The drying can be performed from aqueous or organic solvents in an inert atmosphere with organic solvent recycling. Product size can be controlled with independent setting of liquid feed rate and atomization pressure. The machine is customized to be suitable for hot-melt technology such as spray-congealing. High performance cyclone separates the product. The quantity of produced solid may vary between few grams and a few hundred grams.

Qualities:

-drying from aqueous and organic solvents

- allows spray-congealing

- visual insight into the process

- automatic nozzle cleaning

Encapsulator Inotech IE 50R

  • The production of beads with encapsulator Inotech IE 50R is based on the principle that a laminar liquied jet is broken into equally sized droplets by a superimposed vibration. It enables encapsulation of animal and plant cells, micro-organisms, enzymes, drugs (liquid or solid), flavors and fragrances in beads or capsules. A wide range of hydrogel polymers are compatible with the Encapsulator Inotech IE 50R such as alginate, carrageen, cellulose sulphate, chitosan, gelatine and pectin.
  • single nozzle or concentric nozzle (for co-extrusion method) kit with nozzle diameter 100 – 1500 μm
  • reproducible bead formation (0,15 - 2 mm) with narrow bead size distribution
  • high cell viability doe to low shear stress during bead formation
  • short production time (50 – 3000 beads/s)
  • sterile working contitions in an avtoclavable reaction vessel (when necessary)
  • delivery of the shell/core phase by the integrated syringe pump or by air pressure (flow rates: 70-2500 ml/h)
  • appropriate for low viscous liquids

FBRM “in-line” probeMettler Toledo, FBRM C35

FBRM “in-line” probe is intended for real-time following of the technological process within the fluid-bed equipment by enabling us to assess the evolution of particle size change during specific phase of technological procedure. Probe can be used with the BX CGD 1 process equipment (Brinox). Assessment of the particle size is performed by measuring of the time of interruption of laser beam with constant circumferential speed, which gives us distribution of particle chord lenghts.

Advantages: - measurement without sample preparation; - measurement is possible in solids volume fractions as high as 70 % v/v ; - pneumatic wiper is cleaning the optical window of the probe.

Measurement range: 0.5 mm do 3 mm

sweetana grass diffusion chambers physiologic instruments usa
Sweetana - Grass diffusion chambers(Physiologic instruments, USA)

Sweetana Grass diffusion cells are used for the permeability determination of active substances through the absorption barriers – usually through the mucosa of the small intestine.

With these chambers one can determine the permeability coefficients (Papp) of substances and

monitor the electrophysiologic parameters of the tissue during the experiment.

At the Faculty of Pharmacy we have two systems of these diffusion cells from Physiologic instruments.
