| "Splav - 2 " Facility
the "Splav - 2 " Facility is intended to manufacture on-borad
the spacecraft the materials by the three-dimensional and direc-
tional crystallization techniques, qaseous and liquid-phase epitaxy.
the facility is made up of technological and electric segments.
During the pre-launch ground preparation 12 metallic capsules are
installed in the technological segment inside of which there are
the quartz ampules with the materials samples. The capsules are
placed one by one into the furnace with the aid of special device.
The crystallization process is being fulfilled provided the capsule
is completely stable, the latter being extremely important factor in
microgravity.
For each capsule the technological processing mode could be
assigned, e.g. heting-up temperature, melting duration under this
temperature, cooling down rate (two different rates and the
temperature of the transfer from one rate to another might be
assigned). this data is coded on a special punch plate provided for
all capsules. the given technological mode is maintained with
high precision by he automatic control system.
In case of an experiment on-board the spacecraft the down-link
is made possible allowing to transmit back to Earth the data
related to the technological process parameters. At the same time
the on-borad registration of the micro-loads acting upon the facili-
ty is provided.

"Kashtan" Facility
The "Kashtan" Facility is designed for the separation and
purification of biologically active substance in microgravity by an
electrophoresis technique in a free stattionary state liquid. In par-
ticular, either isoelectric focal pointing or zonal elecrophoresis is
made available.
the blocomponent separation process takes place in a ter-
mostatic electrophoresis device of a special configuration allowing
to subdivide the general volume of the chamber into 49 isolated
cells. thus the stizzing of different fractions is prevented.
at the customer's request the separation process might be
registered on a photographic film. However in this case the elec-
trophoresis device is not termostatically controlled.
In case of an experiment on-board the spacecraft the down-link
is made possible allowing to transmit back to the Earth the data
related, to the technological process parameters. At the same time
the on-borad registration of the micro_loads acting upon the facili-
ty is provided.
