(e;oaotruct:ion and tostivg l.aboratoiy) Of VEB Carl Zeiss? Jana. They both

60ooC0 rpm.,, as originally planned, but both work at a maxima spce of
about 501,000 rpm. 25X1

each, placed circularly around the outer hull of the "onioa?7. The larger
rotor has twelve borings of the same kind. The borings servo the purpose
of holding small containers filled with liquids to be subjected to ultra-
centrifugation. The containers were originally made from an acil-proof
synthetic matter called Igamid IDm but trials showed that this materie t
could not witix.stanc1 the centrifugal force. Containers made from harder
synthetic matter called lgairid 1A are now being tried out.
The two rotors are interchangeable. They are suspended on a shaft of
tempered spring steel which also holds the drive mechanism placed abovo
the rot.. The drive mwclanis&7 consists of three circular Sets of openings
into whic% compressed air is blown; one set sorves as a brake.
The shaft is held by a pair of conical tongs.
4. The ultra-centrifuge is to be used in conjunction with a Schlioren device
which will serve the purpose of investigating the centrifugated liquids.
This Schlieren device will be of smaller dimensions than ?.those put out by
Zeisc~ so far. Blueprints of this small-size Schlierera dovico are being
prepared.
