3.3 Racks
Introduction
The Syncore product line allows various racks to be used
on a given platform. These permit the parallel processing
of ...
• in synthesis: 24 and 96 samples with working volum
ranging from 1 to 40ml
• in evaporation: 4 to 96 samples with working volume
ranging from 1 to 500ml
• in concentration: 4 to 12 samples with a working volume
of up to 500ml resp. 120ml
In addition, within any given format (4, 6, 12, 24, or 96),
racks can be adapted to accommodate customer ves-
sels.
All racks are heated by a heating system built into the base
plate of the unit. The heat is transferred into the samples
by means of:
• Direct transfer between the sample glass and the
metal of the rack (Racks R-12, R-24 and R-96).By
adding 1-2ml of dest. water into the racks the
evaporation can be accelerated.
• Indirect transfer between the sample glass and the me-
talshell of the rack (Racks R-6 and R-4, using a layer
of water): Hybrid heating.
Installation of a rack
The base plate and the floor of the rack must be clean before
installing a rack on the Syncore single platform. Switch the
vortex drive OFF and flip up the protective shield.
The base plate and the floor of the rack must not be fou-
led with hard particles. Particles of glass, metal, plastic,
ceramics, or similar materials can cause scratches on the
base plate or the floor of the rack. A poor contact between
the base plate and the floor of the rack detracts from the
heat transfer.
The racks are held and positioned by two corner brackets
a (with spring-loaded clamps b). Warning: Never use a
rack on the base plate if the corner brackets or the clamping
springs are missing or have become damaged.
To put a rack in place, hold it by the handles with both
your hands. Place the rack on the base plate so that the
corners of the rack floor lie on the corresponding corners
of the base plate.
Check that the floor of the rack lies in full contact on the
base plate and that the spring-loaded brackets hold the
rack fast from two sides. Finally, tighten the two screws
by hand.
