1Design and Function
1.1 Design and Construction Features
The CERTOMAT®BS-1 is an easy to operate, efficient
and durable incubator shaking cabinet for universal use
in the various tasks of biological and chemical
laboratories, for example.
The basic equipment of the BS-1 includes one tray
support for shaking trays, carrying the drive unit, and
the heater. The drive consists of a motor of external
rotor type with brushless drive and a noiseless, robust
Poly-V belt-drive. Shaking drives with different orbits
are available. The orbit can be modified by our service
on site. The different shaking speeds can be adjusted
continuously. The shaker can be equipped with trays of
different size and numerous clamps, holders as well as
mounting systems of the CERTOMAT®- shaker
program.
Two large doors made of Thermo pane glass facilitate
the fixing and removing of the shaking containers or
the changing of the tray and they allow the visual
control. For incubations near and below room
temperature a refrigerating set are optionally available.
For more information concerning the equipment
configurations see below, detailed information you will
find in chapter 4 “Technical Data and Ordering
Information”. With this information you can define the
specifications of the shaking cabinet according to your
specific demands.
The incubation chamber of the cabinet is made of
stainless steel. The internal bottom is designed as a spill
tray made of stainless steel. If containers get damaged
during shaking operation this prevents spilled media
from escaping unchecked. The spill tray can be easily
removed from the incubation chamber and then
cleaned. This design also facilitates the efficient
cleaning of the shaking cabinet.
You can use the shaking cabinet on the floor or on the
table and you can stack 2 – 3 shaking cabinets. For
stacking 2 cabinets a support frame is available. That
means optimal arrangement for operation.
1.2 Available Equipment and Accessories
1.2.1 Shaking Drives
The operating terminal and the control system are
included in the panel on the right side of the cabinet.
The shaking drive is mounted below the spill tray inside
the cabinet. The drive is similar to the drive used for the
bench top shaker CERTOMAT®RM. The drive
specifications are as follows:
•Orbital motion Ø 25 mm and 50 mm
(depending on the delivered device version; can be
changed to alternate amplitude in-place at customer’s
site by authorized service representatives of Sartorius
AG).
•Shaking speeds: 40 ... 400 1/min.
•Rotation speed accuracy: max. ± 1% of final value.
•The drive has a patented, variable mass compensation.
1.2.2 Trays
Trays can be delivered with sets of fixed clamps for
Erlenmeyer flasks of different sizes (type E, F), or they
are available for individual mounting as universal trays
type EU or FU.
•Dimensions:
type E/EU: W x D about 420 x 420 mm 1)
tray type F/FU: W x D about 800 x 420 mm 1)
The universal trays can be equipped with clamps for
Erlenmeyer flasks of different sizes, hinged test tube
racks and universal mounting system. The universal
mountings allow to use various vessels, such as beakers,
bottles, or separation funnels.
1.2.3 Illumination Unit
•The BS-1 can be ordered with an optional illumination
unit comprising 5 lamps of 18 W each. Each lamp can be
switched off separately. The mounting of the
illumination unit (see point 2.3.2) as well as its activation
in the SETUP2-menu is described in point 3.3.6.
1.2.4 Grating insert
•To static incubation, e.g. in Petri dishes, a grating insert
as an option available.
The mounting of the grating insert is described in
chapter 2.3.4.
1Trays of modified design for new locking; rebuilding of
existing trays for this locking on request. Please contact
the Sartorius customer service.
