Centrifuge GT 4 / 4R Introduction and Description | 3
Introduction and Description
Characteristics
Several rotors with a wide range of tubes can be used.
The set speed is reached within seconds. The
maintenance-free induction motor ensures quiet and low-
vibration operation even at high speeds, and guarantees a
very long lifetime.
The user-friendly control panel makes it easy to preset the
speed, RCF value, running time, temperature, and running
profile (acceleration and braking curves). You can choose
between the display of speed and RCF or the entry mode.
These settings can be changed even while the centrifuge is
running.
With the help of the PULSE key , you can also centrifuge a
sample for just a few seconds, if required.
The Fisherbrand GT 4 / 4R Centrifuge is equipped with
various safety features:
• The housing and rotor chamber consists of steel plate,
the interior is made of armour steel, while the front panel
is made of high-impact resistant plastic.
• The lid is equipped with a view port and a lock.
• The lid of the centrifuge can only be opened while the
centrifuge is switched ON and the rotor has come to a
complete stop. The centrifuge cannot be started until the
lid is closed properly.
• The integrated rotor detection systems ensure that no
inadmissible speed settings can be preselected.
• Electronic imbalance recognition
• Lid emergency release: For emergencies only, e.g. during
power failures (refer to the section
Mechanical
Emergency Door Release
)
