INTRODUCTION
The Micromax microcentrifuge is a quiet, high-speed bench-top
centrifuge for medical, industrial, and scientific laboratories. The
unit can achieve centrifugal force of up to 21,000 xg, making it
ideal for sedimentation of protein precipitates and separation of
blood serum.
NOTE: The Micromax microcentrifuge is available in two versions,
ventilated and refrigerated. The parts of this manual that apply to
the refrigerated version will be identified as RF only.
The unit reaches full speed within 15 seconds, even when fully
loaded, and brakes to a stop in approximately 15 seconds. It
features a maintenance-free, brushless motor and an easy-to-use
front panel which provides three versatile modes of operation:
automatic timed run, momentary spin (pulse) and continuous
operation (hold mode). Acceleration and deceleration rates may
be controlled to optimize runs - rapid for fast separations or slow
for delicate samples. Repeat runs with precisely the same speed
and time settings may be achieved at the touch of a button.
Micromax is a variable-speed unit with a range of 1000 to 15,000
RPM. The unit accommodates lightweight, dynamically-balanced
polypropylene rotors. The rotors cannot corrode, offer excellent
acceleration and deceleration characteristics and totally contain
tubes, allowing complete sample recovery even if a tube breaks.
The 891 rotor holds up to 24 sample tubes and provides aerosol
containment for biological samples. The 851 rotor holds up to 24
x 1.5-2 mL and 24 x 0.5 mL sample tubes, the 852 rotor holds up
to 48 x 0.5 mL or 24 x Microtainer tubes and the 853 rotor holds
up to 40 x 0.25 mL/0.4 mL or 6 x 50 mm glass tubes. Also, the
851 rotor has room to accommodate screw-cap microtubes,
microtube filters, and micro spin-columns. Section 4.1 provides a
speed and force table for these rotors.
A fail-safe cover interlock ensures that the cover is closed before
a run can begin and keeps the cover closed until the rotor has
reached a safe low speed (below 150 rpm), even in the event of a
power failure.
