“Plug-in and Go” Laboratory Grade freezing for safe storage
of enzymes, vaccines, and other biologics. Designed
with all the features required for biomedical research and
biotechnology applications such as superior uniformity,
microprocessor control, and large, flexible storage capacity.
Additionally, items such as two access ports, casters, remote
alarm contacts, and security features (a keyed door lock and
padlock handle) are always included as standard features.
• In medical applications, SANYO MDF Series biomedical
freezers provide effective storage of life-saving vaccines as
well as samples for diagnosis.
• In biotechnology applications, they provide effective storage
of enzymes for genetic research as well as culture media,
reagents and samples for testing.
• In industrial applications, they are ideal for aging and
temperature tests on electronic components, precision
devices, and compound resins.
Features
Stable Temperature Control
Using SANYO microprocessor technology the MDF series
provides precise and uniform storage temperatures
regardless of ambient conditions, with a settable temperature
range from -20°C to -30°C in 1°C increments. Built-in alarm
and product safety functions are also provided as standard
features.
Sample Protection Functions
Digitally Adjustable Temperature Setpoint, High and Low
Temperature Alarm, Door Ajar Alarm, Remote Alarm
Contacts, and Non-Volatile Memory Backup. Both visual and
audible alarms are standard.
Quiet Operation
SANYO’s energy-efficient
refrigeration design requires
no noisy condenser fan. In
combination with low dB
level compressor, this unit is
uniquely quiet and perfect for
in-lab installations.
Easy Maintenance
Natural cooling of the unit’s condenser eliminates the need
for a condensor fan. Periodic cleaning of a filter is therefore
not required, making periodic maintenance minimal. Standard
castors and leveling feet make relocation easy.
SANYO Refrigeration
Sanyo designed and built rotary compressor offers high
performance, reliability and peace of mind. Heated mullion
under door gasket prevents frost build up.
Sample Storage Security
Standard keyed door lock and integrated
padlock hasp are standard features.
Adjustable Shelving System
Four adjustable wire shelves with over
100 pound capacity each allows for
flexible material storage configurations.

Distributed by:
Features
Stable temperature control
The MDF-U730 provides precise and
uniform storage temperatures regardless of
ambient conditions through microprocessor
temperature control.
Energy-saving operation
The specially designed rotary compressor
results in an energy-saving medical freezer
with superior cooling and quiet operation.
Improved security
Standard door lock and independent padlock
ensure extra security.
Sturdy cabinet construction with
superior insulation
The integral foamed cabinet structure is
extra strong and prevents cold air loss.
Easy maintenance
No condensing fan is required as condenser
pipes are installed on the freezer cabinet’s
outer panel sides. Natural cooling eliminates
the need of periodical cleaning.
Movable wire shelves allow free position
adjustment
