MDF-1156/1156ATN

Ideal for long term preservation of biologicals, blood components and various

cell line, SANYO preservation systems employ microprocessor control to

maintain a high-precision temperature environment. They are not affected by

ambient temperature, minimizing uneven temperature distribution within the

chamber, and a temperature rise during door opening.

Why Freeze to –152˚C?

Recrystallization Mechanism (Artist’s Concept)

World’s lowest –152˚C freezer

ensures stable cell and tissue

preservation

An important factor to consider when

preserving cells or tissue at ultra-low

temperatures is to prevent amorphous ice

crystals from recrystallizing within and

outside the cells. Samples that are

maintained in an ultra-low temperature

freezer at –152˚C which is far lower than the

recrystallization point (–130˚C for pure water)

can be preserved semi-permanently.

Preservation at ultra-low temperatures

maintains vitrification without crystallization

occurring inside and outside cells.

In contrast to conventional liquid nitrogen

preservation containers, freezer preservation

has numerous advantages: no sample

contamination, no sudden liquid eruptions,

as well as low operational costs.

SANYO’s MDF-1156 and 1156ATN make

long-term storage below the recrystallization

point easier and more stable than ever

before. Built-In Temperature & Power

Failure Alarms (Lamp/Buzzer)

In case of power failure or an irregular rise in

temperature, a rechargeable battery-operat-

ed indicator lamp and alarm will be activat-

ed. A compact recording unit which auto-

matically records the inside temperature,

and a backup system with liquefied CO2 or

N2 which is selfactivated when a power out-

age occurs are also available separately. This

equipment helps insure that the contents

will be protected in the event of any power

failure or mechanical trouble.

Standard casters and levelling feet

Standard-equipped heavy duty casters make

it easy to move a freezer when necessary.

The levelling feet keep a freezer level and

firm on the floor.

Self-diagnostic function

The temperature sensor, filter sensor and

cascade sensor monitor operation conditions

continuously. Should abnormality be picked

up, an error code and the current tempera-

ture will be displayed in turn.

Ring back function

The alarm buzzer can be silenced by press-

ing the BUZZER key on the control panel.

(The remote alarm signal is not cancelled.)

Should the alarm condition continue after a

certain suspension, the alarm buzzer sound

will resume.

Easy Maintenance (MDF-193/193AT have

no filters)

Filter check lamp notifys

the user of a clogged

condenser filter.The

condenser filter is situat-

ed at the front panel to

make filter removing

and cleaning easier.

Note: The position of the filter check lamp is shown

on the control panel (see photo shown at the

bottom of this page).

Specially designed compressor and

cascade refrigeration system

Specially designed

for rugged ultra-low

temperature

applications in a

laboratory

environment (HFC

refrigerants only).

Micro-processor Temperature

Control with LED Digital Display

Extremely accurate, easy-to-read display.

The temperature inside the freezer can be

set and monitored easily by means of a

microprocessor temperature control with an

LED digital display. The thermostat

incorporates a platinum resistor (Pt. 100Ω),

precision and durability.

Integrated Cabinet Design

High-performance refrigeration system with

foamed-in-place cabinet insulation

maximizes interior temperature uniformity

and protects against fluctuating ambient

temperatures.

Hot line for secure sealing

Moisture condensation at the top edges of

the cabinet due to differences in tempera-

ture inside and out causes frost and icing

problems that may reduce heat insulation

efficiency and obstruct door movements.

These problems are prevented by the “hot

line” by means of which hot gas from the

higher temperature circuit is circulated

through the problem areas.
