Ideal Alternative to LN
2
Storage
LN
2
Storage
Until recently, liquid preservation containers
were mainly used when preserving valuable
samples over long periods of time. This
method however, involved troublesome liquid
control and the dangers of a liquid supply. In
addition, mycoplasma etc., could cause cell
and tissue contamination in liquid phase
preservation. As a solution to this problem,
demand for vapor phase preservation has
increased. In preservation with liquid nitrogen
vapor, temperatures drop to approximately
-150ºC, the same as a mechanical cryogenic
freezer’s inner cabinet temperature of -150ºC.
However, the temperature in a LN
2
system
varies by the location of the sample within the
chamber.
Maximized Storage Capacity with Smaller Footprint
Microprocessor Temperature Control With
Digital Design
Precise setting and temperature control. The temperature inside
the freezer can be set and monitored easily by means of precise
microprocessor temperature control with an LCD graphic display.
The controller utilizes a platinum sensor which is extremely
precise and durable.
Built-In Temperature & Power Failure
Alarms (Lamp/Buzzer)
• Status Alert monitors ambient and system conditions
continuously and notifies of any abnormalities before a problem
happens.
• In case of power failure or an irregular rise in temperature, a
rechargeable, Cadnica battery operated indicator lamp and alarm
will be activated.
Built-in LN
2
Backup
• The MDF-C2156VANC is equipped with LN
2
backup system as
standard to prepare for any contingency. Built-in LN2 back-up
system and is self activated when a power outage occurs. This
feature helps ensure that the contents will be protected in the
event of any power failure or mechanical trouble.
Innovative Control & Monitoring
• Graphic LCD panel with pop-up menu function on control panel
provides more visual display and allows intuitive operation.
• Data logging function records of internal temperature for one
month or one week period. The controller also records the history
of lid opening/closing (more than 2 minutes)
Easy to Operate
Overall operability and dependability are greatly enhanced
by improved design details. Highly durable hinges are used
to support the freezer door so both opening and closing are
facilitated. Door handles are equipped with a latch-locking
system.
Low-profile Design for Easier Loading
and Unloading
The chest-type design provides a stable inside temperature and a
low profile greatly facilitates loading and unloading.
Mechanical Freezer Preservation
Mechanical freezer preservation provides users with numerous
advantages: provides uniform cryogenic storage temperatures,
no worries about sample contamination, no liquid supply
problems, no danger of sudden liquid eruptions, and low
operational costs. This freezer provides easier and more stable
long-term storage below the recrystallization point than ever
before.
An Ideal Freezing Environment with
V.I.P.
®
Plus™ Design
In Ultra-Low temperature freezers, effective insulation is
extremely critical since the temperature difference between
the outside and the inner compartment can be as high as 115ºC.
V.I.P.
®
Plus™ offers superior performance in insulating properties
providing unsurpassed uniformity in the chamber- top to bottom,
side to side, front to back.
