Versatile Incubators Meet a Wide Range of Experimental Needs with Expanded Temperature
Control Range and Enhanced Functions

Wide temperature control range from -10°C to +60°C

With a wide temperature range from -10°C to +60°C, Panasonic Cooled Incubators allow a full range of precise experiments including environmental tests to microorganism cultures and plant germination tests.

Expanded Temperature Control Range and Enhanced Functions
  • 24-hour Clock mode and Timer mode are selectable.
  • Programmable operation start date and hour
  • A program can be set to repeat for a minimum of one time to a maximum of 98 times or continuous repeat.
  • Combination of multiple programs in Join function
Precise microprocessor temperature control

Panasonic Cooled Incubators incorporate a high precision microprocessor temperature control combined with a heater PID and compressor ON-OFF system. Intuitive Operation with New LCD Display

  • Easy operability with LCD display and pop up menu
  • Operation data can be auto-recorded and graphically displayed.
  • Data can be sent to PC using optional communication interface board (MTR-480)
Programmable operation with microcomputer control

12-step repeating operation can be programmed according to the experimentation requirements by combining flexible Temperature, Light, and time control.

Light timer control [ON/OFF]

On-Off programmed timer control for standard equipped fluorescent light (15W x 1pc) is available. Optional light addition kit (MIR-L15) can add three more fluorescent lights into the chamber ceiling, giving approx. 3000 lux at 30cm below from the light sources.

With three additional fluorescent lamps
Automatic defrosting

To combat annoying frost during low temperature operatio n, MIRs provide an automatic defrost function that operates automatically at a specified time everyday.(Manual defrosting is also selectable.) Ice will accumulate at lower temperature especially for expended period of time and can be observed through the Frost Check Window.

Prevents medium from dessication (MIR-154, 254 only)

A DC fan is designed to be aimed obliquely upward to prevent direct air flow contacting samples. This reduces medium drying by approx. 50% in MIR-154, and by approx. 15% in MIR-254*.

*The sample was placed at [1] Air outlet, and [2] Air intake area, and the result was measured after operation.

Energy savings

In addition to a microprocessor-controlled high efficient heater output and compressor ON/OFF, a renewal control program and low heat-emission inner chamber fan are newly adopted incorporated to allow high energy saving operation over a wider range of ambient environments.

Environmentally conscious

Microprocessor controlled optimum control results in high energy savings and a HCFC- free foamed-in-place rigid polyurethane insulator also helps save energy.

Easy and convenient to use

The incubator are stackable(MIR-154 only), allowing for a more efficient use of laboratory space.

Meticulous design for comfortable operation

New MIRs are crafted with a comfortable rounded corner design and offer a reversible door for a choice of left- or right-hand door opening. (Reversible door is option and is unavailable for MIR-554.)

Option (MIR-154, 254 only)

• Reduced vibration To reduce the vibration of compressor for an ideal incubation environment, the compressor is separated from the chamber. 2) Recommended for researcher’s relating to crystallization of protein. The vibration of the compressor will be reduced by the detached cooling unit.

*The purpose is to reduce the vibration caused by the compressors. This will not guarantee an non-vibration environment depend on the installation.

Alarm and Security System to Protect Sample Safety

Automatic setting temperature alarm

When the chamber temperature deviates more than ±1°C to ±5°C, all digits of the digital indicator flash. 15 minutes (default) later a buzzer will sound. This system also automatically allows programmed operation or setting value changes.

Independent over-temperature protection device

This incubator incorporates an excessive temperature prevention circuit that protects experimentation materials in the rare event that a temperature abnormality does occur. This system turns off the heater and chamber fan motor when too high a temperature is detected, and turns off the compressor when too low a temperature is detected.

Programmed memory backup mechanism

Should the power source be interrupted due to power failure or other event, programmed data remains stored in memory. When the power source is restored, operation can be continued according to the predetermined program.

Automatic return buzzer switch

After an abnormality occurs, the alarm automatically switches to the ON mode, even if the operator forgets to return the alarm buzzer to the ON mode, thus ensuring safe and secure operation.

Tamper proof

A key lock function is provided so that settings may not be changed unintentionally.

Self diagnostic function

Should a malfunction occur, the location of the malfunction can be digitally indicated, allowing quick operator response.

Data acquisition system

Data acquisition software enables remote monitoring of cooled incubators.
