Models MLS-3751L/MLS-3781L are for laboratory use,
while Models MLS-3751/MLS-3781 are for medical use.
Researchers waste valuable time and energy
when limited to using a centralized building
autoclave.
Installation and maintenance of central
autoclaves are not only costly but timeconsuming. Panasonic offers two solutions:
The MLS-3781/MLS-3781L and MLS-3751/
MLS-3751L portable autoclaves are designed
for individual lab use and can be conveniently
wheeled from one lab to another. Model
MLS-3751/MLS-3751L has a low enough
profile to be stored under a lab bench when
not in use.

Surprisingly Large Chamber
Despite the compact outer dimensions of
these autoclaves, they store 8 (MLS-3751/
MLS-3751L) or 12 (MLS-3781/MLS-3781L)
1,000ml flasks. The MLS-3751/MLS-3751L has
two baskets, and the larger MLS-3781/
MLS-3781L has three.
Both Panasonic models can be easily installed
in minimal space. A swing-up lid provides
effortless access for loading and unloading
test tubes, flasks and lab instruments.

For safe use of the product, precautions and
operating instructions are given by voice
guidance.
Condition
Operation
Voice Guidance
If a safety device is activated during use and the
product stops operation, the voice guidance will
inform users of verification/inspection items. In
addition, messages urging periodic maintenance
are also provided.
Please check the water level in the front exhaust tank.
Did you check the water level in the chamber?
You have finished the setup. Press the start button to begin operation.
The lid is not completely closed.
The temperature inside the chamber is higher than the set temperature.
This is the liquid sterilization program.
Please set the sterilization temperature.
Plus a Wealth of Other Important Features
Functions for user safety and cooling
fan/exhaust level adjustment to reduce
cooling time.
Conforming to the requirements of IEC standards,
when using sterilizing liquid the temperature
when opening the cover is set to 65℃ or less. In
addition, by adding exhaust holes at several
positions on the side of the product and
positioning the standard-equipment cooling fan
under the chamber, cooing efficiency and
sterilizing efficiency are increased, so that
operating time can be reduced. Furthermore, a
constant open/close interval (with 5-step
adjustment) for the exhaust process valve enables
selection of the exhaust rate for steam inside the
chamber to enable cooling in a shorter time while
reducing exhaust time and preventing boiling
over of sterilizing liquid.
The liquid sterilization program is running.
Rough Standard of Exhaust Rate
The liquid sterilization program is finished.

Please be careful of hot steam when opening the lid.

Please check if the exhaust hose is closed or kinked.
It is time for scheduled maintenance. Please check the unit for proper operation.
A partial list of the voice guidance messages is shown.
The Voice Guidance of the product is nothing more than an auxiliary function.
For safe use of this function, please read the precautions and instructions for use in this manual.
The work conditions shown on the control panel
(temperature/pressure inside chamber, sterilizing
course, time) can be printed
out by a line thermal dot
printer for record-keeping,
management, and storage.
Handle
Newly designed handle lets users open and
close the lid easily with one hand.
Scalding
prevention guard
The conventional slide handle has been completely redesigned to develop a hand-pull system that
enables easy opening/closing by gripping with
one hand. In addition, the cover is equipped with
a scalding prevention guard to prevent scalding
due to steam.
Printing example
Microprocessor temperature control
Sterilizing temperature is controlled to within
+2℃/-0℃ of the set temperature in the range of
115℃ to 135℃.
Air vent control
Can be set to allow automatic release after
sterilizing is completed.
Equipped with 4 selectable courses and 3 customizable programs
Any of 4 courses can be selected according to the purpose of use, and 3 types
of setting values can be stored for each course according to the usage
conditions. The setting values (sterilizing temperature, sterilizing time, melting
temperature, melting time, keep warm, exhaust temperature, exhaust rate)
for each program can be easily changed for the user for easy use.
•Settable ranges are shown at right.

completed, the exhaust valve
opens and the temp. drops to

can be shortened. Suitable for
equipment that can withstand
sharp drops in pressure and for
