MOBILE AUTOCLAVE UNITS RELIABILITY & CONTROL
Personal Series In-Lab Autoclaves
SANYO MLS-Series top-loading
autoclaves are a popular method of sterilization for today’s research laboratories.
Self-contained and easy to use, these
reliable units are ideal for a wide range
of applications, including liquid culture
media preparation, labware and waste
sterilization. Designed to meet good laboratory practice criteria in biotechnology
and research laboratories, SANYO MLSSeries portable autoclaves deliver high
pressure steam with speed, efficiency and
reliability.
Small Footprint with Swing-Up Door
The door opens upwards, so no side
opening space is required. This makes the
14.56 inch (37 centimeters) wide chamber
easy to access. The MLS-3781L offers 75liter capacity with the same footprint as
the MLS-3751L (50 liters) and is only 18.8
inches wide.
Human-oriented design
SANYO has included a host of features to
make this autoclave user friendly. There is
a heat-insulating resin housing and the
corners are gently rounded. The control
panel is mounted on top so it is easier to
see and use. There is a clip-on drainage
hose and an exhaust tank that’s easy to
fill and empty, eliminating the need for
fixed plumbing.
Microprocessor Temperature Control
Sterilizing temperature is controlled by the
microprocessor to within +2°C of the
set temperature in the range of 115°C to
135°C.
Process Voice Notification
A new feature the MLS series includes is
voice notification of the system process.
Each step of the process is notified via a
pre-recorded voice message, allowing the
end user to hear the process as it is happening from across the room.
DESIGN
Optional Process Printer
(Model MLS-37PR)
Process documentation is available via an
optional built-in type thermal printer. The
printer prints out the process run results
of temperature, pressure, vs. time. Each
printout is date and time stamped for
future reference.
Double Interlocking Structure
To ensure the safe operation of this high
temperature, high-pressure autoclave, the
chamber and the open/close hand-pull
lever are controlled by a double interlock system dependent on temperature
and pressure sensors. This way, it is
impossible to open the autoclave until
temperature and pressure levels are safe.
Integrated Cool Down Fan
Included as a standard feature, the cooldown fan decreases cool down process
times significantly. This enables access to
sterilized contents much faster.
Air Vent Control
The exhaust valve release temperature
can be set to allow automatic release
after the sterilizing cycle has been
completed. The setting range is from
+0°C to 45°C above boiling point to suit
the items being sterilized (patent
pending).
CONTROL PANEL
Optional Object Temperature Sensor
(Model MLS-37SB)
Measures temperature of items in the
autoclave chamber and sets the sterilization timer accordingly. Suitable for
materials that heat up more slowly than
the chamber, such as resins. After installa
tion, the autoclave control system can be
switched between this sensor and the
main sensors.

LOAD CAPACITY
Large Chamber
Despite the compact outer dimensions
of these autoclaves, they store 8 (MLS3751L) or 12 (MLS-3781L) 1,000 ml flasks.
14.6 inch Diameter Chamber
The 14.6 inch diameter wide chamber
offers large capacity. For example, four
1000ml flasks will fit easily into one
sterilizing basket. Also, two racks holding
50 test tubes can fit into one basket. The
MLS-3751L can accommodate two steril
izing baskets, while the large-capacity
MLS-3781L can hold up to three baskets
at one time.
• Operating time varies depending on
operating conditions.
• For liquid sterilization course, the operating
time will be longer than for instrument
sterilization course.

PRE-SET PROGRAMS
These units offer a total of 12 pre-set
programs to choose from on a simpleto-operate control panel with lighted
temperature/timer indicators. They also
allow for independent programming for
users to set their own programs.
Sterilizing
For water, culture media, reagents and
other fluids. After completion and cooling
to a selected temp., air is expelled automatically through the exhaust valve.
Sterilizing temp.: 115
Timer: 1 minute to 5 hours
Exhaust temp.: 0
Sterilizing/Keep Warm
After sterilizing culture media,
reagents and other liquids, and cooling
down naturally to a selected temp., air is
expelled automatically from the exhaust
valve. High temp. prevents solidifying.
Sterilizing temp.: 115
Timer: 1 minute to 5 hours
Exhaust temp.: 0
Warming temp.: 45˚C to 60˚C.
Melting/Keep Warm
To melt or keep culture media at a fixed
temp. (This function is not for sterilizing
but prevents solidifying.)
Melting temp.: 60
Timer: 72 hours
Warming temp.: 45˚C to 60˚C
˚C to 135˚C
˚C to 45˚C.
˚C to 135˚C
˚C to 45˚C
˚C to 114˚C
14.6"
Twelve 1000ml flasks
Instrument Sterilizing
For flasks, beakers, test tubes, and other
lab instruments. When completed, the
exhaust valve opens and the temp. drops
to 100˚C. Thus, cool down period can be
shortened. Suitable for equipment that
can withstand sharp drops in pressure
and for sterilizing waste.
Sterilizing temp.: 115
˚C to 135˚C
Timer: 1 minute to 5 hours
