Top-Loading Portable Autoclaves

The importance of sterilization is essential to good laboratory practice, particularly in biotechnology, pharmaceutical and clinical laboratories. Of all sterilization methods, high pressure steam (autoclave) is the most widely used because of its efficacy, speed and reliability. The Panasonic MLS-Series top-loading autoclaves provide a safe, reliable high pressure steam sterilizing environment within a self-contained unit that is easy to use. These reliable, energy saving autoclaves are ideal for a wide range of applications.

Ergonomic Design

Panasonic has included a host of features to make this autoclave user friendly. A heat-insulating resin coating and corners are gently rounded to simplify cleaning. The control panel is mounted on top so its easier to see and use. A clip-on drainage hose and an exhaust air tank simplifies filling and emptying. The lever locking system offers additional safety.

TechnicalInspectionLow-Profile Design

The Panasonic top-loading portable Autoclave maximizes the use of available floor space, while still providing ample capacity for storage within the 14.6” chamber. The large chamber offers greater capacity, storing example load of 8-12 1,000 ml flasks.


Swing-Top Door

The door opens upwards, so no slide open space is required. This makes the 37-centimeter wide chamber easy to access, and a low-profile design is also made possible. The MLS-3781L offers 75-litre capacity with the same footprint as the MLS-3751L.

The 14.6″ (37cm) diameter wide chamber offers ample capacity. Up to four 1000ml flasks will fit easily into one sterilizing basket, for a total capacity of 8 1000ml flasks. Also, two racks holding 50 test tubes can fit into one basket. The MLR-3751L can hold up to three baskets at one time.
