Insulated Containers
Insulated containers maintain a constant temperature to help protect temperature-sensitive materials during benchtop use, short- or long-term storage, or transport. Available in a variety of types, such as polyurethane boxes, chests, coolers, and mini-coolers, insulated containers can be used for enzymes, cells, reagents, and other solutions.
Specific applications include: protection from moderate and extreme ambient temperature exposure; short-term frozen or hot storage; and controlled rate freezing (approximately -1°C/minute) for cell preservation.
Insulated containers include:
- Benchtop coolers
- Dewar bottles or flasks
- Freezing containers
- Ice buckets and pans
Insulated containers are usually used for cold items, although they can also be used with cold or hot items.
Electron Microscopy Sciences Low Form Shallow Cylindrical Dewar, 2500 mL with Full Base, 135 mm depth, 170 mm I.D.
Low form shallow dewars permit essential operations that are not practical with standard cylindrical or spherical dewars including insertion of small flasks in dewar, agitation in flask with magnetic stirrer, rapid freezing and recovery of tissue/organ specimens, and tempering of stirring rods, pestles and other small objects. The protective aluminum bases extend the full height of the dewars. Note that protected vacuum tip-off tubulations are offset to the side to minimize space between the dewar bottoms and magnetic stirrers.

Electron Microscopy Sciences Lab Grade Wide Mouth Lab Dewar, 4300 mL with full base, 178 mm O.D., 365mm height
These lab grade dewars are manufactured of borosilicate glass for liquid nitrogen service. A sturdy mesh cover facilitates a firm grip, provides a cushion against bumping and increases protection. Rated the most efficient glass dewars as a result of rigid quality control along with superior design and manufacturing features.
The weighted bases result in increased stability.
The dewars are supplied with a stopper to minimize evaporation
Evacuation tip is completely shielded for increased protection.
Efficiency is assured by rigid bakeout and evacuation to 10-5 torr or better. No pads between walls on the dewars eliminates heat transfer potential. Optional full length metal housing for added protection.
