Debates about throwing away medicines, essentially money, due to improper storage conditions - is ever-present. We argue that debates of this nature are relevant, but we strongly believe that the solution is simple and straight forward. Here is why
Many considerations have to be made when assessing what a refrigerator or freezer for the life sciences should be capable of and feature.
Inadequate refrigerators and freezers often pose as some of the weaker links in the cold chain.
Here are some pointers as to where to focus, thereby keeping risks low and item quality high.
A refrigeration system that is not located in the storage space, does away with cold walls, allowing for better and safer use of the storage space
Designed for professional use ensures reliability, capacity and long life
Gives clear indication if temperature limits have been exceeded, providing additional security for the stored items
Customise to specific requirements. Allowing good utilisation of the storage space, improved ergonomics and high security of the stored items
Offers easy viewing allowing shortest possible door opening time
The elimination of cold walls is achieved with a ground-up approach, and results in many advantages
A Conventional refrigerator with the evaporator down the back of the storage space.
The main implication of having the evaporator down the back of the storage chamber is very localised generation of cold, often resulting in sub-zero temperatures in many places.
With this extensive emission of cold at the back of the storage chamber, it is very difficult to control which parts of the storage chamber are and aren't exposed to this intensive cold.
Ultimately you are forced to remove items from the back of the cabinet to prevent frost damage, essentially making 15-25% of the storage chamber useless. Additionally, temperature stability and uniformity is greatly impeded as it is difficult to control where and how the cold is distributed throughout.
A BioCompact II 210 refrigerator with a finned tube evaporator.
A construction with a finned tube evaporator has many advantages. The first distinguishing factor is that the evaporator is removed from the storage space. This completely eliminates cold walls in the storage space.
As a result of eliminating cold walls, the storage chamber can be utilised to its fullest.
Just as importantly, a finned tube evaporator enables forced air distribution inside the storage chamber, distributing cold air throughout - enhancing temperature stability and uniformity.
Drawers provide a clear overview of the contents ensuring items are not missed at the rear of the cabinet. This arrangement is ideal for first in/first out operations.
Effective use of storage space
Forced air circulation means BioCompact II cabinets have no cold walls. If you use drawers divided up into sections, this also helps you make sure that all the space within the cabinet is put to effective use.
Because the cabinet can be organised to meet specific requirements it provides ease of access to all stored items. Drawers can be extended fully from the cabinet.
