What are the Two Types of Laboratory Freezers?
There are two common types of laboratory freezers:
Low-temperature freezer
One is the 'Minus 20' or low-temperature freezer. Just as the name implies, their operating temperature is -20℃. This temperature makes them ideal for storing material that needs to remain frozen.
An example of a 'Minus 20' freezer is an enzyme freezer. Enzymes are used in life science research and lose key elements if not stored in a precise range. The enzyme freezer features a precise temperature control that is key when storing enzymes. This feature eliminates any warming cycles that would damage the activity of the enzymes.
Ultra-low temperature freezer
The other common type of lab freezer is the ultra-low temperature freezer also known as the ULT. These freezers are designed with either a vertical or horizontal configuration. These freezers have a stainless steel interior and multiple shelves for accessories. The storage compartment operates at a temperature of -80℃. These freezers are designed for the storage of items over a moderate to long-term time-frame.
A lab specimen freezer should be set to maintain an ultra-low temperature range, typically between -20°C to -80°C (-4°F to -112°F). The exact temperature setting may vary depending on the requirements of the stored samples and the specifications of the freezer model. It is important to follow the manufacturer's recommendations and any specific guidelines for the samples being stored.
What Specimens Need to Be Refrigerated?
The following types of specimens generally require refrigeration to maintain their quality:
Blood Samples: Whole blood, serum, and plasma samples often need to be refrigerated to prevent degradation of the components, particularly if they are not processed immediately after collection.
Cell Samples: Cells collected for genetic or molecular testing, such as buccal swabs, may need refrigeration to prevent DNA degradation.
Tissue Samples: Fresh tissue specimens for histology or molecular analysis are usually stored at 4°C (39.2°F) or colder to preserve their structure and integrity.
Bacterial Cultures: Some bacterial cultures require refrigeration to slow their growth or maintain viability.
Biological Fluids: Body fluids such as urine, cerebrospinal fluid (CSF), and synovial fluid may need refrigeration depending on the analytes being tested.
Molecular Biology Reagents: Certain reagents used in molecular biology, such as enzymes and oligonucleotides, require refrigeration to ensure their effectiveness.
Chemicals: Some chemicals and reagents used in laboratory tests need to be refrigerated to prevent decomposition or degradation.
It is important to consult the specific protocols or guidelines for each type of specimen and follow the recommended storage conditions to ensure the samples remain viable and accurate for subsequent analyses.
Types of Lab Freezers, Qualities, and Recommended Use
One of the major requirements for the successful operation of various laboratories and medical institutions is freezers. The reason is that freezers provide safe and dependable storage conditions for materials and valuable samples requiring a low-temperature environment. There are various lab freezer options to choose from, depending on the needs of a specific lab.
That implies that just as there are multiple laboratories with varying requirements, there are specific lab freezers for addressing particular needs within the medical and laboratory environments. Therefore, opting for a lab freezer that fits the bill depending on the specimens and supplies your facility handles is paramount.
Additionally, failure to hold critical biological samples at steady temperatures can compromise a timely study in research laboratories. For that reason, navigating the industry of scientific, medical, and laboratory storage can be tricky if you do not have the necessary knowledge. In that case, purchasing any freezer off the floor of a chain store may be an easy solution, but such a decision is dangerous and expensive as well.
Investing in a quality freezer engineered for the specific requirements of your lab or medical facility is not an option.
The freezer is part of the significant differences between medical or laboratory storage and household refrigeration. Most residential refrigerators indeed include a freezer compartment, but CDC strongly discourages the use of refrigerator-freezers for any form of vaccine storage. That applies to laboratory storage requirements as well.
The reason is that refrigerator-freezers do not prioritize temperature stability, whether they are compact dorm-style models or full-sized frost-free units. Also, refrigerator-freezers with single compressor units have much broader temperature gradients in the interior. That implies that they are not the best option for keeping sensitive lab samples safe.
Independent control of the temperature of each compartment is also a challenge in the case of household refrigerator-freezers. That is the other reason why they are not ideal for medical institutions. Manufacturers specializing in the storage of vaccines offer all-refrigerators or freezerless refrigerators and all-freezers instead of refrigerator-freezer units.
Refrigerator-freezer units are suitable for medical professionals who want to store ice packs, staff items, and beverages, but not vaccine storage. Additionally, storing such staff items like lunch and snacks in the same unit with vaccines is not advisable because community refrigerators experience increased traffic on various occasions.
As such, exposure to ambient temperature is high in the case of refrigerator-freezers. That can harm interior contents over time, which makes refrigerator-freezers inappropriate for labs and medical establishments. These are some of the unique lab storage requirements you cannot afford to overlook if you are focusing on successful operations.
Below are some details on various types of lab freezers that can address your requirements in the best way possible.
Qualities
If your lab handles materials that require an environment with low temperatures, you need to acquire ultra-low temperature freezers. That allows you to store such materials in temperatures below -40°C. Attaining temperatures as low as -86°C is possible through some ultra-low freezers thanks to two independent evaporator circuits surrounding the interior chamber.
You also need to note that ultra-low freezers typically use a substantial amount of energy to maintain the lowest temperatures.
Recommended Use
Ultra-low temperature freezers are ideal for the storage of materials demanding low temperatures in labs and medical establishments.
Qualities
Sufficient storage space is a priority for some labs and medical institutions. Chest freezers are larger pieces of equipment that offer substantial storage space, and they open from the top rather than the front. As is the case of most laboratory freezers, chest freezers come with alarm systems for providing alerts on locks, changes in temperature, and they display digital temperature readings too.
Chest freezers do not have shelving. So, if your laboratory requires a high level of storage organization, opting for chest freezers will not be a wise idea.
Recommended Use
Labs that must store large items within a single device should invest in chest freezers because they will serve this purpose best.
Qualities
There are various designs of under-counter freezers, including general-purpose, explosion-proof, and the flammable material storage option. You can also pick the right size and temperature range from the varieties of under-counter freezers available, and they include leveling feet too. Also, ventilation is through forced air in the case of under-counter freezers, and you do not need additional clearance space if you opt for the general-purpose model.
Provision for controlling the defrost frequency is also available, which suggests that you do not expect unplanned thaws and dehydration of samples.
Recommended Use
The ability to save on space is one of the most significant advantages of under-counter freezers because they fit comfortably under lab benches and counters. If saving on space is part of the concerns within your lab or medical facility, then, under-counter freezers will prove ideal.
Qualities
Upright freezers are probably the most common variety in various laboratories and medical institutions. These freezers open from the front, and that is why they resemble a traditional home freezer for storing groceries. The sizes of upright freezers range from the small counter-top option to large designs for storing high quantities of lab samples.
In most cases, upright freezers come with shelving units in their interior, which allow you to maximize space and organize samples without difficulties. Apart from organizational capabilities, upright freezers are also quite popular in the medical sector because of their spatial efficiency. On the other hand, upright freezers do not take up much floor space, yet, they store maximum quantities of materials due to their vertical design.
Recommended Use
If you need a freezer that maximizes temperature uniformity to promote exposure of all lab samples to the same conditions, look no further than upright freezers. That also ensures a reduction in the recovery time after opening the freezer's door.
What is the Difference Between a Sample Cabinetand a Specimen Cabinet?
A sample cabinet and a specimen cabinet are similar in function but may differ in terms of intended usage and design features.
Sample Cabinet:
A sample cabinet is a general term for a storage unit used to house various types of samples, which can include anything from industrial parts to consumer products undergoing testing. These cabinets are often found in manufacturing, quality control, or product testing environments. They typically provide a secure and organized space for storing items that need to be easily accessible for inspection, testing, or reference purposes.
Specimen Cabinet:
A specimen cabinet, on the other hand, is specifically designed for storing biological or scientific specimens. These cabinets are used in laboratories, hospitals, and research facilities to securely and properly maintain the condition of delicate samples, often requiring precise temperature and humidity controls. Specimen cabinets may offer additional features such as adjustable, lockable drawers, built-in refrigeration or freezing capabilities, and advanced sealing to prevent cross-contamination.
While both cabinets serve to store and organize items, a sample cabinet is geared towards physical samples used in manufacturing or testing settings, whereas a specimen cabinet is designed for the specialized needs of storing biological or scientific materials that require specific environmental conditions to preserve their integrity.
Slide cabinets are designed to store microscope slides, and their capacity depends on several factors such as the size of the slides, the number of trays per drawer, and the total number of drawers in the cabinet.
Typically, a standard full-size microscope slide measures about 75mm x 25mm (about 3" x 1"). The capacity of a slide cabinet is often expressed in terms of how many standard microscope slides it can hold. For example, a small cabinet might have the capacity to store a few hundred slides, while larger models can accommodate thousands of slides.
For instance, a typical 2-door, 3-drawer slide cabinet might have a capacity of around 2,000 to 3,000 standard microscope slides. However, this can vary significantly based on the specific configuration of the cabinet and the layout of its compartments.
It's important to note that when purchasing a slide cabinet, it's crucial to consider not only your current storage needs but also any potential future expansion. Some slide cabinets are modular, allowing for additional drawers or units to be added as needed.
