Laboratory Refrigerators –Temperature range, capacity & requirements
Laboratory Refrigerators, One of the most essential aspects of a modern lab is the lab freezer. It is vital that you choose the right freezer to ensure that you are making a good investment. You may think that choosing the right freezer is easy and only involves checking up on some samples. However, there are several other things that you will need to check before you choose one out.
When you select the right lab freezer, you can decide on how sensitive to temperature changes your samples can be. In case, you want to replace your old equipment and set up a new facility then you should follow the considerations mentioned in this article to help you choose a new freezer.
What is the range of temperature that you will require?
When you want to buy a new lab freezer, it is crucial that you check the range of temperature that the freezer will offer. In fact, the temperature range is an essential factor to consider when you want to purchase a new freezer. Some of the most common temperature ranges for a lab freezer are as follows:
- General-purpose laboratory refrigerator temperatures will range from an approx 0 to 10 oC (32 to 5 oF), Freezer ranges are 0 to -30 oC (-22 to 32 oF)
- Ultra low-temperature freezers will range from -40 to -86 oC (-40 to -122 oF)
- Cryogenic Freezers can go down to even temperatures as low as -125 oC (-193 oF)
A life science lab shall require a freezer with a temperature range from – 20 to – 40 degrees C. This will provide a safe and stable storage condition to various types of reagents or samples. A lot of freezers that are used today have a temperature display which makes them quite convenient for medical use.
What is the capacity that you will need?
The capacity of the refrigerator will be dependent directly upon the samples and tests that you need for your storage. IT will be a good way to check your external dimensions because it will allow you to place your freezer at the designated location that you want.
There are larger research facilities and institutions where you will need to keep larger units and even multiple small units in order to fulfill your storage requirements. The multiple small units can provide you with a thin layout which will result in a lower downtime. This will increase the overall efficiency of your laboratory in the long run.
What are the requirements for good ventilation?
The requirements for ventilation will vary with each model. In fact, this is one of the main questions that you need to as your own supplier before you make your purchase. This will ensure that you understand where you will place your device also. IT will depend on the type of freezer that you want to install because air is generally sourced from the freezer’s back and the top.
Generally, if you have a large cross-section area of ventilation, then your lab freezer will be more energy efficient. The inlet for the air and the outlet cannot be covered or blocked in any manner and you will need to ensure a thorough cleaning on a regular basis. In case you have any form of restrictions on the type of ventilation that you wish to keep, then you may also go for customized ventilation. In this case, the air is often forced out from the front of your freezer and hence you will not need any additional space for clearance.
Understand whether you need temperature monitoring systems
In the event that you work with samples that are sensitive to changes in temperatures, then you will need to put in devices that can record and log temperature changes accurately. These devices store data and have alarm systems that can help in alerting you in case there are any considerable changes in temperature or exceeds any preset threshold. This ensures that your samples are not spoilt.
There are a lot of additional bells or whistles which you can keep alongside your new freezer. The temperature alarm system can be visual or audible. You can have temperature chart recorders with digital key locks and a backup battery system also to ensure the smooth working of your freezer through power blackouts. There are other devices available to improve functionality.
In conclusion, it is seen that lab freezers are essential components of labs all over the world. IT is important in several different aspects of a lab’s functionality. There are several questions that have to be asked and certain considerations that need to be made before you can choose the best freezer for your lab. However, the ones mentioned in this article will be helpful and guide you in making a good investment. Hopefully, the information mentioned in this article will have helped you.

When Can You Sue For Getting Cancer?
Being diagnosed with cancer can be devastating and affect anyone at any age. Several factors, such as genetics and lifestyle, can cause it. However, cancer can also be caused by the negligence of others. In such an instance, you can sue the people responsible for causing your cancer and claim compensation for the diagnosis and any associated damages.
Determining when and who to sue for getting cancer can be a complex process. So, it’s a wise idea to hire a lawyer to get you through the process and get the compensation you deserve. The attorney can advise you on when, how, and whom to sue for getting cancer.
With that said, here’s when you can sue for getting cancer:
- Product Liability
You can sue for getting cancer from a defective product. For example, in one hair product cancer lawsuit, a claim was made that a hair straightening product was causing uterine cancer in women. The defects in the hair product increase the risk of developing uterine cancer for whoever uses it. If you think you’re in a similar situation, you can sue the manufacturers if a certain product increases your risk of developing cancer.
However, proving your case and claiming compensation can be challenging. In such a case, you must prove the defective product caused your cancer to sue the manufacturer or retailer. You’ll have to request tests on the products to prove the defect and the relationship to cancer development. The product defect has to have caused your cancer diagnosis directly. One example is when the product has excessive amounts of lead. You’ll need to hire experts or resort to government authorities to investigate the product to prove this. This way, you have a piece of solid evidence to sue the product manufacturer.
- Medical Negligence
Medical negligence is one of the most common reasons to sue for getting cancer. You could sue for medical malpractice if the doctors, healthcare facility, hospital, or other medical professionals failed to offer the standard of care causing your cancer diagnosis. For example, if the doctor failed to order necessary tests or misdiagnosed your case resulting in cancer progression, you can sue for medical negligence.
To successfully sue for medical negligence, you must prove that the medical practitioner’s actions directly caused your cancer diagnosis. You must also show that you suffered damage because of the negligent actions of the medical practitioner. By doing so, you can claim compensation for treatment of progressing cancer, lost wages if you cannot work, and pain and suffering.
- Environmental Factors
Exposure to environmental pollutants and toxins is a common risk factor for cancer. Prolonged exposure to asbestos at the workplace, radiation, and other chemicals can increase cancer risk. If you can prove your cancer was caused by exposure to a certain environmental toxin like asbestos, consider suing the company or entity responsible for the pollutants.
Suppose a company’s activities produce excessive radiation that affects the population in a specific area and results in cancer. In that case, you can sue that company for exposing you to toxins that caused the development of your cancer.
Like the previous points, you must prove your cancer was directly caused by a specific substance you were exposed to. You’ll also have to show that the exposure was from the negligence of the company or entity you’re suing. Another aspect you must consider is the entity’s knowledge of the potential risks of exposing people to the toxin or substance. Since you’ll also claim that the company or entity was negligent, expose their bad practices that contributed to the development of your cancer.
Additionally, working in a hazardous environment may expose you to substances or toxins that can increase your cancer risk. For instance, if you’re a construction worker with constant exposure to asbestos, you’ll be at risk of developing cancer. Working as a firefighter can also expose you to asbestos and other carcinogenic substances that cause cancer.
You can sue your employer for getting cancer while working in a hazardous environment. To be successful, you must prove the cancer was caused directly by exposure to a specific chemical or substance at the workplace or in the line of duty. For example, getting cancer from asbestos exposure at a construction site.
In such a suit, you’ll claim compensation for the medical expenses covering the diagnosis and treatment, lost wages, damages for the pain and suffering caused to you and your family, and other associated costs.
Conclusion Getting a cancer diagnosis because of someone else’s negligence can be traumatizing and devastating. However, you can get a little relief through compensation for the medical expenses and other related damages, such as pain and suffering. The process of suing for getting cancer can be complicated, and it’d be best to hire an experienced lawyer to handle the litigation process. An attorney can also advise on the available legal options available and the compensation to seek.
