Freezer Monitoring

Life Science Incubator Uses Elemental Machines for Efficiency and Peace of Mind

LabCentral is a shared laboratory space designed as a launchpad for high potential life-sciences and biotech startups.

Problem

lab freezerLabCentral has numerous -20°C and -80°C freezers, refrigerators, cold rooms, incubators, and cryogenic freezers. They were monitoring the -80°C freezers with TCA-3 monitoring devices, but the rest of their equipment was not being monitored digitally. LabCentral was using the Accsense operating system for monitoring the -80° freezers, which provided helpful 24/7 notifications. However, they had issues with the TCA-3 devices failing over time and being unreliable. They were looking for a reliable solution that would provide monitoring as well as advanced reporting for all of their equipment.

Solution

 LabCentral started using Elemental Machines Element-T devices to track all of their cold storage equipment. Now they continuously monitor more than 250 assets. The power of the data has transformed the way LabCentral operates.

“We’re able to view data for equipment that wasn’t previously connected. Now we have real-time monitoring of temperature which provides us insights into equipment functionality, analysis of shared equipment usage, and the ability to detect problems, “ said Lyndsey Rissin, Sr. Manager, Lab Operations, LabCentral, Inc.

What are your options for monitoring cold storage equipment?

Guide to Freezer/Refrigerator Monitoring and Alarming

BACKGROUND

 Monitoring of cold storage is a vital requirement for many industries and applications. Biology and pharma labs can have tens of thousands of dollars of materials in cold storage that must remain cold or risk being unusable. Quality systems and federal regulations, such as 21 CFR Part 11, often require proper documentation of temperature in freezers and refrigerators. Similarly, food service and storage facilities have to keep thousands of dollars worth of food cold to ensure it doesn’t spoil and to comply with federal regulations such as the Food Safety Modernization Act (FSMA). In some cases it’s hard to even put a value on the samples stored in freezers. In the USA this year two separate fertility clinics experienced freezer failures, losing thousands of priceless embryos and eggs stored for people hoping to have babies. So what are your options for keeping valuable samples protected in cold storage?

THERMOMETERS

thermometerThermometers have been in use for hundreds of years and represent the most straightforward method for monitoring freezer and fridge temperatures. Typically a laboratory technician or other designated person visits each freezer or fridge at least twice per day and records the temperature reading from a thermometer monitoring the internal temperature. These readings are recorded in a log and can be stored for record keeping.

 

While it is easy and straightforward to read a thermometer and record the temperature, there are some other issues that might make this technique less desirable. The initial capital cost of a thermometer is very low, but don’t ignore the cost of paying people to read and record thermometer information every single day. If you have several cold storage facilities, it could take several hours per day for someone to make all these recordings. That can translate into relatively high operating costs.

 

In addition, while it’s possible to keep records by storing the log sheets, this technique is also the most thermo prossusceptible to human error. Are all of your thermometers positioned in a way that they can be easily read? Is lighting sufficient in all areas to be able to see the thermometer clearly? Manual recordings are also easy to tamper with in the case of a regulatory or liability action.



CHART RECORDERS

Chart recorders have been used for decades to keep a continuous record of freezer and refrigerator temperatures. They are reliable, fairly inexpensive, and easy to use. The charts can  be saved and filed away to keep a comprehensive record of temperature. For these reasons chart recorders have found wide usage for monitoring cold storage.

chartWhile they are reliable and easy to use chart recorders still require someone to change out the chart paper, usually on a daily or weekly basis, and to file away the chart for compliance. If you want to get more resolution into small temperature differentials you will need to use a bigger chart recorder. Another thing to consider is operating cost. Charts and pens cost money and need to be replaced. If you have dozens of chart recorders the cost of paper charts and replacement pens can really add up.

It can also be cumbersome to find a place to store all the used charts. The FDA chart prosrequires that vaccine makers, for example, keep a log of freezer temperatures for three years. That’s more than 1000 charts that must be filed away and stored for each freezer.

 

DATA LOGGERS

data loggerData Loggers are devices that measure and store temperature readings electronically. They offer continuous monitoring of freezer/fridge temperatures and can alarm when temperatures are out of specification. 

Data loggers are more expensive than manual thermometers, but they offer the advantages of continuous monitoring and storage of data. They can also be set up to alarm for out of range temperatures. The data saved by a data logger can typically be downloaded and stored using a USB memory device, or they can be connected to a local area network.

Data loggers store a lot of information that can be easily saved and retrieved for regulatory compliance. What data logger prosdata loggers typically aren’t set up to do is to alarm users remotely for out of temperature conditions. They also are typically not set up to make data available in the cloud for easy access.



WIRELESS IOT MONITORING AND ALARMING

ETWireless IoT monitoring is easy to set up with no wires or connections needed. All elements are battery operated and seamlessly connect to the internet and to a personalized data portal in the cloud. The portal allows the user to monitor equipment in real time and to receive out of temperature alerts instantaneously via email or SMS alert.

This setup eliminates uncertainty caused by human error, stores data for years, IOT proscontinuously monitors equipment and alerts designated users for out of spec conditions. Data are securely stored in the cloud and can be easily accessed for regulatory compliance. Users are also alerted to low battery conditions or connectivity issues, so no data gets lost.
