Laboratories: thermometers and temperature control

Since most drugs require specific and suitable temperatures to remain in good condition, laboratory thermometers are an indispensable tool. We are dealing with sensitive and expensive preparations that require excellent preservation, from the time they are manufactured until they reach the end recipient.

In this entire chain, the pharmaceutical companies also have to comply with the limits set to preserve the medicines in order not to jeopardize the patients’ safety. You must know that both the formulation and the active ingredients of a drug can suffer irreversible changes if this fails to be done.

Laboratory thermometers: most common products

Laboratory instruments for temperature measurement: thermometers

Now that we are in context, we will explain the two types of laboratory thermometers used to control temperature properly, both for medicines and for some industrial products (glass containers, ampoules, syringes or others) that require specific refrigeration conditions. In this environment, the aim is to maintain a stable temperature between 2 °C and 8 °C. Inside refrigerators designed specifically for this purpose, adequate temperatures are achieved. However, they must be monitored using indicators and sensors to prevent any variations.

On the other hand, a thermometer is also required in laboratory equipment sterilization machines. The aim is to make sure that the process is completed correctly and without failure due to inadequate temperatures. In such environments, the important thing is to check that a high enough temperature has been reached for disinfection. This is usually around 71 °C, although it may vary depending on the material. Thus, the two thermometers perform different functions, but they have one characteristic in common – they are both adhesive. This makes their use easy and practical since they directly detect the actual temperature when adhered to the product.

Irreversible laboratory thermometers: ideal for material sterilization processes

These types of temperature indicators have dots that act as sensors and change colouras the calibrated temperature is reached or exceeded. They areirreversible because, when these degrees are reached, the label permanently changes. This guarantees whether or not the calibration temperature has been exceeded by simply looking at each thermometer, which can even be peeled off and attached to reports.

These control elements are resistant to water, oil and steam. They are ideal in processes such as sterilization of laboratory material, unassisted control of thermal processes or compliance with the cold chain in special refrigerators. They are available in different sizes and formats, from 1 to 10 levels.

Reversible thermometers or liquid crystal strips

Reversible thermometers are strips made of liquid crystal. They are flexible and adhesive and can be placed directly on the product. The reversible laboratory thermometer changes colour as the temperature varies, displaying the current temperature at all times. This type of indicator comes in handy to view the current temperature in special refrigerators and storage areas. It is also used for temperature control of samples or preparations. There are also several models, from 7 to 16 levels. Its accuracy is ±1 °C.

In short, we would like to highlight that this type of temperature indicator is key to the safe operation of the pharmaceutical industry. Therefore, you should have good laboratory instruments and a laboratory thermometer of excellent quality.
