What is a pharmaceutical and laboratory refrigerator?

A pharmaceutical laboratory refrigerator is a specialized device designed for the safe, accurate, and stable storage of drugs, vaccines, biological samples, temperature-sensitive chemicals, and diagnostic kits. These refrigerators are specifically used in environments such as medical laboratories, pharmaceutical centers, pharmacies, hospitals, and vaccination centers.

Temperature range of pharmaceutical laboratory refrigerator

The standard temperature range for a pharmaceutical and laboratory refrigerator is usually between:

2 to 8 degrees Celsius (°C)

This temperature range is recommended by international organizations such as WHO, FDA, and GSP for the safe storage of most drugs, vaccines, biological materials, and sensitive samples.

Why is the temperature range of 2 to 8 degrees important?

• At temperatures below 2 degrees: Medicines and vaccines may freeze and their chemical or biological structure may be damaged. For example, vaccines often become unusable after freezing.

• At temperatures above 8 degrees: Enzymatic or bacterial activities may be activated, causing spoilage or reducing the effectiveness of the drug.

Cooling system in laboratory refrigerator

The cooling system in pharmaceutical laboratory refrigerators is one of the most critical parts, as its main task is to maintain a stable, uniform and reliable temperature between 2 and 8 ° C. This system is specially designed to provide the accuracy and performance required for the storage of drugs, vaccines, biological samples and sensitive materials.

Next, we will examine the structure and components of the pharmaceutical refrigerator cooling system in detail:

Main components of the pharmaceutical laboratory refrigerator cooling system:

1. Compressor

• It is the heart of the cooling system.

• Its job is to compress the refrigerant gas and transport it to the condenser for cooling.

• Advanced models use silent and energy-efficient compressors.

2. Condenser

• It converts hot gas into liquid and expels heat.

• It is usually located on the back or bottom of the device.

• Equipped with a cooling fan to increase efficiency in industrial models.

3. Evaporator

• The coolant evaporates in this section and absorbs the heat inside the refrigerator.

• This same process reduces the internal temperature of the cabin.

4. Refrigerant Gas

• Safe and environmentally friendly gases such as R134a or R600a are commonly used in these devices.

• The choice of gas type is based on efficiency, sustainability, and environmental requirements.

5. Air Circulation Fan

• It is used to evenly circulate cold air inside the cabin.

• Prevents hot or cold spots and ensures uniform temperature.

6. Thermal insulation

• The walls are made of insulation to minimize heat exchange with the environment.

• It saves energy and maintains temperature stability.

Types of cooling systems in pharmaceutical refrigerators

1. Direct Cooling System

• Cooling through direct contact of the evaporator with the interior space

• Cheaper but may cause cold spots

• Usually without an internal fan or with limited air circulation

2. Forced-Air Cooling System

• Has a fan for uniform air circulation throughout the interior.

• More stable and uniform temperature

• Suitable for storing sensitive medicines and vaccines

Advanced refrigerators like FG models use a forced air circulation system.

Benefits of a professional cooling system in a pharmaceutical refrigerator

• High temperature stability (±0.5°C)

• Optimal energy consumption

• Continuous operation without frost (No-Frost)

• Quick response to temperature changes when the door is opened

• Increasing the shelf life of medicines and samples

Warnings and controls

In addition to the cooling system, temperature sensors and alarms play a complementary role:

• If the temperature goes outside the allowed range, an audible alarm is activated.

• In some models (such as FG refrigerators), alerts are also sent via SMS or email.

Application of pharmaceutical laboratory refrigerator

1. Storage of temperature-sensitive medications

• Many medications, such as insulin, injectable antibiotics, serums, and therapeutic solutions, should be stored at temperatures between 2 and 8°C.

• A pharmaceutical refrigerator prevents drug spoilage and maintains its effectiveness by controlling the temperature precisely.

2. Vaccine storage

• Vaccines such as influenza, hepatitis, HPV, coronavirus vaccine, etc. must be stored under specific temperature conditions.

• The slightest temperature fluctuation can reduce the effectiveness or completely destroy the vaccine.

• Pharmaceutical refrigerators with alarm systems, data logging, and uniform air circulation are ideal options for vaccine storage.

3. Storage of biological samples in laboratories

• Samples such as serum, plasma, blood, tissues, culture media, and enzymes require stable temperatures.

• A laboratory refrigerator provides standard conditions for storing these samples so that no degradation or chemical changes occur during the testing and diagnosis process.

4. Use in blood banks and blood transfusion centers

• For storing whole blood, plasma, red blood cells and blood derivatives

• The ideal temperature for blood is often 4 degrees, and the refrigerator must have precise control capabilities, power outage alarms, and 24-hour data logging.

5. Storage of diagnostic kits and biological materials

• PCR kits, antibodies, proteins, genetic material (DNA/RNA), and many sensitive reagents must be stored at a constant temperature.

• A pharmaceutical refrigerator with uniform air circulation and a No-Frost system is the best option for these materials.

6. Use in pharmacies and pharmaceutical warehouses

• Safe storage of medicines and vaccines in pharmacies and drug distribution centers

• Compliance with GSP (Good Storage Practice) standards and Ministry of Health guidelines

• Providing a temperature log for legal inspections

7. Use in hospitals and ICUs

• Storing emergency medications, ampoules, insulin, and injectables in intensive care units, emergency rooms, and operating rooms

• Safety locks, door open alarms, and batteries are essential features of these parts.

8. Application in emergency vehicles and mobile clinics

• Portable models of pharmaceutical refrigerators are used to safely transport vaccines, insulin, and medications on field missions.

• These models can be connected to car power or battery.

9. Application in pharmaceutical industries and vaccine manufacturing companies

• Storage of produced samples, raw materials, semi-finished products

• Supports data logging system, temperature alarm, connection to central quality control system (SCADA)

10. Application in research centers and universities

• Storage of biochemical compounds, experimental media, genetic materials, and laboratory specimens

• High temperature stability for repeatable and reliable research

Features of the smart pharmaceutical laboratory refrigerator

1. Smart digital controller

• Maintaining accurate and stable temperature (usually between 2 and 8 degrees)

Important tips for choosing and purchasing a pharmaceutical laboratory refrigerator

Choosing and purchasing a pharmaceutical laboratory refrigerator requires high precision and consideration of several factors, as this device must be able to store drugs, vaccines, biological samples and sensitive materials in safe, stable and reliable conditions. Choosing the wrong one may lead to drug spoilage, life risks, financial losses and even legal consequences.

1. Stable temperature range (2 to 8 degrees Celsius)

• Check that the device can accurately maintain the internal temperature between 2 and 8 degrees Celsius.

• Temperature stability should be low (maximum ±0.5°C), even with frequent door openings or power outages.

2. High-precision digital controller

• The controller must be Smart and calibratable.

• A digital display capable of showing actual and set temperatures is essential.

• Reputable brands use PID controllers that respond quickly to temperature changes.

3. Audio warning system (alarm)

The refrigerator must be equipped with a smart alarm system for the following:

• Temperature increase or decrease outside the range

• Door left open

• Power outage or compressor failure

• Sensor or control board failure

In advanced models (such as some FG brand models), alerts are also sent via SMS or network.

4. Uniform air circulation (Air Circulation)
