Temperature is a critical environmental factor that can significantly influence the quality, integrity, and longevity of plastinated specimens. As a supplier of plastinated dogs, I have witnessed firsthand the various effects of temperature on these unique anatomical specimens. In this blog post, I will delve into the science behind how temperature impacts plastinated dogs and provide insights for proper storage and handling.
Understanding Plastination and Its Significance
Plastination is a revolutionary technique developed by Dr. Gunther von Hagens in the 1970s. It involves replacing the water and lipids in biological tissues with curable polymers, such as silicone rubber or epoxy resin. This process not only preserves the anatomical structure of the specimen but also makes it odorless, dry, and durable, suitable for long - term display and educational purposes.
Plastinated dogs are valuable resources for veterinary education, anatomical research, and public outreach. They offer a detailed and three - dimensional view of the canine anatomy, allowing students, researchers, and the general public to study the internal organs, muscles, and skeletal system in a hands - on manner.
The Impact of High Temperatures
Chemical Degradation
High temperatures can accelerate the chemical degradation of the polymers used in plastination. Most polymers have a specific temperature range within which they remain stable. When exposed to temperatures above this range, the polymers may start to break down. For example, silicone rubber, a commonly used polymer in plastination, can undergo thermal oxidation at high temperatures. This process can cause the rubber to become brittle, lose its elasticity, and eventually crack.
In the case of plastinated dogs, this chemical degradation can lead to visible changes in the appearance of the specimen. The surface may become discolored, and the texture may become rough. More importantly, the structural integrity of the specimen can be compromised, which can affect its educational value.
Expansion and Warping
Another effect of high temperatures is thermal expansion. All materials expand when heated, and plastinated specimens are no exception. The different tissues and polymers in a plastinated dog may have different coefficients of thermal expansion. This means that when the specimen is exposed to high temperatures, different parts of it will expand at different rates.
As a result, the specimen may warp or distort. For instance, the limbs of the plastinated dog may bend or twist, and the internal organs may shift from their original positions. This distortion can make it difficult to accurately study the anatomical relationships within the specimen, defeating the purpose of plastination.
Mold and Bacterial Growth
Although plastinated specimens are generally resistant to microbial growth, high temperatures can create conditions that are conducive to mold and bacterial growth. When the temperature is high, the humidity in the storage environment may also increase, especially in poorly ventilated areas. Mold spores and bacteria are ubiquitous in the environment, and they can thrive in warm, moist conditions.
Mold growth on a plastinated dog can not only damage the appearance of the specimen but also pose a health risk to those handling it. Bacteria can also cause unpleasant odors and may contribute to the further degradation of the specimen over time.
The Impact of Low Temperatures
Brittleness
Low temperatures can make the polymers in plastinated specimens more brittle. Just as high temperatures can cause polymers to break down, low temperatures can reduce their flexibility. Silicone rubber, for example, becomes stiffer at low temperatures. This increased brittleness makes the specimen more prone to cracking and chipping.
If a plastinated dog is dropped or subjected to even minor impacts when the temperature is low, the specimen may break. This can be a significant loss, especially considering the time and effort involved in the plastination process.
Condensation
When a plastinated dog is moved from a cold environment to a warmer one, condensation can occur on the surface of the specimen. Condensation is the process by which water vapor in the air turns into liquid water when it comes into contact with a cold surface.
The presence of water on the specimen can lead to several problems. It can promote the growth of mold and bacteria, as mentioned earlier. Additionally, water can cause the polymers to swell, which can also affect the structural integrity of the specimen.
Optimal Temperature Conditions for Storage
To ensure the long - term preservation of plastinated dogs, it is crucial to store them under optimal temperature conditions. The ideal temperature range for storing plastinated specimens is between 18°C and 24°C (64°F - 75°F). This temperature range helps to maintain the stability of the polymers and reduces the risk of thermal expansion, contraction, and microbial growth.
In addition to temperature, humidity also plays an important role. The relative humidity should be kept between 40% and 60%. This can be achieved by using a dehumidifier or a humidifier, depending on the environmental conditions.
