In the scenario of precision operation in the laboratory, the choice of material directly affects the reliability of experimental results and the efficiency of operation. As a high-end product in the silicone rubber sheet family, gas phase silicone rubber sheet has gradually become the material of choice for chemical analysis, biological experiments and precision instrument operation due to its unique process and performance. In this article, we will analyze the three key benefits of gas-phase silicone rubber sheet in the laboratory environment to help you understand its irreplaceable value.
Advantage 1: Ultra-high purity and chemical inertness to ensure the accuracy of experiments
Vapor/Gas phase silicone rubber sheet adopts vapor phase silica as the core raw material and is made through high temperature gasification and condensation process. Compared with the traditional silicone rubber sheet, its silica gel molecular structure is more uniform and dense, with extremely low impurity content (usually ≤ 0.1%), and almost no release of volatile organic compounds. Laboratories often come into contact with a wide variety of chemical reagents, including strong acids, strong bases and substances with strong oxidizing properties. Gas phase silicone rubber sheets have excellent chemical stability, even in the case of long-term contact with these complex chemical reagents, but also to maintain their own performance is not damaged. Regular silicone rubber sheet contains a small amount of catalyst residue, long-term exposure to corrosive reagents prone to chalking, while the chemical inertness of the gas phase silicone rubber sheet can extend the service life of more than 3 times. These features make it excellent in the following scenarios:
Chromatography: When used as a carrier for thin layer chromatography (TLC), it prevents impurities from interfering with the color development reaction and ensures the accuracy of detection results.
Precision Weighing: No static adsorption or particle shedding when used on the operating surface of the electronic balance, protecting the precision instruments.
Corrosive Environment: It shows excellent resistance to strong acids (such as concentrated sulphuric acid), strong bases (such as sodium hydroxide solution) and organic solvents (acetone, ethanol), thus avoiding experimental contamination due to material corrosion.
Advantage 2: Excellent temperature resistance, adapt to the extreme experimental environment
With a wide range of temperature resistance from -60℃ to 300℃, the gas phase silicone rubber sheet can not only withstand the repeated operation of autoclaving (121℃) and dry heat sterilization (180℃), but also stably carry the instantaneous high temperature impact of hot bench experiments, and at the same time, maintain the flexibility and anti-cracking characteristics in the ultra-low-temperature refrigerator (-80℃) to effectively avoid the risk of deformation, decomposition or embrittlement of the material, which provides durable and stable physical support to experimental processes in extreme temperature environments. Provide durable and stable physical support for the experimental process under extreme temperature environment, which significantly improves the experimental efficiency and reproducibility of the results.
Autoclave Compatibility: It can be directly autoclaved (121°C/30min) or dry heat sterilized (180°C/2h) without frequent replacement of consumables.
Thermal Stability Support: No thermal decomposition when used as a sample support layer in thermogravimetric analysis (TGA) and other experiments,
Suitability for Low-temperature Experiments: It remains flexible in ultra-low-temperature refrigerators (-80℃), avoiding the risk of brittle cracks.
Advantage 3: Anti-aging and long life, reduce the comprehensive use of costs
Laboratory high-frequency, high-intensity use of scenarios, the durability of the gas phase silicone rubber sheet advantage is particularly prominent, a biological laboratory, for example, the average annual replacement of regular silicone rubber sheet3 times, while the service life of the gas phase silicone sheet can be up to 2 years or more, a comprehensive cost reduction of 40%.
Resistant to UV and Ozone Aging: No cracking or yellowing of the surface under UV sterilizing lamp irradiation or ozone sterilization environment.
Wear-resistant and Anti-scratch: The surface hardness reaches Shore A 60±5, which can withstand repeated friction of glassware and avoid contamination by debris.
Easy to Clean and Maintain: The dense, non-porous structure prevents liquid penetration and can be rapidly sterilized with 75% alcohol or sodium hypochlorite solution.
Conclusion
Gas phase silicone rubber sheets have become the basic equipment in modern laboratories due to their purity, extreme temperature resistance and long durability.
