2025-10-28
High-precision environmental control equipment developed by Jice (Nanjing) Technology Co., Ltd. stands as a critical support in addressing challenges posed by fluctuating precision environments, thanks to its exceptional capabilities such as temperature control with an accuracy of ±2 mK (±0.002℃), humidity control within ±0.3% RH, and compliance with the ISO Class 1 cleanliness standard.
In the field of precision experiments, environmental stability is the core prerequisite for ensuring accurate and reliable experimental results. However, environmental fluctuations such as temperature variations, humidity changes, airflow disturbances, and impurity contamination can lead to increased measurement errors and irreproducible outcomes. To address these critical challenges, JiCe (Nanjing) Technology Co., Ltd. The highly precise environmental control equipment developed by our R&D team, with capabilities such as maintaining temperature stability at ±2 mK (±0.002°C), controlling humidity within ±0.3% RH, and ensuring an ISO Class 1 cleanroom standard, has become a critical support for addressing challenges related to precise environmental fluctuations.
Affecting the Stability of the Experimental Environment
Temperature fluctuations
Air disturbances easily lead to uneven temperature distribution in the experimental area, resulting in localized overheating or overcooling. For highly precise optical experiments, delicate chemical reaction studies, and other scenarios with extremely stringent temperature requirements, even a tiny temperature fluctuation of ±0.1℃ can trigger shifts in material thermal expansion coefficients or cause abnormal reaction rates, directly compromising the accuracy and reproducibility of experimental results—and ultimately becoming a significant source of experimental error.
Jice (Nanjing) Technology Co., Ltd.'s high-precision environmental control equipment features a self-developed, advanced temperature-control algorithm and multi-level temperature-control patented technology. Under static operating conditions, it achieves temperature stability as low as ±2 mK (±0.002°C), with temperature uniformity better than 16 mK/m. This ensures a stable thermal environment ideal for demanding experiments such as optical interferometry and material synthesis, effectively eliminating temperature fluctuations that could disrupt experimental results.
Humidity changes
Traditional air conditioning systems accelerate moisture evaporation, leading to unstable humidity levels in the experimental environment. In cell-culture experiments, fluctuations in humidity can disrupt cellular metabolic activity and compromise cell growth conditions. Moreover, these fluctuations may also cause condensation on the circuits of sensitive instruments or rusting of mechanical components, ultimately shortening the lifespan of the equipment.
Facing the challenge of humidity fluctuations, Extreme Measurement's high-precision environmental control equipment employs a collaborative solution of "absolute moisture content control in the overall environment combined with localized micro-adjustments for the micro-environment," enabling precise humidity stability maintained within ±0.3% RH. This exceptional level of humidity control effectively preserves the active state of biological samples, ensures consistent results in material aging tests, and simultaneously provides an ideal humidity environment for sensitive instruments, ultimately extending their operational lifespan.
Interfering with the experimental subjects
In microscale experiments such as cell culture and nanomaterial research, tiny vortices generated by air disturbances can physically interfere with experimental samples. Cell suspensions may become unevenly distributed due to airflow, leading to inaccuracies in cell counting; meanwhile, nanoparticles could be subjected to shear forces from the air flow, altering their aggregation states and directly affecting the reliability of experimental observations and measurement results.
JiCe achieves localized temperature control while preventing airflow turbulence through its targeted air curtain design and precise flow-rate control. Combined with an ISO Class 1 cleanroom environment (with particles ≥0.1 μm no more than 10 per cubic meter), this setup ensures that microscopic samples remain undisturbed, providing a reliable foundation for cutting-edge microscale experiments.
Affecting the Accuracy of Experimental Instruments
Take optical instruments as an example: air disturbances that cause localized variations in temperature and humidity lead to uneven refractive indices within the light path, resulting in deviations in the propagation direction of light. In high-precision optical experiments such as laser interferometry and spectral analysis, these path deviations directly translate into measurement errors, compromising the instrument's resolution and accuracy. For instance, in OCD (Optical Coherence Tomography) devices, even a temperature fluctuation of just 0.05°C can reduce imaging resolution by up to 30%.
Jice High-Precision Environmental Control Equipment establishes a triple safeguard system of "constant temperature + cleanliness + anti-interference" for optical instruments. With a temperature control accuracy of ±0.002℃, it eliminates temperature gradients that could affect the refractive index of air; its ISO Class 1 cleanliness level ensures particles do not scatter or disrupt the optical path; and it helps reduce optical measurement errors to within the precision limits of the instruments themselves. Currently, this equipment is widely used to maintain optimal operating conditions for advanced optical devices such as lithography machines and vertical interferometers.
Introducing impurities and pollutants
Air turbulence from the air conditioning system can stir up dust particles in the surrounding environment. If these particles settle onto experimental samples or critical components of instruments, they can lead to serious issues: In semiconductor manufacturing processes, even tiny dust particles may cause unreliable bonding, short circuits, and ultimately product defects; meanwhile, in high-precision surface inspection experiments, dust particles can trigger false-positive scratch detections, compromising the accuracy of test results.
JiCe (Nanjing) Technology Co., Ltd.'s high-precision environmental control equipment features a multi-layer, highly efficient filtration system. By combining advanced physical filtration with dynamic airflow management, it achieves a cleanroom environment as stringent as ISO Class 1, effectively capturing even particles as small as 0.1 μm. In applications such as semiconductor manufacturing, optical component processing, and biocell culture, this equipment minimizes particle-related experimental defect rates, providing a pristine environment that supports cutting-edge manufacturing and precision experimentation.
JiCe (Nanjing) Technology Co., Ltd.'s high-precision environmental control equipment delivers unparalleled stability, offering temperature control accuracy as fine as ±2 mK, humidity stability down to ±0.3% RH, and an ISO Class 1 cleanroom environment with exceptionally low air-flow fluctuations—creating a seamless, disturbance-free, and pristine setting for sensitive experiments. Whether it’s used in semiconductor manufacturing, life sciences research, optical measurements, or materials analysis, this equipment serves as the "environmental cornerstone" for precision experiments, dramatically enhancing both experimental accuracy and reliability while driving high-quality advancements in scientific research and cutting-edge manufacturing sectors.
