NEST conducted systematic performance validation on cell culture products, using mainstream “ultra-hydrophilic” products as benchmarks. The comparison was evaluated based on the following key indicators:
01 Core Performance Validation | Key Indicator Analysis
1. Contact Angle — the smaller the value, the better the hydrophilicity

Test Result:
NEST products maintain a stable contact angle of around 15°, significantly lower than competing products, indicating superior surface hydrophilicity that promotes rapid cell adhesion and stable growth.
2. Cell Culture Performance
(1) Cell Morphology

Conclusion: Cells exhibit healthy morphology and a stable culture environment, with more uniform performance compared to competitors.
(2) Cell Viability

Conclusion: NEST products demonstrate better cell viability, consistently slightly higher than competing ultra-hydrophilic products.
(3) Cell Proliferation Rate

Conclusion: NEST shows a clear advantage in proliferation efficiency, helping shorten culture cycles and improve productivity.
(4) Cell Detachment Time
Moderate and consistent detachment time → uniform surface treatment and stable cell condition
Excessive or highly variable time → may indicate over-adhesion
Conclusion: NEST cell culture flasks show slightly shorter detachment times than competitors; both products perform similarly in cell factory applications and meet large-scale culture requirements.
3. Surface Flatness — the structural basis for culture consistency
Flatness refers to the geometric uniformity of the culture surface, typically expressed as maximum height deviation:
Smaller value → smoother surface

Conclusion: NEST offers superior surface flatness, ensuring consistency in large-area cell culture.
NEST cell culture products not only demonstrate excellent surface hydrophilicity, but also deliver more stable overall performance in cell condition, proliferation capacity, structural flatness, and operational consistency—outperforming competing ultra-hydrophilic products.
