Surface hydrophilicity (contact angle)
Cell culture performance (morphology, viability, proliferation capacity)
Surface flatness
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.
