⚠️ 5 Common Beginner Mistakes
- ① Improper gap calibration
- ② Temperature fluctuation affecting viscosity
- ③ Bubbles in sample causing error
- ④ Exceeding instrument measurement range
- ⑤ Measurement outside linear region
❓ FAQ
+Viscosity vs rheology?
Viscosity is single-point; rheology studies full shear behavior.
+Why cone-plate?
Uniform shear rate, good for low-viscosity samples.
+What does shear-thinning mean?
Viscosity drops under shear; typical of polymers.
