Nettet54 minutter siden · Subsequently, the collagen solution was incubated at 37 °C for 1 h to obtain the artificial opacities visible by eye, which were further stored at 4 °C. To follow the fibrillation process, turbidity experiments were performed by measuring the absorbance of the collagen suspension (λ = 400 nm) at 37 °C (using a NanoDrop 2000c … Nettetmeasured by two different scales. The Vernier reading has least count of 1’ [(1/60)o]. To aid viewing the Vernier scale reading a magnifying glass is provided. The table and the telescope can be fine adjusted by tightening the lock screw and rotating the fine adjustment knobs. The Diffraction Grating is a delicate component.
