Do we need Phase Contrast?

Hi Microbe Hunters,

1) What is the specimen needed to dye in order to see it in Bright Field?

2) Can we use Phase Contrast to see all of these specimen instead, without dyeing them?

Re: Amscope T720QB and Phase Contrast

Hi, After reading the manual, I just realize that the big knob on the right side of T720 is NOT focusing knob, but the light dimming knob! I am right hand.
