SUMMARY

To observe microorganisms like E. coli, a microscope with a 100X objective (resulting in over 1000X total magnification) is necessary for detailed visualization. A 40X objective (over 400X magnification) can suffice for stained samples. For affordable options, eBay is recommended for purchasing microscopes, although laboratory settings typically utilize higher magnification instruments. Observing Brownian movement requires specific conditions and may not be visible with lower-quality equipment.

PREREQUISITES
  • Understanding of microscope objectives and magnification levels
  • Familiarity with microorganisms such as E. coli, tetanus, and botulism
  • Knowledge of staining techniques for microscopy
  • Basic principles of Brownian motion
NEXT STEPS
  • Research the specifications and capabilities of microscopes with 100X and 40X objectives
  • Learn about staining techniques for better visualization of microorganisms
  • Explore eBay and other marketplaces for affordable microscope options
  • Study the conditions necessary to observe Brownian movement effectively
USEFUL FOR

This discussion is beneficial for biology students, amateur microscopists, and anyone interested in observing microorganisms and their behaviors under a microscope.

can anybody tell me how much maginfication it takes to see certain micro organisms such as e coli, tetanus, botulism etc. ? where can I find a suitable microscope that doesn't cost an arm and a leg?

To see have a good view of E. coli, you need a 100X objective (more than 1000X magnification) to see good details although a 40X objective (more than 400X magnification) is sufficient to see the bacteria when they are stainned. I would not stained if I was at home because it is a messy operation

Have you try ebay to find an inexpensive microscope

This one would be sufficient but in lab we use something with more magnification power.

Brownian movement

Help. I got a 100 x toy and I can't see the Brownian movement ever. No one has ever been able to tell me what magnification I need. Generally I try aqueous solution.
