Can bacteria be seen with a 1200x microscope

The reason why onions are chosen is because the onion epidermal cells are relatively large and easy to observe, and the onion is purple, and the cells can be seen under the microscope without staining, which is also the reason why many microscopic experiments use onions as samples.

Different microscopes have different magnifications, ordinary light microscopes.

By increasing and improving the performance of the lens, the magnification reaches about 1000-1500 times, but it has never exceeded 2000 times. The outline of the cells can be seen.

Electron microscope.

With a maximum magnification of more than 3 million times, the organelles inside the cell can be seen.

The maximum magnification of an optical microscope is about 2,000 times, so the atoms of certain heavy metals and the neatly arranged atomic lattices in the crystals can be directly observed through an electron microscope.

To look at cells and microorganisms, a 200x microscope is sufficient.

A 1200x light microscope can resolve cell structures. But for the average person, seeing it is almost the same as not seeing it.

A 1200x optical microscope can see many things that cannot be seen with the naked eye, including cells and microorganisms, because generally the size of smaller microorganisms is 1 10um, and the magnification of 1200 times is more than 1mm, which can be seen and relatively clear, some have color themselves, some do not, and generally need to be stained.

1200 times the light microscope 1200 times can see microorganisms, elementary school to high school students are most suitable to adjust the microscope to 1000 times, 1000 times is the clearest one, after 1000 is a little blurry, so the 1200 times light microscope can see microorganisms, adjust the microscope to 400 times can barely see bacteria, under the 400 times microscope, the microorganisms seen are only the size of the tip of a needle, So 1000 times you can see microorganisms, if you adjust the light microscope to 1200 times to see bacteria, although you can see them, but they are half blurred than the original.

A 1200x microscope can see objects below 3 microns, and a general biological microscope has a magnification of about 1000x.

The optical microscope is composed of an eyepiece, an objective lens, a coarse collimator, a fine collimator, a tablet clamp, a clear aperture, a light shield, a converter, a reflector, a stage, a mirror arm, a lens tube, a lens holder, a condenser, and an optical diaphragm.

The electron microscope consists of three parts: a lens tube, a vacuum system, and a power cabinet. The lens barrel mainly includes electron guns, electronic lenses, sample holders, phosphor screens and photographic mechanisms, which are usually assembled into a cylinder from top to bottom; The vacuum system is composed of a mechanical vacuum pump, a diffusion pump and a vacuum valve, etc., and is connected with the mirror barrel through the suction pipeline, and the power cabinet is composed of a high-voltage generator, an excitation current stabilizer and various regulation control units.

You can see the general shape and structure of cells and microorganisms. If you want to see the molecular structure in a cell, you need an electron microscope. Whether it's clear or not, it mainly depends on your conditioning or staining.

The question of what microscope bacteria can be seen with is for reference.

The bacterial individuals are small, and ordinary low-power light microscopes.

You can't see it, you need a high-powered lens to see it.

With a 16x eyepiece, a 100x objective can be seen clearly.

When using a 100x objective, it is necessary to add cedar oil, that is, an oil lens.

As can be seen with an ordinary light microscope, it is already relatively clear under the oil microscope.
