Which microscope to choose so that it does not gather dust on a shelf
The microscope entertains and develops. He will introduce you to the microcosm - the beauty of the structure of objects and bizarre animals hidden from our eyes. It will help to see how things are arranged. And through this and understand their properties - why they behave the way they behave. The microworld is fascinating.

A microscope is a wonderful gift. Both the child and the friend will be delighted. Yes, and buy yourself - shameless. It only happens that he carries away only the first couple of days. And then it stands on a shelf - it’s a pity, only it takes up space. Therefore, we will tell you which microscope to choose. We show serious models and those with which it is not a pity to just play around. But only those that do not limit the curious, if interest in the microworld has not died away.
What you can see, and how it depends on the increase
In the photographs multicellular seaweed - spirogyra. At an increase of 40 times, you can see individual algae cells, at 100 - it is already clearly visible. At 400, the contents of the cell are discernible. Increasing further is no longer interesting.
Human blood cells - red blood cells, white blood cells and platelets - are easily distinguished with an increase of 800 times. Here it is interesting to increase up to 2000 times. The reason is bacteria that are so small compared to blood cells.
Slow-moving animal - a barely distinguishable point for the naked eye. Her life can be observed at a minimum magnification of 40 times.

Slow-moving animal - a barely distinguishable point for the naked eye. Her life can be observed at a minimum magnification of 40 times.
Magnification. The multiplicity of increase usually starts at twenty and ends at two thousand. It’s rare when an increase of over a thousand comes in handy, just to see bacteria. Most of the time they use minimal magnification - to find the object of observation. And bring it closer when they want to consider it.
Focus. The minimum magnification is used for navigation because all objects are clear. And when enlarged, most of the space is blurred. And then the focus is finely tuned to the object of observation. It’s great if microscopes with a high magnification have two focus control knobs - for coarse and fine tuning. With one pen you are tormented to focus on the subject.
Lighting. The stronger the lens increases, the less light enters it. Therefore, without a powerful light source - it is dark, objects are not visible. Inadequate lighting is so annoying that it quickly becomes uncomfortable.
What is a microscope that does not limit creativity
We recommend two models that everyone can do - the optical Levenhuk 320 and the digital Levenhuk D70L . These microscopes will help you see stunning pictures of the microworld, simply unattainable with entry-level models. Here is a checklist with the characteristics of such a microscope, which does not limit:

Here is a checklist with the characteristics of such a microscope, which does not limit:
- Condenser Abbe - gives powerful light. After all, the higher the magnification, the darker the picture becomes.
- Immersion lens - gives an increase above 1000 times.
- Achromatic lenses - so that the image does not distort due to high magnification.
- Moving subject table - move the drug to quickly find the object of observation.

Leather Seat Cleaning Mix
Synthetic leather coverings more easily stain than original leather. While the former is actually a kind of plastic, the latter takes longer to stain, grime or crack.
Despite the differences, the secret to how to clean leather seats is the same for both of them: just invest in a homemade 500 ml water mix with a spoonful of neutral detergent.
Put the mixture in a spray bottle and splash on the coating, rubbing gently with a soft cloth. Then wipe it dry, as excess water is harmful to the material.
If the stain or dirt is large or difficult to remove, use caution in the form of scrubbing. Make gentle, circular motions so as not to damage the coating.
Although cleaning the leather seat seems simple, attention is needed, as there are many materials and products that cause stains on the seat and damage the material, especially light colored ones. The dye of jeans, children's crayons or even body sweat can stain the leather.
