With Levenhuk N20 NG Prepared Slides you can start your observations right away - you don't have to spend much time preparing slides. Just imagine - first, you have to cut a thin slice off the sample; second, you have to place the slice on the slide and cover it - and it's not that simple - you have to be very careful and precise in order to keep the sample unbroken. So to relieve you of the hassle of preparing samples we suggest you buy this special kit that contains everything you need for your observation.

In case you like the process and feel that you are ready to create your own slides, several blank slides with cover glasses are included in the experimental kit. These prepared slides can be used with a microscope of any brand and model.

Looking for something to start your observations with?

Paramecium caudatum is perhaps one of the first protozoans that a young naturalist would explore. These organisms live in fresh standing water. They can also be found in an aquarium, especially if it hasn’t been cleaned for a long time. My ciliate-shoes were taken from the aquarium. Of course, there are only a few ciliate-shoes in aquarium water – the possibility of finding one of them in your microscope’s eyepiece is extremely low. Therefore, we need to increase their concentration. To do so, take a jar (about 17 fluid ounces or 0.5 liters), fill it with aquarium water, put a small spoiled onion and banana peel inside. Put the jar in a warm dark place for 5 to 7 days (don’t close it with a lid).

 

Paramecium caudatum. Animation. Magnification: 64x.

The average size of Paramecium caudatum is 0.02 inches (0.5 mm). For locomotion Paramecium caudatum uses its cilia (about 15 thousand cilia cover its little body!). Moreover, it has two nuclei (a large macronucleus is responsible for nutrition, respiration, metabolism, etc.; and a small micronucleus – for reproduction). Paramecium caudatum feeds on bacteria or algae. The food is caught by an oral groove covered in cilia and then goes to the cell mouth. It is then digested in the digestive vacuole (gullet). Undigested leftovers are ‘thrown out in the open’ through an anal pore (cytoproct). To remove all excess water, our heroine has two contractile vacuoles. They work like pumps on a boat, pumping excess water out of its body. Paramecium caudatum maintains its slipper-like shape thanks to a special membrane (pellicle).
