With the Levenhuk K50 Experiment Kit, you will learn how the world is arranged. You can look at it from the inside and see what is not seen to the human eye: exactly what we eat, drink, and wear. The Levenhuk K50 will open a whole new dimension for you—the world at the cellular level.
Hatchery for Artemia (a sea organism used as a food source for fish)
Observing the microworld, we see the whole new universe of complex microorganisms, cells, tissues, we can examine the inner structure of things that surround us in our everyday lives and learn how they function. Levenhuk K50 Experiment Kit is a wonderful choice for children and curious adults.
5 ready-to-use slides and 5 blank glass slides
Levenhuk K50 Experiment Kit contains everything needed to organize your own home laboratory. You can observe ready-to-use samples, make them yourself, grow brine shrimp, and conduct various experiments. The detailed guide included in the kit will help you with that.
Four flasks with yeast, brine shrimp, pitch, and sea salt
Microtome – a tool that allows you to make very thin (fraction of a millimeter) slices of samples, which is necessary for studying the sample under a microscope
Dropper for working with liquids; Metal tweezers for working with small objects
The detailed guide will teach you how to properly prepare for and conduct various experiments. You will be able to observe the reaction of cells to cold, heat, or exposure to various chemicals, for example.

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).
