Levenhuk D70L Digital Microscope can be used for studying both transparent and opaque objects in transmitted light using the bright field method. This microscope is ideal for biological researches or teaching demonstrations - it's very convenient to study samples in a group of students, they can see it on the 3.6" LCD display in a real time.
All optical elements of this microscope are made of high-quality multi-coated glass that's why with Levenhuk D70L Digital Microscope you will be surprised by sharpness and brightness of produced images. Microscope produces optical increase of 40, 100 and 400x while digital zoom allows yielding magnification up to 1600x.
This model integrates two light sources which provide sufficient illumination even while working in a dark room. Using Led illumination allows you to reduce energy consumption. You can use both lights at the same time or only one of them, so you can choose the best lighting conditions for each sample.
Moreover, Levenhuk D70L Digital Microscope has revolving nosepiece, focusing arm, 3 objectives and stage with specimen holder and metal construction.
The instrument is powered by AC power. The microscope also runs on batteries so you can use it outdoors.
The microscope includes:
Levenhuk D70L modules:
Focusing arm
The focusing arm located on the stand allows vertical movement of the stage. Handles are lined up at the both sides of the stand. The total focusing value is at least 10 mm (0.4 in).
Stage
The stage is fixed on the bracket secured on the focusing arm block. The specimen holder is located on the stage surface, and the diaphragm disk is attached to the lower part of the stage. A stopping screw limits movement of the stage bracket, which eliminates possible contact between the objective and the specimen.
Revolving nosepiece
The revolving nosepiece holds the objectives; to replace an objective, rotate the ring until it reaches the fixed position.
Head
3.6" LCD display.

Maintenance of the microscope
In case dust soils the objective lens deep in the casing, carefully wipe the lens with a clean cotton swab slightly moistened with Levenhuk cleaning spray or spirits mixture. If you notice dust inside the objective or a film on the inside of the lenses, the objective should be sent for repair.
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).
