Description

The Levenhuk 870T is a trinocular biological microscope for brightfield observations in transmitted light. It is used in different types of medical centers for urological, dermatological, biological, biochemical, anatomopathological, cytological, and general clinical laboratory research. The microscope can be equipped with a digital camera to output images to an external screen, take photos, and record video. The camera must be purchased separately and is installed in the trinocular tube.

The head can also be tilted 30°. This tilt is comfortable for long-term work. The interpupillary distance is adjustable. The eyepieces have a wide field of view, and so it is convenient for the user to work with large samples. Four plan achromatic objectives are mounted in a revolving nosepiece that is oriented toward the interior. In this position, you can see the objective, and the space above the table is free.

There is no positioning rack on the stage and that improves the ergonomics of the device. The horizontal stage knob is located low for user comfort. The specimen holder is designed for two samples. The focusing knobs allow for coarse and fine focusing adjustment. All of the stage movements are smooth with no jerkiness.

The light source is located under the stage and the Abbe condenser. The LED is brightness-controlled and is powered by 220V. Thanks to LED illumination, the resolution of the microscope is higher than that of analogs with halogen bulbs. Both aperture and field diaphragms make it possible to set up the Köhler illumination.

Can I obtain more than 2000x magnification by using additional optical accessories (Barlow lenses, objectives, eyepieces, etc.)

Customer service:

The microscope’s maximum magnification is 2000x. You can obtain higher magnification with more powerful eyepieces, but it can affect image quality.

nick (2017.10.07)

I want to buy a darkfield condenser for this microscope. I'm upset that this 870T doesn't come with a real darkfield condenser. Can you tell me the size of the condenser mount so I can add myself ?

Customer service:

Dear Nick, thank you for your inquiry. The size of the condenser should be the same as the size of the condenser on your microscope. We've requested the data from our product manager as well. The result will be provided shortly.

nick (2017.10.02)

how do I attach my c-mount camera to this ? (such as nikon 1 or m43 that has c-mount adapter attached)

Customer service:

Dear Nick, thank you for your interest in Levenhuk products. You just need to insert the camera to the tube. The diameter is 23.2 mm. So, if you have another size, you will need to use the adapter that can be purchased in your local camera store. We also have a big choice of microscope cameras. Is there any additional information you might need?

Terry Wells (2017.06.11)

Do I need to tint the bacteria while using a darkfield method? What is more efficient, tinting the bacteria or the darkfield method? If tinting is more efficient, which coloring should I use?

Customer service:

When studying the bacteria, you need to tint them in any case. Food colorings will be perfect.

Max Foster (2017.06.01)

Sorry for the frequent questions. What do I do if the oil spot on the immersion lens has dried?

Customer service:

Try to gently wipe the lens with the soft, dust-free cloth before trying to clean it with alcohol or other aggressive cleaning liquid. You can also use a piece of Styrofoam. First, remove the contaminated lens from the revolver. Rub the frontal lens with by tapping on it lightly with a piece of Styrofoam and turning it around. Dry foam material cleans the frontal lens from dirt (such as immersion oil) really well. You can easily check it by removing the eyepiece from the holder, turning it over and using it as a magnifying glass, keeping it at an acute angle over the front lens. You can simply see through this 10x magnifying glass if the front lens is clean or not. If not, repeat the procedure one more time. Then wipe the lens one more time, check it under the "magnifying glass" and put it back in place.

Willard (2017.05.30)

Can I attach the darkfield to the lenses with 40x and 100x magnification on this microscope?

Thank you, no need to explain anymore, I figured it out myself.

Customer service:

Thank you for your feedback.

Steve Sumrall (2013.06.19)

Please explain how to use immersion objective correctly. I mean for me it seems that I do everything exactly as it's said in manual: I drip immersion oil on the cover glass and lower objective lens so it touches the oil… but I can't see anything, only white spot. Maybe I need to apply some oil on the condenser as well?

Customer service:

The oil immersion objective (usually 100x or more) is designed for use with a drop of special oil, placed between it and the specimen. First you should focus on the area of specimen that you are going to observe using oil immersion objective. Then carefully place a drop of immersion oil on the cover slip over that area, and lower the oil immersion lens into place.

George Bates (2013.05.27)

Hello. Where can I buy oil of these two types - A and B? And which of them magnifies more or what's the difference between them? Thank you. Can a vegetable oil be used? I want to purchase Levenhuk_c800 camera and Levenhuk 870T Biological Trinocular Microscope. I need your guidance.

Customer service:

Unfortunately we don’t have immersion oil in our product range.
Type A is a classic immersion oil
Used as immersion liquid while working with apochromatic and achromatic objective lenses of microscopes of all types, except fluorescence microscopes, in visible spectrum.
Type B is a professional immersion oil
Used as immersion liquid while working with apochromatic and achromatic objective lenses of microscopes of all types, except fluorescence microscopes, in visible spectrum. Intended for microscopes with artificial illumination and image viewing system first of all. Compared to the classic immersion oil, immersion oil of B type has lower velocity and higher light transmittance.
No, vegetable oil cannot be used.
Do you want to process with the order?
