FAQ - Frequently Asked Questions

I want to examine microorganisms such as lactic acid or photosynthetic bacteria – which microscope is suitable?

For this application we recommend the BRESSER Erudit DLX 40-1000x microscope in combination with a USB camera, e.g. the BRESSER MikroCam 1.3 MP. This solution offers better image quality and flexibility than a simple LCD microscope.

If you want to identify bacteria, it is usually more useful to create a culture. Microscopes are generally only sufficient to determine whether the bacteria are, for example, spherical or rod-shaped.

Where can I find the Barlow lens?

The Barlow lens is already installed in the eyepiece tube on many devices. It can be pulled out at the upper ridge to use the zoom function.

At higher magnifications the image is blurry or lacks contrast – what can I do?

Possible causes:

Sample too thick / unsuitable: Use thin samples or fixed smears.
No cover glass or incorrect thickness: Objectives are optimized for cover glasses.
Condenser incorrectly adjusted: Do not open the diaphragm too far – otherwise contrast will be low.
Magnification too high: Rule of thumb: maximum 1000 × objective aperture. Example: With a 40x objective with aperture 0.65, the limit is about 650x.

BRESSER Set Microscope Slides

Slides and cover glasses are an indispensable accessory which has also impact on the image quality. For most biological microscopes, the cover glass thickness is an important optical parameter, which is therefore included in the optical design and, if so, printed on the sleeve of every objective. You can usually see the number 0.17 which is the thickness in millimeters. For demanding applications in the laboratory, or for microphotography, using cover glasses with the desired thickness and high quality is necessary.The cover glasses included in the set are made of Boro 3.3 glass and are standardized to a thickness of 0.16-0.19mm. So they match the desired 0.17mm really good and give the best possible image quality. These Boro 3.3 cover glasses are pure white, without streaks and are pre-cleaned and ready to use. They are also especially suitable for fluorescence microscopy.The slides are made of soda lime glass, and have ground edges for safe handling. They have a matte field for writing on both sides (top and bottom). Slides and cover glasses are packed separately and in a vacuum sealed bag, containing moisture absorbent. They can be stored for a long time without loss of quality from hydrolysis and are easy to take out.
