FAQ - Frequently Asked Questions
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.
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.
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.
Product information "Cover glasses, 100 pcs. 24x50mm Boro 3.3"
Extra big cover glasses made from pure white, smooth Borosilicate glass (Boro 3.3). These cover glasses are especially suitable for liquid samples, like plankton or cell culture media. Also useful for skin scrapes from Koi or ornamental fish. You can diagnose a bigger sample volume in one go, making the diagnosis faster and more reliable. The sample will not dry out as fast as usual.
Boro 3.3 is a high tech glass material with excellent surface and optical quality. Keep in mind, that the cover glass is not only a cover, but works as an optical element and will influence the resulting image quality. Most microscope objectives are designed for cover glasses of a certain thickness (Usually 0,17mm; marked on the objective).
The cover glasses are precleaned and ready to use.
Boro 3.3 glass is highly transparent and has excellent surface quality. For UV it is significantly more transparent than soda-lime glass and therefore especially suitable for fluorescence microscopy.
