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.

BRESSER Erudit Basic Bino 40x-400x Microscope
The BRESSER Erudit Basic Bino is a versatile biological microscope with binocular head. Observing with both eyes makes viewing more comfortable and ergonomic and improves detail recognition. With its high quality optics it is the perfect choice for use in school or hobby. With battery powered LED lighting it can be used anywhere, e.g. for fieldwork or excursions. The microscope can be used on a great variety of subjects, for example thin sections, pond life, or blood smears. It is also a useful tool to look at parasites of pets and livestock (e.g. coccidia, helminths, skin and fur parasites).Three magnifications (40x, 100x, 400x) deliver good resolution to see small details. There is no need to work with immersion oil. The achromatic DIN objectives deliver sharp images with nice detail. The 40x objective is spring loaded to minimize the risk of damage to specimen or objective. The BRESSER Erudit Basic bino comes with a sturdy case for transport and storage, as well as with a smartphone holder for easy and convenient documentation of microscopic images and video.FEATURESType: Biological microscope, transmitted light, binocular headApplication: BiologyBattery powered long life LED light for mobile useCoarse and fine focus, coaxialCoaxial mechanical deskAdjustable Abbe condenser with diaphragm and filter holderComfortable eyepiece tube, 360° rotatableSturdy carry caseSPECIFICATIONSMagnifications: 40x, 100x, 400xAchromatic DIN-ObjectivesEyepiece barrel diameter 23,2mm, field number 18mmBattery powered LED lightSCOPE OF DELIVERYMicroscope body with LED lightWF 10x eyepieceAchromatic DIN-Objectives (4x, 10x, 40x)Abbe-Condenser N.A. 1,25, adjustable, with diaphragm and filter holderSmartphone holderCarry caseBox with preparations, empty slides and cover glasses

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.
