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.

Warning notes
  • Store, transport, and use the camera only within the permissible humidity (<95%) and temperature range (-30°C to +55°C). Avoid dusty and highly electromagnetic environments.
  • Prevent impacts, drops, crushing, and shaking of the device.
  • Do not immerse the device in liquids.
  • Handle and transport the device carefully. Do not transport the device without packaging. Use the provided packaging or equivalent materials, as the camera could otherwise be easily damaged.
  • Store the device only in well-ventilated areas and avoid strong electromagnetic fields.
  • For extended storage, make sure the battery is fully charged every 6 months, as failure to do so may cause damage.
  • Never aim the lens directly at intense energy sources such as lasers or the sun.
  • Improper handling or changing of the battery can lead to explosion/fire.
  • Do not use the charger for other battery types than the ones provided. Keep a 2-meter distance from flammable materials when charging the batteries.
  • Ensure that the power cables are always correctly inserted into the sockets.
  • Always use the power supply with only one device, as it may overheat.
  • Immediately remove the power supply if smoke, burning smells, or noises occur during charging. Contact the service center.
  • Do not open the device on your own.
  • Remove the power supply before cleaning the device.
