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 "BRESSER additional Objective 2x (ETD-201)"
In some applications, it is desirable to increase the magnification by an additional 50x. With this 2x lens, you can use the Science ETD-201 at magnifications of 16 to 100x.. The working distance is reduced slightly. However, the depth of field is higher at the resulting magnification than when the magnification is increased by simply using another pair of eyepieces. A conversion lens is therefore the accessory of choice for magnifications greater than 50x.
This additional lens is compatible with the following BRESSER microscopes:
In some applications, it is desirable to decrease the magnification factor. With this 0.7x lens, you can use the Science ETD-201 at magnifications of 5.6 to 35x.. The working distance is increased slightly. This is particularly useful if you need to work under the microscope. A larger and brighter field of view is also useful when using a microscope camera. The working distance is 137 mm.
This additional lens is compatible with the following BRESSER microscopes:

High-quality complete set for precise analyses and sharp image transmission:
This powerful set combines the Science ETD-201 stereo microscope with the advanced MikroCam SF UHD camera. It is ideally suited for detailed observations and documenting work results.The Microscope in DetailThe BRESSER Science ETD-201 is an optically high-quality reflected and transmitted light stereo microscope.
It is suitable for use in medicine, agriculture and forestry, forensics, scientific research institutes and schools as well as for assembly and inspection of small components in precision mechanics and electronics.
The particularly wide base with object table and the exceptionally large height adjustment range allow the observation of larger objects. The instrument features LED reflected and transmitted illumination, which can be used individually or combined and each continuously adjustable. The reflected light incidence angle is particularly user-friendly adjustable and lockable. With interchangeable widefield eyepieces (WF10x) and a 6.25x stereo zoom objective (0.8x-5x), a continuous magnification range of 8x to 50x is realised. The click-stop zoom locks at predefined positions, so that magnifications can be exactly reproduced, e.g. for measurements at the microscope. The eyepieces have a field number of 22, allowing a visible field of view between 4.5 and 27.5 mm.
The eye distance and dioptre adjustment are individually adjustable. The trinocular microscope head can be rotated 360° and has two eyepiece tubes inclined at 45° as well as a separate, parfocally adjustable camera tube for connecting a C-Mount camera, or MikroCam, up to a 1/2" sensor size.

This allows observations of objects to be easily documented and shared with others. The high frame rate of the MikroCam SF series enables the creation of videos with smooth image flow. The built-in Sony sensors offer good image quality, colour reproduction and dynamics.
The included software supports, among others, the following languages: German, English, French, Spanish, Italian, Polish, Turkish.
The MikroCamLabII software offers a wide range of functions. Essential functions (e.g. exposure time and sensitivity) can be controlled automatically or manually.Very convenient are the functions for so-called focus stacking (for high depth of field) and the creation of a mosaic or panorama. These two functions can be performed with a previously recorded image series or directly from the live view. Creating depth-sharp images using live focus stacking (EDF) is possible within minutes with the MikroCamLabII software. While you focus on the microscope, the software gradually builds the finished, completely sharp result image without further input. This way you get impressive, sharp image results in a very short time.The measurement function* included in the software helps you determine sizes or display a scale. You can measure distances, angles or areas with just a few clicks. Extensive functions support you, e.g. measuring circles with area and radius or complex polygons.
Measurements can be performed on the recorded image as well as in the live image. The MikroCamLabII software also has extensive algorithms for automated image evaluation, e.g. for particle counting or area evaluation.
The housing has a C-Mount connection thread and can therefore be used on microscopes from various manufacturers. We are happy to advise you which MikroCam is optimally suitable for your microscope.
For use on devices with a 23.2 mm mount, an optional 0.5x reduction optic (Art. No. 5914015 (fixed), Art. No. 5914005 (variable)) is available. For special applications, e.g. with a C-Mount objective, the camera can also be mounted on the integrated 1/4" tripod thread.
*For calibration of the measurement function, a suitable measuring tool is required, e.g.: Art. No. 5916710 or 5916720.

The new BRESSER Weather Station 5-in-1 combines in a unique way a compact design with an extensive information service. The very compact and multifunctional outdoor sensor requires only little space and thus can be placed almost anywhere. A pipe clamp and screws for the attachment at poles (pipe diameter of about 25-33 mm) as well as a stand are already included!The 5-in-1 outdoor sensor transfers reliably all measured values for wind speed, wind direction, humidity, temperature and precipitation rate to the base station. On the clearly structured display of the base station not only these values can be read but also a multitude of history data. The latter allows the internal storage and evaluation of measured data over a period of 24 hours. From the collected measured data, the weather station calculates a very reliable local weather trend forecast for the next 12 hours, depicted by six graphic symbols on the display. For minimum and maximum values an individual alarm can be programmed, which gives an acoustic and a light signal when the defined value is reached. For outside temperatures of -3 °C and below a special alarm for frost/ice warning can additionally be activated.A poor indoor climate often involves health risks especially for children and the elderly. The BRESSER Weather Station 5-in-1 offers you a smart feature to deal with this. The indoor climate indicator informs steadily about the indoor climate with a symbol.Furthermore the BRESSER Weather Station 5-in-1 features a radio controlled time and date setting (DCF time signal). Already a few minutes after switching the device on the current Central European Time (CET) and the date with weekday are displayed automatically. For the “moonstruckers” also the different phases of the moon are shown. An alarm function with snooze mode is also integrated.FEATURESColour-display5-in-1 outdoor multi sensorInside temperature (°C/°F) and humidityOutside temperature (°C/°F) and humidityWind direction and speedGraphical weather trend display (12 hours)Beaufort index (scale for the classification for wind speeds)Precipitation rate with history (day/week/month)Air pressure with history (24 hours)Heat indexDew pointRadio controlled time and date settingPhases of the moonAlarm functionIce/frost warningHi/Lo-AlertMin/Max memory (up tp 24 hours)LED background light, amberGood to know: The sensor pairs with multiple base stations at once – perfect if you want to keep an eye on conditions in different rooms.SCOPE OF DELIVERYBase station5-in-1 Multisensor with mounting materialPower plugManual
