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 Science IVM-401 Phase contrast set"
A requirement for phase contrast microscopy are the specially designed apertures to increase the contrast performance. This can achieved by enhancing the bright and dark areas. The background remains bright.

BRESSER Phase Contrast Set for Science Infinity Microscope
€1,109.90*
To enhance contrast according to the refraction index and the thickness of the preparations. The phase contrast set contains four different irises, four different phase contrast objectives (10x, 20x, 40x, 100x oil) and a green color filter. A collimating eyepiece allows easy aligning.
This method is especially suitable for non-stained, low contrast samples (epithelium cells, amoeba, white blood cells) and will also help with visibility of bacteria. Therefore it is used in cell culture and life science where color staining cannot be used.
One position of the filter holder is free. Thus the phase contrast set can also be used as a brightfield condenser with iris diaphragm.
This phase contrast set fits the Science Infinity (item No.: 5760700) microscope.

BRESSER Science MPO 401 Microscope
€2,899.90*
In contrast to usual light, polarized light has a preferred vibration plane of the light waves. Polarized light lets be seen anisotropic objects, whose observable properties are depending on the direction, "in a new light": crystals, but also animal hairs, feathers, muscles, nerve fibres and vegetable cell walls, which have a preferred direction of its biomolecules, show structures now, which were hidden in the normal bright field image. Images made by polarized light are often characterized by a fantastic coloring. Polarization microscopes are used particularly in mineralogy, geology, biology and medicine.
In order to change the object's direction in a controlled way, the Science MPO 401 has a round, center-adjustable and full rotatable object stage with degree scale. The illumination and observation unit encloses e. g. the halogen bulb lamp (20 W) with dimmer, the field diaphragm (used to achieve the Köhler illumination), the 360° rotatable polarizer (for the production of polarized light), centering implements for the objectives and the analyzer attachment (for the analysis of the polarized light). The analyzer attachment is meant for receiving the 360° rotatable analyzer and optional available sliders (Bertrand lens for conoscopy; quartz wedge, lambda plate and lambda/4 plate used in order to get special colour effects). The wide field eyepieces (WF10x), which are also optional available, are placed at the trinocular head with an inclination of 30°. They have eye relief adjustment as well as diopter adjustment. The images shown by them are bright, true colored, sharp and rich in details. Apart from the slips and eyepieces, which were mentioned above, the accessories of the MPO 401 contain a dividing eyepiece (WF10x), the Abbe condenser with iris diaphragm, special polarization objectives (4x, 10x, 40x retractable, 100x-oil retractable), filters (blue, ground glass) and immersion oil.

Nexcope NIB610 professional inverted laboratory microscope
€3,850.00*
OBJECTIVESThe NEXCOPE NIB610 microscope is equipped with a quintuple nosepiece. A planachromatic 4x objective, as well as a 10x, 20x and 40x planachromatic phase contrast objective are already included in the scope of delivery. The objectives are designed for sample vessels with a base thickness of 1.2 mm. This means that standard slides or plates that rest on standard slides can also be used.EYEPIECESThe eyepieces have a large field of view of 22 mm. The high field of view makes them very comfortable even for spectacle wearers. A rubber cup protects against contact. A diopter compensation from -5 to +5 can be set individually for each eyepiece.The interpupillary distance can be adjusted between 48 mm and 75 mm.MECHANICSIn addition to coarse focusing, fine focusing helps to bring the object into focus very precisely. A full turn of the fine focusing knob moves the stage up or down by 0.2 mm. On the right side, the fine focus can be adjusted with a finger. The tension of the coarse focusing knob can be adjusted as desired. The fine focusing knobs are held magnetically and can be set to the left or right, as required. The cross stage offers the possibility of inserting various specimen holders (optional). Thus, slides, 96-well cell culture plates or Petri dishes can be inserted. The microscope can also be operated without a stage. This provides a very large, flat surface, e.g. for larger culture flasks or stacks. If the condenser is removed, a working distance of 187 mm is achieved.CAMERA CONNECTIONThe NEXCOPE NIB610 is specially designed for use with c-mount cameras. C-mount adapters (1x and 0.5x) are available.ACCESSORIES (optional)Hoffman Modulation Phase ContrastRelief 3D ContrastSample holder (Universal holder, Terasaki holder, Petri dish holder (54 mm and 90 mm)PROPERTIESProfessional inverted transmitted light microscopeType of objectives: Planachromatic (60 mm adjustment length)Precise mechanicsVery bright 3W LED illuminationSCOPE OF DELIVERYNIB610 Inverted microscope with quintuple nosepiece4x Objectives (10x, 20x, 40x with phase contrast), 4x as bright field1x Universal phase contrast slider1x Universal holder1x Centering telescope (CT)2x Spare fuses1x C-mount photo adapter1x Hexagonal screwdiver1x Dust cover
