BRESSER Erudit Basic Bino 40x-400x Microscope

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.

The set slides / cover plates is use to make Preparations for biological microscopes. The slide holds the preparation it will be covered with a cover plate.SCOPE OF DELIVERY50 blank slides 76x26mm100 cover plates (0,17mm thickness)These BRESSER slides and cover glasses are compatible with the following BRESSER microscopes:Duolux (5012000)BioDiscover (5013000)BIORIT (5101000)Erudit DLX (5102000)ERUDIT MO (5110000)Researcher Bino (5722100)Researcher Trinocular (5723100)LCD microscope (5201000, 5201002)Science TRM 301 (5760100)BioScience Bino (5750500)BioScience Trino (5750600)Science ADL 601 P (5770200)Science ADL 601 F (5770500)Science MPO 401 (5780000)Science IVM-401 (5790000)

The Analyth STR comes with 3 different magnifications, that can easily be switched by turning the objective. It is easy to change magnifications from 10x to 20x or 40x. The stereo microscope will show structured objects nicely in 3D, which is especially impressive. The low starting magnification of 10x is helpful when working with children and will show objects in full up to a size of 20mm. With the wide magnification range, the Analyth STR is a versatile instrument. You can use it to view insects, plants, minerals and much more. It is useful for hobbyists, in schools and more. Typical professional applications include quality control, gardening or farming (pest control), hydrobiology and much more.The interpupilllary distance and the diopters can be adjusted to your needs. The eyepieces feature a big field of view of 20mm. They are equipped with rubber eyecups and have a locking screw to prevent loss or damage during transport.The power supply can be achieved through the AC adapter or with a set of 3 AA type batteries (batteries not included). This makes the microscope  perfect for mobile use, e.g. outside in the garden or for biology field work.
