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 Bresser cover slips have a size of 22 x22 mm and a thickness range from 0,13 – 0,17 mm. They are used to cover the sample on the slide. A thin and even sample is necessary for observations with high magnification. These cover slips are designed to work with all objectives that have the thickness of 0,17 mm included in their optical design. Usually you find this number printed on the objective. For beginner’s and student microscopes, these cover glasses are also suitable. FEATURES Cover slips, square, size 22x22mm Soda lime glass pre cleaned SCOPE OF DELIVERY 100 cover slips Kunststoff-Box

This crosshair micrometer eyepiece enables the measurement of a specimen. The crossed scale facilitates horizontal and vertical measurement without rotating the eyepiece. For optimal visibility, the crosshair is focusable. The barrel diameter is 30 mm, allowing for a large field of view of 22 mm. An additional micrometer slide is required for calibration. Two different measuring slides are available: A measuring scale (Item No. 5916710): 1 mm, divided into 0.01 mm increments. Two measuring scales (Item No. 5916720): 10 mm, divided into 0.1 mm increments, and 1 mm, divided into 0.01 mm increments. This BRESSER micrometer eyepiece is compatible with the following BRESSER microscopes: Science TFM-201 (5750800) Science TFM-301 (5750900) Science Infinity (5706700) Science ADL-601F (5770500) Science ETD 201 (5806200) Science ETD 101 (5806100) SCOPE OF DELIVERY 1x BRESSER WF10x 30 mm crosshair micrometer eyepiece
