At the BRESSER Science IVM 401, the usual direction of illumination and observation is inverted: One illuminates the sample from above and observes it from below. This type allows for the microscopy of sediments and transparent living organisms, which are found at the bottom of a liquid medium. For example, plankton or protozoa at the ground of culture bottles, which should not turned over, can be investigated. So, this special microscope is suitable for public water departments, research institutes and universities, for medical treatment, animal husbandry, agriculture, limnology etc. The Science IVM 401 has a large fixed object plate with stage moving system, a powerful halogen bulb illumination (30 W) with dimmer and field diaphragm, and a fourfold nosepiece. The trinocular head is turnable and bears 30° inclined eyepiece tubes and a photo tube. There are eye relief adjustment and diopter adjustment, as well as coaxial coarse and fine focusing knobs. As accessories, which are available on request, you have a big choice: Wide field eyepieces (WF10x, WF16x), planachromatic DIN objectives (10x, 25x, 40x), planachromatic DIN phase contrast objectives with annular diaphragm (10x, 25x, 40x), condenser (working distance 30 mm; with phase contrast), condenser (working distance 70 mm), different filters (blue, green, ground glass) and specimen holders for rectangular or round culture utensils.

The BRESSER dark field condenser dry (Infitiy/TFM) directs the light to the side of the specimen. It increases the contrast of the specimen considerably, especially with highly transparent specimens. This type of illumination makes the observed object appear bright, against an almost black background. In this way, structures can be detected that are hardly visible in the bright field. The dark field condenser dry (Infitiy/TFM) is suitable for lenses that do not require oil immersion. FEATURES Contrast increase intensification of colors Details that are hardly visible in the brightfield can be recognized much better Suitable for lenses without oil immersion The condenser is compatible with the following BRESSER microscopes:5750900 Science TFM-3015760700 Science Infinity SCOPE OF DELIVERY 1x Dark Field Condenser

The BRESSER TRM-301 is a trinocular biological microscope of first-class quality: This means excellent imaging, good ergonomy, high stability and a modern attractive design. It is a laboratory microscope, which permits an intensive use, e.g. in medicine, biology, agriculture and industry area. Also, we can recommend it to the engaged hobbyist as his "microscope for a lifetime". A particular important feature of the TRM-301 is its ability for the Köhler illumination. This optimal illumination is bright, cool (going easy on the object), homogenous, reflex free and rich in contrast, so it makes the full use of the microscope optics. The Köhler illumination is standard for scientific research and microphotography. It is achieved with the fixed field diaphragm and the adjustable Abbe condenser (numerical aperture 1.25; with iris diaphragm). Naturally, the TRM-301 has the other features, which are typical for high-quality microscopes: lengthwise and cross moveable stage, ergonomic coaxial focusing knobs (fine focus: 200 µm / full turn), continous dimmer, planachromatic objectives (4x, 10x, 40x, 100x-oil retractable), 10x wide field eyepieces (mounted in 30° inclined eyepiece tubes), adjustment of eye relief, diopter adjustment and the phototube.

The NIB 630 is the flagship of the NIB600 series of inverted microscopes. With such an inverted design, the device enables the microscopy of plankton, microalgae and cell cultures. Cell cultures can be examined directly in the culture vessel without taking samples. For particularly easy sample handling, it is equipped with a tiltable lighting unit. This means that even tall vessels can be placed comfortably without bumping against the lighting unit. The microscope head is equipped with a height-adjustable ergo viewing head. This allows users of different heights to adjust the microscope to a comfortable and ergonomic viewing height with a single hand movement. This special microscope is used in water management offices, research institutes and universities, in human and veterinary medicine, agriculture, marine biology, limnology, aquaculture and many more. The integrated display informs you at any time about the selected magnification and the status of the illumination as well as the ECO mode. The brightness can be programmed for each objective so that there is no need to readjust when changing magnification and the user is not blinded. OBJECTIVE The NEXCOPE NIB630 microscope is equipped with a quintuple nosepiece. A 4x planachromatic objective and one each of 10x, 20x and 40x planachromatic phase contrast objectives are included. The condenser has a numerical aperture of 0.3 and an extra long working distance. The objectives are calculated for a soil thickness of 1.2 mm. Please use appropriate culture vessels. The universal specimen holder is suitable for standard slides. EYEPIECES The eyepieces have a field of view of 22 mm. This gives you a very large field of view. The high eye point makes them very comfortable even for spectacle wearers. A rubber edge protects against scratches on contact. Dioptric compensation from -5 to +5 can be individually adjusted for each eyepiece. The interpupillary distance can be adjusted between 48 mm and 75 mm. The binocular can be tilted up and down to adjust the viewing height. ILLUMINATION The Koehler illumination provides the best possible light guidance of the microscopy light. This avoids stray light and only illuminates the just visible area in the specimen. This protects sensitive living specimens from excessive light irradiation. The powerful 3W LED can be adjusted in brightness and ensures optimal illumination. The brightness can be adjusted individually for each objective. If an objective is changed, the NEXCOPE NIB630 automatically adjusts the previously set brightness. The display shows the currently selected lens and the current brightness. The tiltable lighting unit makes it easier to work with taller sample vessels. The adjustable condenser with extra-long working distance enables quick readiness for use. MECHANICS In addition to coarse focusing, fine focusing helps to bring the specimen 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 friction of the coarse focusing can also be varied. The fine focusing knobs are held magnetically and can be mounted on the left or right. The XY stage offers the possibility of inserting various holders. This allows slides or even petri dishes to be inserted. CAMERA CONNECTION The NEXCOPE NIB630 is specially designed for use with C-mount cameras. The camera connection is located on the side and has a switch between visual observation and camera (100/0 or 0/100). You can choose from two different adapters, depending on the sensor size: 0.5x C-mount adapter 1x C-mount adapter (already included in the scope of delivery) ACCESSORIES (optional) Hoffman Modulation Contrast Relief 3D contrast Terasaki holder, Petri dish holder 54 mm and 90 mm Camera adapter for C-mount 0.5x FEATURES Professional inverted transmitted light microscope Type of objectives: infinity plan achromatic (60 mm adjustment length, M25) Precise mechanics Very bright illumination SCOPE OF DELIVERY Inverted transmitted light microscope 4x objectives, of which 10x, 20x and 40x as phase contrast objectives Filter slider for phase contrast Universal sample holder Centering telescope for phase contrast
