Purchase Cheap! 40x-1000x Biological Binocular Compound Microscope
40x-1000x Biological Binocular Compound Microscope 
This is a brand new, factory sealed, Variscope Series 8621 microscope. The Variscope microscope family of optical instruments is made by one of the largest "private label" optical component fabricators in the world. Included with the quadruple nosepiece are four achromatic multi-coated objective lenses that display a true-color image. You get 4x, 10x, spring loaded 40x, and spring loaded oil immersion 100x objectives included with this microscope. For viewing, we provide a pair of premium grade wide-field 10x (18mm) eyepieces. This allows for magnification ranges of 40x, 100x, 400x and 1000x. Ergonomic features include an advanced Seidentopf-type microscope head to provide maximum comfort in adjusting interpuplillary distance. The microscope head swivels 360 degrees and sits at a 30 degree incline. The eyepieces have diopter focusing adjustments. The independent coarse and fine focusing knobs are on both the right and left side of the instrument. Unlike most cheaper models on the market that have simple slide clips, this microscope has a 115mm x 125mm stage with a fully mechanical X-Y axis slide holder. With this functionality, you can easily move the slide around on the stage with fine precision, no fumbling the slide under the clips. There is a graduated scale printed on the slide holder to allow you to maintain a record of the location of various structures on a particular slide. This microscope has a built-in 20 watt halogen bulb, with adjustable intensity light controls. Beware of cheaper models that use a tungsten bulb or have a simple on/off switch with no brightness controls. The microscope has a built-in spiral-type N.A. 1.25 Abbe condenser under the stage with an iris diaphragm. This advanced condenser gives you incredible control over the amount and focal length of light aimed at your specimen and is critical for high-powered magnification viewing. A swing-out filter holder is included as are a set of blue and green viewing filters.
