Levenhuk Microscópio 400B Binocular - 75420

Levenhuk 400B Binocular MicroscopeMagnification: 40–1000x. Binocular head, achromatic objectives, LED light with a collectorLevenhuk 400B is a binocular laboratory microscope for professional work for a microbiologist, medical worker, veterinarian, ornithologist, ecologist, or biochemist. This universal model can be used for bright field research as well as for research using oil immersion. This microscope features a reliable metal body, high-quality achromatic optics and bright LED light with a collector.A binocular head is optimal for lengthy work with a microscope as it reduces eyestrain. It can be rotated 360° around its axis; a visual part is inclined at 30°. Wide-field eyepieces provide 10x magnification; achromatic objectives come pre-installed in a revolving nosepiece: they provide 4x, 10x, 40x, and 100x magnification. Total microscope magnification varies in the range from 40x to 1000x. The 40xs and 100xs objectives are equipped with protective spring-loaded frames of the front lens. A 100xs objective can be used for oil immersion.The stage is equipped with a mechanical scale; under the stage there is an Abbe condenser with an iris diaphragm and a filter holder. Below, there is a lighting unit: an LED light with a collector. The light brightness is adjustable. Due to rechargeable batteries (included), this microscope can be used without a power supply.Features:Binocular laboratory microscope, rotatable angled headObservations in the bright field in incident light, oil immersionAchromatic wide-field optics, magnification from 40x to 1000xLED light with a collector and brightness adjustmentMetal body, standard eyepiece barrel diameterPower supply is variable: by batteries or AC power supplyThe kit includes:Microscope4x, 10x, 40xs, 100xs (oil) achromatic objectivesWF10x/18mm eyepieces (2 pcs)Abbe condenser N.A. 1.25 with an iris diaphragm and a filter holderRechargeable AA batteries (3 pcs)Charging power cordVial of immersion oilFilters: blue, green, yellowDust coverUser manual and lifetime warranty Specifications:Head: binocular, rotatable 360°, inclined 30°Optics material: optical glassMagnification, x: 40–1000Eyepiece tube diameter, mm: 23.2Eyepieces: WF10x/18mm (2 pcs)Objectives: achromatic: 4x, 10x, 40xs, 100xs (oil)Revolving nosepiece: 4 objectivesInterpupillary distance, mm: 48–75Stage, mm: mechanical double-layer, 115x110mm, with a mechanical scaleStage moving range, using focusing mechanism, mm: 55/20Eyepiece diopter adjustment, diopters: ±5Condenser: Abbe condenser N.A. 1.25 with an iris diaphragm and a filter holderDiaphragm: irisFocus: coaxial, coarse (12mm) and fine (0.002mm)Body: metalBacklight: LEDBrightness adjustment: yesPower source: 110–220V via an AC power supply or 3 rechargeable AA batteries, 1300mAh, 1.2V; work time: 4 hours, charging time: 3 hoursLight source type: with a collector, 1W LEDFilters: blue, green, yellowUsage: General use product.
