About these itemsHigh - magnification imaging: All microscopes use WF10X and WF25X eyepieces and 4X/10X/40X objectives. Magnification ranges from 40X - 2000X to 40X - 5000X, suitable for observing cell and tissue samples.Precise focusing: Feature dual coaxial coarse and fine focus knobs. Coarse adjustment lengths vary from 15mm - 20mm, and fine adjustment from 1.2mm - 1.3mm for smooth and accurate focusing.Optimal illumination: LED light sources combined with condensers (reflecting mirror or adjustable iris diaphragm) provide good illumination and contrast. Some have adjustable brightness.Complete STEM kits: Come with storage boxes and accessories like slides, petri dishes, etc., meeting STEM education standards for home, school, and extracurricular use.Versatile application: 360° rotatable viewing heads make them suitable for classroom teaching, home experiments, after - school activities, and parent - child interaction.Key Differencesxsp - 01A: Monocular, 40 - 2000X magnification, 15mm coarse adjustment, reflecting mirror condenser, fixed stage.H - 33A: Trinocular, 40 - 5000X magnification, 1.5 - megapixel electronic eyepiece, 18mm coarse and 1.2mm fine adjustment, mechanical stage.H - 20A: Binocular, 40 - 2000X magnification, Bluetooth photo capture, 18mm coarse and 1.2mm fine adjustment, adjustable LED illumination (bottom and top).XSP - 36 - 1000: Binocular, 40 - 5000X magnification, 195 achromatic objective lenses, 20mm coarse and 1.3mm fine adjustment, dual - layer metal stage.Specificationsxsp - 01AItem Model Number: xsp - 01APower Adapter: IncludedMagnification: Monocular, 40 - 2000XEyepieces: 2X, 10X, 25X; Objectives: 4X, 10X, 40XCondenser: Reflecting MirrorStage: Fixed, 9 x 9 cmLight Source: LEDFocusing: 15mm coarseViewing Head: Single fixed tubeMaterials: Aluminum alloy base, aluminum alloy + ABS plastic bodyDimensions: 4.3 x 6.3 x 11.6 in (110 x 160 x 295 mm)Net Weight: 2.12 lbs (0.96 kg ±5%)H - 33AItem Model Number: H - 33APower: Input AC 110 - 240V, 50/60Hz; Adapter: US plug, DC 5V/2A, 1000 - mm cableMagnification: Trinocular, 40 - 5000XEyepieces: 2 sets (2X, 10X, 25X); Objectives: 4X, 10X, 40X, 100XCondenser: Adjustable iris diaphragmStage: 95 x 95 mm, mechanical, 70 x 40 mm travelLight Source: LEDFocusing: 18mm coarse, 1.2mm fineViewing Head: 3 tubes, 360° rotatableMaterials: Aluminum alloy base, aluminum alloy + ABS plastic bodyDimensions: 5.5 x 7.5 x 13.3 in (140 x 190 x 338 mm)Net Weight: 4.9 lbs (2.22 kg ±5%)H - 20AItem Model Number: H - 20APower: Input AC 110 - 240V, 50/60Hz; Adapter: US plug, DC 5V/2A, 1000 - mm cableMagnification: Binocular, 40 - 2000XEyepieces: 2X, 25X; Objectives: 4X, 10X, 40XCondenser: Adjustable iris diaphragmStage: 95 x 95 mm, mechanical, 70 x 40 mm travelLight Source: Adjustable LED (bottom and top)Focusing: 18mm coarse, 1.2mm fineViewing Head: 2 tubes, 360° rotatableFeature: Bluetooth photo captureMaterials: Aluminum alloy base, aluminum alloy + ABS plastic bodyDimensions: 5.3 x 6.7 x 11.8 in (135 x 170 x 300 mm)Net Weight: 4.5 lbs (2.04 kg ±5%)XSP - 36 - 1000Item Model Number: XSP - 36 - 1000Power: Input AC 110 - 240V, 50/60Hz; Adapter: US plug, DC 5V/1A, 1200 - mm cableMagnification: Binocular, 40 - 5000XEyepieces: 2 sets (2X, 10X, 25X); Objectives: 4X, 10X, 40X, 100XCondenser: 1.25 NA with iris diaphragmStage: Dual - layer metal, 115x125 mm, 72x30 mm travelLight Source: Adjustable LEDFocusing: 20mm coarse, 1.3mm fineViewing Head: Binocular, 360° rotatable, 30° inclinedMaterials: Aluminum alloy & plastic bottom plateDimensions: 7.9 x 5.5 x 13.6 in (200 x 140 x 345 mm)Net Weight: 6.7 lbs (3.04 kg ±5%)Package Contentxsp - 01AUser ManualPhone Holder (Black PP)100 Cover Slips5 SlidesTest TubePetri DishStandard DropperDual Bulb DropperAir BlowerLens Cloth2 Absorbent Papers2 Lens Cleaning PapersAlcohol WipeCleaning GauzeTweezers3 Cotton SwabsDissecting NeedleSmall KnifeBrushMini ScrewdriverFill LightH - 33AUser ManualPhone Holder10 Specimens2 Cotton Swabs10 Slides100 Cover Slips (1 box)GauzeTweezersTest TubeDual Bulb DropperJam DropperLong DropperPetri Dish2 Dissecting NeedlesScrewdriverSmall KnifeBrushCedar OilH - 20AUser ManualPhone Holder (Black PP)100 Cover Slips5 SlidesTest TubePetri DishStandard DropperDual Bulb DropperAir BlowerLens Cloth2 Absorbent Papers2 Lens Cleaning PapersAlcohol WipeCleaning GauzeTweezers3 Cotton SwabsDissecting NeedleSmall KnifeBrushMini ScrewdriverFill LightXSP - 36 - 1000User ManualPhone Holder (Black PP)100 Cover Slips5 SlidesTest TubePetri DishStandard DropperAir BlowerLens Cloth2 Absorbent Papers2 Lens Cleaning PapersAlcohol WipeTweezers3 Cotton SwabsDissecting NeedleSmall KnifeBrushPower AdapterCedar Oil
