This model features both transmitted and incident illumination which is perfect for both brightfield and fluorescence applications. One model is available for phase contrast applications and comes with a Zernike-style phase contrast condenser with annulus rings. All models come standard with quadruple reversed nosepiece with positive click stops. The viewing head is Seidentnopf and all models come trinocular for either photo or video capabilities. There is a slide out main prism that facilitates maximum light through the head. All models have a graduated mechanical stage with 30 x 70mm movable range. The focusing mechanism is coaxial for precise focusing control. The upper illumination system is 100W HBO with a mercury light source and the lower illumination system is 6V 20W variable halogen (supplied with blue, green and neutral density filters). The model for phase contrast has a centerable field diaphragm for Kohler illumination.
Item # 1286ECM Fluorescence Microscopes, Intermediate Level - 1200ECM Series
VanGuard 1200ECM Series Fluorescence Microscopes provide the necessary specifications for diagnostic & educational use in medical/veterinary clinics, universities, and industrial laboratories.
Viewing Head: Trinocular (Seidentopf) heads rotate 360° and are inclined at 30°. Both models feature interpupillary and dioptric adjustment. The heads feature a sliding main prism (100/100 split) to provide either 100% of the image to the vertical Tube, or 100% of the image to the eyepieces.
Eyepieces: 10X Widefield (DIN) with a field number of 18.
Nosepiece: Quadruple, reversed, ball-bearing nosepiece with high-grade lubricant and positive stops. The nosepiece is reversed (inward-facing) to allow for easier manipulation of slides and to aid in keeping the objectives clean.
Objectives: Achromatic fluorescence objectives come standard on both models. Model 1282ECM features plan achromatic brightfield objectives. Model 1286ECM features plan achromatic phase contrast and brightfield objectives. All objectives are made to DIN standards and are coated.
Stage: Delivering a high level of fluid motion control and longevity, the stage measures 160 x 140 mm. Features a removable spring-clip slide holder and a chemical-resistant finish. Motion is controlled by a right-hand, low-position coaxial control and is driven by a rack and pinion system.
Focusing Movement: Coaxial, low-position coarse and fine focus controls feature a 40 mm focusing range and are graduated to 2 microns per division. Fitted with tension adjustment and safety auto stop.
Condenser: Model 1282ECM comes with a 1.25 N.A. Abbe condenser. Model 1286ECM comes with a 1.25 N.A. Zemike condenser with phase annulus rings for 10X, 20X, 40X, & 100X; also has a "0" setting for brightfield work. All condensers are mounted on a rack and pinion focusing mechanism and feature spring-loaded centering knobs and an iris diaphragm with a swing-in filter holder.
Lower Illumination: 20 W variable quartz halogen light source. Comes with blue, green (Model 1286ECM only), and dispersion filters. 0.5 A, 250 V fuse.
Upper Illumination: Features a 100 W HBO mercury light source which is mounted to the rear and is protected by a sturdy, all-metal housing. External power supply provides constant, even light. 5.0 A, 250 V fuse.
Fluorescence Filters: Features a 3-position (2 filter positions and 1 OFF position), sliding, filter cube assembly. Fluorescence models come standard with 2 broad band filters (blue & green).
Base: Stable 250 x 200 mm base fitted with anti-skid rubber feet
Body: Cast-metal, ergonomic body with stain-resistant enamel finish.
Dimensions: 250 mm (L) x 200 mm (W) x 435 mm (H); 8.8 kg.
