RX50 Research Medical Biological Microscope

The RX50 is a research and clinical biological microscope with a 10X eyepiece and a 40X objective, supplied on a standard stand with a 150mm working distance.

Product Overview

The RX50 is a research and clinical biological microscope with a 10X eyepiece and a 40X objective, supplied on a standard stand with a 150mm working distance. It provides 400X magnification with a 0.65 numerical aperture objective, suitable for routine histology, blood smear analysis and microbiological culture inspection in clinical and teaching labs. The infinity optical system ensures consistent image quality across the magnification range.

  • IlluminationLED, adjustable brightness
  • Focus systemCoarse and fine focus
  • MountingStandard stand
  • Power supplyBuilt-in LED illumination

Key Benefits

  • 150mm working distance allows room for a pipette, slide holder or specimen container under the objective
  • Infinity optical system delivers sharp, flat images across the field at 400X and higher magnifications
  • 40X objective with 0.65 NA provides sufficient resolution for blood cell counting and bacterial colony detail
  • 10X eyepiece with 18mm field of view supports comfortable long-term observation
  • Standard stand with coarse and fine focus enables stable operation on a lab bench or teaching table

Application Scenarios

  • Routine blood smear analysis in a clinical laboratory with a 400X magnification requirement
  • Microbiological culture inspection for colony morphology and growth patterns
  • Histology section examination in a teaching lab with students using the same instrument
  • Water quality testing using sediment or plankton samples under a 400X magnification
  • Teaching students to identify cell structures in prepared slides with consistent focus and illumination

Who It Is For

  • Clinical laboratories performing routine blood and tissue analysis
  • University and school biology teaching labs for cell and microorganism observation
  • Research labs conducting basic microbiology and histology work
  • Veterinary clinics for parasite and blood sample screening
  • Public health and environmental testing labs for water and soil sample inspection

Problems It Solves

  • Short working distance microscopes make it difficult to manipulate slides or pipettes under the objective
  • Fixed magnification systems require multiple instruments for different sample types
  • Non-infinity optical systems introduce image distortion at higher magnifications
  • Lack of standard focus controls leads to inconsistent results between users
  • Inadequate field of view forces frequent repositioning during slide scanning

Technical Features

  • Infinity optical system with a 40X objective and 0.65 NA for consistent image quality
  • 10X eyepiece with 18mm field of view for wide-angle observation
  • 150mm working distance between objective and specimen stage
  • Coarse and fine focus controls on the standard stand for precise focusing
  • Standard 150mm mechanical stage with slide holder for stable specimen positioning
  • Revolving nosepiece with 4 positions for objective change without recentering
  • Built-in 360° condenser with adjustable aperture diaphragm for contrast control
  • LED illumination with adjustable brightness for consistent lighting across samples

Customization Options

  • Optional 10X eyepieces with different field numbers for wider or narrower viewing
  • Additional objectives from 10X to 100X to extend magnification range
  • Optional condenser with phase contrast capability for transparent specimens
  • Replacement of standard stand with a larger or articulated stand for ergonomic use
  • Addition of a camera adapter for digital imaging with a C-mount camera

Comparison With Other Options

RX50 without 40X objectiveThe standard RX50 includes a 40X objective; the version without it limits magnification to 100X, reducing resolution for fine cellular detail.
RX50 with 10X objective onlyThe RX50 with 40X objective provides 400X magnification, suitable for blood and microbiology work; the 10X-only version is limited to 100X and not suitable for detailed cellular inspection.
Digital biological microscope with LCD screenThe RX50 provides a traditional optical view with a stable mechanical stage and focus; a digital screen-only model lacks tactile feedback and may introduce lag in real-time observation.

Use Guide

  • Adjust the interpupillary distance of the eyepieces to match your eye spacing before focusing
  • Start with the coarse focus at low magnification, then switch to fine focus at 400X for sharp detail
  • Use the condenser aperture diaphragm to control contrast - open for brightfield, close for higher contrast
  • Ensure the slide is properly secured on the mechanical stage before focusing to avoid damage
  • Clean the objective and eyepiece lenses with lens paper after each use to maintain image clarity
