XAB100 Laboratory Biological Microscope

The XAB100 is a laboratory biological microscope with a monocular, binocular, or trinocular inclined 30° observation tube, a quadplex nosepiece, and coaxial coarse and fine focusing knobs.

Product Overview

The XAB100 is a laboratory biological microscope with a monocular, binocular, or trinocular inclined 30° observation tube, a quadplex nosepiece, and coaxial coarse and fine focusing knobs. It supports 4x, 10x, 20x, 40x, 60x, and 100x objectives with oil immersion, and includes a 3WLED illumination system. The mechanical stage measures 125mmx115mm with 35mmx75mm travel, and the Abbe condenser has N.A. 1.25 with iris diaphragm. It is supplied with a plano-concave mirror and can be configured with optional accessories including dark field rings, polarizing attachments, and C-mount adapters.

Key Benefits

  • Inclined 30° observation tube reduces neck strain during prolonged use
  • Rotatable 360° head allows multiple users to view without repositioning
  • Coaxial coarse and fine focusing knobs with 22mm travel and 2μm scale enable precise focusing
  • Quadplex nosepiece holds six objectives, reducing the need to swap during inspection
  • 3WLED illumination system provides consistent, low-heat light without external power
  • Optional dark field ring improves contrast for transparent or low-contrast specimens
  • Polarizing attachment enables analysis of birefringent materials like crystals and fibers
  • C-mount adapter allows connection to digital cameras or recording systems
  • Mechanical stage with 35mmx75mm travel supports large slides and detailed scanning

Application Scenarios

  • Routine histology and cytology slide examination in clinical or research labs
  • Teaching microscopy in university biology or medical training labs
  • Quality control inspection of cell cultures, blood smears, and tissue sections
  • Material analysis of fibers, crystals, and thin films using polarizing attachments
  • Dark field observation of microorganisms, bacteria, or unstained specimens
  • Documentation of specimens with a digital camera via C-mount adapter
  • Use in labs with limited power access, thanks to the rechargeable 3WLED option

Who It Is For

  • Clinical and veterinary laboratories conducting routine microscopy
  • University and school biology teaching labs
  • Research labs in life sciences and medical diagnostics
  • Quality control departments in pharmaceutical and biotech companies
  • Material science labs requiring polarizing or dark field analysis
  • Field or mobile labs with limited electrical infrastructure

Problems It Solves

  • Fixed upright tubes cause neck strain during long inspection sessions
  • Lack of mechanical stage forces manual slide movement, increasing error risk
  • Inconsistent lighting from halogen lamps causes heat damage to sensitive samples
  • No C-mount adapter requires a separate camera system for digital documentation
  • Single objective nosepiece forces frequent swaps during multi-magnification work
  • Non-rotatable heads limit shared viewing in teaching or team settings
  • No dark field option reduces visibility of transparent or low-contrast specimens

Technical Features

  • Inclined 30° observation tube with 360° rotation for ergonomic viewing
  • Interpupillary adjustment 48-75mm for binocular/trinocular models
  • Coaxial coarse and fine focusing knobs with 22mm travel and 2μm scale
  • Quadplex nosepiece with six objective positions, including 100x/1.25 (Oil)
  • Abbe condenser with N.A. 1.25 and iris diaphragm for high-resolution imaging
  • Mechanical stage with 125mmx115mm size and 35mmx75mm travel range
  • 3WLED illumination system with stable, low-heat output
  • Rechargeable 3WLED option for use without mains power
  • C-mount adapter with 1x/0.5x magnification and focus adjustment
  • Plano-concave mirror for ambient light use
  • Optional dark field ring for 4x-40x objectives
  • Optional polarizing attachment with analyzer and polarizer

Comparison With Other Options

XAB100 with monocular headThe binocular and trinocular versions add dual-eye viewing and camera compatibility, while the monocular is simpler and lower cost.
XAB100 with halogen lampThe 3WLED system produces less heat, extends bulb life, and operates without mains power when rechargeable.
XAB100 without C-mountThe C-mount adapter allows direct connection to digital cameras, eliminating the need for a separate imaging system.

Use Guide

  • Adjust the interpupillary distance to 48-75mm before focusing to ensure a single merged image
  • Use the coarse knob first to bring the specimen into approximate focus, then fine-tune with the fine knob
  • For oil immersion, apply a drop of immersion oil to the 100x objective and clean it after use
  • Set the condenser iris diaphragm to match the objective's N.A. for optimal contrast and resolution
  • Use the mechanical stage to move large slides smoothly across the field of view
  • Connect a digital camera via the C-mount adapter for image capture and documentation
  • Switch to rechargeable LED mode in labs without stable power or in field settings
