CX40 Teaching Lab Biological Microscope
The CX40 Teaching Lab Biological Microscope is a standard biological microscope designed for classroom and laboratory instruction.

Product Overview
The CX40 Teaching Lab Biological Microscope is a standard biological microscope designed for classroom and laboratory instruction. It features a fixed 40X to 400X magnification range using a 10X eyepiece and 4X, 10X, and 40X objectives, with a 160mm tube length and a 100mm working distance under the 4X objective. The microscope uses a 12V 20W halogen lamp for consistent illumination and includes a 360-degree rotating nosepiece with a built-in diaphragm for adjusting light intensity. It is supplied with a 100mm stage and a mechanical stage for precise slide positioning.

Key Benefits
- 40X to 400X magnification range covers most common biological specimens in teaching labs
- 100mm working distance under the 4X objective allows room for slide manipulation and staining
- Mechanical stage with 75mm x 50mm travel enables accurate slide positioning during observation
- 360-degree rotating nosepiece with built-in diaphragm lets students adjust light without changing components
- Fixed tube length of 160mm ensures compatibility with standard biological objectives and eyepieces
Application Scenarios
- Classroom instruction in high school or university biology labs using prepared slides
- Student-led observation of plant cells, animal tissues, and microorganisms under controlled lighting
- Laboratory sessions requiring consistent magnification and repeatable focus across multiple students
- Teaching sessions where multiple students take turns using the same microscope without recalibration
- Basic histology and cytology labs where slide positioning and lighting control are essential
Who It Is For
- High school and university biology teaching laboratories
- Science departments in secondary schools and vocational colleges
- Educational institutions running hands-on microscopy sessions
- Instructors who need a reliable, low-maintenance microscope for group use
- Training centers teaching basic biological observation techniques
Problems It Solves
- A fixed magnification range prevents the need for frequent objective changes during a lesson
- The 100mm working distance avoids interference from hands or tools when handling slides
- Mechanical stage ensures consistent slide positioning across multiple users
- Built-in diaphragm allows quick light adjustment without replacing components
- Fixed tube length eliminates focus drift when switching between objectives

Customization Options
- Option to replace the standard 10X eyepiece with 5X, 15X, or 20X eyepieces
- Optional 100mm stage with larger travel or different clip types
- Replacement of the halogen lamp with an LED version for lower heat and longer life
- Addition of a digital camera adapter for USB connection to a computer
- Supply of extra objectives or eyepieces as spare parts
Comparison With Other Options
| CX40 without mechanical stage | The CX40 with mechanical stage allows precise slide positioning, reducing the need for manual adjustment during observation. |
|---|---|
| CX40 with 100mm stage only | The standard 100mm stage with spring-loaded clips holds slides securely; the mechanical stage adds controlled movement for detailed scanning. |
| CX40 with LED illumination | The standard halogen lamp provides bright, consistent light; the LED version reduces heat and power use but may require a different adapter. |
Use Guide
- Adjust the interpupillary distance between 55mm and 75mm before focusing to avoid eye strain
- Start with the 4X objective and focus using the coarse knob, then switch to higher magnifications using the fine knob
- Use the mechanical stage to move the slide in small increments for detailed examination
- Adjust the diaphragm in the nosepiece to control light intensity based on specimen transparency
- Ensure the lamp is connected to a 12V DC power supply before turning on the illumination
