Comfortable high throughput routine microscopy:

The CX43 series of biological microscopes enables a comfortable seating position even during long periods of routine observation. The microscope stand is aligned to the anatomy of your hands and the optimal ergonomic position of the controls improves working efficiency. With the smallest movements, you can quickly set a sample with one hand whilst, with the other hand, adjust the focus and operate the stage. The microscope also has an optional camera port for digital imaging. 

Comfortable, High-Throughput Routine Microscopy

The CX43 microscope enable users to remain comfortable during long periods of routine microscopy observations. The microscope frame conforms to the user’s hands and the location of the control knobs maximize ergonomics to improve work efficiency. Users can quickly set a specimen with one hand, while adjusting the focus and operating the stage with the other hand with minimal movement. The microscope also features an optional camera port for digital imaging.

The CX43 universal condenser can handle a wide range of microscopy techniques and allows for future upgrades. Together with the nosepiece turret containing 5 objectives, multiple applications can be performed with a single microscope stand.

Uniform illumination with consistent colour temperature 

The CX43/CX33 LED illumination offers several advantages, both immediate and long-term: Daylight conditions, allowing specimens to be viewed in their natural colours. Consistent colour temperature at any brightness, so that no time is lost when you adjust the brightness. Long service life – 60.000 hours – with consistent brightness throughout the entire time.

Fixed Köhler illumination for comfortable viewing

The CX43 and CX33 microscopes have fixed Köhler illumination which provides the right level of illumination without having to adjust the condenser.

Comfort for extended usage

Ergonomically positioned focus knob

The low-positioned focus knob allows you to conduct your observations while your hands and forearms rest comfortably on the workbench. For observations at high magnification, the focusing stopper prevents a specimen from accidentally coming into contact with an objective.

Ergonomically designed stage and eyepieces

The CX43 and CX33 microscopes have features that ease long working hours in the lab:

• Lower stage position ensures more comfort and less fatigue
• Visibility of the stage from the viewing position, makes it easy to adjust and review specimens
• Fast and comfortable observation of specimens due to low and easily adjustable stage drive

Distortion-free images thanks to excellent optical properties

The CX43 microscope can be used with plan achromats that deliver sharp, distortion-free images for a wide field of view. Specimens can be viewed clearly and with uniform illumination during routine observations.

The CX43 is compatible with all UIS2 objectives.

Flexibility for a wide range of applications

The CX43 microscope is equipped with a standard universal condenser for a variety of microscopy methods:

• Brightfield
• Darkfield
• Phase contrast
• Fluorescence
• Simple polarisation

Magnification can be changed from 2X to 100X without needing to adjust the condenser lens.

Simple fluorescence observation

Fluorescence microscopy is simple and straightforward. Connect the compact fluorescent illuminator to the microscope stand and set the condenser turret to the FL position. The LED light source is pre-centred and has a long 60,000 hour life. Turn off the transmitted illumination by setting the condenser turret to the PL position to reduce the background noise caused by incidental light coming from the top of the condenser.

Viewing angle 30° Phototube: 50/50 Eyepieces: 10x/20 Condenser: Abbe rotary condenser NA 1.25 with positions for: Brightfield, darkfield (up to 40x), phase contrast, fluorescence (excitation with blue light), polarization (simple)

Dimensions (W×D×H): 211mm×376mm×393mm (standard configuration)

Weight: Approximately 7.3kg

Objectives are not included in the scope of delivery!

The CX43 universal condenser offers a variety of observation methods and future upgradability. In combination with the five-position revolving nosepiece, multiple applications can be covered using the single microscope frame.

Maintain Preferred Observation Conditions with Minimal Adjustments

Uniform Illumination with Consistent Color Temperature

The CX43 LED illumination provides several advantages, both immediate and over the long-term: Produces daylight conditions so specimens can be viewed with their natural colors Consistent color temperature at any brightness, so can avoid spending time making adjustments when you change the brightness A long 60,000-hour lifetime with the brightness level remaining stable throughout

Fixed Köhler Illumination for Comfortable Viewing

CX43 microscope provides fixed Köhler illumination, enabling you to achieve the right illumination without adjusting the condenser.

Remain Comfortable during Extended Usage

Ergonomically Positioned Focus Knob

The low-positioned focusing knob enables you to conduct your observations while keeping your hands and forearms in comfortable positions resting on the desk. When working under high magnification, the focusing stopper prevents a specimen from accidentally hitting an objective.

Ergonomic Stage and Eyepiece Position

CX43 microscope offers features that support you through long hours in the lab:

• Low-positioned stage to enhance comfort and reduce fatigue
• Stage visibility from the eye point position to enable you to smoothly set and check specimens
• Low stage knob that can be controlled with just a light touch, so you can quickly and comfortably view your specimens

Excellent Optical Performance for Flat Images

CX43 microscope can be used with plan achromat objectives, which provide clear images with high image flatness over a wide field of view. You can view specimens clearly with even illumination during routine observations.

The CX43 is compatible with all UIS2 objectives.

Flexibility for Multiple Applications

The CX43 microscope uses a standard universal condenser, offering a variety of observation methods:

• Brightfield
• Darkfield
• Phase contrast
• Fluorescence
• Simple polarization

You can change the magnification from 2X to 100X without moving the top lens on the condenser.

Simple Fluorescence Observation

CX43 Fluorescence observation is simple and easy. Plug the compact fluorescent illuminator into the microscope frame and set the condenser turret to the FL position. The LED light source is pre-centered and has a long, 60,000-hour lifetime. Shutter the transmitted illumination by setting the condenser turret to the FL position to reduce the background noise cause by incidental light coming from the top of the condenser.

Viewing angle: 30° Photo tube: 50/50 Eyepieces: 10x/20 Condenser: Abbe rotary condenser NA 1.25 with positions for: brightfield, darkfield (up to 40x), phase contrast, fluorescence (excitation with blue light), polarisation (single)
