ZEISS Stemi 305, configured for microfluidics devices inspection.
Compact stereo microscope with true 3D viewing, 5:1 zoom (8x to 40x), and flexible LED illumination options. Ideal for fast daily observation of microfluidic chips and parts, and for easy documentation with a camera. Camera not included.
General
Your stereo microscope for daily chip checks
Stemi 305 is a compact Greenough stereo microscope with a 5:1 zoom range. It lets you observe samples as they are, in real 3D, distortion-free and crisp in contrast, with minimal setup. This configuration is practical for microfluidics, where quick visual checks of chips, channels, connectors, and assemblies matter.
The K EDU stand provides a stable working area. The included LED illuminators help you tune lighting to the surface you want to inspect, from general viewing to highlighting defects.
Typical microfluidics uses
- Inspection of microfluidic chips before experiments (channel cleanliness, debris, damage)
- QC checks during fabrication or assembly (bonds, interfaces, alignment)
- Observation of connectors, tubing interfaces, and chip fittings
- Surface inspection and defect detection using segmentable ring illumination
Key features
Fast to set up, comfortable to use, and easy to document.
True 3D viewing with 5:1 zoom
Zoom from 8x to 40x to move quickly from an overview of the chip to a detailed inspection of features and interfaces.
Lighting that reveals defects
Use the double spot to shape contrast and the segmentable ringlight to enhance edges and reveal scratches or surface marks.
Stable K EDU stand
A robust bench stand with a comfortable working area and integrated power, designed for daily use and repeatable positioning.
Documentation-ready (trinocular)
The trinocular body makes it easy to add a camera for capturing images and videos for reports, training, or QC documentation.
