Your Stereo Microscope with Integrated Illumination & Documentation

Stemi 508 is your robust all-rounder for everyday lab work in biology or industrial inspections. Observe, document and share your samples exactly as they are: rich in detail, sharp in focus and free from distortion or color fringes..

Profit from an easy-to-use microscope, where everything is integrated: long-life LED illumination, reflected and transmitted light and documentation.

Highlights

ZEISS Stemi 508's apochromatic zoom optics and efficient stray light suppression give you a crisp three-dimensional image, distortion-free, without color fringes.
Thanks to the low viewing angle of 35°, Stemi 508 is more ergonomic than any other Greenough-type stereo microscope.
Everything integrated into Stemi 508 stand K – no additional cables or boxes.
Easily select and mix the integrated LED illuminations (vertical and oblique reflected light, so as transmitted light).
Large working distance (92 mm) and object fields – examine whole samples and chips.
LED segmentable ring light for shadow free and homogeneous ring illumination and oblique light segment illumination: half circle, quarter circle, two-spot
LED spot K, zoomable and height adjustable, for oblique and grazing light illumination with strong shadow
Additional front optics available for varying the working distance and the object field.

Designed for Your Applications

Observe and identify biological samples in the classroom, and in the lab.
Inspect your molds and chips before and after microfabrication to identify possible defects.
Observe most of your chip with a large field of view of 36 mm and zoom in for more details.
For even larger samples, add interchangeable optics and observe an area of up to 122 mm.

Since Darwin Microfluidics sells exclusively to companies and institutions and is based in France, the VAT treatment for your orders depends on the location of your company or institution:

Within the EU (excluding France): For customers in other EU countries, the reverse charge mechanism applies. This means that VAT is not charged by us at the point of sale. Instead, it is your responsibility to account for the VAT at the standard rate applicable in your country under the reverse charge procedure. This process helps simplify cross-border transactions within the EU.

In France: For customers located in France, standard French VAT rates apply to all purchases. As a France-based company, we are required to charge VAT on sales to other French companies and institutions, which you can then reclaim according to local VAT procedures if applicable.

Outside the EU: For customers outside the European Union, sales are not subject to VAT by us. However, you may be subject to import duties, taxes, and charges that are not included in the item price or shipping cost. These charges are the buyer's responsibility and vary by country. We advise checking with your local customs office for more information.

Please ensure your VAT identification number is provided during the ordering process for EU transactions to qualify for the reverse charge mechanism. If you have any questions regarding VAT charges or need further assistance with VAT-related issues, please contact our customer service team.

We are unable to provide specific estimates for customs fees, duties, or taxes associated with your order. These charges are determined by the customs authority in your country and can vary based on a variety of factors, including the type of items purchased, their value, and the country to which they are being shipped.

We recommend contacting your local customs office directly to get the most accurate and up-to-date information regarding potential customs charges for your order. They can provide you with detailed guidelines on the fees you might expect to pay based on the products you're importing from us.

Please remember, these charges are the responsibility of the recipient and are not included in the shipping costs paid to Darwin Microfluidics.
