"The revelations of the Microscope are perhaps not excelled in importance by those of the telescope. While exciting our curiosity, our wonder and admiration, they have proved of infinite service in advancing our knowledge of things around us" (Joseph Leidy)

Diatom Lab is the scientific laboratory company based in the North of Italy with the VAT number IT 01635810193 (Partita IVA 01635810193), the registered name DIATOM LAB di Stefano Barone, and placed under the classification “Research and development in the field of other natural sciences and engineering”.

Diatom Lab counts many important research centres, universities, colleges, environmental organizations and microscope companies from all around the world among its customers, in addition to hundreds of private customers of course. Just for example you can read the contract signed with the Italian National Research Council or CNR (https://www.cnr.it/en) by this link: http://www.urp.cnr.it/copertine/ente/ente_evidenza/gare_2018/ISASI_011_det.pdf The other numerous client companies from all over the world are not public bodies, therefore they cannot be listed here for privacy reasons, but you can read the almost a thousand 100% positive eBay feedbacks at the following link: eBay feedbacks In fact Diatom Shop sells its special products online (by email order) or more rarely through the business eBay page http://www.ebay.com/usr/diatomshop to promote the products to private customers (the eBay account name is diatomshop and starting prices are often symbolic as most bids happen in the final minutes or seconds of each auction. Almost every week Diatom Shop sells many very rare Diatoms on eBay).   

Diatom Lab performs the following activities:

1) Production of Microslides and Arrangements with Diatoms, Radiolarians and other microscopic objects for Optical Microscopy and Scanning Electron Microscopy (SEM), through new and never published techniques. Diatom Lab's microscope slides containing micromanipulated Diatoms and Radiolarians are made to last in time and are produced with absolutely Innovative, Modern, Never published, Unique, Professional Techniques and Formulas: the company initially started from the 19th century's amazing idea and then elevated it to the needs of the most modern and sophisticated microscopes!

2) Production of Test plates for Optical Microscopy (To obtain the PDF Instruction  Manual of the "Diatom Test Slide, Version 2.0", simply click on this link), through new and never published techniques.

3) Study and cleaning of the recent and fossil Diatoms / Radiolarians / Foraminifera / Silicoflagellates collected;

4) Production of unique mountants and unique fixatives for internal use:

Diatom Lab's self-produced mountants and fixatives are really INVISIBLE even in phase contrast, darkfield illumination and differential interference contrast (DIC)! Please notice the test in the photo gallery below performed by Purdue University Fort Wayne's scanning electron microscope (SEM) on Diatom Shop's microscope slides that contain Diatoms fixed by Diatom Lab's special fixative (without mountant and cover glass to permit SEM investigations)!

5) Photographic record of the species:

In Diatom Lab several research microscopes are used, such as the trinocular Zeiss Axio Imager.A2. It’s a top of the range Zeiss current research microscope… still made in Germany!
Click on the image below (Stefano Barone in a corner of Diatom Lab's laboratory) to download the pdf file with the Diatom Lab's Zeiss Axio Imager.A2 microscope configuration (objectives, condensers, etc.)

Its beam path is totally Apochromatic (IC2S = Infinity Contrast & Color Corrected System) and is enclosed in a stable cell that has been isolated from the rest of the stand and is thus particularly insensitive to outside thermal influences and vibrations. Zeiss Axio Imager.A2 has a 25 mm field of view and uses Zeiss M27 objectives, that have a bigger thread than the standard RMS objectives (27 mm versus 20.3 mm): in this way they capture much light, giving brighter and exceptionally spectacular images. Diatom Lab’s version weighs more than 40 Kgs, so is very stable for high resolution photomicrography and HD or 4K videos. Zeiss Axio Imager.A2 is a true jewel for serious study and documentation of Diatoms, Radiolarians and microscopic life in general. Diatom Lab's Zeiss Axio Imager.A2 is richly equipped to realize photomicrographs allowing several techniques such as Differential Interference Contrast (DIC), Phase contrast, Polarized light (even with Lambda plates), Dark field, Immersion Dark field, Bright field, Rheinberg Illumination, Epi-illumination and Epi-illumination in darkfield. Diatom Lan's Zeiss Axio Imager.A2 is accessorized with Zeiss M27 Plan-Apochromat and EC (= Enhanced contrast) Plan Neofluar objectives, and with Achromatic-Aplanatic condensers (mainly used in research, force the rays of light coming from the field diaphragm to intersect exactly in the plane of the object with a very high degree of correction, providing details of extreme precision and cleanliness).
Another excellent and modern research microscope is used in Diatom Lab, the Zeiss Axio Scope.A1, but as a back-up instrument for routine work;

6) Research and Invention of new substances for microscopy;

7) Research and Invention of new mounting techniques;

8) Science education;

9) Publication of articles and books on microscopy;

10) Quality, Quality, Quality
