(
You can download PDF file by clicking here).

Diatoms and Radiolarians are microscopic, jewel-like products of nature but they must be prepared with the best  techniques, tools and materials in order to admire them in all their full glory!
Diatom Lab preparations can be observed and admired even with a modestly priced microscope (contrast enhancement techniques such as phase contrast, darkfield illumination and differential interference contrast are not strictly necessary) thanks to Diatom Lab's strict quality procedures!
DIATOM LAB Premium quality microscope slides are manufactured in our own laboratory under rigorous scientific control! Only the best glasses are used: Custom optical quality cover glasses and 26 x 76 mm (1 x 3 inch) fine microscope slides with ground edges.
DIATOM LAB keeps MANY THOUSANDS OF DIFFERENT
recent / fossil / subfossil / marine / freshwater DIATOM SPECIES within the laboratory to offer unique and customized products!
We safely SHIP WORLDWIDE: all parcels are fully tracked, so that you can check the progress of your items through to delivery!
Payments are accepted with PayPal (no PayPal account needed, just enter your card details) or bank transfer.
Our clients and reputation:
Diatom Lab counts many important research centres, universities, colleges, environmental organizations, and microscope companies from all around the world among its customers, such as the Cold Spring Harbor Laboratory (New York), the Rockefeller University (New York), the Eastern Washington University (Washington), the University of South Bohemia České Buděovice (Czech Republic), the Italian National Research Council or CNR, the Gymnase de Morges (Switzerland) and the World Wildlife Fund (WWF), in addition to many private customers who purchase our diatom preparations. Click here and  here for the contracts signed with the Italian National Research Council or CNR (https://www.cnr.it/en). Other clients are not public bodies, therefore cannot be listed here for privacy reasons. For feedback from private customers about our diatom preparations, please see our 100% positive eBay feedback on thousands of transactions: Diatom Lab eBay Shop. Diatom Lab sells products online or, less often, through our business eBay page to promote our products amongst private customers. They wrote about us: Bulletin of the Quekett Microscopical Club, Nov 2019, No.77, ISSN 1350-9128, pp 22-25: the article recognizes Diatom Lab preparations as expertly-prepared and three microscope images of our slides have been published, such as a detail of the Diatom Test Slide version 2.0 with the commentimage chosen by editor to show the incredible resolution of this excellent slide”; Walker D., Exploring the Diatom Lab prepared slide of an integrated circuit chip, Micscape Magazine, April 2020,  Issue 289, ISSN 1365 - 070x: "The slide is impeccably prepared / mounted","In my view the slide is excellent value for money and maintains the high standards set by the Diatom Lab shop (I have a number of the diatom slides)"
Diatom Lab works with honesty, accuracy and transparency. You'll always receive a proper invoice with every purchase.

SELECTED AND MICROMANIPULATED DIATOMS: MICROSCOPE SLIDES (Science, Art, Technology & Innovation by Diatom Lab)
All prices include taxes and fees. Worldwide shipping by registered international parcel is always 10,90 euros, no matter how many items are in the cart!

COMPARISON SLIDE: microscope slide of selected, micromanipulated Pennate + micromanipulated Centric Diatom with SPECIES LIST printed on the label

COMPARISON SLIDE: microscope slide of selected, micromanipulated Pennate + micromanipulated Centric Diatom with SPECIES LIST printed on the label

COMPARISON SLIDE: microscope slide of one micromanipulated Pennate Diatom (bilaterally symmetric) and one micromanipulated Centric Diatom (radially symmetric), mounted in the excellent Diatom Cubed mountant (refractive index > 1,7). See example in DIC on the side.
Only the best, cleanest, unbroken specimens are hand selected! All Micromanipulated Diatoms are guaranteed to be fixed directly to the UNDERSIDE of the custom optical quality cover glass (and not, as is common, on the microscope slide) for maximum resolution and contrast! The reason for this: microscope objective performance drops quickly noticeably as the specimen distance from the cover glass increases. Microscope objective lenses are designed to be optimally corrected for objects located immediately below the coverslip!

Diatom Test Slides are extremely useful to:
A) compare objectives, condensers, microscopes and optical microscope illumination techniques such as bright field, oblique illumination, differential interference contrast (DIC), phase contrast, dark field, polarized light, Rheinberg illumination and Hoffman modulation contrast!
B) practice using your microscopes at their highest levels!
C) determine the resolving power of your microscope (the resolving power of a microscope is measured by its ability to differentiate two lines or points in an object)!
D) examine the variations in contrast and resolution by regulating the condenser aperture diaphragm
E) understand the importance of correction collar for minimazing spherical aberration
F) examine the variations in resolution by using different wavelengths of light
These Test microscope slides are standardized, in fact each microscope slide has the same production characteristics, please read the important Technological innovations in the Home page. Mounmted in Diatom Cubed mountant (refractive index > 1,7)!

ARRANGED MICROSCOPE SLIDES of DIATOMS FORMING WORDS, INITIALS or LETTERS! Click this link for a bigger image. A unique gift for you or your loved ones! You can ask for your customized arrangement!  (Science, Art, Technology & Innovation by Diatom Lab)
Only circular diatoms of the same species - Paralia sulcata (Ehrenberg) Cleve - are selected and perfectly micromanipulated!
Each diatom has a diameter of about 30 µm and the letters  are visible only under a light microscope!
Diatom Lab's special techniques and Diatom Cubed mountant ensure that diatoms will never change their original position during shipping or storage. In other words, you will never see "floating" diatoms!
All prices include taxes and fees. Worldwide shipping by registered international parcel is always 10,90 euros, no matter how many items are in the cart!

Customized High-end Diatom Arrangements. Mounted in the excellent Diatom Cubed mountant (refractive index > 1,7). Only the best, cleanest, unbroken specimens are hand selected! All Micromanipulated Diatoms are guaranteed to be fixed directly to the UNDERSIDE of the custom optical quality cover glass (and not as-is common, on the microscope slide) for maximum resolution and contrast! The reason for this: microscope objective performance drops quickly noticeably as the specimen distance from the cover glass increases. Microscope objective lenses are designed to be optimally corrected for objects located immediately below the coverslip!
