MAIN PRODUCT LIST -  last updated on September 2018


Diatom Lab (Diatom Shop) has greatly improved the nineteenth-century procedures of arranging Diatoms and other microscopic objects in order to meet the high requirements of the most modern and sophisticated microscopy (please read some of the technical informations in the home page). The company offers STATE-OF-THE-ART MICROSCOPE SLIDES produced using the INNOVATIVE, NEW, NEVER PUBLISHED, UNIQUE, PROFESSIONAL, MODERN, LATEST DIATOM LAB'S TECHNIQUES AND FORMULAS! (PLEASE READ SOME OF THE TECHNICAL INFORMATIONS IN THE HOME PAGE) You'll have the BEST CONDITIONS FOR EXCELLENT RESOLUTION AND CONTRAST, for example Diatom frustules are attached / fixed to the UNDERSIDE of a PROPERLY THICK COVER GLASS (and not commonly on the microscope slide!) having HIGH OPTICAL QUALITY, although this procedure requires special manufacturing precautions! Furthermore, mounting to the underside of the cover glass permits to easily use oil immersion objectives too (even those with very short free working distance, such as 63x/1,4 or 100x/1,4) as there is no space between diatoms and cover glass!

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. 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).  Please read more than a thousand 100% positive eBay feedbacks at the following link: eBay feedbacks . The company receives a lot of emails and letters of appreciation by direct customers too!

Diatom Lab was created to show the beauty, importance and power of microscopic nature to amaterus and scientists during an era of many superficial values. Diatom Shop's products require much accuracy, precision and time during (and before) their realization: although Diatom Lab works with the latest techniques, mountants and research microscopes, it doesn't differ much from a Nineteenth-century scientific laboratory company, so your purchase will help to keep this ancient craft still alive today!

Before payment you will always receive an email with attached the photographs and photomicrographs of the products you've ordered: WHAT YOU SEE IS WHAT YOU GET!

Diatom Lab works with honesty, accuracy and transparency. You'll always receive a paper INVOICE (if you are a business company) or a paper TAX RECEIPT (if you are a private customer) with every purchase!


All parcels are FULLY TRACKED, so that you can check the progress of your items through to delivery. Diatom Lab (Diatom Shop) safely ships WORLDWIDE using microscope mailer cases, bubble wrap and paddled packages: customers of Diatom Lab (Diatom Shop) live in USA, Europe, Asia, Oceania and Africa!


Payments are possible using PayPal (no PayPal account needed, just a credit card!) or bank transfer!

These products are extremely useful to
1) practice using your microscopes at their highest levels!
1) 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)
2) examine the variations in contrast and resolution by regulating the condenser aperture diaphragm
3) understand the importance of correction collar for minimazing spherical aberration
4) 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

Viewed with SEM, the average distance between areolae is 0,14 µm.
The theoretical limit of resolution of most light  microscopes  is
~ 0.2 μm, but these areolae can be detected by the techniques below, thanks to Diatom Cubed high refractive index mountant!
Recommended microscope objectives: oil-immersion 63 or 100x objectives having a very good or excellent numerical aperture (1,3 or 1,4)
Suggested techniques: Double immersion = Oil immersion objective and Oil immersion condenser in: Polarized light (the polarizers should be oriented perpendicular to each other = maximum level of extinction) with possibly oblique illumination; or Immersion dark field condenser (better 1,2/1,4) with Polarized light (the polarizers should be oriented perpendicular to each other = maximum level of extinction)
As always, Diatom is attached / fixed to the underside of a properly thick cover glass (and not commonly on the microscope slide!) in order to ensure the best conditions for excellent resolution and contrast! The customized cover glass (coverslip) with high optical quality is manufactured in Germany specifically for Diatom Lab. In Diatom Cubed mountant!
