Enjoy the micro jewels of the sea. Welcome to Radiolarian Shop, an online store of Diatom Lab laboratory company! Radiolarians (Radiolaria, Mȕller 1858) are marine protozoa that form part of the zooplankton: they possess such intricate and elegant mineral skeletons that since their discovery, they have aroused a lot of interest on the part of collectors, scientists, researchers, microscopists, nature lovers and artists from all over the world. They are found throughout the global ocean, but fossil species (all microfossils, given their very small size) also existed and belong mainly to the Polycystines group: their siliceous skeletons can be found in some sedimentary rocks and marine sediments. In Diatom Lab laboratory we have many samples from both the sea and rocks.
Let's start your collection of beautiful, rare specimens from many parts of the world! You don't need a microscope to observe them, in fact - in case you buy the ones dry mounted on a opaque background - they can also be admired through a powerful magnifying glass (from 15x magnification and up)! We sell a large variety of professionally prepared Radiolarians to be observed through magnifying glass, stereo microscope, light microscope and scanning electron microscope (SEM): check out our catalog below! Diatom Lab offers meaningful products that exude science, art and culture: we are against superficiality and superficial objects.

If If you are an institution or company and need an official quote in PDF format, please contact us and provide all the necessary data.Diatom Lab produces prepared microscope slides of the highest quality: our laboratory stands out for the use of unique cutting-edge materials, technologies and procedures. For further information please visit the pages "Innovative preparations" and "Diatom Lab. Clients and reputation".
We produce microscope slides for many important microscope manufacturing companies, government agencies, universities, laboratories, researchers and scientists, but also private individuals and amateurs are welcome: our materials and techniques are therefore not amateur and require cutting-edge, expensive instrumentation that goes beyond that used by a average, non-specialized laboratory. All our products are made in our internal laboratory. Our proprietary high refractive index mountants are not for sale as they require additional specific procedures and tools to be used.
Important informations. We offer two product categories that have different characteristics:
1) microscope slides of selected, micromanipulated Radiolarians (where art meets advanced technology and innovative materials); 2) strew Radiolarians slides = microscope slides of strewn, unselected Radiolarians. Strew slides reveal the complex beauty of a natural sample at a glance. Along with several beautiful and intact specimens, you may also find broken or otherwise imperfect specimens: this happens not because our laboratory procedures, but because the majority of samples found in nature have these characteristics. Our stew slides are of the highest quality and are made with innovative materials, as can be seen from our more than a thousand 100% positive feedbacks. If you wish to purchase preparations containing 100% perfect specimens, please buy our microscope slides of selected, micromanipulated Radiolarians, which you can also find in this price list.
"The revelations of the Microscope are perhaps not excelled in importance by those of 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); “Rerum natura nusquam magis quam in minimis tota est” = “Nature is nowhere as great as in its smallest works” (Pliny the Elder).

MICROSCOPE SLIDES OF STREWN RADIOLARIANS DRY MOUNTED ON A OPAQUE BACKGROUND (WITHOUT COVER GLASS). Intended for powerful magnifying glasses (from 15x magnification and up), stereo microscopes and optical microscopes in reflected light or with an external side lighting source. The absence of a cover glass slide allows these slides to be observed by means of reflected light microscopy (epi-illumination or metallurgical microscopy), in which the sample is illuminated from above through the objective. Enjoy the Radiolaria safari! To create these products, we selected two extremely rare and antique samples that contain some of the largest specimens in the world, which are therefore more easily observable: they come from two locations frequently cited in the Nineteenth century scientific literature.Each microscope slide contains strewn Radiolarians in abundance. Since in this case Radiolarians are not protected by cover glass: a) do not touch the center of the microscope slide to avoid damaging them; b) to prevent dust from settling, after observations store the slide in the mailer case that will be sent to you.
MICROSCOPE SLIDES OF SELECTED, MICROMANIPULATED RADIOLARIANS (WITH COVER GLASS) mounted in high refractive index Prime Mountant. Intended for optical microscopes and stereo microscopes. All micromanipulated Radiolarians 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 cover glass! All Radiolarians are mounted in Prime Mountant (excellent high refractive index medium).

“Délicates constructions où la grâce s'allie à la solidité, les carapaces siliceuses, à claires-voies, des Radiolaires [...] nous apparaissent comme de minuscules palais de verre ou de béton, réalisés par des architectes à l'imagination fertile”. Laporte L-J. (1949), Panorama du micro-monde, Paris.
“I più complicati lampadari in ferro battuto che i più abili artefici hanno mai costruito, i più accurati ed ornamentati gioielli in filigrana che l'arte degli orafi abbia mai prodotti, le più meravigliose opere di traforo e di cesello che siano mai state pensate nella mente più immaginosa ed eseguiti dalle mani più pazienti, non reggono al confronto degli ornamentali scheletri dei microscopici Radiolari, di cui pure gli uomini, nei loro tentativi per la ricerca del bello geometrico, non hanno fatto altro che ripetere inconsapevolmente le forme”. Colosi G. (1948), Le meraviglie del mare, Torino.
“Few microscopic objects are more beautiful than an assemblage of the most remarkable forms of the Barbadian Polycystina, especially when seen brightly illuminated upon a black ground”. Carpenter W. (1857), The microscope and its revelations, London.
“One cannot look at these Radiolarians without noticing the striking resemblance which many of their forms bear to objects artistically wrought by man. We find architectural decorations, vases in a multiplicity of forms, devices suggestive of jewel-work, cups, balls, lamps, etc., etc. Man cannot have copied his ideas from these objects, because he made such things long before any microscope was constructed which could reveal them to his vision. On the other hand, the microscopic creatures could not have imitated man. In fact, their beautiful shells and skeletons grew long ages before man’s appearance on this earth. Whence then comes this parallelism of design? The question is worth a moment’s consideration. Before answering the question, or suggesting what may be an answer, let us see if the student of the microscope has found in any other department ot microscopic life than the Radiolarians, any similar parallelism of design. He will tell us that he is constantly meeting with objects that are exceedingly minute, which bear the closest resemblance to objects used in the arts, in science, in trade, and in domestic life - that this is a special feature in microscopy which attracts the attention of every student. The answer then that must suggest itself is, that the human mind, in this respect, is a faint reflection of the Divine mind. What other answer can we give ? We may enter into deep theories and learned reasons, which may only bewilder us. If the mind of man produces designs previously existing in microscopic nature, of which he had no knowledge, it is only reasonable to conclude that his efforts, however feeble, bear in a measure the impression or reflection of that Mind which ‘ hath made all things beautiful in its season’”. Kerr, R. (1895). Hidden beauties of nature, London.
