Venditore: Top-Rated Seller diatomshop (1.001) 100%, Luogo in cui si trova l'oggetto: CR, Spedizione verso: Worldwide, Numero oggetto: 292294882213 Diatom Shop's logo video: http://www.diatomshop.com/videos/Diatom-Shop-by-Diatom-Lab-HD.mp4 Diatom Lab's logo video: http://www.diatomshop.com/videos/Diatom-Lab--HD.mp4 This eBay auction is for a fine microscope slide with one selected and micro-manipulated marine fossil diatom,Biddulphia pulchella S.F.Gray 1821, perfectly cleaned in Diatom Lab (Diatom Shop)'s laboratory, mounted on coverslip in Diatom³ (Diatom Cubed), high refractive index mountant for diatom preparations with excellent chemical stability! This species has a deep pervalval axis. This beautiful specimen has been collected in Saint Laurent La Vernède (France). This microscope slide has no bubbles inside and no impurities on or near the preparation: it is a very clean jewel for the microscopist! You can see the live view window of Diatom Lab's microscope camera (no focus stacking, just one focal plane!) obtained with a 5x objective in darkfield: if you increase magnification you can see different or more details of course. Diatom Shop makes COMBINED SHIPPING: visit all the eBay products in the eBay store http://www.ebay.com/usr/diatomshop IF YOU WIN / BUY MORE THAN ONE PRODUCT IN THE SAME DAY PLEASE WAIT FOR THE DIATOM SHOP E-MAIL WITH THE COMBINED SHIPPING COSTS, SO YOU CAN SAVE A LOT ON SHIPPING CHARGES: shipping up to 5 slides worldwide by registered international parcel with tracking number costs 10 euros and for more than 5 slides you always pay 16 euros for the worldwide shipping! The eBay starting price is ridiculous: it doesn't mean that the product is of poor quality, however in this way each of you can potentially win this product! Diatom Shop offers TOP QUALITY PRODUCTS and TOP QUALITY SERVICE, to sum up: 1) Microscope slides are made to LAST IN TIME and are produced using the PROFESSIONAL , MODERN, UNPUBLISHED, LATEST & UNIQUE Diatom Lab's TECHNIQUES AND FORMULAS! 2) Diatom Shop's Diatoms and Radiolarians can be observed and admired EVEN WITH A MODEST MICROSCOPE (contrast enhancement techniques such as phase contrast, darkfield illumination and differential interference contrast are not necessary!) thanks to Diatom Lab's high refractive index mountants used to mount them! 3) Diatom Lab uses several HIGH REFRACTIVE INDEX MOUNTANTS, such as Diatom³ (DIATOM CUBED) that has a refractive index greater than 1.7. All mountants are MICROFILTERED and have an EXCELLENT CHEMICAL STABILITY! 4) Diatom Lab's self-produced mountants and fixatives are really INVISIBLE even in Phase Contrast, Darkfield illumination and Differential Interference Contrast (DIC)! 5) In order to give you the BEST CONDITIONS FOR RESOLUTION AND CONTRAST, Diatom frustules are internally mounted ON THE LOWER SURFACE OF COVER GLASS (and not classically on microscope slide), although this procedure requires special manufacturing precautions! Furthermore, mounting on the internal surface of cover glass permits to easily use oil immersion objectives too (even those with very short free working distance: 63x/1,4 or 100x/1,4) as there is no space between diatoms and cover glass! 6) Diatom Lab's special techniques and mountants ensure that diatoms and radiolarians WILL NEVER CHANGE THEIR ORIGINAL POSITION (for example, during shipping or storage): in a few words you will never see "floating" diatoms and radiolarians! 7) The customized cover glasses (coverslips) with HIGH OPTICAL QUALITY have been manufactured in Germany specifically for Diatom Lab. They have the following characteristics: highly transparent and achromatic (free of any color distortion); high optical omogeneity (pratically free of inclusions, bubbles, streaks, etc.); high spectral transmission; good planarity; very good chemical stability; refraction index adjusted for microscopes! 8) Diatom Shop's microscope slides are prepared taking into account the coverslip thickness suitable for each preparation! 9) Diatom Shop's ringing cements are resistant to the most common immersion oils used in optical microscopy! 10) Diatom Shop offers PERFECTLY CLEANED Diatoms, Radiolarians and other microscopic objects that are micro-manipulated paying attention to their perfect positioning. All the recent and fossil Diatoms and Radiolarians are cleaned the internal laboratory (using long, professional and dangerous techniques that require personal protective equipment)! 11) Diatom Shop always offers many RARE and UNUSUAL species! 12) Diatom Lab (Diatom Shop) 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! 13) 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! 14) Payments are possible using PayPal (no PayPal account needed, just a credit card!) or bank transfer! 15) Please read the 100% POSTIVE eBay FEEDBACKS!
