Our company manufactures and supplies quartz microscope slides for science and research from high-purity, synthetic amorphous silicon dioxide (UV-quality quartz glass). Ordinary quartz microscope slides are mainly made of naturally occurring quartz, the so-called "natural fused quartz". Such quartz microscope slides usually do not offer such high UV permeability at wavelengths below approx. 240 nm. Each quartz microscope slide we manufacture already offers maximum light transmission for significantly shorter UV wavelengths. In order to achieve a transmission of more than 80% at 185 nm already, we exclusively use high quality synthetic quartz glass for the production of our quartz microscope slides, which enables a very high deep ultraviolet transmission (DUV) and keeps the absorption losses for UV wavelengths low. All quartz microscope slides we make are double-side optically clear polished and offer an excellent flatness and surface quality. The extraordinarily high purity and very good chemical resistance of the amorphous quartz glass, which we use for the slides, allows the use and storage of samples without them being defiled, because nearly no substances or chemicals are dissolved from the slide material into the specimen or sample. Those features facilitate demanding microscopy applications in medical cell research, science and in the lab.

Our company supplies all the standards sizes of fused silica plates and coverslips used in scientific microscopy as listed in the table of this website. You can order these slides at any time. If you are in search of customized quartz microscope slide products, or in case you need round quartz discs, coverslips or quartz-based optics, we can help you as well, because we manufacture these components in-house. We can produce most custom-sized quartz slide components within a very short lead time. Even our new 48 h Express Service is available in many cases. This option allows to manufacture and ship custom sized quartz microscope slides within two working days, provided there are no complex additional manufacturing steps required. So, using our 48 h Express Services, you will have your tailored quartz components extremely quick on your lab table, so you can continue your project or daily business without delays.

The bold dimensions are the most common standard quartz microscope slide sizes. However, if you can use any one of the alternative, smaller sizes (not bold), this might be significantly more economical than the standards. For example the piece price of a slide size of 25 mm x 66 mm x 1 mm is lower than the piece price of a 25 mm x 75 mm x 1 mm standard dimension. Of course also round quartz plates and other shapes are available.

Note: Besides the quartz microscope slides and cover slips described in this website, it belongs to our business as well to make glass components for microscopy from any of the many other specialty materials that are part of our large inventory. If you are in search for such kind of specialty microscope slides, please let us know your requirements or send us an e-mail and we will immediately return our quotation.
