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 object carriers are mainly made of naturally occurring quartz, the so-called "natural fused quartz". Such materials usually do not offer such a very high UV-permeability at wavelengths below 250 nm as optical quartz glasses. 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 (Fused Silica) for the production of our quartz microscope slides. This makes this great deep-ultraviolet transmission (DUV) possible and keeps the absorption losses for UV wavelengths low. All quartz slides and cover glass products we make are double-side optically clear polished and offer an excellent flatness and surface quality. The excellent purity and very good chemical resistance of the amorphous quartz glass 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 test sample. Those features make demanding microscopy applications in medical cell research, science, and in the lab possible.

Our company supplies all the standards sizes of fused silica plates and coverslips used in scientific applications as listed in the table of this website. You can order these at any time. If you are in search of customized quartz microscope slide products or if you need round quartz covers, coverslips, or quartz glass 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 custom sized quartz microscope slides that will be shipping 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 and cover glass sizes. However, if you can use any one of the alternative smaller items (not bold) this might be significantly more economical than the standard slide dimensions. 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.

Thicknesses you can order at short lead times

  • 48h-Express Service 0,3 mm, 0,5 mm, 1 mm, 2 mm and 3 mm
  • Express shipping available

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