  • Significantly higher material quality than conventional slides based on natural quartz
  • Excellent surface quality and flatness
  • Double-side optically polished
  • Low micro-roughness (smooth surfaces)
  • Exceptional material purity
  • Low light absorption
  • Highly resistant against chemicals
  • Temperature resistant up to 1000 °C

Typical Applications

  • Object carriers for advanced microscopy
  • Microscope slides for medical applications and analytics
  • Chemically resistant microscope slides
  • UV and DUV microscopy applications
  • Low-loss and low-absorption coverslips
  • High-temperature microscope stages
  • Sample storage solutions

Our company manufactures and supplies quartz microscope slides from high-purity synthetic amorphous silicon dioxide (UV-quality quartz) for science and research. Ordinary quartz slides are usually made of naturally occurring quartz, the so-called fused quartz. These lower grades of materials cannot offer this very high UV transparency at wavelengths below 250 nm and the excellent optical quality of the synthetic quartz glass (Fused Silica) we use for our microscope slide products. Each quartz microscope slide we produce offers more than 80% light transmission already at a UV-wavelength of 185 nm. This makes deep-ultraviolet applications (DUV) possible and keeps absorption losses for UV wavelengths very low. Each quartz microscope slide and cover slip we make is double side optically polished and offers an excellent flatness and surface quality. The outstanding purity and chemical resistance of the amorphous quartz we use enable sample storage without contamination since no substances or chemicals dissolve from the object carrier into the test sample or the specimen. Those features make demanding microscopy applications in medical cell research, science, analytics, and sample storage solutions in the lab possible.

Our company supplies all the standards sizes of fused-silica microscope slides and quartz coverslips used in science as listed in the table of this website. You can order these at any time. If you are in search of customized sizes or shapes or if you need round quartz discs, coverslips, quartz plates, or any other quartz-based product, you are free to specify a customized dimension, because we manufacture all of these quartz components in-house. We can also produce those custom-sized quartz microscope slides within short lead time. Even our new 48 h Express Service is available in many cases and for many items. This option offers the manufacturing and shipping of custom sized quartz slides within two working days, provided there are no complicated additional manufacturing steps required. So when you order using our 48h Express Services, you have your tailored quartz microscope slide on your lab table very quickly, and you can continue your project or daily business without delay.

The bold numbers represent the most common scientific standards of quartz microscope slides and coverslips in science. However, if you can use any one of the alternative smaller dimensions (not bold), please take into account that this might be significantly more economical than the standard sizes. For example, the piece price of a dimension of 23 mm x 66 mm x 1 mm is significantly lower than the piece price of a 25mm x 75mm x 1mm standard dimension. Of course, also round quartz plates, other microscope slide shapes, and coverslips are available. Please feel free to send us your request.

Quartz Slide thicknesses available with short lead time
