Quartz microscope slideMost quartz microscope slides we make base on optical grade high-purity synthetic amorphous silicon dioxide. Unlike conventional quartz slides of natural fused quartz glass, our quartz object carriers offer a material quality typically used for sophisticated optics. They feature a significantly higher transmission for lower UV-wavelengths than fused quartz glass products can provide. The excellent purity allows scientific applications in the deep ultraviolet (DUV) and reduces absorption losses in this wavelength range to a minimum. All of the quartz microscope slides we fabricate from synthetic quartz are double side optically polished. They provide more than 80% light transmission at a very deep UV-wavelength of 185 nm, where ordinary fused quartz microscope slides typically transmit less than about 50%.

Our quartz glass slides feature an excellent flatness and surface quality on a level known from optics. Furthermore, they provide the outstanding purity and chemical resistance of high-grade amorphous quartz and enable contamination-free sample storage solutions. No substances or chemicals dissolve from the quartz object carriers or cover glasses into the test sample. Such features are a crucial requirement for special microscopy applications in medical cell research, epidemiology, virology, bioscience, analytics, biotechnology, and lab sample storage solutions.

Our company supplies all standard sizes of quartz microscope slides and coverslips used in science, as listed on this website's dimension table. However, we are not limited to these few quartz items in this list due to in-house production. Nearly any shape and size are possible. Whether you need round quartz discs, coverslips, square quartz cover plates, or other kinds of quartz components, our company supplies a solution.

The delivery time for quartz microscope slides with custom dimensions is just as short as it is for the listed sizes, so a shopping cart for a limited number of items does not make sense. If you search for the speedy delivery of custom-sized quartz microscope slides, our 48 h Express Service is possible for any thickness listed in the thickness table. This unique option offers the manufacturing and shipping of custom-sized quartz microscope slides within two working days after receipt of your order, provided there are no other complex manufacturing steps required. When you order using our 48 h Express Services, you have your tailored quartz microscope slide on your lab table very quickly, so you can continue your project or daily business without delay.

Custom thicknesses on request.
The bold numbers represent the most common standards of microscope slides and coverslips used in the science lab. However, if you can use any alternative smaller slide dimensions (not bold), please take into account that these sizes might significantly lower the piece price compared to the standardized quartz slide sizes. For example, the price of a quartz microscope slide at 23mm x 66mm x 1mm is considerably lower than that of a 25mm x 75mm x 1mm dimension. Also, round quartz plates, other shapes, and quartz coverslips are possible. Please send us your inquiry.
