Quartz microscope slides made by our company are based on optical grade high-purity synthetic amorphous silicon dioxide. Unlike conventional quartz slides made of natural fused quartz glass, our quartz object carriers offer a material quality typically used for sophisticated optics. They feature a significantly higher UV transmission for lower UV-wavelengths. The excellent purity enables microscope applications in the DUV (deep ultraviolet) and keeps absorption losses in the UV-range small. All quartz microscope slide products we produce are double side optically polished. They still offer more than 80% light transmission at the very deep UV-wavelength of 185 nm, where for example, ordinary natural fused quartz can typically only transmit less than 50%.

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

Our company supplies all common sizes of quartz microscope slides and coverslips used in science, as listed on this website's dimension table. However, due to in-house production, we are not limited to the few quartz items and dimensions shown in this list. Nearly any shape and size are possible, no matter whether you need round quartz discs, coverslips, quartz plates, or any other quartz glass product. The delivery time for quartz slide products with custom dimensions is just as short as for the standard sizes, so a shopping cart for a limited number of sizes does not make sense. Our 48 h Express Service capabilities are available for any quartz glass thickness listed in the thickness table if you search for the speedy delivery of custom-sized quartz microscope slide items. This unique option offers the manufacturing and shipping of custom-sized quartz slides within two working days, provided there are no additional complex manufacturing steps required. So 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 dimensions (not bold), please take into account that these sizes might significantly lower the piece price compared to 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 standard dimension. Also, round quartz plates, other shapes, and quartz coverslips are available. Please send us your inquiry.
