Quartz microscope slides made by us are based on optical grade high-purity synthetic amorphous silicon dioxide. Unlike conventional quartz slides made of natural fused quartz glass, the quartz object carriers made by our company offer optics quality and a significantly higher UV transmission for lower UV-wavelengths. All quartz microscope slide products we produce offer more than 80% of light transmission already at 185 nm. The material quality enables deep ultraviolet (DUV) microscope applications and keeps absorption losses for UV wavelengths very low. Each quartz microscope slide we manufacture is double side optically polished and offers an excellent flatness and surface quality on a level known from optics.

The outstanding purity and chemical resistance of high-quality amorphous quartz enable contamination-free sample storage solutions since no substances or chemicals can dissolve from the pure quartz object carrier into the test sample. Such features are a crucial requirement for special microscopy applications in medical cell research, science, analytics, and for sample storage solutions in the lab.

Our company supplies all standards sizes of quartz microscope slides and coverslips used in science, as listed in the table of this website. Due to in-house production, we are not limited to these quartz items. Almost any shape and size is possible, no matter whether you need round quartz discs, coverslips, quartz plates, or any other quartz based product. The lead time for quartz slide products with custom dimensions is just as short as for the standard sizes, so a shopping cart for limited size options does not make sense.

If you search for the speedy delivery of custom-sized quartz microscope slide items, our 48 h Express Service capabilities are available for any quartz glass thickness, as listed below. 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 to be able to continue your project or daily business without delay.

The bold numbers represent the most common standards of microscope slides and coverslips used in the science lab. However, if you can use any one of the alternative smaller dimensions (not bold), please take into account that these sizes might result in a significantly lower piece price than for the standard quartz slide sizes. For example, the price of a quartz microscope slide at 23mm x 66mm x 1mm is significantly lower than the one 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.
