Quartz microscope slides made by our company are based on optical grade high-purity synthetic amorphous silicon dioxide. Unlike common quartz slides made of natural fused quartz, our slides offer optical quality and have a significantly higher UV transmission even for lower UV-wavelengths. All quartz slide products we produce offer more than 80% of light transmission already at 185 nm. This feature enables deep ultraviolet (DUV) microscopy applications and keeps absorption losses for UV wavelengths very low. Each quartz microscope slide we make 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 the 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 crucial for microscope applications in medical cell research, science, analytics, and for sample storage solutions in the lab.

Our company supplies all the 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 of course are not limited to these 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 times for products with custom dimensions are just as short as for the standard sizes. So a shopping cart for a few standard sizes does not make sense for us.

Even our 48 h Express Service is available in most cases and for many microscope slide items at any thickness listed below. This special 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, and you can continue your project or daily business without delay.

The bold numbers represent 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 sites might result in a significantly lower price than the standard sizes. For example, the piece price of a quartz microscope slide at 23 mm x 66 mm x 1 mm is significantly lower than the one of a 25mm x 75mm x 1mm standard dimension. Also round quartz plates, other shapes, and coverslips are available. Please feel free to send us your request.
