  • Information about our microscope slides
Microscope slides for in vitro diagnostic applications are manufactured acc. to ISO 8037/1 standard and designed for single use by professionals. The main purpose is the microscopic investigation of tissue sections and cells from suspensions, preparation of specimens and their archiving.
Marienfeld Superior microscope slides stand out by their exceptional wettability and cleanliness. They are manufactured to exact size and are thus well suitable for application in automatic machinery.


Our microscope slides are made of soda lime glass of 3. hydrolytic class with thickness of approx. 1 mm. This glass fulfills all relevant optical properties for light microscopy. Its composition and physical properties (technical datasheet) can be downloaded from our website.


Our slides are cleaned thoroughly by multi-stage processes without using any surfactants. Thus we accomplish ready for use, pre-cleaned, well wettable slides‘ surfaces. They preserve adhering cells and are well suited for smears of cell suspensions.

Slides’ edges:

All grinding and polishing processes are always carried out water-cooled. The supreme quality of our edges is unmatched.
For different applications we offer different types of edges:
  • cut edges are suitable for routine applications, when risks of infections do not exist and the economical aspect is of major importance
  • finely ground edges with 90º shape. We manufacture with water-cooled grinding processes, which result in remarkably smooth and burr-free edges. When handling infectious materials we strongly recommend using this type of slides for increased safety.
  • finely ground edges with 90º shape and 4 ground corners chamfered at 45°. These slides improve the safety and reduce the risks of cuts. They may facilitate the smooth conveyance when used on some automatic machinery.

Marking areas:

Our silky frosted marking area is suitable for a fine and contrasty writing with pencil. It has a width of approx. 20 mm by standard; however, other widths can be produced on request. Our twin-frosted slides (at one end, on both sides) can be used from either side without the necessity of searching the surface that bears the frosted area.
Our printed marking area in white colour or light pastel shades can take notes printed by most types of printers and written with permanent markers (e.g. laboratory marker Cat. No. 6130603). The thin coating of the marking area prevents the slides from sticking together and enables using them on automated systems.

Quality control:

All our microscope slides are subject to strict quality controls during the production processes and on the finished product, too.

Shelf life:

Soda lime glass is subject to an aging process which affects the quality of the slides. It is recommended to avoid storing the slides for too long and to use the oldest stocks at first. Your early disposition of slides helps us to optimize our production planning and to supply the slides in time. Use up the microscope slides until the recommended best-before date. Use the oldest stock at first (first in – first out).


  • store microscope slides always in a dry place
  • open the carton only when slides reached the room temperature
  • make sure that temperature remains constant. When cooling down condensation may occur and penetrate between the slides letting them stick together.
  • do not store slides close to solvents as this might turn their surfaces hydrophobic

Our packing material is made from high quality primary material without recycled paper. As a result, our boxes are resistant to abrasion and do not affect the quality of the microscope slides. After use, they can be disposed as quality recycling paper. The boxes have an enlarged finger hole and a fold-back rear which facilitates the removal of the individual slides.

We supply microscope slides in small sales units of 2500 pieces (50 boxes of 50 pieces). This carton is reclosable, easy to handle and stack. Its dimensions are 283 x 146 x 160 mm and the weight is approx. 12 kg.
