Knittel : Quelles slides/blades and coverslips for the microscopy andthe histology ?

Germany’s benchmark in technical glass for microscopy, Waldemar Knittel designs and manufactures slides and coverslips that make a difference at the bench and in theatre. From StarFrost slides to adhesive versions for delicate tissues, the brand delivers exemplary flatness, cleanliness and dimensional consistency. Widely trusted in histology, cytology and R&D, it keeps your preparations, stains and imaging dependable. With Knittel, every section, every cell and every image rests on a reliable substrate, engineered for laboratory automation and modern quality standards.

The specialist in microscope slides and coverslips — your long-term essential

For several decades, Knittel has focused on a single craft: glass processing for microscopy. Founded in Germany, the company has built its reputation on precise industrial expertise (cutting, polishing, bevelling, cleaning in a controlled environment) and rigorous batch-by-batch quality control. Over time, it has expanded its range with coloured microscope slides for unambiguous identification, followed by surface treatments that ensure reliable tissue adhesion for histology and immunolabelling. By listening to the needs of pathology laboratories, quality control labs and academic centres, Knittel has established an international distribution network while maintaining tightly controlled production, aligned with European standards and traceability requirements.

Expertise and capabilities

The core expertise of Knittel lies in microscope slides and coverslips whose mechanical consistency and surface cleanliness deliver reproducible preparations. StarFrost slides feature a crisp frosted, coloured labelling area for handwriting or barcodes, remaining highly legible after staining. Adhesive slides secure the adhesion of thin sections (FFPE, cryo) through demanding histology, IHC and ISH workflows. Optical-glass coverslips provide transparency, flatness and controlled thickness for artefact-free image capture in light microscopy and fluorescence.

Knittel focuses on dimensional consistency, particulate cleanliness and compatibility with staining instruments and archiving systems. Washing and packaging processes minimise contamination, reduce sample loss and stabilise staining intensities. For pathology, microbiology or R&D labs, that translates into sections that stick, uniform stains, slides that do not warp and coverslips that introduce no optical stress.

Beyond the product, the brand provides clear lot traceability, controlled tolerances and packaging tuned to throughput: protective boxes, varied formats and colour options for instant sorting. A pragmatic approach: reliability, repeatability and ease of use to free up analytical time and cut waste – all key advantages in accredited environments.

Frequently asked questions about the Knittel brand

Are Knittel slides compatible with automated stainers and slide scanners?
Yes. Their flatness, polished edges and surface cleanliness ensure smooth instrument feeding and reproducible image acquisition.

What is the difference between StarFrost slides and adhesive slides?
StarFrost provides a coloured, frosted marking area for sample identification. Adhesive versions add a surface treatment for enhanced tissue adhesion.

What are the main application areas?
Histology, cytology, immunostaining (IHC/ISH), microbiology and R&D work requiring stable, clean substrates.

Do the coverslips have controlled thickness?
Yes. Optical coverslips are supplied in standardised thicknesses to ensure focus and image quality at the microscope.

How does Knittel manage quality and traceability?
Material selection, dimensional and cleanliness checks, lot numbers and careful packaging to guarantee consistency and traceability.
