Product Description

Marienfeld 0350000 0.4mm Cover Glass for Neubauer Haemocytometer Counting Chamber

Model 0350000 is Germany original Marienfeld Superior dedicated counting chamber cover glass, tailor-made to match all series Marienfeld Neubauer improved haemocytometers, the essential matching consumable for manual cell concentration counting.

Different from standard No.1 thin microscopy coverslip, this product adopts exclusive 0.4mm thick special optical glass sheet. Ultra high flat surface tightly attaches to the two bearing platforms of counting chamber, automatically forming standardized 0.1mm capillary height between grid and cover glass, which is the core premise to accurately convert cell suspension concentration. If ordinary thin cover glass is used, uneven warping will change capillary volume and cause large counting deviation.

All four edges are precisely ground and polished to eliminate sharp edges, preventing scratches on the fragile metal grid of counting chamber; smooth edge surface also supports uniform blood smear preparation. Every piece undergoes multi-stage factory pre-cleaning, free of surfactant residue, ready for blood cell, yeast and mammalian cell counting directly out of package.

The product holds EU IVDR CE certification, all packaging printed traceable batch number to meet clinical laboratory and pharmaceutical R&D compliance audit demands. Single piece individually packed in anti-dust polybag, 10 pieces per mini plastic box, 10 mini boxes (total 100pcs) per outer carton. Widely applied in clinical hematology testing, biotech cell culture labs, microbiology fermentation research, university life science teaching and cosmetic raw material microbial inspection.
