Ossa Fixona®

Ossa Fixona® is a fast, conservative, simultaneous fixation and decalcifying solution for preparing bone for histological examination. The time required for decalcification depends on sample thickness.

Subsequent neutralisation is not required and the decalcified tissue can be further treated using standard techniques. In contrast to other decalcification methods, Ossa Fixona® enhances haematoxylin staining. You will benefit from samples with above average preservation and staining of haematopoietic cells.

Testsimplets® are ready-to-use slides coated with standardised stains for cost-effective differential-diagnostic microscopy. They are easy and clean to use with no staining procedure, and are ideal for blood smears for differential blood counts. Other areas of use include carcinoma cytology, urinary cytology, cerebrospinal fluid cytology, nasal cytology and spermatozoa staining. Testsimplets® are particularly useful for examining single samples and small series of samples. The use of chemically pure stains at a constant ratio applied uniformly to the slide guarantees even staining of consistently high quality.
