1389 13. Life Sciences Histology/Accessories and reagents GENERAL CATALOGUE EDITION 20 E & OE. Histofluid mounting medium Histofluid is a water-clear adhesive of acrylic resins dissolved in xylene. It hardens fast and due to its optical properties suits perfectly well for embedding microscopic preparations. Shortly after having covered a preparation it can already be examined and filed. Histofluid may also be used to firmly lock and seal bottle caps. - long storing or temperature changes do not cause fissures or deformations in Histofluid layers - does not turn yellowish when being exposed to UV-radiation - does not fluoresce - does not form bubbles - even sensitive colorations are preserved due to its acid number = 0 - refractive index of 1.5 (nD 20 °C) is adjusted to the microscope slide and cover glass - water-repellent and dissolves in, for example, xylene, acetone, chloroform, dioxan and toluol - can be stored in sealed bottles for an unlimited period - filled into special bottles designed for hazardous materials and bearing the UN code Due to its solvent contents Histofluid is flammable and, therefore, considered as hazardous. So it has to be specially packed and shipped according to the international transport regulations. Before ordering please carefully check your country's import regulations and ensure a smooth transport according to the IMO (International Maritime Organization). Any cost that might arise additionally for documents, reloading, returns etc. will be at your expense. 1 Marienfeld Description Capacity PK Cat. No. ml Histofluid mounting medium 500 1 9.160 899 1 Histological staining solutions Stains are delivered in 1000 ml bottles. Each bottle is sufficient for 1500 up to 2500 specimens. They can be used for clinical diagnostics. Harris' hematoxylin solution (Papanicolaou's solution 1a): The cytological staining technique developed by Papanicolaou is still the standard method in cancer and hormone cycle diagnosis. By using the classical Harris' hematoxylin solution (Papanicolaou's solution 1a), excellent nuclear staining can be achieved in 3 to 5 minutes. Nuclei are stained blue, dark violet to black. Densitiy (20 °C): 1.04 g/cm³. pH value (20 °C): 2.3 to 2.8. C.I. 75290: 5.3 g/l. Al 2 (SO 4 ) 3 x 18 H 2 O: 67 g/l Mayer's hemalum solution: This solution does not need to be filtrated prior use and the dye is oxidized in a controlled manner, which renders the results robust and allows a brilliant differentiation of the stained structures. Nuclei are intensive blue, cytoplasm is grey-blue. Density (20 °C): 1.05 g/cm³. pH value (20 °C): 1.8 to 2.2. C.I. 75290: 4.4 g/l. Al 2 (SO 4 ) 3 x 18 H 2 O: 28 g/l. C 6 H 8 O 7 x H 2 O: 0.5 g/l 0.2 % EOSIN Y solution alcoholic: A ready-to-use solution that can be used for routine staining in the hematoxylin-eosin staining process (H&E) of sample material of human origin. Due to the hematoxylin solution, the nuclei will appear blue to dark violet in color and the Eosin Y solution will stain the cytoplasma and intercellular substances red-orange. 2 ORSAtec GmbH Type PK Cat.
