Description
Comparison tubes for Sahli haemometer are precision laboratory tubes manufactured from soda-lime glass with a round bottom and rim. They incorporate a double colour scale in yellow and red for classical haemoglobin determination according to the Sahli method. The scales are matched to the colour glass rods of currently produced haemometers from manufacturer Marienfeld, ensuring reliable visual comparison; the tubes are therefore not compatible with older models or instruments from other manufacturers. Each box contains 10 pieces for convenient laboratory handling. The product is not registered for in-vitro diagnostic applications within the EU and is intended for general laboratory comparison work. Durable soda-lime glass construction supports routine haematology workflows, while the dual yellow/red scale enables clear matching against reference standards. Bulk packaging of 100 boxes of 10 pieces is available for higher-volume requirements. These comparison tubes provide a practical accessory for laboratories that continue to employ traditional Sahli-based haemoglobin measurement protocols.
This article is part of Test tubes, in Tubes & vials.

Questions about Comparator tubes for haemometers acc. to Sahli
What is this article?
Comparator tubes for haemometers acc. to Sahli is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Test tubes, inside Tubes & vials, in Labware.
A test tube is the open cylindrical vessel for a small liquid, in borosilicate glass or in plastic. Rimmed and rimless mouths differ. The size is diameter by length. It is not graduated for a result, and a glass tube that will be centrifuged has a force limit.
A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
