Counting Chambers from Hausser
These chambers are the finest quality, optically ground, and polished milled glass chambers available. The chamber is diamond etched and has a double improved Neubauer Ruling, which has a worldwide reputation in hospitals and laboratories for unmatched reliability, meeting the most demanding of standards. The standard Hausser blood counting chambers are one piece construction (measuring 75 mm x 32 mm x 4.5 mm) ensuring long term durability and absolute accuracy in measurement and count.
We offer both the standard (incline) and the new "V-Load" counting hambers for different charging methods. The tolerances are (2% of the volume). Cell Depth: 0.100 mm (±2%); Volume: 0.1 Microliter Ruling; Pattern: Improved Neubauer, 1/400 Square mm. Rulings cover 9 square millimeters. Boundary lines of the Neubauer rulings are the center lines of the groups of three. (These are indicated in the illustration). The central square millimeter is ruled into 25 groups of 16 small squares, each group separated by triple lines, the middle one of which is the boundary. The ruled surface is 0.10 mm below the cover glass, so that the volume over each of 16.
Made to Last
In addition to the standard ruling patterns which are etched permanently onto the polished surface, we offer the popular "Bright-Line" counting chamber. This bright-line counting chamber allows the ruling to appear brightly illuminated providing sharp contrast to the bright lines and cells, helping the user with accurate counts and less eyestrain. The triple lines show clearly which cells lie within the counting area and eliminate guesswork.We guarantee that all marks are permanent, and can not be removed even after repeated washings.
Other Chambers and Accessories
In addition to the blood counting chambers, we also offer a variety of other counting chambers and accessories which compliment our discipline.
- The Phase Hemacytometer: used for phase microscopy; it is a one piece brightlined hemacytometer with a reduced thickness.
- The Petroff Hausser Counting Chamber: used for bacteria counting.
- The Sperm Counting Chambers: used primarily in fertility testing; it is offered in a series of depths (10, 20, 40 microns).
- The Howard Mold Counter and the Sedgewick Rafter Counting Chamber are also available as well as a series of hemacytometer and counting chamber cover glasses.
Double Neubauer Ruled Metallized Counting Chamber
An "H" shape moat which forms 2 counting areas are metal plated and double Neubauer ruled providing sharp bright line contrast for consistent cell counts. A "V" cut on each area is used to control the possibility of overflow. Triple dividing lines clearly show cells within the counting area. The ruled surface is 0.1 mm below the cover glass; liquid capacity is 0.1 mm3/mm2 and 0.00025 mm3/grid square.
Ordering: The complete set includes one counting chamber, two 0.5 mm cover glasses, one red cell pipette, one white blood cell pipette, tubing, mouthpieces and carrying case.
