Bright-Line Dark-Line Counting Chambers Catalog Numbers: 3100, 3110, 3200, 3500, 1490, 1492, 1475, & 1483 Usage: Cell Counts Cell Depth: 0.100mm +- 2% (110mm) Volume: 0.1 Microliter Ruling Pattern: Improved Neubauer, 1400 Square mm Rulings cover 9 square millimeters. Boundary lines of the Neubauer ruling are the center lines of the groups of three. (These are indicated in the illustration below.) 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 0.10mm below the cover glass, so that the volume over each of the 16 small squares is .00025 cubic mm.

Fuchs-Rosenthal Chamber Catalog Number: 3720 Usage: Cell Counts in Cerebro-Spinal Fluid Cell Depth: 0.2mm Volume: 0.2 Microliters Ruling Pattern: Fuchs-Rosenthal (Dark-Line) Diluting fluid for counting cells in Cerebro-Spinal Fluid Crystal or Methyl Violet...................................0.2 gm Glacial Acetic Acid............................................10 cc Distilled Water...................................................90 cc Collect about five CC. of spinal fluid in a sterile test tube containing a trace of Potassium Oxalate to prevent coagulation. The specimen should contain no visible trace of blood. Fill the capillary of a 1:10 pipette to the graduation with the diluting fluid and then draw the spinal fluid to the graduation above the bulb. Shake the pipette and charge the chamber as with blood corpuscle counting technique. Allow several minutes for settling. The chambers are ruled with the Fuchs-Rosenthal pattern. This consists of 16 one square millimeter areas orientated by triple lines, and each such area sub-divided into 16 squares. It is generally recommended to count 16 one square millimeter areas preferably 8 in each chamber.

McMaster Egg Slide Catalog Number: 3875 1) Weigh out 2 grams of feces 2) Pass feces through a sieve into a dish containing 60 ml of ZnSO4 or saturated salt solution. 3) Stirring vigorously (transfer solution to a flask to prevent spillage), take a sample with a pipette or medicine dropper and load one of the chamber of the slide. Repeat and fill other chamber. 4) Wait 30 seconds for the eggs to float to the upper surface of the counting chamber.Two focal planes exist, with the eggs an air bubbles in the upper plane. Focus on air bubbles, then count the total number of eggs under both of the grids. Do not count eggs outside of the grid. 5) Multiply the total number of eggs in the two chambers by 100, this is the eggs per gram(EPG). To clean the counting chamber: After completing the count, remove the cover glass and clean the counting chamber with water or a mild cleaning solution (10% solution of bleach). Dry the counting chamber with a soft cloth or wipe, or rinse with acetone.

The Hausser Nageotte Bright-Line Hemacytometer allows one to manually count low leukocyte concentrations below the capabilities of a standard Hemacytometer. The Nageotte contains two gridded counting areas each containing 40 rectangular areas. Total volume of each grid is 50 mL for a total volume of 100 mL per Nageotte. The Nageotte can accurately measure down to 0.1 cellmL (100 cellml). Cell Depth is 0.5mm .Available with an H-shaped moat(catalog#4000) that separates the two gridded areas or without a moat (catalog#4001). The Nageotte Chamber comes with two reusable cover slips(30mm X 33mm X 0.5mm) and 12 oz (approx. 35 pcs.) of disposable cover slips (30mm X 33mm X 0.15mm).

The chamber is of all glass construction. A shallow glass cell, 17.9mm dia. x 0.4mm deep, is cut from plane glass plate and fused to a 75 x 25mm polished glass slide. Easy charging provided by two channels, 2mm x 5mm. Forms flat bottom chamber of approximately 0.1mL capacity. This instrument is for counting smaller plankters, using 43x dry objectives of approximately 0.65 n.a. and 4 mm e.f. The plane cover glass is 22 x 22mm and 0.16-0.19mm thick.

The Speirs-Levy Eosinophil counting slide is designed primarily for doing direct eosinphil counts in blood, but is readily adaptable for performing cell counts in spinal fluids or other media in which cells are suspended. It is especially useful in clinics and laboratories where large number of blood cell determinations must be performed quickly. The Speirs-Levy slide has the following characteristics which facilitate loading and counting: 1. There are 4 chambers per slide 2. Each chamber consists of ten 1 x 1mm squares which are subdivided into 16 smaller areas. 3. The depth of each chamber is 0.2 mm. 4. The chambers are spaced on the left hand side of the slide for ease of handling and to prevent accidental reversing of the slide. 5. An identification number is engraved on the right hand side of each chamber and will appear on the left hand side when viewed through the microscope. This number helps focusing and may be used to determine the beginning and end of a chamber count. 6. The outer edge of each chamber is inclined 7 degrees to aid in proper charging of the chamber and to act as a reservoir to replace any fluid that might evaporate before the slide is counted.
