What is Sedgewick Rafter counting chamber?
The premier counting cell designed specifically for the quantitative measurement of the exact number of particles in a precise volume of a fluid.
What is Sedgwick Rafter?
The Sedgwick-Rafter Counting Cell is a standard counting cell designed for counting larger plankton on a compound microscope (up to 200x) or on an inverted microscope (higher magnifications possible). The cell volume is exactly 1.0 mL and consists of a ceramic rectangular frame mounted on a 1″ x 3″ glass slide.
What are the other types of cell counting chambers?

- EMS Sedgewick-Rafter Counting Cells.
- Counting Chambers from Hausser.
- Double Neubauer Ruled Metallized Counting Chamber.
- Etched – Transparent Field with Opaque Pattern Levy Double Neubauer.
- Fuchs-Rosenthal Counting Chamber.
- Petroff-Hausser Counting Chamber.

How is Haemocytometer used to count cells?
To count cells using a hemocytometer, add 15-20μl of cell suspension between the hemocytometer and cover glass using a P-20 Pipetman. Count the number of cells in all four outer squares divide by four (the mean number of cells/square). The number of cells per square x 104 = the number of cells/ml of suspension.
How do you calculate phytoplankton?
In the flow cytometry counting method, a flow cytometer instrument is used to count phytoplankton cells that pass through its measurement cell to determine cells per volume concentration.
How many types of counting chambers are there?
There are two counting chambers per slide for replicates. The counting grid pattern is the Improved Neubauer, as in a common Hemacytometer.
How do you count the counting chambers of RBC?
Principle: The blood specimen is diluted 1: 200 with the RBC diluting fluid cell are counted under high power (10 X objective) by using a counting chamber. The number of cells in undiluted blood calculated and reported as the number of red cells per cum (µl) of whole blood.
How much does a hemocytometer cost?
Hemocytometer for Cell Counting
| Description/Item No. | Qty. | Your Cost/Qty |
|---|---|---|
| Standard Hemocytometer 3048-12 | Each | $132.75/EA |
| Bright Line Hemocytometer 3048-11 | Each | $194.01/EA |
How much does it cost to load a hemocytometer?
To count cells using a hemocytometer, add 15-20μl of cell suspension between the hemocytometer and cover glass using a P-20 Pipetman. The goal is to have roughly 100-200 cells/square.
