USE AND PRECAUTIONS
The hemocyte-counting plate is a special thick type of slide on which there is Four slots formthree platforms. The platform in the middle is wider, and in the middle is another one The shorttransverse groove is divided into two halves, each of which is carved with a small square meshEach grid is divided into nine large squares, and the central square is used for counting.This iscalled the counting area. There are two scales in the counting area: one is the count divided into 16The middle square (the largesquareis separated bythree lines), and each middlesquareis dividedinto two 25 small squares; The other is a count differentiated into 25 middle squares (middleThe squares are separated by double lines), and each square is divided into 16 smaller squaresLattice. But regardless ofthe construction of the counting area, they all have one thingin commonCharacteristics, that is, the counting area is composed of 400 small squares. The side length of thecounting area islmm, then the area ofthe counting area is lmm?, and the area of each small squareis 1/400mm?. The height of the counting area is 0.lmm after covering the cover slip, so The volumeof each counting area was 0.lmm,, and the volume of each small square was denoted 1/400mm.
1. Each blood cell count plate is packaged independently with plastic cartridges and used from the cardTake the product out ofthe shell and check whether the model specification printed on the counter board is correct;
2. Microscopic examination of the counting cell: before adding the sample, the counting cell of the counter plate should beexamined under microscope.lfthere is dirt, it needs to be cleaned and dried before counting.
3. Add the sample: cover the counting chamber ofthe clean and dry blood cell counting board with a special lid Using a coveiglass to absorb diluted samples (e.g., blood,Microbial suspension), drop on the edge ofthe cover slip, and allow the solution topercolate slowly Fill the counting cell once to prevent bubbles and fil the suspension to be tested The amount should notexceed the rectangular edge between the counter top of the counting cell and the cover glass.Excess liquid to be measuredcan be absorbed by filter paper;
4. Count: wait for a moment (about 5min), and all the cells in the test liguid settleAfter counting the bottom ofthe cell, placethe counter board in the center ofthe stage,first at low magnification After finding the location of the counting chamber undelthe microscope, the high power microscope was converted to observe and count And record.
1. Shake the test tube lightly before drawing the sample solution from the test tube for counting A few times, so that it is evenlydistributed;
2. lf the quantity in a small square is too large to count, it needs to be diluted;
3. Counting a sample is calculated from the average of two counting chambers. Each sample could be counted three times andthen averaged;
4. When counting, the focal length should be adjusted from time to time to observe samples at different depths;5. Do not use a blood cell counting board beyond its expiration date.
In an era dominated by high-throughput flow cytometers and automated image analysis systems, the humble cell counting chamber remains an indispensable tool in biological and medical laboratories worldwide. Often referred to as a hemocytometer, this precision-engineered glass slide is far from obsolete. Its continued prevalence is a testament to a unique set of advantages that sophisticated, expensive machinery cannot fully replicate. For researchers, clinicians, and students, the cell counting chamber offers a combination of direct visualization, accessibility, and reliability that secures its vital role in quantitative cell biology.
The most significant advantage of using a cell counting chamber is its provision of direct, visual confirmation. Unlike automated systems that operate as "black boxes," processing samples without user oversight, the hemocytometer allows the scientist to observe the cells directly under a microscope. This enables critical qualitative assessment alongside quantitative data. The researcher can immediately identify cell viability through trypan blue exclusion, detect the presence of clumps or debris that could skew counts, and observe the overall health and morphology of the culture. This hands-on interaction with the sample provides a layer of quality control that is irreplaceable, ensuring that the counted numbers are biologically meaningful.
Furthermore, the cell counting chamber is unparalleled in its accessibility and cost-effectiveness. A high-quality hemocytometer is a one-time investment that requires only a standard laboratory microscope for operation. This places precise cellular quantification within reach of virtually any lab, regardless of budget constraints. There are no expensive service contracts, proprietary reagents, or software licensing fees. This low barrier to entry makes the cell counting chamber a fundamental tool in teaching laboratories, field clinics, and startup research facilities where resources are limited. Its simplicity ensures that vital work can proceed without dependency on complex instrumentation.
