Precise and efficient, [ HUAPINTONG ] plankton counting frame, your good helper for water quality monitoring
0.1ml Suitable for phytoplankton, microflagellates; small planktonic algae, protozoan counting
1ml Suitable small planktonic animals, plankton counting; rotifers, crustaceans, small planktonic organisms, diatoms, ciliates.
The plankton counting frame is a tool used to count and classify plankton under a microscope. Here are the steps to use it
1. Prepare samples
**Concentrate samples: Let the collected samples stand or centrifuge at low speed to precipitate plank.
**Fix samples: Use formaldehyde or Lugol's solution to fix samples as needed to prevent biological degradation.
- **Select counting frame: Choose an appropriate counting based on the size of plankton, such as the Sedgwick-Rafter counting frame and the Palmer-Maloney counting frame.
Ensure the counting chamber is clean Use a pipette to inject the concentrated sample into the counting frame and place the counting frame on the microscope stage.
- **Adjust the microscope: Use the low-power to find plankton and then switch to the high-power objective for detailed observation.
- **Count and classify: Move the counting frame in a certain order and record the and species of plankton in each field of view.
- **Calculate density: Calculate the density of plankton per unit volume based on the volume of the counting frame the concentration factor of the sample.
Precautions
1. Avoid air bubbles: Prevent air bubbles from interfering with counting when injecting samples.
1. Uniform distribution: that the sample is evenly distributed to avoid local clustering.
3. It is recommended to count multiple times and take the average value.
By following the above steps, plank can be accurately counted and classified
Practical design: Includes a counting grid area and a measuring chamber for systematic sampling analysis and standardized monitoring. Easy to operate: The designies with engineering principles, easy to clean and store, and improves experimental efficiency.
2. Durable material: Corrosion-resistant, wear-resistant, suitable for long use, ensuring the stability of experimental data. High-precision scale, made of high-quality optical glass, with clear scales, ensuring accurate division of the counting area and errors. The surface area of the 0.1ml counting pool is 20*20mm, divided into 100 small squares; the area of the 1ml counting pool is 20*50mm, divided into 40 small squares and 1000 small squares, with lines and reusable.
Maintenance of the plankton counting chamber: 1 Do not wipe with hard objects such as coarse cloth or brushes, as this may damage the counting area the chamber. Rinse with clean water after use. 2 Use a lens cleaning cloth to wipe the surface moisture dry, and store it in a storage box. not soak it directly in organic solvents.
