Advantages and usage methods of stainless steel water quality sampler
1、 Core advantages
Corrosion resistance and adaptability
Made of 304/316 stainless steel material, it can withstand acidic and alkaline corrosive liquids such as seawater and industrial wastewater, and is suitable for complex environments such as marine, chemical, and environmental protection.
Some models (such as HB68/HBC-1B) are equipped with polytetrafluoroethylene (PTFE) outlet pipes to ensure pollution-free sampling process, especially suitable for analysis of trace organic matter, oils, microorganisms and other indicators.
Accurate sampling and depth control
By designing structures such as movable bottom plates and double semi-circular covers, precise sampling at any depth can be achieved (such as fixed depth sampling within 50 meters).
During sampling, the water body passes through the bottle to avoid mixing water samples from different depths and ensure sample representativeness.
High temperature and extreme environmental support
PTFE seals support trace organic sample collection up to 230 ℃, suitable for high-temperature industrial environments or special experimental needs.
The float ball automatically controls the opening/closing of the sampling bottle mouth, with flexible operation, suitable for high flow rate water environments.
Anti pollution and anti volatilization design
After sampling, the glass bottle can be directly removed without transferring the sample, avoiding secondary pollution and loss of volatile components.
The silicone pad on the inside of the card cover is designed to seal the mouth of the sampling bottle, ensuring the sealing of underwater sampling.
Portability and ease of operation
Equipped with a 30 meter dedicated cable or portable bag, it supports use in outdoor environments without power supply.
The rotating bracket can be manually flipped 90 degrees for easy sample retrieval and improved operational efficiency.
2、 Usage method
Pre-operation preparation
Cleaning and inspection: Clean the sampler to avoid cross contamination; Check the sealing performance to ensure no leakage.
Assembly and fixation: Place the glass bottle into the sampling cage and secure it with screws; Connect the float rope to the sampler rope and straighten it out for future use.
Location selection: Sampling points should avoid weeds and large particle impurities, and choose areas with uniform flow velocity and no obvious pollution.
Sampling process
Sinking and injection:
Hold the chain and sink the sampler into the water at a speed of ≤ 1 meter/second.
After reaching the target depth, lift the stopper zipper or pull the sampler rope to open the bottle stopper and allow the water sample to enter the glass bottle.
Let it stand for a moment, and after no bubbles emerge, lift it out of the water surface.
Depth control:
Use ropes to mark the sinking depth and ensure accurate sampling levels.
The fixed depth sampler automatically closes the valve through a floating bottom plate to avoid mixing water samples at different depths.
Post sampling processing
Water sample transfer: After raising the water surface, avoid touching the bottom injection port to prevent sample leakage.
Sealing and preservation:
Insert the water outlet rubber tube into the container mouth, release the water stop clamp, and inject the water sample into the sample container.
Add preservatives (such as acidifiers) according to the sample requirements, seal and refrigerate for transportation (0-5 ℃).
Recording and identification: Detailed recording of sampling time, location, depth, weather and other information, indicating sample number and sampling personnel.
Maintenance and Care
Clean the sampler promptly after each use to avoid residual water samples affecting the next use.
Regularly inspect components such as seals, card covers, and rotating brackets to ensure long-term stable operation.
During the warranty period (usually 1 year), you can enjoy free maintenance, parts replacement, and 24-hour response service.
3、 Application scenarios
Environmental monitoring: Analysis of water quality in oceans, rivers, and lakes, supporting detection of indicators such as microorganisms, oils, and trace organic matter.
Industrial field: Sampling of chemical wastewater and high-temperature industrial water bodies, resistant to acid, alkali, and corrosive liquids.
Research experiment: Layered sampling of deep water bodies and collection of extreme environmental water samples to meet high-precision experimental requirements.
