The water bath photoelectrochemical cell is a precision equipment that integrates temperature control, optical window, and electrochemical measurement functions. Its storage method needs to be particularly meticulous, followingClean, dry, and damage resistantThe core principles.

The following are detailed saving steps and precautions:

Core principles: Keep clean, keep dry, professional packaging, controllable environment

1、 Key preprocessing before saving

The saved state determines the performance of restoring usage, so preprocessing is crucial.

1. Safe disassembly:

• Turn off all power sources (electrochemical workstation, light source, circulating water bath) and wait for the pool to cool to room temperature.

• Carefully disassemble all components:Working electrode, counter electrode, reference electrode, temperature sensor, intake/exhaust pipe, sealing cover/O-ring.

2. Partition cleaning:

• Pool body and reaction chamber:

• Inorganic salts/electrolytes:Soak in dilute nitric acid (≤ 1 M) or dilute hydrochloric acid and rinse.

• organic compound:Clean with solvents such as ethanol and acetone.

• Immediately rinse:Pour out the waste liquid and use a large amountWarm deionized water/ultrapure waterRepeatedly rinse the inner wall.

• Deep cleaning:Select cleaning agents based on the properties of the residue.

• [Taboo]It is strictly prohibited to use HF, as it can corrode quartz and glass optical windows.

• Optical window (most vulnerable part):

• adoptLens Cleaning MethodWetted with acetone or ethanolDust-free cotton swabsorLens paperGently wipe in one direction. Do not draw circles or use hard objects.

• Finally, rinse with ultrapure water and useear bulb syringeBlow dry and avoid wiping with a cloth.

• Water bath jacket:

• Drain the circulating water inside the jacket.

• If you have used tap water, it is recommended to use it5% citric acid solutionCycle cleaning to remove scale, then thoroughly rinse the inside of the jacket with deionized water.

• Practice:Before long-term storage, inject a small amount of deionized water into the jacket and circulate for a few minutes before emptying to ensure internal cleanliness.

• Seals (O-rings, gaskets):

• After removal, rinse separately with water and ethanol to check for anyAging, deformation or damageReplace it promptly.

3. Rinse and dry:

   rinse:All components must be cleaned with any cleaning agent before useA large amount of ultrapure waterRinse thoroughly to ensure there are no chemical residues.

   dry:

1. useLint free fabricWipe all external surfaces dry.

2. useear bulb syringeorLow pressure, clean nitrogen gasBlow dry the inner wall, interfaces, threads, and optical windows of the tank body.

3. Move the pool bodyinvertIn cleanDust free environmentIn the middle, let itair-drying.Do not use an oven for high-temperature bakingTo avoid generating thermal stress or damaging the seals.

2、 Specific methods for long-term preservation

1. Disassemble and store, do not assemble:

• Do not store the assembled components after assembly!The pool body, electrodes, sensors, sealing rings, etc. should be installedStore them all separately.

• This can prevent the sealing ring from being compressed and deformed for a long time, and avoid different material components (such as glass grinding edges) from being "stuck" and unable to open due to thermal expansion and contraction.

2. Professional packaging:

• Use the dried main body of the tankbubble wraporLaboratory dust-free paperPackage.

• Optical window protection:Cover with specializedPlastic protective coverOr gently cover with dust-free paper to prevent dust and scratches.

• Prioritize returning to the original box:The original packaging box is tailor-made for it and can provide good protection. Fill the gaps with soft material inside the box to ensure that the pool body does not shake.

3. Suitable storage environment:

• Environmental requirements: Dry, clean, dark, and at room temperature.

• Location:Store in a sturdy cabinet or drawer to avoid any risk of collision or compression.

• Avoid chemical pollution: Do not store volatile chemicals such as acids and bases in the same enclosed spaceTo prevent its volatiles from corroding the pool body or optical window.

Summary: Save Process Checklist

1. disassembleAfter cooling, carefully disassemble all components.

2. cleanClean the pool body, optical window, jacket, and sealing components in designated areas.

3. rinseRinse all cleaning agents thoroughly with ultrapure water.

4. dryWipe, blow dry with nitrogen, and invert and air dry naturally.

5. checkCheck the sealing ring and replace it immediately if it is damaged.

6. packagingEach component is individually wrapped in soft material, and the optical window is covered with a protective cover.

7. storeReturn the disassembled item to its original box and store it in a dry, clean, and dark environment.

Following the above process can maximize the protection of your valuable equipment, ensuring that it can quickly restore performance and greatly extend its service life in the next use. Clear optics and a clean and dry inner cavity are the basis for obtaining accurate photoelectrochemical data.
