HDPE(High density polyethylenewide-mouth bottleCorrosion resistant and sturdy, good storage and maintenance can extend the service life and avoid sample contamination. The technique is simple and easy to operate, and the core revolves around "avoiding injury, preventing pollution, and ensuring sealing":

1、 Storage points

Avoid harsh environments: Keep in a dry, ventilated, and cool place, away from high temperatures (such as near an oven or direct sunlight). HDPE is prone to deformation at high temperatures; At the same time, stay away from sharp objects to prevent the bottle from scratching.

Reasonable placement: Do not stack too high, especially for bottles with heavy objects, to avoid deformation and leakage of bottom bottles under pressure; Empty bottles can be stored upside down to reduce dust from entering the bottle.

Classified storage: Different samples (such as chemical reagents, sample solutions, solid particles) should be placed separately, and the bottle body should be labeled to avoid confusion; For samples with strong corrosiveness such as strong acid and strong alkali, it is necessary to confirm the compatibility of HDPE material (most acids and bases can be stored, but strong oxidizing reagents need to be cautious), and it is safer to store them separately.

2、 Maintenance skills

Cleaning method: Clean the bottle promptly after use, wipe the bottle body and mouth with warm water and neutral detergent, avoid using strong corrosive cleaning agents (such as concentrated hydrochloric acid and strong alkaline solutions), and prevent corrosion of the bottle body; After cleaning, rinse with clean water, invert and dry to prevent residual moisture from breeding bacteria.

Sealing maintenance: The sealing ring of the bottle mouth (if any) should be regularly inspected. If aging, cracking, or deformation is found, it should be replaced in a timely manner to ensure the sealing effect; Do not forcefully pull or tug on the sealing ring during cleaning. After washing, wipe dry before reinstalling.

Check for wear and tear: Before each use, simply inspect the bottle body. If there are obvious scratches, deformations, cracks, or if the bottle mouth is not tightly sealed, do not continue to use to avoid sample leakage or contamination; Long term unused bottles should be washed and dried, then the bottle cap should be tightened and stored in a dry place to prevent dust from entering and the sealing ring from aging.

3、 A small reminder

　　HDPE wide mouth bottleAlthough corrosion-resistant, avoiding long-term storage of highly oxidizing and organic solvents such as acetone and toluene may accelerate the aging of the bottle body; When storing, do not let the bottle directly touch the ground. It can be placed on a tray or shelf for cleaner and easier maintenance.
