Soft Wood Corks

1. Natural Materials: Commonly fabricated from natural cork, it is environmentally friendly and biodegradable.
2. Excellent Sealing Performance: The cork stopper is capable of snugly adhering to the container mouth, effectively preventing the leakage of gas and liquid.
3. Good Elasticity and Lightweight Nature: The cork material exhibits superior elasticity, can accommodate container mouths of varying sizes, and reverts to its original state after removal. Simultaneously, it is of lightweight, facilitating operation and storage.
4. Chemical Resistance: It demonstrates good tolerance towards the majority of chemical substances and is not prone to corrosion.
5. Reusability: After cleaning and disinfection, the cork stopper can be utilized multiple times.
6. Biocompatibility: In biological laboratories, the cork stopper does not exert adverse influences on biological samples.

Precautions:
1. Size Matching: It is essential to ensure that the size of the cork stopper is compatible with that of the test tube or container opening, so as to ensure an optimal sealing effect.
2. Cleaning: The cork stopper should be cleaned prior to usage to prevent contamination of the experimental sample.
3. Avoid Excessive Compression: When inserting the cork stopper into the container, excessive compression should be avoided to prevent permanent deformation or damage to the container opening.
4. Check Integrity: Before utilization, inspect the cork stopper for any cracks or damages to avoid undermining the sealing performance.
5. Avoid High Temperatures: Cork stoppers are not suitable for high-temperature environments as high temperatures may cause damage to the cork stopper or result in seal failure.
6. Storage Conditions: Cork stoppers should be stored in a dry environment to avoid mold or deformation caused by moisture.
7. Regular Replacement: Even if the cork stopper seems intact, it should be replaced at regular intervals to prevent the negative impact of aging on the sealing effect.
