· Material: Densest foam, densest sponge, and degreasing fiber are available

    Densest foam:

    The material density is moderate and the deformation effect is good, easy to operate and maintain a tight fit to the tube wall after repeated use and multiple movements, high air permeability ensures the growth of drosophila

    Densest sponge:

    Dense material, can completely block the entry of mites, moderate hardness, easy to operate during the experiment, autoclavable, not easily deformed and damaged, and can be reused

    Degreasing fiber:

    Excellent shaping effect makes the internal space compact and prevents mites from entering while still ensuring breathability, cost-effective, recommended for one-time use

    Fiber:

    Fiber has high sealing performance and allows the holes to pass through, thereby ensuring breathability and preventing the entry of mites. The sophisticated technology makes the product have good hardness, can fit closely with the vial wall, and is easy to operate.

· Cause minimal shedding and reduce evaporation

· Maintains tight fit after repeated use and removal
