· 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

· Cause minimal shedding and reduce evaporation

· Maintains tight fit after repeated use and removal
