Product Description
Why PVA Sponges? There are several reasons why PVA (Polyvinyl alcohol) sponges may be preferred over cotton for test tube setups:
- Mold Resistance: Cotton molds easily which is a concern if it is yellow, green, or pink. PVA sponges are more resistant to mold than cotton.
- Durability: PVA sponges are more durable than cotton.
- No Threading: Cotton threads easily when pulled on by ants and they can get dangerously caught up in the threading.
