PVA Sponges: The Cotton Alternative


Upgrade your test tube setups with PVA sponges—an alternative to traditional cotton plugs. Purchase includes 10 PVA sponges.

Product Description

Why PVA Sponges? There are several reasons why PVA (Polyvinyl alcohol) sponges may be preferred over cotton for test tube setups:

  1. 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.
  2. Durability: PVA sponges are more durable than cotton.
  3. No Threading: Cotton threads easily when pulled on by ants and they can get dangerously caught up in the threading.
