      In order to assist you I would need to know the diameter of the tubes, not the volume. please email me at and put MikeW in the subject and please include the part number to refresh my memory.

      Normally this product operates at ambient temperatures (4 degrees to 50 degrees C). However if the multipurpose disc (part #07637-23) is used, then this product can be used up to 70 degrees C (the multipurpose disc is made of acrylic and can go up to 70 degrees C). 70 degrees C should be the maximum though.
      Warning: the life of the product will lessen when using it at a higher temperature. Also make sure to keep the humidity down, this also can lessen the life of the product.
