Keep moisture loss to a minimum and protect the integrity of your laboratory and research applications with a flexible covering for test tubes, beakers, petri dishes and more.

  • Resists waters, acids, alkalis and some organic solvents.
  • Clings to itself and irregular shaped openings. Over 300% stretch.

Permeability Characteristics:

  • Oxygen (ASTM 1927-98): 150 cc/m2 d at 23°C and 50 RH
  • Carbon Dioxide (Modulated IR Method): 1200 cc/m2 d at 23°C and 0% RH
  • Water Vapor (ASTM F1249-01): Flat: 1 g/m2 d at 38°C and 90% RH Creased: same as flat
  • Note: Because of low water permeability and the insensitivity of this material to moisture vapor, it is unlikely that differences in relative humidity (RH) will make a difference in the oxygen permeability

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...
