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.

Permeability Characteristics:

  • Oxygen (ASTM 1927-98): 150 cc/m2 d at 23°C and 50 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

not tight around your legs
Nice socks. They are thin and light weight so they are ideal to wear with snug fitting shoes. They have a nice cable style design to dress them up. I have been wearing a pair all day, and they do not dig into my legs at all. Love that. I have not washed them, but I see no reason why they would not wash up well in cold water and a low dry temperature. The price is great so give them a try.

Nice ruffle socks
First of all, I like the thickness of these ruffle socks. They are not too heavy nor too thin, making them ideal for all seasons wearing. The ruffle edges make the socks unique and beautiful. The quality feels quite good. I like the socks in six different color, all of them are beautiful.

Cute, very breathable material
These socks are super cute and comfy. I love the material-- it's light and very breathable. The ruffles are so cute. I think these socks work great with ankle-high boots or chunky sneakers.
