How can I determine which side, of your Nunc Thermanox Coverslips, is cell culture-treated?

A simple method, to determine which side of our Nunc Thermanox Coverslip is cell cultured-treated, is the "droplet" test. A drop of water or culture medium will spread on the hydrophilic, cell culture treated side.
Please review the following procedure for the "droplet" test:
- Put a drop of sterile media or water on the coverslip
- If the droplet forms a bead, then that side of the coverslip is not treated
- If the droplet spreads evenly over the coverslip, then that side of the coverslip is treated
Additionally, the coverslips are packaged so the cell culture-treated side faces the label.

What is Thermanox plastic?

Thermanox is a trademark name for a particular type of polymer in the polyolefin family.

How can I tell which side of your Thermanox coverslips is treated?

If Thermanox coverslips are still in the original packaging, the side facing the label is treated. If they have been removed, there is another way to determine this: hold one with forceps at a slight angle to the horizontal and dispense a few drops of sterile water onto the surface. On the untreated side the water will bead up tightly as it runs off, but on the treated side it will spread out much more due to the hydrophilic surface modification.
