Cover Slips; Thermanox®; TMX Coverslips
NUNC™ Brand Thernanox®, or TMX coverslips are made from a polymer (in the polyolefin family) that is highly resistant to most chemicals. Thermanox® plastic is resistant to alcohols, aldehydes, hydrocarbons, dilute acids (<10%) and dilute alkalis (<2%). TMX has limited resistance to chlorinated hydro-carbons, however, it is not resistant to concentrated acids or bases.Thermanox® plastic is a flexible, trans-parent polymer that can be sectioned using a microtome and is able to withstand high temp-eratures (temperature range –70°C to +150°C). Thermanox® coverslips are culture treated on one side for enhanced cell attachment and growth. The treated side is packaged face up toward the label.
Features:
- Flat and remain flat
- 0.2mm (No. 2) thickness
- Resistant to commonly used solvents
- Safe and easy to handle
- Auto fluorescent in the range 380 to 545 nm
- Thernanox® cover slips can be autoclaved at 20 minutes steam, 20 minutes dry at 120°C

EMS Exclusive Coverslip Holders
EMS introduces an alternative to the standard aluminum slide used to visualize live microscopic organisms (both dorsal and ventral sides) using a pair of coverslips. The holders are made from refined plastic and come in two versions:
The single version, which is designed to hold a pair of cover slips, generally of fixed material, often in gel mount. It allows a specimen to be viewed from both sides on a confocal microscope.
The second version is similar to the first, but in place of it being a single plastic holder, two systems are snapped together and hold a coverslip sandwich in place without the need of any glue. This version holds living material between the coverslips, generally in water.
Both are reusable and made from white ABS plastic.
Total slide dimensions:
3" x 1" x 0.045"
Well dimensions: 25 mm x 23 mm
Inside opening dimensions: 22 mm x 16 mm
Recommended coverslip: 22 mm x 22 mm
