Available with #1.5 （0.16 – 0.19 mm） thickness. Packaged in convenience size: 100 per box

Quartz Microscope Slides and Coverslips

There are many applications that require slides and coverslips that have absolute UV transparency, and high temperature properties. EMS now is introducing the highest quality, clear fused quartz microscope slides and coverslips to meet all of these requirements.

• The window of highest transparency to UV is between 0.15µ to 5µ.
• Typical flatness measured 2 to 4” bands per inch.
• Soften point is about 1250°C （2282°F）.
• Standard microscope slide thickness is 1 mm.
• Standard coverslip thickness is 0.2 mm.

Superslip® Micro Glasses

Finally, your automated coverslipper has the right coverslip to allow it to run smoothly.

These “Superslip®” coverslips are designed to work in automatic coverslip machines and humid environments without sticking or jamming up in the middle of a run.

These new superslips combine specialized production procedures with our unique moisture-resistant packaging which brings you superior coverslips.

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 –70ºC to +150ºC）. 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
