Micro Cover Glasses and Cover Slips
Marienfeld Superior™ Cover Glass
D 263® M Cover Glass for Microscopy
D 263®M is a clear borosilicate glass that is produced by a draw-down method. This permits the production of very thin glass thicknesses between 0.10 and 0.21 mm.
D 263®M is used as cover glass for microscopic analyses and complies to all requirements of ISO 8255-1. Its low autofluorescence and high chemical resistance are preconditions for reliable research results.
Due to the protective coating and outstanding quality of material it is easily separable, and therefore well-suited for automated cover slipping.
Applications: Light and fluorescence microscopy, especially in medical and biological science.
Features- High spectral transmission
- Refractive index optimized for microscopes
- Virtually colorless
- Low autofluorescence
- Excellent optical and cosmetic qualities
- Good chemical resistance to environmental conditions
- Long durability in archived samples
- Low flatness deviations
- Complies precisely with set thickness tolerances
- Low alkali content enables cell growth
- Good wettability on both glass surfaces
- Protective coating facilitates automated glass separation in coverslippers

Marienfeld Superior™ Cover Glass
Marienfeld Superior cover glass features excellent flatness and smooth surfaces using the highest quality borosilicate glass. Even when archived for years, preparations keep their optical quality thanks to noncorroding glass and the particularly low tolerance of the material thickness. Precise machining processes ensure that these coverslips are precisely cut and sized, with stringent, integrated quality control.
- Ready for sue and non-sticking for application in automated coverslippers
- Made of chemically resistant borosilicate glass D 263®M of the first hydrolytic class
- Absolutely colorless, perfectly clear, suitable for fluorescence microscopy
- In compliance with DIN ISO 8255
- For in-vitro diagnostic (IVD) applications according to IVD directive 98/79/EC, with CE-mark and batch number for comprehensive information and traceability

Marienfeld Superior™ Precision Cover Glass
Thickness No. 1.5H (tol ± 5 µm) for high-performance microscope objectives.
Compliance with the nominal thickness has a critical impact on imaging quality. Thickness variations reduce image contrast and produce image defects, particularly spherical aberrations. This high-precision cover glass with thickness No. 1.5H features exceptionally accurate thickness of 170 µm ± 5 µm. This state-of-the-art cover glass is ideal for objectives with high numerical aperture and high resolution, such as:
Dry Objectives | N.A. > 0.7 |
Objectives for Water Immersion | N.A. > 1.0 |
Objectives for Glycerol Immersion | N.A. > 1.2 |
Objectives for Oil Immersion | N.A. > 1.3 |
- Made of chemically resistant borosilicate glass D 263®M of the first hydrolytic class
- Absolutely colorless, perfectly clear, suitable for fluorescence microscopy
- In compliance with DIN ISO 8255
- For in-vitro diagnostic (IVD) applications according to IVD directive 98/79/EC, with CE-mark and batch number for comprehensive information and traceability

Marienfeld Superior™ Cover GLass 0.4 mm for Counting Chambers and Hemocytometers
Hemocytometer cover glass is used to cover specimens in counting chambers. The cover glass is placed on the outer supports and adheres extremely well, forming an exact capillary gap defining the volume of the cell suspension over the counting grid. High edge quality makes this glass ideal for blood smears.

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, transparent polymer that can be sectioned using a microtome and is able to withstand high temperatures (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
- 0.2 mm (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
