Electron Microscopy Sciences Borosilicate Capillary Micro Glass Slide, 0.40x4.0 mm

Electron Microscopy Sciences Micro glass slides are precision rectangular glass capillary tubes for use in microscopic viewing of liquid samples. Capillary action instantly collects the sample and the thin glass walls minimize evaporation. The design of these cells eliminates the needs for cover glass and the hanging drop method. Made from corning 7740 borosilicate, low expansion, type i glass, these micro glass slides can withstand heat up to 500 degree c. Samples can be retained for future reference by sealing or cementing open ends. Micro glass slide are packaged in plastic vials. I.d. Tolerance +/- 10% and wall tolerance +/- 20%. - EMS
