Details:

Here is the corrected text: This 100mL capacity Schellbach burette features a vertical white backing with a central blue line, providing better contrast with the meniscus. Made of high-quality, heavy-duty borosilicate 3.3 glass, it offers excellent durability and chemical resistance. The burette includes a calibration certificate from an ISO-accredited testing laboratory, certifying Class A accuracy with ±0.10mL tolerance as per DIN ISO 385 standards. Chemically resistant 0.2mL blue graduations and markings provide contrast against clear liquids. An attached glass key stopcock allows for precise control of liquid flow. The burette measures 30.5 inches long with an outer diameter of 18mm (0.7 inches). It is autoclavable, with superior chemical durability, and can withstand high temperatures and thermal shocks due to its low temperature gradient. Eisco Labs' borosilicate glass has the following heat tolerances: strain point 515°C, annealing point 565°C, and softening point 820°C.
