Laboratory Glass Cup with Spout, Boro 3.3, Measuring Cup (250 ml, 2)

• Laboratory beaker borosilicate glass 3.3
• DIN 12331, ISO 3819

Straight storage jars with graduation and tip. Made of high-quality borosilicate glass LBG 3.3. Complies with DIN 12331, ISO 3819 LBG 3.3 is a borosilicate glass with a minimum silicon content of 80% and very low coefficient of expansion (3.310-6 K-1) of the borosilicate group of the type 3.3 inches defined by the ISO 3585. Used in products where chemical resistance, mechanical strength and resistance to temperature fluctuations are combined and is produced by the unique combination of properties of the type of reference glass with which most laboratory products. Physical and chemical properties: low weight (@ 20/300 oC): 3.310-6 K-1. Detection temperature (strain point): 520 oC. Tyre temperature (annealing point): 560 ± 10 oC. Softness temperature (softening point): 820 ± 10 oC. Density: 2.2. = = = 002 cm / Class 3 hydrolytic resistance (depending on water class 098)
