Flasks

LABSOLUTE® Kjeldahl flasks with a beaded rim without standard ground joint are made of high-quality borosilicate glass 3.3. The neck diameter including rim is around 40 mm for all volumes. The flasks correspond to the standards of the European Pharmacopoeia 7 for glass type I.

The LABSOLUTE® Erlenmeyer flasks with a durable volume scale are made of high-quality borosilicate glass 3.3 and are therefore extremely temperature-resistant up to 500 °C. The wide-neck and narrow-neck flasks, as well as the flasks with standard ground joint comply with the valid standards. The flasks are resistant to cold lyes/alkaline solutions and strong acids, with the exception of hydrofluoric acid and hot, concentrated phosphoric acid.

Comply with DIN EN ISO 24450.
