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 4797. Without stopper. Compatible with all stoppers with standard ground joint made of glass or plastic.

LABSOLUTE® round bottom flasks made of high-quality borosilicate glass 3.3 comply with the valid standards. They are available in different volumes and have the common ground joint sizes. All LABSOLUTE® round bottom flasks are characterized by very good chemical and temperature resistance. Because of the round shape, the flasks are ideal for consistent heating of liquids. Due to the standard ground joints, the flasks can be easily combined with other glass labware such as condensers.

Comply with DIN EN ISO 4797.

LABSOLUTE® one neck flat bottom flasks are made of high-quality borosilicate glass 3.3 and therefore extremely temperature-resistant up to 500 °C. The flasks comply with the standard DIN EN ISO 4797. They are resistant to cold lyes/alkaline solutions and strong acids with the exception of hydrofluoric acid and concentrated, hot phosphoric acid. Because of the round shape the flasks are ideal for a consistent heating of liquids. The flat bottom guarantees a secure stand on the lab bench. Due to the standard ground joint the flasks can be easily combined with several other glass labware like condensers, etc.
