- Manufactured from heat resistant, borosilicate glass 3.3
according to DIN EN ISO 1042 standard. - Trapezoidal body form offers much higher stability and
avoids fall over risk. - Calibrated according to DIN/ISO Class “A” standard.
Featured with a (“DE-M”) conformity mark according to - German Federal Weights and Measures Regulations.
Individual calibration carried out by automatic robots
eliminate possible deviations from nominal values. - Conformity mark and batch number printed on the body
surface. Batch certificate can be downloaded from website. - Diamond grinded meniscus ring mark offers longer
persistence and enables easy observation of meniscus level.
Inscriptions on the flask bodies are printed with long lasting
enamel color. - All volumetric flasks are supplied with a leak-proof P.E
stopper which ensures perfect closure.
Small size flasks with standard body shape can fall over very easily due to their smaller center
of gravity.
Compared to other standard volumetric flasks of the same volume, trapezoidal flasks have at least twice base area.
For this reason trapezoidal flasks are much more stable than standard flasks.
