volumetric measurement & liquid handling
VOLUMETRIC FLASKS - “glass” - “class A” - “conformity certified” - “trapezoidal”
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 persistance 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.

VOLUMETRIC FLASKS - “P.P” - “class B”
Manufactured according to DIN EN ISO 1042 standard from clear polypropylene. Resistant to most acids, bases and many commonly used solvents. Calibrated according to DIN/ISO Class “B” standard. Clear flasks are manufactured from very clear polypropylene resulting high transparency and clear indication of meniscus line. Amber flasks are manufactured from special formulated polypropylene preventing UV light penetration into the flask yet still offering high transparency. All volumetric flasks are supplied with a leak-proof P.E stopper which ensures perfect closure. For consistent accuracy should not be used with liquids over 60°C or kept under direct sunlight for long periods. clear flasks amber flasks neck NS size
