Graduated flasks
Volumetric flasks provide precise results in chemistry and pharmacy. They are not scaled, but have a single ring mark that is drawn all the way round the neck to avoid reading errors.
The narrow neck results in high setting accuracy. In addition, volumetric flasks have bulbous curves in the upper area so that any gas bubbles that form can escape from the solution more easily. However, if there are gas bubbles in the solution, the volumetric flask must be swivelled slightly so that the bubbles rise to the top. In addition to volumetric pipettes and burettes, volumetric flasks are therefore the most accurate volumetric instruments in the laboratory for analysis.
Wide-mouth bottles, square, natural, HDPE
The square LABSOLUTE® wide-mouth bottles made of HDPE are ideal to store liquid, powdery and paste-like samples. Due to their wide-opening the bottles can be easily filled. The angular shape ensures that the storage space in cupboards and drawers is used optimally.
The black lids made of PP (7.664 458) with a diameter of 60 mm and PE foam insert must be ordered separately....
Square Media Bottles Nalgene™ Typ 2019, PETG, sterile
With white HDPE screw closure. Reduced permeability to CO 2/O 2 which reduces pH-shift. Bottles and closures are radiation-sterilised and pyrogen-free to eliminate costly washing, depyrogenation and autoclaving steps. Heatshrink band around closure and neck provides tamper-evident seal. Packed in shrink-wrapped trays. 2L size has molded-in handgrips and a 53-mm (53B) white closure. Bottles are sterile to 10-6 SAL, non-pyrogenic, non-cytotoxic and comply with USP Class VI guidelines. Sterile. Transparent. Leakproof. Graduated....
