Formulate critical analytical standards and precise chemical dilutions with Heathrow Scientific Class A Volumetric Flasks. For advanced quantitative analysis, high-performance liquid chromatography (HPLC), and trace metal testing, researchers demand absolute volumetric accuracy. These premium borosilicate glass flasks are rigorously calibrated to meet strict Class A tolerances, providing the exact precision required to prepare reliable standard solutions, serial dilutions, and exact-concentration reagents.
The classic flat-bottom geometry offers excellent stability, while the elongated, narrow neck allows the technician to read the solitary calibration mark with precision, virtually eliminating measurement errors. Each flask is paired with a precision-ground solid glass stopper that creates an airtight, hermetic seal. This completely prevents the evaporation of highly volatile solvents and protects sensitive internal solutions from ambient atmospheric contamination. Currently available in highly specialized 1 mL and 2 mL micro-capacities for ultra-fine analytical compounding.
