Description
Volumetric flask with plastic stopper NS 7/16, clear, Class A, 5 ml is a small-volume precision vessel for accurate preparation and dilution of standard solutions in analytical chemistry. The clear glass body allows easy visual inspection of contents and meniscus, while the Class A rating supports careful volumetric work in research, quality control, and teaching laboratories. A plastic stopper matched to the NS 7/16 joint provides a practical seal for mixing and short-term holding of prepared micro-scale solutions. With a nominal capacity of 5 ml, the flask is well suited to low-volume standards, concentrated stock dilutions, and assays where only small defined volumes are required. These flasks from manufacturer Dinkelberg come as a pack of 10 pieces, ideal for benches that run multiple parallel micro-preparations or shared student and routine workflows. Typical applications include preparation of calibration standards, volumetric dilutions, and quantitative wet-chemistry steps that depend on tightly defined solution volumes at the millilitre scale. Handle and clean according to standard laboratory practice for volumetric glassware to preserve clarity, markings, and joint performance over repeated use.

Questions about Flask, volumetric with plastic stopper NS, 7/16, clear, Class A, 5ml, 10/PK
What is this article?
Flask, volumetric with plastic stopper NS, 7/16, clear, Class A, 5ml, 10/PK is the article on this page. Luminix Health distributes Dinkelberg for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Labware.
A volumetric flask is calibrated to contain one volume at a reference temperature, with a single mark on a narrow neck. Class A is the tight tolerance. It is not a storage bottle and it is not for heating. The stopper is part of the calibrated article.
Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
