The United Scientific FG5639-500QR Volumetric Flask is the ideal tool for laboratory professionals who need accurate and reliable measurements. With a capacity of 500ml and a tolerance of ±0.20 ml, this flask meets Class A specifications per ASTM E288.
The machine-blown body is made of durable glass, ensuring it can withstand the harshest laboratory conditions. The heavy beaded tubing neck makes it easy to pour liquids in and out of the flask. This flask also features a sharp graduation line and large white block letters, making it easy to read the measurements accurately.
An included ground glass stopper ensures that the flask is airtight, preventing any potential leaks or contamination. This stopper, with a size of 19, fits snugly into the neck of the flask, so you can be sure that it won't come off accidentally.
The United Scientific FG5639-500QR Volumetric Flask is not just accurate and reliable, it is also individually serialized and certified. This means that each flask is individually tested and verified to meet Class A specifications before it leaves the factory, ensuring that you get the highest level of accuracy possible.
What sets this flask apart from other laboratory equipment is its innovative technology only available on United glassware - QR code integration. Each flask features a QR code that you can scan with your smartphone's NeoReader app. This will take you directly to the certificate screen, where you can access certificates of calibration, certificates of conformity, and user manuals, making it quick and easy to verify the flask's accuracy and track its history.
In addition, the United Scientific FG5639-500QR Volumetric Flask comes individually packaged and in a pack of one, so you can be sure that each flask is in pristine condition when it arrives.
