ZYBLLQ volumetric flask 100ml

Measuring with measuring instruments is a necessary process in laboratories, especially in the pharmaceutical, food, and testing industries.

Zybllq volumetric flask 100ml，We can provide verification institutions for metrological verification, including provincial and municipal metrology institutes, as well as third-party qualified metrology units.

Zybllq volumetric flask 100ml，At the same time as carrying the certificate, our company will engrave the corresponding traceability management number on the measuring instruments sent for inspection, which will be the "identification number" of the measuring instruments.

• Once received, it can be used to avoid multiple departments going through the process back and forth;

• The independence of measuring instrument numbers, one for each, corresponds one-to-one with the calibration certificate and product testing report;

• The numbering of the measuring instrument is non erasable and not affected by factors such as immersion or friction;

• Management convenience, convenient ledger and other records;

• Intuitiveness, can be numbered according to the unit/product name;

• More scientific, increase the persuasiveness of testing, and occupy new heights in the industry.

Support personalized numbering customization, independent numbering, once and for all, cannot be erased!

volumetric flaskPrecautions for use：

‌Inspection and cleaningBefore use, it is necessary to check for any leakage and carefully clean. ‌

‌Holding methodWhen injecting liquid, only hold the bottleneck on the marked line to prevent temperature changes. ‌

‌Liquid level observationWhen determining the liquid level position, the line of sight and the marking line should be at the same horizontal position. ‌

‌Dissolution and TransferSolute cannot be dissolved in a volumetric flask, it should be transferred after dissolution, and the total amount of solvent used to wash the beaker should not exceed the scale line. ‌

‌temperature controlThe volumetric flask cannot be heated, and the hot solution needs to be cooled to room temperature before transfer. ‌

‌Storage and maintenanceSolution, especially alkaline solution, should not be stored for a long time. After use, it should be washed clean in a timely manner, the bottle stopper should be plugged, and a piece of paper should be sandwiched between the stopper and the bottle mouth. ‌

‌Choose a suitable volumetric flaskIf preparing substances that are easily decomposed by light, brown volumetric flasks should be selected. ‌
