Glass stirring rods

Introduction to Glass stirring rods

Glass stirring rods are cylindrical laboratory tools used for mixing chemicals, dissolving solutes, and guiding liquid flow during pouring. Thanks to their chemically inert glass material, they do not denature experimental solutions, while their smooth surface minimizes sample adhesion and facilitates cleaning after use.

Important criteria when selecting glass stirring rods are diameter and length, ensuring compatibility with the height and volume of the beaker or sample container. Currently, Hoa Viet supplies glass stirring rods in dimensions such as 150mm, 4x100mm, 6x200mm, and 9x300mm from Assistent (Germany) and Eulab. Depending on operational requirements in Erlenmeyer flasks, beakers, or test tubes, customers can contact Hoa Viet for advice on suitable specifications.

How to select the right glass stirring rod size for sample containers?

The length of the glass rod should exceed the rim height of the beaker or container to ensure a comfortable grip and easy stirring. For small containers, sizes of 4x100mm or 150mm are recommended, whereas larger vessels are better suited for 6x200mm or 9x300mm rods.

Which brands of glass stirring rods does Hoa Viet currently supply?

Hoa Viet distributes glass stirring rods from Assistent (Germany) and Eulab, offering various specifications in length and diameter.

How do glass stirring rods assist in pouring liquids?

When pouring liquids, the operator rests the rod against the beaker spout and directs its tip toward the inner wall of the receiving vessel to guide smooth flow. This technique ensures precise fluid guidance and prevents chemical splashing.

What precautions should be taken to maintain and avoid breaking glass stirring rods?

Do not use the rod to crush solid chemical lumps or strike forcefully against the vessel bottom to avoid chipping or cracking. After exposure to high temperatures, allow the rod to cool naturally before washing with cold water to prevent thermal shock.
