Glass Rod

Glass Rod for Laboratory and Industry Use Glass rod, also called stirring rod, stir rod or solid glass rod, commonly uses borosilicate glass and quartz as material. Its diameter and length can be customized according to your requirements. According to different diameter, the glass rod can be divided into laboratory used stirring rod and sight glass used rod. Glass rod are corrosion resistant. It can resist most acid and alkali. It has strong hardness and can work in 1200 °C high temperature for long time. Thanks to these features, stirring rod is widely used in laboratory and industry. In laboratory, stirring glass can be used to speed up the mix of chemical and liquid. It can also be used to do some experiments. In industry, glass rod are used to produce gauge glass. Four pieces of stirring rod with clear surface. GR-01: Straight thin stirring rod are commonly used in laboratory.Two piece of large glass rod with clear surface. GR-02: Glass rod with well polishing surface and edge. A hand is measuring rod diameter of glass rod with digital vernier caliper. GR-03: All the glass rods are produced in strict quality control system.A hand is measuring glass rod length with meter ruler. GR-04: All the glass rod are produced according to the International Standard and industrial standard. Specification Material: soda-lime, borosilicate, quartz. Diameter: 1-100 mm. Length: 10-200 mm. Color: pink, silver gray or as customers' requirements. Surface: polishing. Thermal properties: Glass rod thermal properties Material Soda-lime Borosilicate Quartz SIO2 content 60% - 75% > 81% > 90% Coefficient of thermal expansion 8.6 × 10-6 3.3 × 10-6 5.5 × 10-7 Softening point 726 °C 820 °C 1780 °C Melting point 780 °C 1680 °C 2000 °C Annealing point 546 °C 560 °C 1120 °C Working temperature 400 °C 500 °C 1200 °C Features and advantages Corrosion resistance The glass disc especially quartz can resist acid and alkali. The quartz do not react with any acid, excep....
