ISOLAB is one of the leading producers in the world that manufactures blanks for the complete volumetric line. All of them are manufactured from the best quality of borosilicate glass tubings. Moreover, volumetric and physical controls are done during each step of the blank production in order to achieve the highest quality level.

After the production of in-process goods, every single blank product controlled for its volume level so that the meniscus line matches the ideal height and position on the body.
Following the quality control and rigorous examination of the blanks, they are sent to a tunnel furnace where the stress in the bodies is eliminated under controlled heating and cooling process.

This process gives the optimum mechanical stability which is a must for keeping the constant volume stability in case of temperature fluctuations.
