Superior properties needed? The right material to use is fused quartz!
Chemical purity, thermal shock resistance, light transmission and other advanced performance characteristics are superior properties demanded by labware applications.
Quartz offers excellent thermal, electrical, mechanical and optical properties that provide a very high performance for an extensive range of applications through industry.
Fused quartz purity levels are unmatched in the glassware industry and superior to borosilicate products.
The chemical purity and inertness of quartz are essential to many laboratory applications. For example, it can be highly problematical if a lab vessel reacts with its contents and affect the outcome of test. Therefore, the chemical purity is critical and one of the main reasons why many users choose fused quartz vessels.
Supreme thermal properties
Fused quartz beats borosilicate when it comes to heat. Fused quartz is a very stable material at room temperature. At high temperatures, it behaves like all glasses. It does not experience a distinct melting point as crystalline materials.
Fused quartz products can be heated to 1150C under minimal load conditions. It can be quenched into cold water without cracking, due to its high thermal shock resistance. The annealing point is 1140C; strain point is 1070C and fusion point is between 1700C and 1800C.
Quartz flasks are used routinely in petrochemical industry for heating materials such as gasoline. If borosilicate flasks were used instead the borosilicate flasks could break and create a fire.
Because of the exceptional high temperature properties and the low coefficient of expansion flasks made of fused quartz do not break due to the heat or temperature shock. It saves time and money. The initial cost is more expensive but is much safer and will also last longer making them a cost effective solution.
Quartz is also very inert and then, extremely chemical resistant.
A glass cup, for instance, can react with the solution it contains and may corrupt the solution contained. Fused-quartz labware is highly resistant to attack by almost all acid and alkaline solutions, even at high temperatures.
Quartz is also an excellent electric insulator. Both electrical insulation and microwave transmission properties are retained at very high temperatures in many applications.
We can actually say that due to the fused quartz properties it can be used and it’s ideal for many industrial applications.
