Standard Tapered Mouth Quartz Glass Test Tube with Stopper Plug

Size: D=diameter*L=length

High-quality quartz glass test tube featuring a standard taper (14/19/24/29) ground glass mouth and an included matching stopper. Made from pure optical quartz, it offers excellent UV light transmission and superior heat resistance.

The standard tapered joint ensures a tight, leak-proof seal with other 14/23 glassware, while the stopper prevents contamination and evaporation. Ideal for sample storage, gas-free reactions, and spectrophotometry.

Durable, reusable, and chemically resistant for demanding lab use.

Quartz Glass Features–

Physical Properties:

It has an extremely low coefficient of thermal expansion (~5.5 x 10⁻⁷/K), granting exceptional resistance to thermal shock. Its softening point is above 1650°C, and it can be used continuously at 1100°C. Quartz glass is highly transparent across a broad spectrum, from deep ultraviolet (UV) to near-infrared (IR). It possesses high dielectric strength and excellent electrical insulation properties even at elevated temperatures.

Chemical Properties:

The material is chemically inert to most substances. It has outstanding resistance to weathering and demonstrates low reactivity with acids (except hydrofluoric and hot phosphoric acid) and molten metals. Its high purity results in minimal contamination in sensitive processes. However, it is susceptible to devitrification (crystallization) at prolonged high temperatures, which can degrade its thermal and optical performance.
