Sabirex PFA Flask

Sabirex PFA Flask

It is possible to achieve accurate and high-purity liquid distribution and formulation while eliminating the leaching of trace elements.

The Sabilex PFA volumetric flask has Class A accuracy according to DIN (German Industrial Standards), EN (European Standards), and ISO 1042. Although it is made of PFA, it has relatively high transparency, is easy to clean, has strong resistance to heat and contamination, and possesses excellent surface cleanliness compared to glass containers, minimizing residue of contents. Compared to the push-in stopper of traditional glass volumetric flasks, the screw cap of the PFA volumetric flask is inert and prevents contamination. Its excellent liquid release allows for the complete recovery of samples within the container without loss. It is manufactured from high-purity PFA resin, eliminating the risk of impurity leaching and is inert to almost all chemical solutions.

HARIO beaker, flask

HARIO beaker, flask

Hario's beakers and flasks are made of a heat-resistant glass with a low expansion coefficient called "H-32," which is a type of scientific glassware.

Our company has been selling HARIO glassware such as beakers and flasks as an agent for Shibata Scientific for about 40 years. The H-32 is made of low thermal expansion coefficient heat-resistant glass, and it does not contain heavy metals such as lead, zinc, and cadmium, as well as arsenic and antimony, which are commonly used as foam agents, making it a safe choice for chemical analysis. ■ Currently, we are running a campaign for HARIO beakers and flasks.

Flat-bottom flask made of heat-resistant glass.

Flat-bottom flask made of heat-resistant glass.

The mouth is designed with a durable, thick rim. It can be widely used for measuring, stirring, and culturing.

There are flat-bottom flasks available in sizes ranging from 200ml to 5L. H-32: HARIO-32 is a borosilicate glass with a low thermal expansion coefficient, completed after years of research. It is a glass that meets the "Borosilicate Glass-1" standard specified by JIS, excelling in chemical durability and heat resistance. It does not contain any heavy metals such as lead, zinc, or cadmium, nor does it use sulfurous acid or antimony, which are commonly used as bubble agents in regular glass. Due to its small expansion coefficient, it has high heat resistance, capable of withstanding a temperature shock of 250 degrees with minimal expansion and contraction from heating and rapid cooling.
