reusable glass filter holder
The reusable glass filter holder represents a sustainable and efficient solution for laboratory filtration needs. This precision-engineered apparatus features high-quality borosilicate glass construction, ensuring durability and chemical resistance while maintaining optimal visibility during filtration processes. The holder's design incorporates a secure locking mechanism that creates an airtight seal, preventing leakage and maintaining consistent filtration pressure. Its versatile configuration accommodates various filter media sizes, typically ranging from 47mm to 90mm in diameter, making it suitable for diverse laboratory applications. The holder consists of a funnel top, a support base with a fritted glass disc, and spring-loaded clamps that ensure even pressure distribution across the filter surface. The ground glass joints provide excellent sealing properties, while the standardized connections allow for easy integration with vacuum systems. The transparent nature of the glass construction enables real-time monitoring of the filtration process, allowing researchers to observe sample separation and flow rates directly. Additionally, the holder features specialized grooves that promote uniform sample distribution and prevent filter paper deformation during use.
