Superior ConstructionVacuum filter holders are built using borosilicate glass stands and polypropylene funnels, finished with stainless steel clamps and silicone stoppers. This combination ensures optimal durability and high resistance to chemical exposure, making them dependable for diverse filtration needs. The easy assembly and disassembly mechanism streamlines cleaning and maintenance in fast-paced laboratory environments.
Versatile CompatibilityDesigned to accept standard membrane diameters of 47 mm or 50 mm, these filter holders suit a wide variety of filtration membranes. Their funnel capacities range from 300 ml to 500 ml, accommodating various sample volumes. The compatibility with different stopper sizes ensures adaptability to specific operational requirements, making them reliable across pharmaceutical, water, and food testing labs.
Reliability and SafetyThese vacuum filter holders operate safely under a maximum pressure of 0.2 bar and temperatures up to 100C. The materials used, such as borosilicate glass and polypropylene, ensure they withstand autoclaving at 121C. Their reusable design, combined with high chemical resistance, ensures a secure and prolonged performance during repeated lab cycles.
FAQs of VACCUM FILTER HOLDERS:
Q: How do I assemble and use the vacuum filter holder for laboratory filtration?
