JN sciencetech brand PTFE Pressure Equalising Funnel are manufactured from pure virgin PTFE for maximum consistency and homogeneity which results in a “super-smooth” internal surface finish and usable up to 280°C.

     Extraordinary chemical resistance, resistance to almost all chemical solvents and smooth surface , standard liquid filter funnel.  It is suitable for adding liquid to fine-mouth container, and also for injecting liquid into gas generating device to prevent liquid overflow.  Mainly used for trace analysis, isotope detection anlysis and other high end experiments

Simply put, contaminants can leach out of glass and may then be detected in one’s samples even in many of today’s modern instruments of analysis.
