Detailed information
This replacement foam insert is the core component of the Bürkle mercury collector, designed to safely absorb spilled mercury. It is made from a special plastic foam with a unique pore structure that effectively soaks up mercury droplets when pressed onto them. The insert attaches to the screw cap of the mercury collector, allowing the collector to be reused when the original insert becomes saturated or worn. By gently pressing the foam insert onto spilled mercury, its pores open and capture the mercury beads. When the cap is screwed back on, the captured droplets pass through a perforated plate into the secure collection container. The replacement insert matches the original in both material and size: a highly durable special foam that does not shed fibres and does not react adversely with mercury.
Typical application area of the product
Used in laboratories, chemistry rooms, or production facilities where mercury is handled (e.g., thermometers, barometers, laboratory experiments). In the event of a mercury spill, the collector with this insert allows for uncomplicated and safe removal of the toxic metal beads. The replacement foam insert ensures that the mercury collector can be kept ready for use at all times — a crucial aspect of workplace safety. This insert is especially important in schools, universities, or pharmaceutical companies where mercury thermometers are still in use, ensuring that, in case of breakage, the mercury can be removed completely and collected for recycling or disposal.
