The Bohlender b.safe Funnel 130 S 60 (Ø 130 mm) is crafted from static-dissipative PE‑EX, offering safe and efficient disposal of liquid waste in laboratory environments. Equipped with a hinged lid to minimize vapor escape and a removable sieve to retain solids, this funnel features an integrated level indicator for monitoring fluid levels in opaque containers. Engineered for secure attachment to waste vessels via a freely turnable cap, it also includes a 1.5 m grounding cable for static protection.
This funnel ensures safe, spill-free waste handling in HPLC, organic synthesis, and general lab use, while the level indicator adds a visual safety check to prevent overfilling.
