• HEAVY FILTER || Heavy filter funnel (60º Angle) with 7mm diameter plain stem - Heavy construction provides greater mechanical strength and prolonged life with harder than normal usage
• THICK, UNIFORM WALLS || Features thick, uniform walls that allow for increased durability, ease of use and continual flow of liquid
• DURABLE & STURDY || Made of high quality Borosilicate 3.3 glass that is built to last and withstand multiple uses - Glass is the material of choice for laboratory applications due to its inertness
• FILTER PAPER NEEDED || In addition to funnel, filter paper is required to correctly separate solids and liquids - Can be used with various sizes of paper
• MEASUREMENTS || Funnel measures 50mm in diameter - Stem has diameter measuring 7mm

This high quality, borosilicate glass funnel filter is manufactured with a 60 degree angle. It has a 5 cm diameter and a 5 cm stem length.
Autoclavable, with superior chemical durability. Low temperature gradient- can withstand high temperatures & thermal shocks. Eisco Labs Borosilicate glass has the following heat tolerances: Strain Point -515°C | Annealing Point 565°C | Softening Point 820°C.
