Filter tubes are porous sticks with internal cores of fritted glass used for the purpose of purifying liquefied materials and solutions. These tubes are available in a range of different porosities depending on the gases looking to be absorbed. All models are fabricated from borosilicate glass and boast robust durability under frequent use in standard laboratory procedures. Filter tubes also come in a variety of sizes for solution volumes.
