LabExact Grade 934-AH® Glass Microfiber Filter 0.43 mm Thick, 9.0 cm Dia., 1.5 um, 100 PK

The PTFE Membrane Filter is designed for reliable, high‑throughput filtration in demanding laboratory and industrial applications. Featuring a 0.80 µm retention rating and a hydrophobic PTFE membrane, it is well suited for air and gas monitoring, venting applications, and filtration of non‑aqueous or chemically aggressive liquids. PTFE provides exceptional chemical resistance and thermal stability, ensuring consistent performance in harsh environments. The large 90 mm diameter offers increased filtration surface area, supporting higher flow rates and extended service life. Supplied ...

Grade VSS® - A binder free material manufactured using a proprietary glass chemistry which permits usage in high heat applications beyond typical borosilicate glass blends. Ideally suited for determination of "Fixed & Volatile Solids" Ignited at 550°C Method 2540E. Low fiber shedding improves quality assurance of test results and low percentage of weight loss when used in gravimetric tests. High loading capacity is an attribute of the high surface area and complex pore structure. Material is also compliant with the requirements of standard methods 2540C & 2540D and EPA Method 160.2 ...

Grade TSS - Binderless borosilicate glass microfiber for Total Suspended Solids and specifically designed for EPA Methods 2540C and 2540D for testing dissolved and suspended solids in water and wastewater. High flow rate with high capacity. Media has no added extractables to aid in the elimination of sample contamination. Excellent wet strength. Other common applications include gravimetric analysis of air pollutants, membrane support pads, membrane prefilters, clarification of reagent and buffer solutions, filtration of eluent for HPLC and moisture analysis pads.

Features: Designed with a complex proprietary fused 100% Polypropylene (PP) fibrous matrix which is a lightweight polyolefin Has high chemical resistance to most short term exposure of organic solvents, acids and alkalis 290g/m2 basis weight sufficient to easily handle typical lab bench volume spills up to 600ml safely and quickly. Lays flat as a bench pad with sufficient stiffness reducing "bunch up" seen with other competing brands Soft enough to be used as a wipe Binding dots accumulate fluids and migrate deeper into the pad
