TNL1320/TNL1345 Disposable Nylon Syringe Filters, 13 mm, 0.20 µm and 0.45 µm (CAT#: STEM-AL-3318-ZJF)

TNL1320/TNL1345 Disposable Nylon Syringe Filters, 13 mm, 0.20 µm and 0.45 µm are designed for general filtration of aqueous samples, organic solvents, and HPLC, GC, or IC sample preparations. The filter medium is nylon. The series provides a 13 mm housing with 0.20 µm and 0.45 µm pore-size options. The nylon membrane provides mechanical strength and chemical stability across both aqueous and organic filtration workflows. The housing is medical-grade polypropylene with a female Luer-lock inlet and a male Luer-slip outlet. The documented maximum operating temperature is 45 °C, and the stated pressure limit is 100 psi. The documented filtration area is 0.78 cm², while the residual volume is <30 µL after air removal. Batch-level HPLC and ion-chromatography checks are described for extractable control and analytical compatibility. Each model is supplied as 400 filters per box for single-use sample preparation.
