Ideal for microbiology and preparation of HPLC solvents

The Stericup™ vacuum filtration system is the most efficient single-use, disposable Bottle Top Filter process for sterile media preparation. It combines a Steritop™ filter unit with a receiver flask for processing and storing volumes from 150 mL to 1000 mL in a single, ready-to-use format.

Ensure quality control in routine microbiological filtering. Sartorius Nongridded Sterile Cellulose Membrane Filters are single-packed membranes used for colony counting, particle testing, microscopy and sterility testing.

Combines high loading capacity with fine particle retention. Whatman™ Binder-Free Glass Microfiber Filters, Grade GF/A are ideal for gravimetric determination of airborne particulates, stack sampling and absorption methods of air pollution monitoring.

Designed for a wide range of analytical and research applications. MF-Millipore™ Mixed Cellulose Ester Membranes, 0.45μm pore size are available in a range of diameters. Composed of mixed cellulose membrane in black or white with a plain or gridded surface.

Provides highly effective filtration area in a small size. Whatman™ Polycap Disposable AS Capsules, AS 36 filters large volumes and difficult samples with ease.

Sterile Funnels, ready-to-use

Pleated to save time and achieve optimal fit in conical filter funnels. Whatman™ Qualitative Filter Paper: Grade 595 ½ Pleated Circles provide extra surface area to increase total loading capacity.

Supports collection of coarse and gelatinous precipitates with minimal fiber shredding, even when wet. Whatman™ Grade 54 Quantitative Filter Paper has a hard, smooth surface to sustain vacuum and suction filtration.

Designed for easy handling and maximum safety in air filtration. Sartorius™ Midisart™ 2000 PTFE Air Filter entirely eliminates moisture breakthrough because of its inherently hydrophobic PTFE membrane reinforced with polypropylene gauze. Stepped hose barb connectors ensure a simple and secure hold.

Use for analyses of airborne contaminants and other particles using optical or electron microscopy. Isopore™ Polycarbonate Membrane Filters have a smooth, glass-like surface for clearer sample observation. Available in a variety of pore sizes/flow rates, diameters and colors.
