LABEXACT

LABEXACT Grade 40 filter paper is a quantitative ashless paper with medium porosity and a thickness of 0.2 mm, suitable for general gravimetric analysis where moderate flow rates are acceptable. Grade 541 is a hardened ashless paper with fast porosity, also 0.2 mm thick, designed for applications requiring higher flow rates or resistance to aggressive chemicals. Both are ashless, meaning they leave minimal residue upon ignition, but Grade 541's hardened surface provides greater wet strength. The choice depends on the specific filtration speed and mechanical durability needed for your analysis.

Yes, LABEXACT 934-AH grade glass microfiber filters are binder-free. This means they contain no organic binders, which reduces extractables and makes them suitable for high-temperature applications (e.g., up to 500°C) or for use in gravimetric analysis where binder weight could interfere. The 934-AH grade has a pore size of 1.5 µm and a thickness of 0.43 mm, available in diameters such as 4.25 cm and 5.5 cm. These filters are commonly used for air monitoring, wastewater testing, or as pre-filters in laboratory setups.

The LABEXACT non-sterile syringe filter (SKU 12K964) has a maximum capacity of 100 mL. It features a 25 mm housing diameter with a 0.22 µm PTFE membrane and polypropylene housing. The inlet connection is a female Luer Lock, and the outlet is a male Luer Slip, making it compatible with standard syringes. This filter is designed for sample preparation, such as sterilizing or clarifying small volumes of aqueous or organic solutions, though it is non-sterile and intended for laboratory use where sterility is not required.

LABEXACT PES membrane filters (e.g., SKU 829WL4, 90 mm diameter, 0.2 µm pore size) are non-sterile, meaning they are not pre-sterilized by the manufacturer. However, the 0.2 µm pore size is suitable for sterile filtration if the filter is autoclaved or otherwise sterilized by the user before use. The polyethersulfone (PES) material offers low protein binding and high flow rates, making it appropriate for biological or pharmaceutical applications. Always verify compatibility with your specific sterilization method and solution chemistry.

LABEXACT C grade glass microfiber filters (e.g., SKU 12K889, 9 cm diameter, 1.2 µm pore size, 0.28 mm thickness) are designed for general laboratory filtration where high loading capacity and fast flow rates are needed. They are often used for pre-filtration of samples with high particulate content, such as in environmental testing (e.g., suspended solids analysis) or as a pre-filter for membrane filters. The C grade offers a balance between particle retention and flow, suitable for routine qualitative or quantitative analysis.
