"Gravimetry"

Supplier: Cytiva

Superior grade glass fiber filters for a variety of air sampling and liquid filtration methods.

Supplier: Advantec MFS

Thicker glass fiber filters with high loading capacity and typically faster flow time are recommended for filtering viscous fluids, such as proteinaceous solutions and gels and as prefilter to extend membrane life.

Supplier: Cytiva

Ideal for sampling airborne metals, silica, and dust.

Supplier: Aladdin Scientific

These products are prepared gravimetrically on a weight/weight basis. Both solute and solvent are weighed on a balance calibrated by Aladdin engineers using OIML traceable weights. Aladdin holds ISO 17025 accreditation for calibration of laboratory balances (INAB ref: 265C). The resulting Balance Certificate of Calibration is issued in accordance with the requirements of ISO/IEC 17025. The concentration of each standard is verified using a high performance top of the range calibrated spectrophotometer. The calibration of the spectrophotometer is controlled using high purity ISO Guide 34 accredited spectrophotometric standards.
