"Gravimetry"

Supplier: GVS FILTER TECHNOLOGY

Quantitative filter paper, grade DMS40, medium speed filtration with retention range of 7 to 9 μm.

Supplier: I.W. TREMONT CO., INC.

LabExact® Grade VSS is 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 and volatile solids ignited at 550 °C Method 2540E.

Supplier: I.W. TREMONT CO., INC.

Virtually identical to CFP1, but twice as thick, resulting in a significantly slower flow rate with a retention of approximately 6 µm.

Supplier: GVS FILTER TECHNOLOGY

Mixed cellulose esters (MCE) filtration membrane is an unsupported, hydrophilic membrane. Its rapid flow rate and high throughput make it ideal for use in diagnostic kit manufacturing applications.

Supplier: I.W. TREMONT CO., INC.

Very similar basis and thickness to CFP5, but with a slightly less retentive porosity.

Supplier: I.W. TREMONT CO., INC.

LabExact® Grade TSS is a binderless high efficiency (HEPA type) filter mediµm with particle retention of 1.50µm. Liquid filtration properties have been specifically designed for EPA Methods 2540C and 2540D for testing dissolved and suspended solids in water and wastewater.

Supplier: I.W. TREMONT CO., INC.

The fastest flow rate demonstrated by any of the qualitative cellulose filter medias, resulting in a low retention rate of approximately 25 µm.

Supplier: I.W. TREMONT CO., INC.

Grade CFP541 quantitative cellulose filter media is ashless and hardened with increased wet strength.

Supplier: Ahlstrom

Ahlstrom grade 141 is a binder-free microfiber glass filter paper that is an effective pre-filter, offering better filtration speed and a higher loading capacity than an analytical filter paper of similar particle retention.

Supplier: I.W. TREMONT CO., INC.

A more retentive and absorbent media than CFP1, with approximately 8 µm and a medium to slow flow rate.

Supplier: CELLTREAT Scientific Products

Electric pipette controller automates and improves accuracy and precision of pipetting tasks through rapid aspiration and dispensing of liquids.

Supplier: MilliporeSigma

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Supplier: I.W. TREMONT CO., INC.

Demonstrating medium retention and flow rates, this media is widely used in many general quantitative procedures in both liquid and gas.

Supplier: MilliporeSigma

100 μg/ml in methanol (as a free base), ampule of 0.5 ml, Cerilliant®.

Supplier: SPEX CERTIPREP LLC

Sodium thiosulfate is a Carbon Black Reagent designed for ASTM D1510.

Supplier: GVS FILTER TECHNOLOGY

Quantitative filter paper, DME43 grade, medium speed filtration with retention rate of 14 to 17 μm.
