Whatman Laboratory Filtration

Whatman Laboratory Filtration

These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.

Grade 1: 11 µm
The most widely used filter paper for routine applications with medium retention and flow rate. Extended range of sizes includes 10 to 500 mm diameter circles and 460 x 570 mm sheets. This filter is also available in theFilterCup, this is a convenient, disposable 70 mm filter funnel with a 250 ml capacity molded from polypropylene with an integral, heat bonded filter (catalog number 1600-001).

This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids. Traditionally the grade is used in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate.

In agriculture, it is used for soil analysis and seed testing procedures. In the food industry, Grade 1 is used for numerous routine techniques to separate solid foodstuffs from associated liquid or extracting liquid and is widely used in education for teaching simple qualitative analytical separations.

In air pollution monitoring, using circles or rolls, atmospheric dust is collected from airflow and the stain-intensity measured photometrically. For gas detection, the paper is impregnated with a chromogenic reagent and color formation quantified by optical reflectance.

Grade 2: 8 µm
Slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed). More absorbent than Grade 1. In addition to general filtration in the 8 µm particle size range, the extra absorbency is utilized, for example, to hold soil nutrient in plant growth trials. Also used for monitoring specific contaminants in the atmosphere and in soil testing. Also available prepleated asGrade 2V.

Grade 3: 6 µm
Double the thickness of Grade 1 with still finer particle retention and excellent loading capacity; more precipitate can be held without clogging. The extra thickness gives increased wet strength and makes this grade highly suitable for use in Büchner funnels. The high absorbency is particularly valuable when the paper is used as a sample carrier. This filter is also available in the FilterCup. This is a convenient, disposable 70 mm filter funnel with a 250 ml capacity molded from polypropylene with an integral, heat bonded filter (catalog number 1600-003).

Grade 4: 20-25 µm
Extremely fast filtering with excellent retention of coarse particles and gelatinous precipitates such as ferric hydroxide and aluminum hydroxide. Very useful as a rapid filter for routine clean-up of biological fluids or organic extracts during analysis. Used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical.

Grade 5: 2.5 µm
The maximum degree of fine particle filtration in the qualitative range. Capable of retaining the fine precipitates encountered in chemical analysis. Slow flow rate. Excellent clarifying filter for cloudy suspensions and for water and soil analysis. Also available prepleated as Grade 5V.

Grade 6: 3 µm
Twice as fast as Grade 5 with similar fine particle retention. Often specified for boiler water analysis applications.

Grade 591: 7-12 µm
A thick filter paper with very high loading capacity for fast filtration of medium to coarse precipitates. Offers high absorbency and increased wet strength. Also available prepleated as Grade 591 ½.

Grade 595: 4-7 µm
Very popular, thin filter paper, medium-fast with medium to fine particle retention. Used for many routine analytical applications in different industries, (e.g., particle separation from food extracts or filtration of solids from digested environmental samples, e.g., for ICP/AAS analysis). Also available prepleated asGrade 595 ½.

Grade 597: 4-7 µm
A medium fast filter paper with medium to fine particle retention. Used for a wide variety of analytical routine applications in different industries like food testing (e.g., determination of fat content) or removal of carbon dioxide and turbidity from beverages (e.g., beer analysis). Available prepleated as Grade 597 ½.

Grade 598: 8-10 µm
A thick filter paper with high loading capacity. Combines medium retention with medium-fast to fast filtration speed. Also available prepleated as Grade 598 ½.

Grade 602 h: < 2 µm
A dense filter paper for collecting very small particles and removing fine precipitates. Used in sample preparation, e.g., in the beverage industry for residual sugar determination, acidic spectra, refractometric analysis, and HPLC. Available prepleated as Grade 602 h ½.

Our History

Established in June 1967 as Minnesota (3M) Sdn. Bhd., the company housed its 9 employees and all its inventories in a 1,500sq.ft.room.

In order to accommodate its expanding operations, the company relocated to bigger premises with proper warehousing facilities in Ampang, Kuala Lumpur, in just over 3 months after its establishment. By 1971, extensive renovations were carried out to accommodate rapid growth and the subsequent increase in employees.

In 1972, the company’s name was changed to 3M Malaysia Sdn. Bhd. to reflect its international image. In the same year, 3M Malaysia was awarded three 3M International recognition for achieving outstanding performance.

Despite rising levels of competition over the years, the company has continued to undergo rapid expansion. 3M Malaysia’ expeditious growth is undoubtedly attributable to it commitment in satisfying its customers’ need through a wide range of innovative and quality products. 3M’s product diversity and technological expertise have helped it gain a reputation as a total solutions provider.

3M Malaysia’s superior understanding of its market environment has enabled it to deliver unparalleled quality, value and service. This understanding is the foundation that allows 3M Malaysia to maintain high customer loyalty and sustain its outstanding record of achievements.

HANNA HI 98107 pHep® pH Tester

HANNA HI 98107  pHep® pH Tester

HI 98107

  • Renewable junction
  • Easy 1 or two points manual calibration
  • 700 hour battery life
  • Simple to use
  • Economical

 

The pHep® revolutionized the pH industry by providing non-technical personnel with a simple, inexpensive solution to accurate pH measurement.

HI 98107 is used by millions of people around the world to monitor pH in laboratories and industrial applications as well as in agriculture, fish farming, food manufacturing and quality control, swimming pools and the printing industry.

With a renewable cloth junction, the pHep® has an extended life over typical pH testers. A normal junction clogs with use over time and a typical tester would normally have to be thrown away once the junction is too contaminated. HI 98107’s junction is 2 cm long and when dirty, can be pulled out to expose a fresh section to effectively renew the pHep’s life.

Calibration is performed manually at 1 or two points with a trimmer located on the side of the tester.

With a battery life of 700 hours of continuous use, the pHep® will provide years of testing before the batteries need to be replaced.

 

 

Order Information:
HI 98107 (pHep®) is supplied with protective cap, calibration screwdriver, batteries and instructions.
