Whatman 1PS Phase Separator

The Whatman 1PS Phase Separator is a high-grade filter paper impregnated with a stabilized silicone that renders it hydrophobic, retaining the aqueous phase and passing the solvent phase through.

Automatic Cut-Off, Separatory Funnel Replacement

After being shaken, the mixed phases are simply poured directly into the 1PS circle which is quadrant-folded in a funnel. The separation is extremely rapid so it is unnecessary to wait until the two phases have settled into separate layers. Droplets are automatically separated after only a few moments, giving a solvent phase completely free of the aqueous phase. In many applications, 1PS can replace the use of separatory funnels. The solvent phase flows through the paper quickly and cleanly. It then stops automatically, leaving the aqueous phase completely in the paper. This feature is particularly important when carrying out a large number of routine solvent extractions at the same time. Samples can be shaken with solvent in stoppered conical flasks or test tubes and transferred directly to funnels containing 1PS.


Unsupervised Separation

A chief benefit of the 1PS method is that cut-off is automatic and complete just as soon as the solvent phase has passed through*. The result is no skilled operators are required.
* Water may break through upon prolonged standing.

Features and Benefits
Ease of use - no special training required
Any number of separations can be processed together
Staff involvement in routine separations is at a minimum

Whatman過濾用紙 (Filter Papers)
纖維濾紙 (Cellulose Filters)
土壤分析用濾紙 (Soil Analysis FilterPaper)

Grade 0790

Acid-washed paper with ash content of approximately 0.01%, low-magnesium, for the determination of trace elements (Mg, Mn, Co, Cu, Mo, B)

Grade 512 Low-phosphate papers (approximately 1.5 ppm phosphate), for the filtration of calcium lactate extracts from soil samples for the determination of K and P according to Egnér, Riehm and Lederle
Grade 551 Black coloured paper with a medium to slow flow rate. Provides contrast for the detection of very fine traces of white precipitates. Grades SA 610, SA 620, SA 710, SA 720 and SA 730 Great wet strength, fast, low blank values for sensitive detection methods and optimized for USA soil analysis methods.

標準級定性濾紙 (Qualitative Filter Papers–Standard Grade)
Grade 1: 11µm The most widely used filter paper for routine applications with medium retention and flow rate. Extended range of sizes includes 10mm to 500mm diameter circles and 460mm x 570mm sheets. This filter is also available in the Whatman FilterCup™. This is a convenient, disposable 70mm filter funnel with a 250mL capacity moulded from polypropylene with an integral, heat bonded filter. 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 sulphate, 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 colour formation quantified by optical reflectance. Grade 2: 8µm Slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed). More absorbent than Grade 1. Also available in folded (prepleated) form as Grade 2V. In addition to general filtration in the 8µm 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.
Grade 3: 6µm 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 Whatman FilterCup. This is a convenient, disposable 70mm filter funnel with a 250mL capacity moulded from polypropylene with an integral, heat bonded filter. Grade 4: 20-25µm Extremely fast filtering with excellent retention of coarse particles and gelatinous precipitates such as ferric hydroxide and aluminium hydroxide. Very useful as a rapid filter for routine cleanup 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: 2.5µm 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. Grade 6: 3µm Twice as fast as Grade 5 with similar fine particle retention. Often specified for boiler water analysis applications.

濕潤加強級定性濾紙(Qualitative Filter Papers – Wet Strengthened Grade)
Grade 91: 10µm A general-purpose crêped filter for less critical routine analysis. Widely used to assay sucrose in cane sugar and within pharmaceutical laboratories for routine filtration. Grade 113: 30µm Ultra high loading capacity with a particle retention making it ideal for use with coarse or gelatinous precipitates. Fastest flow rate of the qualitative grades. Creped surface. Thickest filter paper in the Whatman range. This filter is also available in the Whatman FilterCup. This is a convenient, disposable 70mm filter funnel with a 250mL capacity moulded from polypropylene with an integral, heat bonded filter. Grade 114: 25µm Only half the thickness of Grade 113 and suitable for coarse or gelatinous precipitates. Smooth surface for easy recovery of precipitates.

教學級定性濾紙(Qualitative Filter Papers – Student Grade / Grade 93)
Designed for educational use, this filter paper is intermediate in speed and retention between Grades 1 and 4. Student grade retains those flocculent and medium precipitates most often encountered in student experiments. Available in a dispenser pack, it can be attached to the wall or bench, placed on a shelf either upright or flat, and used as a normal carton or as a convenient dispenser. The envelopes are released individually for easy one-at-a-time removal. Package and envelopes are clearly marked for size and content.
