Ahlstrom-Munksjö’s qualitative grades of filter paper are recommended for use in analytical methods which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance. These filter papers covers a wide range of laboratory applications, as liquids clarification, qualitative analytical separations for precipitates and buffers filtration, and are also used for soil analysis and in food and beverage testing. Standard qualitative filter papers are suitable for quadrant folded or gravity flow applications.

Supplier: GA

Supplier: MERKLINGER PRAZISION WERKZEUG

This column-packing technology is based on a combination of vacuum suction with subsequent column bed compression that stabilises the packing. A common water-jet pump is used to generate the vacuum. The sorbent slurry is sucked through a packing reservoir into the column by applying low pressure at the bottom end of the column.

Supplier: NICKEL ELECTRO

General purpose stirred water baths offering good temperature stability and uniformity for consistent, repeatable results. Operation below ambient is possible using an optional refrigerated dip cooler.

Supplier: Hach

Tests for all water analysis applications. The cuvette is a closed sytem which is safe for the user and the environment. Suitable for the laboratory robot.

Supplier: Restek

These Viva columns are based on a wide pore material designed for optimal large-molecule separations. Base-deactivated spherical silica is useful for normal-phase or HILIC separations. These columns have a narrow distribution around the mean pore size, permitting a larger portion of the silica surface to play a role in the separation.

Supplier: Restek

Viva C8 columns are conventional monomeric octylsilane columns offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase.

A wide choice of tests is available, for routine quantitative analysis in different applications, designed for use with WTW spectrophotometers and photometers. The test is automatically recognised by the laboratory instruments (via a barcoding system) and results are displayed in the appropriate units. Due to the different photometer optics, one test may yield different measuring ranges in different instruments; LED photometers may have smaller measuring ranges for the same test.
