The Polydisc AS (Aqueous Solution) family of 50mm filter devices feature a high throughput polyethersulfone membrane, which has low protein binding and no surfactants, developed for use in the pharmaceutical industry. A glass microfiber prefilter extends the life of the membrane and effectively filters heavily contaminated samples. Each Polydisc AS device has a sterility cap on the outlet and is sealed in its own "medical grade" clear blister pack, irradiation sterilized, and secured in a protective shelf pack.
The Polydisc HD 50mm filters all polypropylene unit for aqueous and solvent samples with broad solvent compatibility. Excellent flow rate characteristics and highly suitable for filtering large volumes to 1 l of aqueous and solvent samples. Polydisc HD (Heavy Duty) is available in 5.0 and 10.0µm retention ratings.
The Polydisc SPF 50mm filters contain a stack of filter media ideal for prefiltration of serum and other hard-to-filter solutions. Contains a glass microfiber and polyethersulfone membrane filter stack that effectively filters the complex particulates found in serum samples.
The
Polydisc TF device features a PTFE membrane, which is ideal for chemically aggressive solutions, reagents, and organic solvents. This lightweight unit is particularly suitable for protective vents and for in-line filtration and isolation applications. The 1µm device features a polypropylene prefilter for use with heavily contaminated samples.
- Solvent-resistant membrane.
- Chemical-resistant housing.
- Hydrophobic PTFE membrane.
- Autoclavable (multiple times).
- Integrity-testable (bubble point or water breakthrough pressure in situ methods).
- Biosafe.
- Lightweight: Avoids the collapsing of tubing that can be caused by heavy filter devices.
The Polydisc GW (Ground Water) filters are specifically designed for sample preparation of ground water samples for the analysis of dissolved heavy metals. It is an aqueous filter with low background values for the determination of trace elements (each box contains a certificate).
It has everything that makes the preparation of aqueous solutions for the analysis of dissolved heavy metals easy: a large filter surface, quartz fiber prefilter and membrane filter in sandwich arrangement, and a high dirt loading capacity. And, of course, it meets all the requirements of regulations such as NEN and EPA.
