GD/XP Syringe Filter, depth polypropylene, 0.45 µm, PP filtration medium, 6992-2504

Whatman GD/XP Syringe Filters – Prefilter

Cytiva's Whatman GD/XP disposable syringe filter, a modification of the GD/X line, uses a polypropylene prefilter stack, making GD/XP suitable for samples that require inorganic ion analysis.

- Incorporates a two-layer polypropylene prefilter stack rather than a multi-layer glass fiber stack to minimize levels of ion extractables

- Extremely low protein binding syringe filter

- High loading volume for filtration of challenging sample

- Recyclable after use. 

Disposable syringe filter for trace metal analysis

Because of their high purity and minimal ion extractables, GD/XP syringe filters are recommended for analyzing ion content that would otherwise experience interference from glass-based extractables. For example, GD/XP is used for trace metal analysis, particularly ion analysis using inductively coupled plasma-mass spectrometry (ICP-MS).

GD/XP syringe filter with integrated prefilter

The Whatman GD/XP disposable syringe filter from Cytiva's business has several different membrane material options. These include:

- Nylon

- Polyvinylidene difluoride (PVDF)

- Polytetrafluoroethylene (PTFE)

- Polypropylene – membrane or depth filter media

- Polyethersulfone (PES)
