Certified Containers

Waters Certified Containers are uniquely processed, treated, and certified in the same unique manner as our highly regarded low TOC vials. These ultra-clean containers can be used on any LC system, including UPLC®, LC/UV, and LC/MS, among others. Manufactured to stringent standards, they prevent extraneous peaks and baseline noise stemming from high TOC. To help assist with contamination prevention and facilitate recommended care and use, each container carries the Waters certified mark for easy differentiation in operational use.

Features:

  • Suitable for a variety of instrumentation
  • Manufactured for stability
  • Packaged for convenience

Laboratory Filters

A Broad line of Filtration Products

Waters carries a broad line of Pall Life Sciences laboratory filters for sample and solvent filtration including:

Features:

  • HPLC sample filters in syringe filter format
  • Solvent filters in membrane disc format
  • Solvent filtration apparatus

The line includes a wide selection of membrane types and pore sizes to deliver the right lab filter for any sample type. A broad range of device sizes ensures complete sample filtration with minimal sample loss. The filter selector makes it easy to select the right lab filter for any application. See the lab filter selector demo on the right side of this page.


Filter Design

Pall Life Sciences broad range of device sizes assures complete sample filtration with minimal sample loss. In addition, many Acrodisc® syringe filters offer the option of a minispike outlet, rather than the traditional male luer outlet. The minispike outlet, available on 13 mm PTFE, Nylon, GH Polypro and PVDF Acrodisc® syringe filters, allows for easy dispensing into autosampler vials.


Membrane Design

Membrane Type (PTFE, GHP, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see chart opposite). For aqueous samples, it is preferable to use a hydrophilic membrane (GHP, PVDF or Nylon) versus a hydrophobic membrane (PTFE). With proteinaceous samples, a low protein binding filter (GHP or PVDF) is preferable to other hydrophilic filters (Nylon).
