Description

PALL 4541 Acrodisc Syringe Filters with Nylon Membrane - 0.45 µm, 13mm, male slip luer outlet (1000/pkg)Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build up and reduce system downtime. Sample filtration using syringe filters containing 0. 45 m (HPLC) or 0. 2 m (UHPLC) pore size membranes will also extend the life of chromatography columns

Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build-up and reduce system downtime. Sample filtration using syringe filters containing 0.45 μm (HPLC) or 0.2 μm (UHPLC) pore size membranes will also extend the life of chromatography columns by preventing particulate from blocking the flow path between the column packing.
Nylon syringe filters can be used for both aqueous and solvent-based sample filtration applications and show excellent chemical compatibility with esters, bases and alcohols. However, it should be noted that nylon syringe filters are not recommended for sample fluids which are strongly acidic.
13 mm Acrodisc syringe filters are designed for the filtration of sample volumes up to 10 mL. They feature an effective filtration area of 1.0 cm2 and a polypropylene housing which has excellent chemical compatibility properties. The syringe filters are HPLC certified for low levels of UV-absorbing extractables, preventing spurious peaks on chromatograms, ensuring both accurate and reliable results.
Pall 13 mm Acrodisc syringe filters are available with a standard male slip luer outlet or Pall’s proprietary minispike outlet. The minispike allows for easy handling with a HPLC vial, and offers a reduced hold-up volume, ensuring maximum filtrate recovery.
Typical hold-up volumes:
13 mm, male slip luer outlet:

An excellent replacement for the old camper watch
Color: Black/Black/Black
I wore Timex camer watches for much of my adult life. I prefer the analog wind-up versions, but they are not widely available at a reasonable price. I purchased this model for its large easy to read face and durable strap. The Indiglo feature is a bonus.

Favorite watch / solar
Color: Green/Green
I'm partial... I have bought Timex my intire life, they no doubt make the best watches... They take a licking, but keep on ticking is there old commercials.. True.. Great quality, keeps going after many year's... I never bought a solar watch from them prior I have to mention... It should hold up I'm thinking like their battery watches, I hope so. My favorite watch, I own a handful. Watch looks better in person... Downfall, they are trying a new band out of recycled plastic, I don't like it as much as the older bands it's soft, but feels a little strange...

Solar powered
Color: Green/Green
Great watch for us older folks. The hands are large enough to see easily and the fact it is solar powered means batteries do not have to be replaced every year or two.

Nice watch
Color: Green/Green
Very happy with my purchase, rated the purchase with 4 stars due to the band being very stiff, holds doesn't line up to fit wrist properly, don't recommend for seniors to purchase, very difficult to put on.
