Description

PALL 4452 Acrodisc Syringe Filters with PVDF Membrane - 0.45 µm, 13mm, minispike outlet (100/pkg 300/cs)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.

PVDF syringe filters offer excellent chemical compatibility, including aggressive acids and alcohols. However, they are not recommended for the filtration of acetone, DMF, DMSO, or strong bases.

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:

Firm and comfortable
Item Package Quantity: 2, Size: Standard
These pillows are well made. Firm, yet comfortable. I am pretty rough with my pillows. I toss and turn frequently. After one year, they are still holding up.

Quite good. I am actually surprised. Too small for queensize
Item Package Quantity: 2, Size: Queen
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning. Update 04/24 These are actually quite small to be considered queen pillows. They have become firm over the last few days.

Full, Fluffy & Perfectly Supportive Euro Pillows!
Item Package Quantity: 2, Size: European, Item Package Quantity: 2, Size: European
These Euro size pillow inserts are fantastic! They’re soft, full, fluffy, and hold their shape very well. The firmness is perfect — supportive without feeling too hard. They filled my pillow covers beautifully and made the bed look much more luxurious. Great quality for the price and very comfortable for lounging or sleeping. Very happy with this purchase!

amazing.
Item Package Quantity: 4, Size: Queen
WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!
