Description

PALL 4555 Acrodisc Syringe Filters with PTFE Membrane - 0.45 µm, 13mm, minispike 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.

PTFE membrane is highly chemically compatible for the filtration of harsh solvents that can destroy other membrane materials. PTFE is a hydrophobic membrane, so it will repel water and is not suitable for the filtration of aqueous solutions.

As well as being suitable for the filtration of organic solvents in applications such as HPLC and UHPLC sample preparation, the hydrophobic nature of the PTFE membrane makes these syringe filters ideal to use in gas filtration or as a moisture barrier in venting applications.

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:

Glorious Wooden Palm Rest Durability and Stability in an Elegant Design
Color: Onyx, Size: Mouse Wrist Rest, Color: Onyx, Size: Mouse Wrist Rest
After years of using foam palm rests, I always encountered the same problem: they deformed over time, losing height, ergonomics and, consequently, their usefulness. This is especially critical when you spend between 3 and 8 hours a day at the PC for work, study or gaming, since a bad posture can increase the risk of suffering from carpal tunnel syndrome. This is where Glorious' wooden palm rests come in, a solution that eliminates deformations and offers an ideal height for both the mouse version and the TKL (Tenkeyless) version. Positive points • Solid and durable construction: Unlike foam, wood maintains its shape and provides stable support over time. • Elegant and minimalist design: Its finish gives a premium touch to any setup. • Effective non-slip base: The bottom rubbers prevent unwanted movements, providing total stability. • Easy maintenance: Although wood is slightly porous and can retain natural oils or residue from creams and perfumes, cleaning it is easy. Areas for improvement • Less softness than foam: Although still comfortable, wood sacrifices some of the cushioned feel that some prefer. A redesign with a foam strip on top could improve this. • Inconsistent finish between versions: I bought the mouse rest and the TKL at the same time, but noticed that the color tones were different (one blacker than the other). It doesn't affect functionality, but it does affect aesthetics. If you're looking for durability, stability, and a sophisticated design, this is a highly recommended palm rest, especially if you find it on sale. Although it's not as soft as the foam ones, it does its job of providing ergonomic support exceptionally well. An excellent complement for those who spend long hours at the PC and are looking for a sturdier alternative to traditional palm rests.

great mouse rest
Color: Golden Oak, Size: Mouse Wrist Rest
This works really well for for elevating your wrist, I use an apple trackpad it puts my wrist a little too high so what I did was put some rubber pads on the back of my trackpad to raise it up. It now gives the perfect height and good support I can even lean on it. It works well to the fact that it gives you very good support it's not uncomfortable and it's very easy to clean and looks very nice on my desk, because it's made out of real wood.

Great wrist rest. Smooth finish, good looks, and ideal wrist angle.
This wrist rest sets you up for pretty optimal, level height to prevent future wrist problems. I went with the nice reddish/brown color as it matches my brown wood Edifier speakers and other brown accessories very nicely. Nice matte finish that avoids showing finger prints and skin oils. The color is perfect, not too red or too brown. Keep in mind if your keyboard is angled in the front it will leave a bit of a gap, however it is unnoticeable to me. Also, make sure your arm rests of your chair can come high enough to meet the half inch or so thick wrist rest. My arm rests are a bit low for the time being so some extra pressure is put on my arm behind the wrist when resting on the chair supports.

Not for me
Color: Golden Oak, Size: Mouse Wrist Rest
It's tough to review something like this that functions perfectly, but just wasn't the right fit. The Glorious wrist rest for the keyboard is perfect and exactly what I wanted/needed, but the mouse rest caused hand and wrist pain. I swapped it out for a squishy alternative and that worked much better. I have a theory it might have been due to the relatively low height of my ektecity gaming mouse relative to the mouse rest. My keyboard is a higher height and that may be why the wood keyboard rest works so much better.
