Description

PALL 4550 Acrodisc Syringe Filter with Nylon Membrane - 0.2µm, 13 mm, 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.

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:

It Works!
Size: 16 Ounce (Pack of 1), Style: SPF 50
My favorite sunscreen. Smells incredible. Reminds me of the beach every time I use it. Which is daily. Summers are brutal in the south and I don’t get paid enough for a farmers tan. Alba has saved me. I’m hooked on it. Also the price isn’t horrible either. Sunscreen can be so dang expensive. You get your moneys worth.

Defective item
Size: 16 Ounce (Pack of 1), Style: SPF 50
I requested a refund or replacement as one of the two bottles that arrived. Has an issue with spraying. When I put it in the unlocked position, it does not spray I requested from the seller, but the seller wants to meet to provide proof and requesting me to upload a video. When I explained the defect, they told me to move it to unlocked position. I buy this sunscreen all the time for my kids so I’m aware of how to lock and unlock a sunscreen Unfortunately through buyer/seller messaging you’re unable to leave a video so I will unfortunately have to leave a review here. I hope the seller will resolve this defective item.

Great after sun
This is one of the best aftersun lotions I've found. (And I grew up in FL so I've tried many!) I first discovered this lotion while on vacation on Sanibel Island - when I needed something to soothe my sun-kissed shoulders. It is super moisturizing, yet soaks in quickly. Isn't at all greasy, and leaves my skin feeling so nourished. I have even used it after getting burnt and have noticed considerably less peeling when I've used this immediately and consistently. IMO, the smell is a little strong - but it's a nice topical coconut smell - so not at all offensive. (I don't use a lot of scented stuff and therefore tend to be a little sensitive to smells - so keep that in consideration)
