Offered with multiple MWCOs and two membrane options:

Cellulose triacetate (CTA) features high hydrophilicity and very low non-specific binding.
Cast without a support that could bind filtered solutes, these membranes are ideal where high target molecule recovery from the filtrate is important.
Polyethersulfone (PES) membranes exhibit low fouling characteristics, exceptional flux and broad pH compatibility.
Have a uniform surface, devoid of hydrophobic or hydrophillic interactions, offering excellent protein recoveries for most solutions.
Typical applications for Vivaspin™ Filtrate include:
Sample preparation for free drug
Metabolite or hormone analyses
Sample deproteinization
Separation of proteins from low molecular weight substances in biological samples
Sample capacity of 0.5 to 2.5 mL
May be used in fixed angle or swing bucket rotors, accepting standard conical or flat bottom 15 mL centrifuge tubes
Typically filter 90% of the initial sample volume in 30 minutes
Avoid premature membrane blockage by particle loaded samples
Retrieve the ultrafiltrate immediately after centrifugation without any disassembly

License flap is terrible, but wallet is nice
Style: Bi-fold
I do like the wallet but I hate the little extra flap inside it. It's very hard to get my license out of it. It makes the wallet way too thick. I just took it out and i don't use it. They should of just sewn 1 flap in there and the wallet would of been much thinner and still able to use the extra flap.

I love it
Color: Black/Silver
I need a watch has analog display (easy for me to read) and digital function (need the alarm and the countdown) also shows the day-date (the day has to be 3 digits e.g. Sunday is "sun" instead of "su"). I know I am very demanding, but it is just me, LOL. Have bought this watch for a couple of days. Yes, it fits all my needs. Pro: 1) Light weight, fair value materials, price is low and quality is fair. The glass is just a piece of plastic which is how I felt, but I put a packing clear tape on it and cut the edge off as my home made scratch protection. 2) There are 4 push buttons, except the center one for light, the other 3 seemed like are metal with rough surface which generate enough friction to hold and push it down. 3) It has Telememo, World Time, Snooze, two daily alarms, Count Down, hourly signal, and Stop watch functions. 4) 10 years battery which is better than solar battery (if solar battery never die), or it will be more expensive to replace a solar. 5) Casio always uses 4 screws to secure the back plate, much easier to replace the battery than other brands. 6) It has a smaller case (44 mm) with a larger LED display. Neutral: 1) Telememo, I don't know who needs this, because smart phones can do much more. Also, I try not to buy a watch with Waveceptor, smart phone can always pick up the correct time right after the airplane touch down. However, Waveceptor can auto reset the watch, but the problem is if it can receive the signal? and for how long? I still prefer the old school way to manually adjust. Con: 1) There is no pull out button to set up the analog, and this watch can only go forward. For example, if analog is 2 min faster, then I have to forward the hand for 11 hours and 58 min to correct it, that is a lot of pain, even you can hold both C & D to have the hand auto advance. Or, it only need to go backward for 2 min. 2) It can show two time zones time, but the digital day-date only matches with the digital time. One can not set the day-date to match with the analog. Overall, I love this watch, and there is a metal version "AMW830D-2AV".
