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

My dogs are heavy chewers
These are very hard and indestructible. The only thing, im afraid my pups will break their teeth. They are houses on a hard wood floor.

My couch is safe!
Perfect for my lab mix, and my pointer mix was jealous so I immediately bought a second after they both wanted it. Keeps them both busy for well over 30 minutes.

Great treat holder!
Our new favorite!! We’d been long time long users but this will forever replace them. Sturdy, easy to clean, convenient cups, multiple fun treat compartments. They are also bright enough to find in the yard if one “runs” out the house. And they are easy for the kids to hold. Must have for a Pitt bull family

She loves it
Color: Octopus
My dog loves this. I mixed plain yogurt and blueberries and froze the two cups. She went to town and it kept her busy for about 15 min. It’s easy to open compared to some of the other toys like this. Easy to clean too.
