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

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing. He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.
