Mini-UniPrep Syringeless Filters provide a faster and easier way to remove Particulates from samples being prepared for High Performance Liquid Chromatography (HPLC)/Ultra High Performance Liquid Chromatography (UHPLC) analysis. In fact, Mini-UniPrep lets you prepare samples in one-third the time required by other methods. Add up the time savings, plus the money saved from cutting multiple consumables out of the sample preparation process and you'll see huge benefits for your laboratory.Mini-UniPrep is a preassembled filtration device consisting of a .4 ml capacity chamber and a plunger. The plunger contains a filtration membrane at one end and a preattached cap/septum at the other. The plunger is pressed through the sample in the outer chamber and positive pressure forces the filtrate into the reservoir of the plunger. Air escapes through the vent hole until the locking ring is engaged, providing an air-tight seal. Within seconds the Mini-Uniprep can be placed into any approved autosampler for injection into your instrument. The device can be used either manually or with a compressor unit. The multi-compressor can process up to 6 samples at one time, further improving sample processing time and reducing the risk of hand stress. The Mini-UniPrep device is designed to fit into any autosampler accommodating 12 x 32 mm vials. alternatively, the septum can be pierced with a needle and the sample drawn off for manual injection into an analyzer.

Extremely hard and durable
Color: Blue
These are very hard , but my puppy lives them and my large dog can't tear them up, so that is a huge plus.

Large breed approved
Color: Blue
these incredible aggressive chew toys – they've seriously been a game-changer for my pups! I know it's a bit late, but better late than never, right? I've got a couple of power chewers at home, a Rottweiler and a Labrador, and anyone with big dogs knows the struggle of finding toys that actually last. These bad boys have been in constant rotation for over a year now, and I'm genuinely impressed by their resilience. They're incredibly tough! Funnily enough, we originally had three, but now we're down to just one. The others aren't broken, though – I'm pretty sure my dogs just loved them so much they've hidden them away in some secret stash, as they tend to do with their favorite treasures! Beyond just being durable, these toys have been a massive help with their training. They’re fantastic for redirecting all that enthusiastic chewing away from my furniture and shoes, which, let's be honest, is a huge win for any pet parent! Considering how long they've held up to some serious chomping, the price point is absolutely spot on. You definitely get great value for your money.watch your toe they are heavy. If you've got a dog that's a champion chewer, you absolutely need to try these out. They're a lifesaver!

Durable chew toy.
Color: Blue
My dog loves these. She chews on them a lot. She seems to like the different shapes. She is part Pit and an aggressive chewer. These chew toys last a long time. And I love the three pack so if we lose one, we always have a spare.

Decent durability for the price
Color: Blue
Bought a bunch of these for a dog shelter and have to say - decent for the price of you have aggressive chewers. All of the toys are still going 6+ months later, even with the strongest jawed pitty mix. Does get torn up at the ends but can easily be sanded down for a longer lasting toy, unlike some other hard toys with material not meant for sanding. The antler and ring seem to be favorites. The antler even has a divot so you can put soft treats in it or peanut butter and freeze it for a more interactive experience. Some came with a strong beef/liver smell but not overwhelming or off-putting. They are hefty without being too heavy, less likely to damage floors. Overall a good purchase
