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.

No angle for correct throwing
Size: 1-pack, Size: 1-pack
This item does not work. It is about ) inches tall. It’s tiny to bend over and pick up the ball. Has no angel for the ball to throw accurately. Ball goes downward. Would not recommend

Happy pup. Worth it.
My dog loves this thing. It takes hardly any effort to launch the ball. Flick of the wrist kinda thing. The squeaky ball is her favorite but unfortunately you can't buy this brand of ball separately. It says compatible with any 2.5 inch ball but that's not true. We have a ton of Penn tennis balls and they are just slightly too big for this launcher. You can do it but it's a huge pain and hard to throw. Another issue is that when we first got it the handle didn't want to stay screwed together. After the first day of use and having to rescrew it together multiple times, the issue seems to have corrected itself? Either way, for the price with the comfy handle, very low effort throwing for big pay off, two balls included and the crazy excitement from my dog anytime we get near the thing. It's definitely worth it. I like it much better than the chuck it and stone random cheap brand we used to have. I'm going to try one of the balls recommended in the product pictures. I'll update if they work out.

Ergonomic and well made.
I have at least a half dozen ball launchers and this is the nicest one. As efficient as any of them and it feels the nicest in my hand. As long as you tighten the handle when you put it together, it will serve your puppy well.
