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.

Great Strong Chew Toy but not too Hard
Color: Red Pulse, Size: Medium
Great strong chew toy. It's very strong and does not tear apart like everything else. At the same time it is not hard plastic like the last brown one I ordered that could break my dog's teeth. My dog is a 2 yr old 14 lb Chi mix with a super strong bite. He tore all the stuffies up and even the nylon toy that was supposed to withstand a lot. This is the one toy that could outsmart him. I play fetch with him and it has a nice weird hop due it's shape so it keeps him interested and surprised. It's a bit heavier than other similar toys and I'm guessing bigger dogs would definitely like it too. I'm very pleased after buying so many others that were easily chewed up or too hard.

Unsafe and absolutely garbage
Color: Yellow Frisbee, Size: Large
If I could give this zero stars, I would. My dog had it for approximately two minutes of playtime, I didn’t even get to throw it, and it already had holes in it. He wasn’t chewing it or playing aggressively. He simply had it folded in half in his mouth and it tore. This toy is not safe for dogs.

Perfect ball for my Chihuahua
Color: Multi Meteor Ball, Size: Small
My dog is a Chihuahua. The small size is perfect for her. She loves chewing on the ball and loves the crackling noise from the material inside. I love that it is strong enough, she cannot tear it apart or is she able to remove the material inside. Perfect for her.

Best toy for our dogs!
Color: Yellow Frisbee, Size: Large
These are great for our labs. They love to fetch and play in the back yard. Loved how sturdy these have been the last few days. The material is tough enough to withstand our boys.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!
