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.

Loooove these shoes!
Size: 7.5 Wide, Color: Chestnut Brown Faux Leather
I have these in several colors, and they’ve become a true staple in my wardrobe. The Amazon Essentials Women's Belice Comfortable Slip-On Ballet Flats are exactly what I look for in an everyday shoe—simple, versatile, and comfortable right out of the box. The slip-on design makes them super convenient for busy days, and they pair effortlessly with everything from jeans to dresses to work outfits. They’re lightweight but still feel supportive enough for all-day wear, and I appreciate that they don’t require a break-in period. The fit is generally true to size, and the variety of colors makes it easy to stock up and rotate depending on the outfit. Overall, these are reliable, easy-to-wear flats that offer great value for the price. Not flashy, just consistently comfortable and practical—which is exactly why I keep coming back to them.

REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
Size: 8, Color: Black Patent
I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.
