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.

Arm can be positioned in many ways, but doesn't grip as hard and the phone rattles in rough roads
I liked how this product looked in the picture so I ordered it. But when I installed it, I found out that it doesn't have the same amount of "grip power" because you have to turn a little knob on the side to tighten the grip and it's not that easy to do compared to other screw type phone mounts that have bigger screws. The magnet was slightly weaker than my existing phone holder but it was adequately strong. It was good to see how one could position the phone in different positions due to the way the arm is designed to be moved and adjusted. But the one biggest thing I didn't like is how the phone kept on shaking/rattling when I drove over rough roads. The metal arm is quite thin and although it's metal and not plastic, due to the thinness of the material, it was easily rattled and made the phone rattle a lot in return. Over smooth roads this won't be a big problem though. I wasn't quite satisfied with this, although it's adequately good enough.

The search is over…
Style: 15W Charger
I have purchased so many mounts, but this one is perfect. It is easy to remove and apply to the screen. I don’t have to worry about damaging the screen with adhesive. The magnet is strong, and as a result, the phone is very stable. The most important benefit for me is the multiple viewing positions. The vertical placement and height are prefect. This is a quality product.

Reliable charging, surprisingly strong and securely holds my iPhone without needing any adhesive
Style: 15W Charger
The Qi2 15W Tesla MagSafe Charger is a great charging solution for my Model Y. I really appreciate the multiple mounting position options—it makes it easy to find the perfect setup. It also hides cords nicely, giving a clean, integrated look inside the car. The magnet is surprisingly strong and securely holds my iPhone without needing any adhesive, unlike other mounts I’ve tried. It delivers fast, reliable charging and works flawlessly with my MagSafe-compatible phone. Highly recommended for any Tesla owner looking for a clean and functional charging mount.

Cheap, easily breakable, and barley works
Style: 15W Charger, Style: 15W Charger
First off, it didn’t even come with the charging chord, so I had to order another separately after it came. The product broke the fourth time i used it, the whole thing came apart when i tried taking my phone off. When it was working, it charged maybe 1% every hour. Definitely not the best choice in the category, look at other options
