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.

Nice to have a wider shoe! Nice color and seems to be good quality so far!
The fit ran a little bit small compared to Nike brand. Size chart at a shoe store I felt he needed a 1.5 (with room to grow still), ended up ordering a 2.5 which may have been a tiny big but works for his feet to grow. Love that it's wider. Cute color

Cute, durable kids' shoe at a great value
Size: 11.5 Big Kid, Color: Navy/Citron
These worked out great for our 5 year old with flat feet - he absolutely loves them, says they are very comfortable and help him "run FAST!" The colors look super cute, I'm very pleased with the durability over several months (particularly, the hook & loop closure has held up better than other brands we've tried...), and they seem to offer great support while not being too heavy. Highly recommend, and will buy again.

Durable Shoes
Size: 3.5 Little Kid, Color: Blue/Black
Most brands have scuffed toe pads or poor quality Velcro. My boys go through 3-4 pairs of shoes a year. Our family loves saucony for the quality, comfort and durability.

Great shoes
Great shoes, but definitely designed for narrow feet! if your child has wide feet,i recommend choosing a different style as these run very, very narrow.

Great colors!! Love the soles are not white. Good price
Size: 10.5 Big Kid, Color: Navy/Citron
Held up better than expected. So far only keens had held up to my son's play. Update-- after 2 months of wear the sole began to peel off/separate at the front of toe of shoe where that " upwards tab" is located.
