UP 0.45uM PTFE 50/PKUniPrep Syringeless Filters are preassembled filtration devices for the filtration and storage of laboratory samples. These devices are quick and easy to use and feature a plunger, Filter, and vial in one unit. They replace syringe-coupled filtration devices with single, disposable units.UniPrep devices consist of two parts: a test tube and a Filter-plunger. The design incorporates a preFilter and a membrane into the tip of the plunger. When the Filter plunger is pressed through the liquid placed in the test tube, positive pressure forces the filtrate up into the reservoir of the Filter-plunger. UniPrep devices function in a similar way to the Mini-UniPrep. However, UniPrep does not contain a septum in the cap and can be used to Filter larger volumes (1 to 5 ml).Integral storage vial saves time and minimizes laboratory waste.Built-in glass fiber preFilter means even difficult samples are quick and easy to prepare.Choice of membranes for wide sample compatibility.

Something I never knew I needed, and now can’t live without!
Color: Black, Size: Large, Color: Black, Size: Large
Absolutely perfect, high quality organizer. I was constantly reaching under the kitchen cupboards for sponges and drain stoppers which then cluttered up the sink while letting them dry before putting away. I love the size and option to put the basket on the outside edge for more space. It holds everything I need. I especially like the stone underneath so I can place it anywhere and not have to worry about a drain spout. Keeps my sink and counters clean and organized and looks great in my kitchen.

Best kitchen caddy!
Color: Black, Size: Large
This is the best kitchen caddy. It works well on the edge of my sink. It's a little bigger than I thought. My measurements were off, not there's. I propped up one side and it works beautifully. It holds all the sponges, soap, and cleaning utensils needed to clean your dishes. Now my kitchen sink is clutter-free. It also looks great!
