Alright lab people, researchers, and science folks - if you go through transfer pipettes like crazy, this Karter Scientific 400-pack is exactly what you need! These are the non-sterile LDPE (low-density polyethylene) pipettes that are workhorses in any lab setting. With an 8.7ml total capacity and a bulb draw of 4.8ml, they're perfect for all sorts of liquid handling tasks. The fine tip is 1.4mm in diameter with a 6.1mm stem, giving you good control for precise transfers. They deliver about 45 drops per milliliter, which is pretty standard for this type of pipette. What's really handy is how they're packaged in those hinged dispenser boxes that make grabbing one quick and easy without contaminating the others. The LDPE material is non-toxic and chemically inert, so it works with biological fluids and most acids without reacting. They can handle temperatures from -50°C to 90°C, and you can even heat-seal them and freeze samples in liquid nitrogen if needed. At 147mm length, they're comfortable to hold and use for extended periods. Whether you're in education, research, quality control, or industrial applications, having a bulk supply of reliable pipettes just makes life easier. The quality is consistent pipette to pipette, with smooth bulb action and clean tip formation. For the price per pipette, it's way more economical than buying small packs, and the quality is definitely better than some of the cheaper alternatives out there. They're perfect for general lab work, classroom use, art projects, or any situation where you need to move small liquid volumes accurately and efficiently.
