These cells are specifically designed for use in the µL range (down to 50 µL). These cells fit into any standard cell holder and have the advantage of requiring much smaller sample volumes than standard cells. The cells are constructed so that filling and emptying can be easily accomplished with commonly available pipette tips. Ultra-micro cells with Eppendorf pipette filling/emptying are designed to handle extremely small volumes. When only a minimum amount of sample is available, these cells provide a filling volume only slightly larger than the measuring chamber volume.
