The MTC Bio P4300-RK 300µL Pipette Tips, 10 Racks of 96 Tips (960 Total Tips), are designed to fit MTC's 300µL single channel pipettes. Many researchers have recognized the need for an accurate pipette for volumes above 200µL, which is a range that is not well served by traditional 1mL pipettes. The MTC Bio 300µL pipette (sold separately) and pipette tips close the gap and permit accurate and convenient pipetting, especially in the 200 to 300µL range. These tips also fit most popular 300µL multi-channel pipettes and are supplied pre-sterilized in 96 position racks.
