This line of pipettor stations holds 1, 2, 3, 4 and 6 pipettes. Few labs limit themselves to one particular brand of pipette, yet each type often requires a different holder. These pipettor stations are designed to help eliminate this problem. These multi-purpose holders are clear, white, neon green and neon red and accommodate most brands of pipettors. These pipettor stations have a 1 in. upper rack and a ¾ in. lower rack.
