Specific Overview
The VP 177P-1-200-40 is a 40 (8×5 array) mandril manifold that can pick up 200 ul LTS pipettes from a 40 (8×5 array) pipette tip rack. Springs hold the 40 mandril manifold up while a rack of 40 LTS pipettes slides in from the side and registers to the Manifold. Once in place, the Manifold is pressed down by applying hand pressure to the “press here“ spot on the Manifold. Thus, the mandrils are securely engaged in the LTS pipette tips.
The springs on the manifold move it up when the hand pressure is released, and the pipette tips rise out of the rack. The rack is removed and replaced with a 40-position rack with test tubes that must be sterilely aspirated. The liquid in the test tubes is aspirated by applying hand pressure to the “press here“ spot on the Manifold to lower the pipette tips into the test tubes and applying vacuum to the Manifold. The 3-stop adjustment bolts determine the bottom position of the pipettes. The adjustment on these bolts can be precisely determined for critical applications such as setting the distance above a pellet you do not want to be disturbed. If you are aspirating above a pellet, this system is for you.
To eject the pipette tips, slide a catch reservoir under the Manifold and then use both hands to press the ejection plate down, thus removing the used pipette tips into the catch reservoir. By changing the pipette tips each time between racks of test tubes, you can maintain the sterility of the sample left behind when multiple test tube racks must be processed.
