45-0751 Microject 1000A Microinjection System BTX


Alternative method to deliver genes, proteins, macromolecules and micro-beads in direct injection into cells, tissues and oocytes simply and efficiently.



The MicroJect 1000A offers an alternative method to deliver genes, proteins, macromolecules and micro-beads by direct injection into cells, tissues and oocytes simply and efficiently. This microinjection system provides  consistent and precise delivery of volumes through digitally-controlled, stable pressure regulation maintained for a set duration of time. The compressed gas, internally-controlled pressure system also allows the precise delivery of desired volumes ranging from femtoliters to microliter volumes.

The MicroJect 1000A can hold a cell, oocyte or early stage embryo stationary while simultaneously using a separate pressure channel for injections. The system is versatile enough to provide the same consistent performance needed to inject large volumes into tissue such as capillaries, or pico volumes, for nuclear injections. It is also ideal for the gentle transfer of delicate fetal or stem cells into oocytes.


  • Key pressure features maximize injection potential with two negative and three positive pneumatic capabilities
    • Negative pressure feature allows you to fill micropipettes from their tips
    • “Fill” feature reduces waste.
    • “Hold” feature lets you immobilize and manipulate a cell or oocyte using a micropipette.
    • Positive pressure feature precisely discharges fluid by using the system’s “Clear” function
  • Unique “Balance” feature provides a secondary balance pressure to maintain positive pressure on the injection pipette, avoiding the chance of diluting sample due to capillary action.
  • Two footswitches included for easy operation of the Clear/Fill features.
