Benchtop Gene Gun
GJ-1000 High Pressure Gene Gun
The GJ-1000 is a bench-top, gas-driven biolistic particle delivery system (gene gun) for laboratory-scale gene transfer. A rupturable membrane, made of polyimide film in different thicknesses, regulates the helium pressure inside the chamber. When the pressure reaches the membrane’s critical point, it bursts and releases a powerful shock wave that drives the particle carrier downward at high speed to bombard the target cells, tissues or organs. Working pressure is adjustable between 3 and 12 MPa, allowing the system to be optimised for a wide range of sample types.
Features
- High conversion rate – biologically inert particle carriers improve safety and precision
- High versatility – gas-driven design simplifies operation and widens the range of applications
- Optional carrier membranes – flying or steel membranes available depending on the receptor
- Adjustable pressure – optimised between 3–12 MPa for different sample types
- Quick cleaning – detachable circular chamber allows easy sterilisation
