The CellTram® 4r Air and CellTram® 4r Oil are manual microinjectors suitable for a broad range of life science applications. The CellTram® 4r Air is a pneumatic injector for oil-free micromanipulation and gentle holding of cells in suspension. Due to its excellent performance, it is also highly suitable for uptake and injection of cells (e.g., of sperm or ES cells). For this application, its performance is comparable to that of oil-filled injectors. The CellTram 4r Oil is a hydraulic, oil-filled microinjector that provides more direct sample control and can generate higher pressures than an air system. It is optimised for leakage-free work and easy oil filling. Both models can be used with all common micromanipulation systems yet they develop their full potential with Agar Scientific manipulators. The CellTram® 4r Air/Oil injectors are for research use only.

Applications:

• ICSI of mouse and large mammals (e.g., equine, porcine...)
• Holding of sensitive oocytes, embryos or small organisms
• Piezo-assisted micromanipulation in combination with the PiezoXpert®
• Transfer of cells or organelles (e.g., ES cell or iPS cell transfer into blastocysts or morulae)
• Enucleation/nuclear transfer
• (Xeno)transplantations
• Removal of cells (e.g., for polar body biopsy, blastomere biopsy or trophectoderm biopsy)
• Manual microinjection and dispensing of aqueous solutions
• Single cell picking
