The CellTram 4r Air is a manual microinjector 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 model can be used with all common micromanipulation systems yet it develops its full potential with Calibre Scientific manipulators. The CellTram 4r Air injector is for research use only.
Applications
CSI of mouse and large mammals (e.g., equine, porcine...)
Holding of sensitive oocytes, embryos or small organisms
Piezo-assisted micromanipulation in combination with the Calibre Scientific 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
Features
Non-hydraulic system for oil-free manipulation and injection of cells
Piston position scale enables setting of air volume and injection characteristics according to individual needs
Coarse and fine drive for precise and intuitive sample control
Improved rotary knob design for better handling and easier cleaning
Capillary holder 4 with markings for easier positioning
New grip head 4 system for simple capillary change and higher user safety
Position indicators and marking for in/out to reduce risk of user errors
Stable, nonslip base plate
Highly reliable performance with minimal maintenance
Oil-free system with optimized resolution for holding larger cells in suspension and injection of cells (e.g., sperm)
Simple setting of operating point via pressure compensation
Extremely simple operation because no oil filling is required
Two rotary knobs of different transmission ratio (1:1 and 1:10) for the highest standards in terms of resolution, sensitivity and response behaviour
Compatible with most commonly used micromanipulators
