The CellTram® 4m Air and CellTram® 4m Oil are manual microinjectors specially designed for various ART-applications. The CellTram® 4m Air is a pneumatic injector for oil-free micromanipulation and gentle holding of oocytes and embryos. Due to its pressure performance, it is also highly suitable for uptake and injection of cells (e.g., sperm). For this application, its performance is comparable to that of oil-filled injectors. The CellTram® 4m Oil is a hydraulic, oil-filled microinjector optimised for precise control of high pressures, e.g. for biopsies, leakage-free work and easy oil filling.

Applications:

• Intracytoplasmic sperm injection (ICSI)
• Gentle holding of cells or embryos (e.g., oocytes or blastocysts)
• Uptake and microinjection of small cells (e.g., sperm)
• Transfer of suspension cells or organelles
• Removal of cells (e.g., for embryo biopsies)

Features:

• Non-hydraulic system for oil-free manipulation but also injection of cells (CellTram® 4m Air)
• Piston position scale enables setting of air volume and injection characteristics according to individual needs (CellTram® 4m Air)
• Improved oil-filling system for minimal interruption of the workflow (CellTram® 4m Oil)
• 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 and defined capillary position
• 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
• Heavy, stable, nonslip base plate
• Highly reliable performance with minimal maintenance
• Manual hydraulic microinjector
• With gears 1:1 and 1:10, for holding and injection, The CellTram® 4m Oil has been designed and manufactured to support the injection and aspiration of cells or cell components during the performance of assisted reproductive technologies (ART) such as intracytoplasmic sperm injection (ICSI), or the collection of genetic material for the purpose of genetic preimplantation testing (PGT), using micro tools (e.g., microcapillaries or micro glass pipettes)
