The new user-friendly TransferMan 4r combines unprecedented direct movement control with an ergonomic design to meet the most demanding micromanipulation requirements. Smart functions, such as improved automated home function and position storage, enable simple and precise execution of even the most complex micromanipulation techniques.

The unique DualSpeedTM joystick allows for precise and intuitive movement during injection in all three dimensions as well as dynamic movement for covering longer distances or speeding up sample processing.

The Transfer Man 4r is ideal for the manipulation of suspension cells such as oocytes, stem cells, microparticles and a wide variety of applications in reproductive biology. Application-specific user profiles simplify the individual workflow process with four pre-defined application masks to choose from (e.g. for cell transfer, DNA injection, etc). The freely programmable "My app" mask can be optimized for specific individual needs..


  • Micromanipulation of oocytes and early embryos
  • ES and iPS cell transfer
  • Nucleus transfer
  • Pronuclear and cytoplasmic injection (e.g., CRISPR/Cas, TALEN)
  • Selection of individual cells (e.g., biopsies, single cell picking)
  • Positioning and selection of microparticles
  • Microdissection of chromosomes, etc.
  • Microinjection into 3D organoids


  • Unique DualSpeed™ joystick for precise and instantaneous movement control
  • Maximum stability ensures vibration-free work
  • One Joystick for all 3 axes (X, Y, Z) movements and in axial direction (X/Z)
  • Angle adjustment from 0° to 90°
  • One-hand operation for capillary and angle settings
  • Programmable Z-axis limit for preventing capillary breakage
  • Connection with Eppendorf PiezoXpert¨ and electronic microinjectors
  • Can be adapted to all conventional microscopes
  • PC interface for remote control
