0.25 ml (Minitube)


For over 25 years, the Minitube 0.25 ml and 0.5 ml semen straws have been used worldwide as a standard for the freezing of semen from bulls, stallions, boars, and many other species. Minitube’s quality control process, production techniques, and material selection ensure for a reliable product that consistently exceeds industry standards.

EcoStraws are used in exactly the same way as standard semen straws:

  • identical processes for filling,
  • identical processes for sealing,
  • identical processes for printing,
  • identical processes for insemination.

EcoStraws feature a plug with a shorter inner wick section that absorbs 3 - 4 % fewer sperm cells than the corresponding symmetrical plugs of standard semen straws. They are ideal for overnight equilibration of semen at refrigerated temperatures.

EcoStraw Benefits

  • Better utilization of available sperm cells per ejaculate because fewer sperm cells are lost in the plug
  • Yield a larger number of semen straws per ejaculate
  • Better use of valuable genetics without adding additional costs
  • Ideal for overnight equilibration and fresh semen preservation
