Frozen Semen Straw Cutter for 0.25/0.5ml Straws

The Frozen Semen Straw Cutter is a compact artificial insemination tool designed for accurately opening 0.25 ml and 0.5 ml frozen semen straws before loading them into an AI gun. Dedicated positioning holes help locate the straw automatically and produce a consistent cut with minimal deformation.

Model BTS-N44 combines a durable ABS housing with a stainless steel cutting component and concealed blade design. Its small handheld structure, wrist strap and replaceable blade make it convenient for cattle breeding farms, AI technicians and veterinary reproduction programs.

• Dual Straw Compatibility: Dedicated cutting positions for both 0.25 ml and 0.5 ml frozen semen straws.
• Automatic Positioning: Guided openings help position the straw correctly before cutting.
• Clean Cutting Edge: Controlled cutting action helps produce a smooth opening with less crushing or deformation.
• Hidden Blade Design: The cutting blade remains enclosed inside the housing for safer handling and storage.
• Replaceable Blade: Spare blade design allows replacement when cutting performance decreases.
• ABS and Stainless Steel Construction: Lightweight housing combined with a durable metal cutting component.
• Compact Handheld Size: Approximately 7.2 × 5.3 cm for easy carrying in an AI tool kit.
• Wrist Strap: Convenient strap helps reduce accidental dropping during field breeding work.
• Simple One-Hand Operation: Suitable for routine cattle artificial insemination preparation.

After the semen straw has been thawed and prepared according to the applicable AI protocol, the sealed end is inserted into the positioning opening corresponding to its 0.25 ml or 0.5 ml size.

Pressing the cutter activates the concealed blade, which cuts through the straw at the guided position. The prepared straw can then be loaded into a compatible insemination gun and sheath for the artificial insemination procedure.

Q: What is a frozen semen straw cutter used for?
It is used to cut the sealed end of a frozen semen straw before the straw is loaded into an artificial insemination gun.

Q: Which straw sizes can this cutter handle?
The BTS-N44 has separate positioning openings for both 0.25 ml and 0.5 ml semen straws.

Q: What material is the cutter made from?
The main housing is made from ABS plastic, while the cutting component uses stainless steel.

Q: What is the size of the cutter?
The current product specification is approximately 7.2 × 5.3 cm.

Q: Why use a dedicated straw cutter instead of ordinary scissors?
The positioning openings and guided blade are designed to provide a more consistent cut while reducing crushing or deformation of the plastic straw.

Q: Is the blade exposed during normal use?
No. The blade is concealed inside the housing, helping improve handling safety and protect the cutting edge during storage.

Q: Can the blade be replaced?
Yes. The design allows the cutting blade to be replaced when required, and the product is supplied with provision for a spare blade.

Q: Is it suitable for professional cattle AI programs?
Yes. Its dual-size compatibility, compact design and dedicated straw-positioning system make it suitable for dairy farms, breeding stations and professional artificial insemination technicians.
