Why Our 30° Bevel is the Standard for ICSI ?

The Embryologist's Choice

In the delicate art of Intracytoplasmic Sperm Injection (ICSI), the success of the procedure often comes down to a single, critical moment: the puncture. This moment demands absolute control, precision, and a tool that feels like a natural extension of your hand. At Monash Biotech, we have engineered our Injection Micropipettes with this singular focus. While we offer a range of angles, our

30° angled pipette has consistently become the standard in laboratories for a clear reason: it perfectly balances ergonomic comfort with procedural efficacy.

The Science of the 30° Angle

The choice of a 30° angle is not arbitrary; it's based on the biomechanics of the ICSI procedure. This specific angle aligns with the natural resting position of the embryologist’s hand on the micromanipulator, reducing strain and allowing for more intuitive control.

Functionally, it facilitates a tangential approach to the oocyte. Instead of a direct, blunt puncture that can cause excessive membrane deformation, the 30° bevel allows the tip to "slice" through the oolemma cleanly. This controlled entry minimizes trauma, reduces the risk of lysis, and provides the tactile feedback necessary for a successful injection.

Precision Engineered for Your Technique

Understanding that every embryologist has a unique technique, we offer our 30° angled injection pipette with a range of specifications, allowing you to select the perfect tool for your needs.

• Inner Diameter (ID) Options: We offer multiple inner diameters for our 30° pipettes, including 5 µm, 7 µm, and 8 µm. This allows you to choose a finer pipette for standard procedures or a slightly larger one for cases involving sperm with larger heads.

• Spike vs. No Spike: Our ICSI micropipettes are available with and without a spike. The spiked tip provides a defined, sharp point for puncture, while the non-spiked version offers a smoother surface, catering to different procedural preferences.

• Consistent Bevel Length: The pipettes are engineered with consistent bevel lengths of 10 µm or 11 µm, ensuring predictable performance.

Every pipette we manufacture adheres to the highest quality standards. Each one is individually packed and sterile , with a measurement tolerance of ±5% and a consistent taper length of 600 µm.
