With SpeediKit, sperm separation becomes simple. The medium is pre-filled in glass centrifuge tubes, so you can begin immediately, no preparation or manual layering required.
Why glass matters
The SpeediKit tubes are made of borosilicate glass, engineered for laboratory performance:
- Superior resistance to rapid temperature changes
- High chemical stability (resistant to acids and alkalis)
- Lower contamination risk
- Durable and scratch-resistent
- Excellent clarity for easy monitoring
Material considerations
In‑house research played a key role in selecting the optimal material. Among the pharmaceutical‑grade options, DIN Type I borosilicate glass was chosen over sodium silicate glass. Sodium silicate glass can release sodium ions over time, altering Na‑ion levels in stored media. In mouse embryo culture tests, these shifts were sufficient to impair embryo development, reducing progression to advanced blastocyst stages.
SpeediKit combines ready-to-use convenience with the proven safety of borosilicate glass, supporting consistent and reliable results, right from the start.
