SiLibeads® Glass Beads
SiLibeads® Type P PHARMA
Our SiLibeads® Type P PHARMA glass beads for medical and pharmaceutical applications, especially bead beating, cell disruption and mixing insulin suspensions as primary packaging material.
Glass beads made of soda lime and borosilicate glass
SiLibeads® Type P PHARMA are made from high-quality soda lime or borosilicate glass and offer maximum precision thanks to a special grinding process. With a diameter and roundness tolerance of < 10 microns on request and a manufacturing process that allows all special dimensions between 1.5 and 6.0 mm, SiLibeads® Type P PHARMA glass beads are available in various surface finishes, from high gloss to matt. Thanks to their high chemical resistance, they are ideal for use in aggressive and corrosive media.

Details
Applications
- Bead beating: Efficient cell disruption for biological samples.
- Cell disruption: Effective preparation of microorganisms, biofilms, plant samples or animal tissues.
- Vaccine production: High precision and purity for pharmaceutical applications.
- Mixing substances: Uniform mixing of pharmaceutical and chemical substances.
- Mixing insulin suspensions: Homogeneous mixing in insulin cartridges to ensure consistent dosing.
- Sample homogenisation: Improving the consistency of samples in laboratory analysis.
- Mixing bead: The pharmaceutical industry is a major area of application for mixing beads. To achieve a uniform mixture of insulin, insulin cartridges contain a borosilicate glass bead that mixes the contents when shaken.
Quality characteristics
- Precise and freely selectable diameters: Size range from 0.5 to 6.0 mm.
- Low diameter tolerances: For both individual balls (dK ≤ 20 µm) and lots (dL ≤ 20 µm).
- High dimensional stability and roundness: tolerance of dMAX – dMIN ≤ 20 µm.
- Pure and very smooth surface: no adhesions or inclusions, high purity.
- No air bubbles: very low proportion of beads with air bubbles (dB ≥ 0.5 mm).
- RTS (Ready to Sterilise): Ready for sterilisation, particularly suitable for pharmaceutical applications in sterile environments
- Highest purity of glass: Use of borosilicate glass type I in accordance with the Pharmacopoeia
- Highest safety of production processes: Manufacturing is ensured in accordance with GMP and complies with DIN EN IS0 15378
