Stainless Steel Helix (Spiral) Sinker for Dissolution (SS316)

𝐐𝐂 𝐋𝐚𝐛 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧𝐬 𝐁𝐃 is offering QLab Accessories Stainless Steel Helix (Spiral) Sinker is a high-quality dissolution testing accessory manufactured from premium 316 Stainless Steel (SS316) to provide superior corrosion resistance, dimensional stability, and long-lasting performance in pharmaceutical laboratories.

Helix (Spiral) Sinkers are specifically designed to keep floating capsules and other dosage forms completely immersed in the dissolution medium throughout the testing process. Their open helical wire construction minimizes unnecessary contact with the dosage form while allowing unrestricted media flow, helping laboratories achieve accurate, consistent, and reproducible dissolution results.

The QLab Accessories Helix (Spiral) Sinker is available in multiple spiral configurations, including 4S, 5S, 6S etc. allowing laboratories to select the most appropriate sinker based on capsule size, dosage form, and dissolution method requirements.

• 4S Helix Sinker – Suitable for smaller capsules and dosage forms requiring minimal retention.
• 5S Helix Sinker – The most commonly used configuration for routine pharmaceutical dissolution testing.
• 6S Helix Sinker  and other– Recommended for larger capsules or dosage forms requiring additional support to remain fully submerged during testing.

Manufactured with precision and consistency, each sinker is designed to provide reliable performance while minimizing interference with dissolution testing.

As part of the QLab Accessories product line, every Helix (Spiral) Sinker is sourced from carefully selected manufacturing partners in India and China and undergoes our internal quality verification process before being supplied to customers, ensuring dependable quality for routine pharmaceutical laboratory applications.
