Spiral Sinkers

Floating tablets rarely dissolve at a reproducible weight. Using a spiral sinker in Apparatus 2 fixes the tablet to a certain point and aids reproducibility. Spiral sinkers can also be useful where tablets may stick to the sides of the vessel.

All QLA Products are manufactured to ISO9001 quality standards.

Top Tips

Coated or Uncoated Sinkers?

Type 316 stainless steel sinkers are more durable than coated sinkers.

PTFE coated sinkers can be used where there may be a reaction between steel and the tablet.
