The company manufactures a range of parts for use as components in a variety of medical devices.

Toxicological risk assessment of leachables from a syringe medical device

Case study

The company had commissioned leachables studies on a syringe medical device intended for flushing of intravenous catheters/tubing with saline. The leachables profile was examined at two time points (day 0 and about 2 months) and numerous substances were detected at low concentrations.

Making sense of skin sensitisation

Blog articles

From cosmetics to cleaning products, skin allergy (sensitisation) is a prominent feature of our modern chemical-centric world. Put simply, this hazard is an abnormal reaction of the immune system which makes certain individuals overly sensitive to particular chemicals. Read more in our blog, to help you make sense of sensitisation.
