Air Leakage During Aspiration – Catheter Hub Assembly
Catheters are connected to a partially filled syringe, a negative pressure is applied by pulling on the syringe plunger, visual inspection is performed to detect any bubbles forming in the syringe.
Catheter hubs assemblies are connected to the syringe to form a leak proof connection while sealing all valves that are intended to open during aspiration. A known volume of water is drawn into the syringe. While the syringe nozzle is pointing downward, the plunger is withdrawn to the maximum capacity, and held for a defined period of time. This is to verify that no bubbles are forming in the syringe, therefore testing the seals efficiencies.

ViVitro Labs Advantages
Many companies look to academia to handle their testing needs due to the reduced cost. With ViVitro Laboratory Services you gain the following advantages:
Test Method Validation
The FDA and Notified Bodies around the world are requiring evidence of Test Method Validation. ViVitro Labs has invested significant resources to validate the most common test methods that are not ISO 17025 accredited. We continue to work closely with device manufacturers and share the burden with our clients to validate other specific test methods that are less in demand.
We understand how critical your timelines are. Our expertise and experience ensure your schedule is met and our commitments are delivered on time.
Free Initial Consultations
All of our studies are scoped via no-cost, no obligation, collaborative consultation.
We happily provide Non-Disclosure Agreements for all services, including initial consultation.
