Biomedical company benefits from ADMET’s testing machine
ADMET’s eXpert 8900 series determines durability of biomaterials
How materials testing meets international regulations for the medical device market
European lawmakers are considering new regulations for managing the development of medical devices and implants. This is due to the after-affects of several defective devices hitting the market. Materials testing is one important step for ensuring the safety of all heart stents, bone screws and other biomaterials. ADMET offers a multitude of testing machines for the biomedical market.

Medical Device Testing: Testing for the Evolution of Disposable Syringes
Plastic disposable syringes were first introduced in 1961. When the “Disposables Revolution” arrived, it greatly reduced the number of infections transferred between patients because syringes became single-use only. Medical operations also became more efficient as the sterilization process for reusable glass syringes was no longer required. The transition from glass to plastic syringes seemed like a no-brainer.
Instron BioCoat: Protecting You and Your Testing System from Liquids
Many medical devices and biomaterials are tested in a bath of water or saline heated to 37°C (body temperature) to simulate the environment in which they will be used—catheters, stents, and suture materials are a few examples. Although this robust solution accurately replicates a biomedical environment, there is opportunity for spillage or leakage when using a bath of liquid. Spillage can sometimes occur when a bath is being used, filled, or emptied incorrectly.
Medical device testing: Internal fixation vs. external fixation
Both internal and external fixation devices assist in proper bone healing. Despite this similarity, differences exist between devices and this is reflected in how they are tested.
ADMET testing machines are capable of multiple methods of testing fixation devices. This includes simultaneous Torsion and Tension testing and Torsion testing with a pulley counter balance weight. Read more.
MIT researchers working to develop biomimetic medical adhesive
Researchers at MIT, led by Professor Jeffrey Karp, are looking into the remarkable adhesive properties of Gecko feet in an effort to develop better adhesives for biomedical applications. They’re using an ADMET eXpert 7601 Universal Testing Machine to aid them in better understanding the forces at work.
ADMET’s BioTense bioreactor used in Northeastern University cornea research
Researchers at Northeastern University are studying the effects of mechanical strain on cells to see if they can induce the cells to produce corneas for human transplant. An important aspect of their research is use of ADMET’s BioTense perfusion bioreactor, a state-of-the-art device that allows the team to apply strain while permitting simultaneous study via a microscope.
Pipette tips: Determining stiffness with a bend test
How does discovering the mechanical properties of a product help determine the process for manufacturing? An ADMET Customer presented us with a problem. Their plastic disposable pipette tips lacked sufficient stiffness to ensure the customer’s success in dispensing fluids.
