A hand-held lift loop assembly tester apparatus and method tests peel strength of a heat seal connection between a lift loop patch and a bulk bag body as an indicator of shear strength of the connection and whether the bag will pass industry safety lifting requirements. A lifting platform of the hand loop tester is inserted between the patch and the bag body in an unsealed area and measures the amount of peel and thus the peel strength of the heat seal bond or connection at the edges or sides of the unsealed area. If the peel strength is adequate, this is a reliable indicator that the shear strength of the bond or connection is also adequate and that the bag will meet the current industry required 5 to 1 safety lifting requirements.

The present approach relates to the design and use of a functionally closed bioreactor designed to immobilize, culture, and mature tissue on a loading platform. The bioreactor may be equipped with sensors for tissue monitoring which in conjunction with stiffness data can provide closed-loop control of tissue maturation. Based on a relationship between cartilage stiffness and tissue maturity, measurements of stiffness can be acquired and used as a surrogate for cartilage maturity without the need for destructive tests.

An optical measurement system comprising a vessel for non-invasively testing a sample material composition in-situ and in real time. The test chamber is configured to hold a sample material composition for a wellbore. The optical measurement system is configured to provide in-situ monitoring of the sample material composition in real time and at high temperature and high pressure. Dimensional and geometrical changes occurring within the sample material composition are monitored using the optical measurement system. The system further performs goniometry on a sample.
