多功能组织材料生物力学特性、电位分布测试分析表征系统
EXPRESSION OR ASPIRATION FORCE
Syringes are tested to quantify the force necessary to activate the plunger and express or aspirate fluid from, or to, the barrel (break-away force, glide force, etc). These forces depend on factors such as materials used, viscosity of the liquid, sterilization technique, etc. Also, when the fluid is injected, the properties of the host tissue must be considered.
SAMPLE HOLDER, SYRINGE HOLDER KIT
MA085
This holder is designed to be compatible with syringes of various sizes. 3 pairs of perforated disks are provided to be placed on top of the holder allow switching between syringes of different sizes. A beaker is normally placed between the posts to contain the expulsed substance. A flexible tube can be attached between the tip of the syringe and the beaker of solution to minimize Archimedes' force. A special holder allows the syringe piston to be pushed or pulled by the vertical stage under the load cell to evaluate the performances of the assembly for a particular solution.

The present invention relates to magnesium phosphate hydrogels. More specifically, the present invention is concerned with such gels and their uses as scaffolds for bone tissue engineering, as drug delivery systems and in pastes for cleaning dental implants.
The force required to inject the NMP nanocrystals through an insulin needle of 160 ?m of internal diameter was measured using the instrument MachOne V500cs and MachOne Motion software version 4.3.1 (BMM Inc., Laval, Canada). The force was measured with a multiple-axis load cell of 70 N (resolution of 0.007 N) and acquisition rate of 100 Hz. The gel was loaded into the syringe avoiding the presence of bubble and then the plunger was inserted into the load cell. The force value was measured applying a constant vertical stage velocity of 1 mm s?1 (resolution of 0.1 ?m). The syringe loaded with deionized water required a force of 0.14±0.01 N, while for the NMP gels of formulation A-D were comprised in a range of 0.22±0.03 N and 0.77±0.04 N. At lower stage velocity (0.3 mm s?1) the required force to inject the NMP samples was considerably higher reaching a maximum of 18±1 N and a minimum of 9±1.2 N.
