| Overview | beef extract is a concentrated product of beef extract, containing 50% of soluble nitrogen-containing compounds, which can be used as microbial culture medium. |
| properties | beef extract is a fluid material at room temperature, but the viscosity is very high, not easy to separate, as the temperature increases, the viscosity decreases sharply and separation becomes easy. |
| Application | beef extract is one of the most widely used and most common bacterial basal medium, sometimes called ordinary medium. |
| preparation method | when beef extract is required for preparation of culture medium, glass rods are commonly used for weighing beef extract, weigh in a small beaker or a surface dish, dissolve it with hot water and pour it into the beaker, or put it on the weighing paper, weigh it directly into water, and separate the beef paste from the weighing paper after slightly heating, and take out the weighing paper from the beaker. However, due to the high viscosity of beef paste at room temperature and the difficulty of separation, it is difficult to pick a certain amount of beef paste on a small beaker, a surface dish or a weighing paper at one time by using an instrument such as a glass rod, it needs to be repeatedly picked for many times to obtain the weight that meets the requirements. In many cases, the weight of the final weighing has a large error with the actual weight. |
