Microbial culture program for IKA constant temperature shaker--KS 4000 ic

<

In the process of transforming and cultivating various microorganisms, it is often necessary to use a constant temperature shaker for microbial culture, and then carry out amplification production. For different types of microorganisms, the oxygen demand and the optimal culture temperature are different during the cultivation.



What are the precautions for using a constant temperature shaker for culture?

  1. For microorganisms with large oxygen demand and fast metabolism, it is necessary to appropriately increase the rotation speed to make the oxygen dissolve more fully, and to mix the microorganisms with the culture solution to prevent the excessive growth of the metabolites to inhibit the growth of microorganisms.
  2. The higher the rotation speed, the better. Some cultures cause foaming due to the medium and metabolites. At this time, the rotation speed should be lowered.
  3. In some cases, it is necessary to protect the hyphae, or the bacteria are in a sensitive state, and it is necessary to maintain stable operation at a low rotational speed.
  4. For some temperature sensitive conditions, when the culture temperature needs to be strictly controlled, connect an external temperature probe for more accurate temperature control.
  5. Finally, since each culture is inoculated with different amounts of inoculum, medium ratio, and strain quality, the time to reach the logarithmic phase will also vary. A shaker with a transparent lid should be selected to observe the culture state in the flask in real time. .

Benefiting from IKA's many years of temperature control technology and stable motor motors, the KS 4000 ic can provide you with stable and reliable culture conditions:

  • Powerful and stable motor with a range of 10-500 rpm, reliable at low speeds
  • The motor has less heat dissipation and the low temperature constant is not affected.
  • Standard external temperature probe for more accurate temperature control
  • Transparent cover for easy observation of culture status in real time
