1. Do not wash with heavy alkaline solution, so as to avoid the weight loss caused by corrosion of glass and the leakage of stainless steel parts.
2. The injector should be dipped in the solution and pulled back and forth several times before use to expel bubbles from the needle tip. Otherwise, it will affect the correctness of the effect and the capacity progress. It should be cleaned immediately after use to prevent the needle tip from blocking or jamming.
3. If stainless steel oxide is found in the sampler, the phenomenon of "blackening" will affect the normal use, a small amount of soap can be dipped in the stainless steel core and put into the sampler several times to pull back and forth, and then clean.
4. The solubility indicator core of the microinjector without liquid storage should not be pulled more than the trademark if it is pulled out carelessly and can be reassembled. The needle-tip nut must be rotated first, then the core must be patiently passed through the silicone rubber washer, and then the nut should be rotated on the needle-tip hole to push the core, so that the stainless steel wire can not be bent directly.
5. The needle tip of the sampler should not be burned in order to avoid annealing of the needle tip and loss of puncture ability. If the needle tip is blocked, 0.1mm stainless steel wire should be used in collusion.
