However, in order to save costs and introduce unnecessary troubles, try to purchase equipment with low blocking rate, which will save a lot of losses, especially for some units with more samples. Therefore, a Kangyu medical blood ball meter is equipped with an automatic blocking device to solve the blocking problem caused by various reasons, using high pressure blocking and unequal pressure on both sides to block; High-temperature burning, that is, under the condition of not affecting the instrument and test results, using the temperature higher than the protein ignition point to remove impurities such as macromolecular protein blocked in the small tube holes, so as to achieve the purpose of unblocking; Positive and negative impact, double-sided impact, is conducive to the fall off of adhesive fragments.
