Shanghai Jinma Bio has gained a strong reputation among customers since the launch of its ELISA kits. This service allows more research institutions to benefit by offering real-time sampling, so customers don't have to worry about samples being damaged or delayed during shipping. However, effective sampling requires some expertise—do you know how to do it properly?
Today, Shanghai Jinma Bio is sharing some key insights on sampling: The "sampling interval" refers to the time between each sample collection or the stage in the development process. It's best to collect samples during key periods as much as possible. If the interval is too short, you may end up with an excessive number of samples, increasing both workload and resource consumption. On the other hand, if the interval is too long, you risk missing important samples from critical stages.
Our recommendation is to keep the sampling interval as short as possible, provided that it doesn’t lead to unnecessary testing later on. The goal is to capture all essential samples without overcomplicating the process. As for the number of samples, it’s generally advisable to collect more than the amount you initially plan to use. We suggest taking at least three times the expected number of samples to ensure enough for retesting or repeated measurements.
Shanghai Jinma Bio offers a wide range of testing services, suitable for most sample types. Whether you're working with biological, chemical, or electronic materials, we can help.

Die casting is the pressure of metal molds on a die casting machine and is the most productive casting process. Die-casting machines are divided into two categories: hot-chamber die-casting machines and cold-chamber die-casting machines. The hot chamber die casting machine has a high degree of automation, less material loss, and higher production efficiency than the cold chamber die casting machine. The aluminum alloy die castings that are widely used today can only be produced on cold chamber die casting machines due to their high melting point. The main feature of die casting is that the molten metal fills the cavity under high pressure and high speed, and is formed and solidified under high pressure. The air in the cavity is wrapped inside the casting to form subcutaneous pores, so aluminum alloy die castings should not be heat treated, and zinc alloy die castings should not be sprayed on the surface (but can be painted). Otherwise, the internal pores of the casting will expand due to thermal expansion and cause the casting to deform or bubble when the above-mentioned treatment is performed. In addition, the mechanical cutting allowance of die castings should also be smaller, generally around 0.5mm, which can not only reduce the weight of castings, reduce the amount of cutting to reduce costs, but also avoid penetrating the surface dense layer and exposing subcutaneous pores, causing The workpiece is scrapped.
