   Furniture companies generally use water-based milky white glue (polyvinyl acetate glue). In recent years, the standard detection of the bamboo and grass registration system has rarely detected unqualified free formaldehyde. However, furniture companies will use epoxy resin commonly known as " iron glue " when special-shaped structural parts with high adhesive strength are required . It has excellent characteristics such as strong adhesion and low shrinkage. It usually includes component A and group B. Minute. Component A is generally a mixture of epoxy resin and diluent, and component B is generally a curing agent. " Iron glue " diluent may contain benzene, toluene, xylene, and must contain VOC substances. Some cheap epoxy resin adhesives are actually epoxy - phenolic resin adhesives. The glue contains phenolic resins and may contain free formaldehyde. In addition, some glue manufacturers add formaldehyde solution as a preservative to the product and cause free formaldehyde to exceed the standard.
   In this regard , the inspection and quarantine department reminds relevant enterprises to strictly implement the raw material testing and control requirements of the bamboo and grass registration system , regularly sample and verify the raw materials, and also include auxiliary materials with a small amount of consumption into the scope of testing and monitoring.

The conductive Pipette Tips are specially designed for automatic workstations and are made of medical grade conductive polypropylene (PP) material, and the tips are conductive. After the conductive tip is adapted to a specific automatic pipetting workstation, it can detect the liquid level, making the automatic sample addition more intelligent and precise.
Transparent automatic Pipette tips can also be called robotic pipette tips or micro tips; Yongyue Medical's pipette tips have been sterilized and are packaged with 96 pieces per box, which is easy to carry and operation; compatible for Beckman, Tecan, Rainin to achieve automatic pipetting performance and ensure the consistency of pipetting.
The robotic tip is made of imported polypropylene (PP) material, with high transparency. The surface is treated with a special process and has super-hydrophobicity to ensure the accuracy of experimental data. The product is automatically produced in a 100,000-level purification workshop, free of DNase, RNase, and pyrogen-free.
