Paraffin embedding machine is the human body or animal and plant specimens after dehydration wax embedding tissue wax block for histological diagnosis or research equipment after slicing, suitable for medical colleges, hospital pathology, medical research units, animal and plant research units and food testing and other departments.

Multi-function embedding machine

Before embedding, pathological tissues will undergo some procedures such as fixation, washing, dehydration, transparency, wax penetration, etc. These operations will use many solvents, mainly formalin, alcohol, xylene, paraffin, etc. Due to the volatile organic compounds of formalin and xylene, the smell is very pungent and the potential harm to human body is very large. So it can be used in the process of tissue fixation and transparency.2To3A liquid level switch, so as to realize the automatic detection and injection of dangerous solvents, to prevent solvent overflow, so as to realize automatic control. The realization of the automatic detection can avoid the staff from being poisoned by harmful substances too frequently.

1. pathology tissue fixation process

United KingdomSSTCompany launchedLLT200D3SH(See the figure below) Its material (TrogmidMaterial) Its high temperature resistance and corrosion resistance make it extremely compatible in the formalin solution during pathological tissue fixation. The sensor can work at high temperature, has long service life, sensitive detection, and high reliability. At present, foreign technology The automatic dosing of pathological equipment in the cutting-edge tissue fixation adopts this scheme. Domestic customers use ultrasonic testing solutions, but the reliability and sensitivity are poor.

2. pathological tissue transparent process

DueLLT200D3SHThe xylene liquid used in the transparent process after the dehydration of pathological tissues is not very compatible, due to the corrosion and solubility of xylene.LLT200D3SHThe surface becomes soft, so the detection of xylene liquid requires a more robust stainless steel package, the top tip isSimaxof crystal glassPOSSeries sensors to detect. At present, the excellent cost performance of the sensor makes the sensor widely used and praised in the pathological equipment research and development and production industry.
