KNF Diaphragm Pumps Are Essential Components of Biopsy Equipment
Biopsy equipment used for sample collection requires reliable vacuum for accurate results and low noise for patient comfort.

When dealing with potentially life or death medical conditions, a proper diagnosis is essential. Medical professionals rely on a variety of testing and analysis methods to ensure they are creating proper treatment plans for their patients. One of the most important methods for retrieving samples for medical testing is biopsy. This process often relies on medical equipment powered by vacuum pumps to obtain tissue or liquid samples from patients for testing.
Biopsy Helps Medical Professionals Diagnose a Variety of Conditions
Biopsy is a procedure that involves extracting cells, tissue, or fluids from the body for medical testing. Typically, biopsy procedures involve using a needle to reach the intended sample within the body before using suction to extract the desired material. It is used for diagnosing lymph node, liver, and kidney diseases, as well as for monitoring the activity of inflammatory diseases like Crohn’s. It is especially common for detecting cancer, as samples can be taken directly from lumps or tumors.
There are several different types of biopsy procedures, including fine needle, core needle and vacuum assisted variants. Which of these processes is used depends on a variety of factors, including the type of material being extracted and the part of the body it is being extracted from. These procedures rely on very precise equipment that operates in close proximity to patients. Many biopsy devices rely on diaphragm pumps to provide optimal performance and improve patient experience.
Strong Vacuum and Low Noise are Essential for Biopsy Equipment Pumps
While there are a variety of different biopsy procedures, they all involve equipment that needs to meet very strict requirements. Many types of biopsy equipment need to generate reliable, strong, and variable vacuum and pressure for sample collection. The deeper in the body the sample is taken from, the stronger the vacuum required. Strong vacuum is also required for higher viscosity samples. Because the biopsy equipment operates in close proximity to patients and medical staff, it needs to operate quietly and with minimal vibration.
KNF Diaphragm Gas Pumps Provide Control, Quiet Required of Biopsy Applications
For smaller biopsy equipment, KNFs NVC 830 is a strong option. It is equipped with Vacuum Control intelligent features, with integrated sensors and advanced software for precise control. This detailed control ensures the fast, consistent, and reliable vacuum required of biopsy applications. The NVC 830 offers a maximum vacuum of 200 mbar (abs.) and maximum flow rate of 3.6 l/min. Provides optimal performance and offers quiet operation with minimal vibration.
For other biopsy applications, KNF’s N 838.1.2 may also be appropriate. It offers a maximum vacuum of 90 mbar (abs.), maximum flow rate of 60 l/min, and maximum pressure of 0.5 bar (rel.). The N 838.1.2 offers outstanding reliability and strong performance along with compact design and oil-free operation. It is available with a variety of motor options, including an advanced MI motor for advanced control and long service life. The N 838.1.2 also produces minimal noise and vibration, and is available with other head configurations for applications requiring even lower vacuum.
For biopsy applications requiring further control, the MGP 75 may be a preferred option. It offers a maximum vacuum of 140 mbar (abs.), maximum flow rate of 72 l/min, and maximum pressure of 0.4 bar (rel.). The MGP 75 is equipped with KNF’s Pressure Control intelligent feature for precise regulation and detailed performance information. It also offers extremely quiet operation, minimal vibration, and long service life.
