Our company has independently developed a batch of equipment, including the dry state microbial penetration tester PK226 and the wet state microbial penetration tester PK236,

It has been successfully installed and debugged at Guangzhou Institute of Microbiology and Guangzhou Tianxiang Testing Technology Service Co., Ltd. (ITS), and the customer is very satisfied with the performance and service of the product. Currently, over a hundred enterprises and third-party testing units (companies) are using it. Customer satisfaction is our motivation for HAO, and we will continue to provide high-quality services to our customers.

The Guangzhou Institute of Microbiology relies on multiple biology professors, senior engineers, and PhDs as technical support, and has more than 30 experienced middle and senior technical personnel. It has established public technical service platforms such as the Guangzhou Fermentation Engineering Technology Research Center, Biological Raw Material Outsourcing Service Platform, Central Laboratory, Guangzhou Industrial Microbial Testing Center, and Guangdong Microbial Germplasm Resource Bank.

Mainly engaged in microbiological testing of industrial products, with the dual certification qualifications of National Laboratory Accreditation (CNAS) and Metrology Accreditation (CMA). The testing reports issued are mutually recognized within the Asia Pacific Laboratory Accreditation Cooperation (APLAC) and the Laboratory Accreditation Cooperation (ILAC), and are widely used in trade certification, product quality evaluation, and achievement appraisal as fair data with legal effect

Dry state microbial penetration tester

Product Model:PK226

Compliant with standards:

ISO 22612Infectious pathogen protective clothing Test method for penetration of dry state microorganisms

YY/T 0506.5-2009Surgical sheets, gowns, and cleanroom gowns for patients, medical staff, and equipment 第5part:Test method for penetration of dry state microorganisms

Product Introduction

Numerous examples have shown that bacteria can penetrate shielding materials with dry organic or inorganic particles, such as skin flakes carrying bacteria penetrating surgical gowns or cleanwear, or particles carrying bacteria penetrating packaging materials during storage.

DryPenetrationThe dry state microbial penetration tester is used to determine the performance of material impedance in penetrating bacteria on dry particles within the size range of human skin flakes.

Test Principle

Fix the six containers onto the stone slab with fixed plates and fixtures, and fix the sterilized samples onto the containers with lids. Add bacterial stained talc powder to the specimens through the piston port (add uncontaminated talc powder to the sixth container as a control container), and insert the uncovered culture dish into the bottom of each container. Every minute20800Secondary vibration frequency vibration30Minutes, take out the culture dish35ºCcultivate24Hour by hour, count the formed colonies.

Moisture resistant microbial penetration tester

Model:PK236

Instrument usage：

In today's society where people's awareness of personal protection has greatly increased, the control of cross infection during surgical procedures is increasingly receiving attention. Research has found that cross infection in operating rooms is mostly caused by microorganisms from the skin of patients or medical staff penetrating barrier materials such as surgical gowns or sheets. The antimicrobial penetration resistance of surgical gowns and surgical sheets is increasingly being valued. Establishing experimental methods for evaluating the microbial penetration resistance of surgical gowns and surgical sheets as soon as possible in China has become a focus of attention for industry professionals.
Surgical gowns and surgical single barrier microbial penetration performance refer to the ability of materials to prevent microorganisms from passing from one side to the other. The state of microorganisms in clinical practice includes two situations: dry and wet. Dry penetration refers to particles such as human dander that may carry microorganisms passing through non critical areas of surgical gowns and sheets (which can spread to open surgical areas in the air); Wet penetration refers to the penetration of body fluids that may carry pathogenic bacteria during surgery through key areas of surgical gowns and surgical sheets (directly reaching the protected object) under the combined effects of pressure and friction.
Wet state bacteria resistance tester, also known as“ Wet state microbial penetration tester ", wet state microbial penetration tester series standardISO 22610The instrument for penetration testing of moisture resistant microorganisms is also a standard of the China National Food and Drug AdministrationYY/T 0506.6Experimental instrument for penetration test of moisture resistant microorganisms.

Basic Technical Specification Description

This instrument has an electric drive, electronic timer control, and a speed of60rpmThe turntable can be installed with one14cmA diameter agar culture dish. The balance bar with test fingers is rotated at a speed of5.60rpmGuided by the eccentric axis, gravity can be3±0.02NThe experiment refers to the lateral reciprocating motion from the center to the periphery of the turntable. Within a test cycle, the superposition of two movements can evenly distribute the trajectory of the test finger over the entire surface of the disc. The total weight is800±1gThe inner and outer steel rings are used in the experiment to clamp the test material and apply standard tension to the material. The instrument also comes with a diameter9cm, high4cmA cylindrical body used to provide a flat surface and uniform tension during the fixation process of three-layer materials.
