Merck, 1178840001, Magnetic perforated lid Microbial Air Sampler

General description
Perforated lids are crucial for optimizing the physical and biological sampling efficiency of Andersen impaction-based microbial air samplers. Air is accelerated through the perforations in the lid, creating a jet that impacts the agar surface.
The Lid for MAS-100 Sirius Microbial Air Samplers is designed to fit tightly on the instrument by easy and quick magnetic closure without twisting.
It is made from 316L stainless-steel which has good resistance towards a broad range of disinfectants including vaporized hydrogen peroxide and is suitable for autoclaving.
The magnetic lid type B 90 mm has a sieve geometry of 400 holes with a diameter of 0.7 mm and is suitable for use with 90 mm agar plates. This sieve configuration delivers a nominal d50 value of 1.15 µm at a flow rate of 200 SLPM (standard liter per minute).
Each lid is marked with laser-based marking without significantly altering the properties of the metal surface. The information of the unique marking includes the identification code of the perforated lid as well as the serial number in barcode and readable format.
Application
The perforated lid is designed for active air monitoring with MAS-100 Sirius instruments at a flow rate of 200 standard Liter per minute (SLPM) using 90 mm agar plates such as ICR/ICRplus settle plates, enabling efficient air sampling in Isolators and cleanrooms.
Features and Benefits
Independently validated efficiency acc. ISO 14698 and EN 17141 at a flow rate of 200 SLPM with ICR settle plates
Stainless-steel for optimized cleaning and sterilization
Unique marking allows manual and digital tracking
