Microbial Sampler Head
An electropolished stainless-steel sieve head that directs active-air samples uniformly onto prepared microbiological media.
- Precision Sieve Pattern
- Electropolished 316L Body
- Cleanable Sealed Joint
- Secure Bayonet Interface
Product Introduction
The Microbial Sampler Head is a removable flow-conditioning assembly for active viable-air monitoring. A precision perforated lid forms multiple controlled air jets over the culture medium, while the machined body maintains repeatable plate positioning and flow geometry. Electropolished stainless steel, a replaceable elastomer seal and a positive mounting interface support cleaning, decontamination and routine controlled-area use.
Key Features
Electropolished 316L stainless steel resists common cleanroom disinfectants.
A removable lid and accessible surfaces simplify cleaning and sterilization.
Bayonet or threaded mounting keeps the head stable during calibrated sampling.
Customer Product Concerns
The sampling head must preserve collection efficiency while remaining cleanable, securely mounted and geometrically repeatable.
Uneven air jets overload one area of the agar plate.A concentric precision-hole pattern spreads impaction over the usable collection surface.
Residue trapped in rough metal surfaces compromises cleaning.Electropolished stainless steel provides a smooth accessible product-contact finish.
Head movement changes the air path during a sample cycle.A positive bayonet or threaded interface locates the head securely on the sampler.
Repeated sterilization degrades sealing performance.A replaceable silicone O-ring maintains a defined cleanable joint.
Typical Applications
Active cleanroom air monitoringIsolator and RABS samplingPortable viable-air sampler accessoriesRemote fixed sampling points
