Placa de contacto
A 55 mm prepared agar plate with a raised convex surface for direct microbial sampling of cleanroom surfaces and personnel.
- Raised Contact Agar Surface
- 55 mm Monitoring Format
- Neutralizer Options
- Sterile Lockable Plate
Introducción del producto
The Contact Plate is filled so the agar forms a smooth convex surface above the dish rim. Removing the lid allows the medium to touch a defined area of a dry flat surface or a gloved fingertip without scraping the plastic edge. After controlled pressure and dwell, the plate is closed and incubated for recovery and enumeration. Critical-area formats use gamma-irradiated triple wrapping, while lockable lids, data identification and neutralizer blends support secure cleanroom workflows.
Características clave
The compact 55 mm format fits common surface, glove-print and active-air accessories.
Neutralizer blends reduce inhibition by residues from routine disinfectants.
Lockable and sterile triple-wrapped formats support critical-area transfer and transport.
Preocupaciones del producto del cliente
Contact plates must provide uniform contact while avoiding agar damage, disinfectant inhibition and loss of sample identity.
A recessed agar surface cannot fully touch the monitored surface.Convex filling raises the medium above the rim for a broad defined contact area.
Residual sanitizer suppresses growth and masks viable contamination.Optional lecithin, polysorbate, histidine and thiosulfate neutralize a range of common residues.
The lid opens during transfer to the incubator.A positive lock option keeps the closed plate secure during handling.
Critical-zone unpacking introduces contamination.Gamma irradiation and staged triple wrapping support controlled transfer into isolators and cleanrooms.
