Introduction de produit

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.

Key Features

A raised agar dome makes direct contact across the full nominal sampling area.

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.

Préoccupations du client produit

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.
