Introduction de produit

The Surface Microbial Sampler is a precision contact weight used with raised-agar contact plates. Its balanced stainless body seats over a standard plate holder and transfers a controlled vertical load to the agar while a small timer defines the dwell period. A spring-guided plunger helps the operator maintain even contact without rocking the plate or concentrating force at one edge. After sampling, the plate is removed and capped for incubation, leaving the applicator available for cleaning or steam sterilization.

Key Features

A defined weighted load reduces operator-to-operator variation in plate pressure.

The plate-retaining collar centers the contact dish beneath the applicator.

A pull-out timer standardizes the selected contact duration at each location.

Smooth stainless components tolerate repeated cleaning and sterilization.

Préoccupations du client produit

Surface recovery varies when operators use different pressure, dwell time or plate angle on the same material.

Hand pressure differs between technicians and sampling rounds.A fixed applicator mass supplies the same nominal load without relying on operator force.

Tilting the plate traps air or contacts only part of the agar dome.A centered collar and guided vertical motion support even face-to-surface contact.

Short or inconsistent dwell time reduces comparability.The integrated timer gives a visible repeatable contact interval.

Complex joints retain disinfectant or surface residue.Removable smooth stainless parts simplify wiping and validated sterilization.
