Weighing Dishes


Style A	Style B	Style C	Style D

Style E	Style F	Style G

Style D—Styles D dishes have a center hole for compatibility with analyzers that use a center stem for precision weighing. They have deep compartments that collect liquid, keeping it away from the sensitive balance components in the center.

Style E—Styles E dishes have a center hole for compatibility with analyzers that use a center stem for precision weighing. They have shallow compartments to distribute solid particles evenly. They’re not recommended for use with liquid.

Petri Dishes


Round	Square

Borosilicate Glass—Glass petri dishes have a reinforced edge to prevent breakage.

Vented Lid—Vented lids are raised just above the dish to allow airflow.

Bottom-View Bench Inspection Mirrors

Spot settled particles that could indicate irregularities in batches. Rather than lifting your sample over your eye line, place your sample on top of the clear platform. The mirror magnifies its underside. First designed for looking at petri dishes in labs, they’re also used in food manufacturing, chemical processing, and water treatment. Just place a clear container of your liquid on top of the platform and tilt the mirror as needed.

Well Plates

Cover	Tight-Fitting Covers

Each well on these plates acts as a mini test tube, allowing you to collect, mix, and store up to 96 individual samples within a single container. Keep track of the location of each of your samples using the labeled grid.

Round Top—Plates with round wells are better for sample mixing than plates with square wells.

U Bottom—Those with U-bottoms facilitate mixing even further.

V Bottom—Those with V-bottoms make it easy to retrieve the final drops of a sample, reducing waste.

Covers—Add a cover to your plate to protect samples during processing and storage. Covers also make plates stackable. Tight-fitting covers have grooves that protect each well. They prevent evaporation and contamination better than standard covers.
