Gridded Membranes
A grid supports colony counting. Confirm material, pore rating and incubation conditions against the test method.
LABORATORY / Microbiology Supplies
For incubation and counting workflows. Specify diameter, depth, sterile status and packaging.
Images and specifications refer to the indicated models. Contact us to confirm configuration and suitability.
A Petri dish provides a level support for growth medium and a space for observing cultures. The base and lid are generally not a hermetic seal; their geometry influences evaporation, gas exchange and condensation. Microbiological culture, membrane incubation and cell culture have different surface requirements, even when the vessels look similar.
| Selection factor | What to compare |
|---|---|
| Diameter and depth | Balance medium volume with counting area and practical stacking space. |
| Base format | Plain, divided and gridded bases support different observation methods, not different sterility grades. |
| Packaging | Aseptic use requires intact packaging and controlled exposure after a multipack is opened. |

| Material options | Polymer |
| Filtration objective | Define what to remove and what to retain |
| Rating / Dimensions | Confirm combinations against controlled model specifications |
| Flow / Temperature / Pressure | Specify normal and limiting operating conditions |
| Connections / Seals | Confirm installation interfaces and wetted materials |
| Cleaning / Validation | Confirm the service cycle and acceptance criteria |

Use the orientation and environment specified by the method to manage condensation.
Record time, sample identity and unusual growth while minimising repeated opening.
Microbiological dishes and vessels treated for cell attachment serve different purposes.
Evaporation depends on lid geometry, stacking, environment and incubation duration rather than diameter alone.
