What Is a Petri Dish?

Petri Dishes. Petri dishes are available in a variety of shapes and sizes for use in routine procedures and with automated equipment. Economical, optically clear dishes are precision-molded from biomedical grade polystyrene so cultures are clearly visible without distortion. Petri Dishes are packaged in heavy-wall polyethylene sleeves

What are the Most Popular Petri Dishes?

Nest Scientific Petri Dishes – Unobstructed Viewing of Bacterial Cultures Nest Scientific Petri Dishes are designed to be used for bacterial cell culture applications in all types of labs. These NEST Scientific dishes are manufactured from high clarity, non-treated polystyrene and feature a flat, transparent surface for unobstructed viewing of the bacterial cell cultures contained within the dish. Each case of Nest Scientific dishes is packaged into PA/PE sleeves of twenty dishes each per PA/PE sleeve, which makes them ideal for maintaining sterile technique and working in smaller batches if needed, depending on your application needs and requirements. These Nest Scientific dishes feature three vents for gas exchange and a bottom ridge allowing for easy handling, transport and storage of the Nest Scientific dishes, as well as compatibility with automation systems. They are shipped and packaged DNase and RNase free and non-pyrogenic due to E-beam sterilization to provide you with optimal sterility.

CELLTREAT Petri Dishes. CELLTREAT Non-Treated Cell Culture Dishes CellTreat Non-Treated Cell Culture Dishes have a stronger, heavier construction compared to traditional Petri dishes These dish types can be used for the same applications as regular Petri dishes. The surface is hydrophobic and does not facilitate cell attachment. These culture dishes are available in four diameters: 35, 60, 100 and 150mm. The 35 mm dish has an off-set bottom for improved handling. 60 and 100 mm dishes are available with a pronounced grip ring for improved handling. Vented lids on these dishes contain molded spacers for gas exchange (Except part no. 229655 which has a non-vented lid). These dishes have a stackable lid design for increased stability and are packaged sterile (gamma irradiated).

How to wrap petri dishes in parafilm?

Parafilm is a thermoplastic, self-sealing film, it is ideal for the scientific laboratory. Because it is stretchable, moldable, waterproof, and self-adhering, as a sealing film, Parafilm holds moisture loss to a minimum. As a sealing film, it is commonly used for sealing or protecting vessels as it offers excellent protection for the contents of tubes, flasks, and petri dishes. Parafilm is also used to further seal a lidded container against moisture for long term storage.
