Sterile 3-Compartment Petri Dishes (90mm, 20 Pack)

Title: Sterile 3-Compartment Petri Dishes (90mm, 20 Pack)

Description:

These sterile, vented, three-compartment Petri dishes are a versatile laboratory essential. Made from crystal-clear, neutral polystyrene for single use, these 90mm dishes offer excellent visibility of their contents. The design includes three separate sections within a single dish, facilitating multiple experiments or samples simultaneously. The vented lid features three aeration supports, promoting aerobic microbial cultivation while preventing condensation. For anaerobic cultures, simply remove the lid supports to create an airtight seal.

These robust dishes boast a density of 1.05 g/cm² and a temperature resistance range of -10°C to +70°C (maximum recommended temperature for molten agar pouring: +55°C). They exhibit low water absorption (<0.05%) and excellent chemical resistance to a wide range of substances, including oils, alcohols, bases, fats, salts, and various acids (boric, citric, formic, hydrofluoric, lactic, oxalic, salicylic, tartaric), hydrogen peroxide, phenol, potassium permanganate, triethylene and tripropylene glycol, and urea.

Beyond microbiology and chemistry applications, these versatile Petri dishes are ideal for storing small samples, evaporating liquids, preparing small plants and animals, and even etching small circuit boards. They also find use in terrariums as breeding substrates, particularly for amphibians such as poison dart frogs. This 20-pack provides ample supply for various laboratory and hobbyist needs.
