PALL 7232 Petri Dishes without Absorbant Pads, 50 mm, Gamma Irradiated, Bulk Pack (500/pkg)

PALL 7232 petri dishes are commonly used for sample handling, membrane filter support, culturing workflows, and other laboratory procedures that require a clean 50 mm dish format. Their compact size makes them useful in microbiology, environmental testing, and general lab applications where small-format sterile dishes are preferred. The product page specifies that this model is a 50 mm petri dish and is gamma irradiated, which supports use in controlled lab environments.

These dishes are described as gamma irradiated, which is commonly used as a sterilization method for disposable laboratory consumables. That makes them a practical choice for procedures where reduced bioburden and ready-to-use sterile handling are important.

“Without absorbent pads” means the dishes are supplied as plain petri dishes only, with no built-in pad inside the dish. This is useful for labs that want flexibility to add their own media, membranes, or sample material without an extra absorbent layer interfering with the procedure. The product description explicitly states that these are petri dishes, bulk pack, without absorbent pads.

The PALL 7232 petri dishes are made from polystyrene. Polystyrene is a common material for disposable lab dishes because it is lightweight, economical, and suitable for many routine laboratory applications.

This product is sold in a bulk pack of 500 dishes, which is helpful for laboratories with high sample throughput or routine testing needs. Buying in bulk can also help reduce the frequency of reordering for busy microbiology or filtration workflows.
