Buying Guide

Choose the right diameter

60 mm dishes are common for colony counts and teaching labs while 90 mm dishes give more growth area for larger cultures or multitesting

Sterile vs. autoclavable

Pre-sterilized dishes save prep time for single-use work, while autoclavable dishes are reusable and better for labs that sterilize in-house

Consider material and thickness

Thicker polystyrene or PC (polycarbonate) increases durability and reduces warping during incubation and handling

Pack size and cost per dish

Higher pack counts lower per-dish cost and reduce ordering frequency; match pack size to projected experiment volume to avoid waste

Lids and sealing options

Secure-fitting lids help reduce contamination; verify compatibility with common sealing films or parafilm if long incubations are expected
