NEST Petri Dishes are precision-molded using USP Class VI virgin polystyrene and manufactured in a Class 100,000 cleanroom. Certified to ISO 9001 and ISO 13485 standards, they meet the highest quality requirements for laboratory and medical applications. NEST Petri Dishes are an essential tool for microbiological studies, offering clarity, sterility, and

reliability for a wide range of laboratory procedures.

Safelock Design"

NEST Petri dish with safelock design has several protrusions on the top circumference of the dish body, and several buckles corresponding to the protrusions on the inner circumference of the cover; The lower end of each buckle is designed with a slope surface, and the upper end is designed with a card slot that allows the protrusion to slide into. After the medium is filled, turn the dish lid clockwise, and screw it into lock position to realize the lock function. This unique structural design ensures that the lid and the bottom of the dish will not fall off automatically during the experiment, avoiding contamination.

FAQs:

Are 90 mm Petri dishes the same as 100 mm Petri dishes?

In laboratory practice, 90 mm Petri dishes are commonly referred to as “100 mm Petri dishes.” The actual external diameter is typically around 90 mm, but they are considered the industry-standard full-size microbiology plate format.

Why are 90 mm dishes often called 100 mm dishes?

The terminology comes from historical laboratory conventions and manufacturer rounding practices. Many laboratories, distributors, and equipment manufacturers use the terms interchangeably for standard microbiology culture plates.

What is a safety lock Petri dish?

A safety lock Petri dish features an integrated locking design that helps secure the lid during handling and incubation.

Why use a safety lock Petri dish?

The locking mechanism helps reduce accidental lid separation, contamination risk, and sample disturbance.

What applications benefit from safety lock dishes?

Environmental monitoring, sample transport, teaching laboratories, and workflows involving frequent plate handling.

Can safety lock dishes help reduce contamination?

Yes. Improved lid stability helps minimize accidental environmental exposure.

Are safety lock Petri dishes suitable for microbiology culture?

Yes. They are commonly used for bacterial, fungal, and environmental microbiology applications.

Can safety lock dishes reduce the need for additional sealing?

In some workflows, the locking mechanism may reduce the need for tape or parafilm, depending on laboratory protocols.
