Product Overview

Small Glass Petri Dish is compact borosilicate 3.3 glassware for micro-scale microbial culture, cell inoculation, small-volume reactions, teaching demonstrations, and research sample handling. The 35mm, 40mm, and 50mm formats help reduce reagent use while keeping samples separated for incubator loading, microscope checking, and batch labware supply.

Key Features

Compact format for limited reagent volume: 35–50mm dish sizes and 5–15ml capacity fit micro-culture, inoculation, and small-volume reaction work where reagent use must stay low.
Borosilicate 3.3 glass for chemical-contact lab work: the lead-free and arsenic-free glass surface stays stable during contact with acids, bases, and organic solvents.
Matched lid and base for shallow media: the lid/base fit slows moisture loss from small media volumes during short culture or demonstration work.
Polished edge and smooth surface for repeat handling: fusion-molded glass with round burr-free edges reduces sharp-edge contact during washing, sterilization, and packing.

Customization Options

Size version: 35mm, 40mm, and 50mm standard formats plus drawing- or sample-based small-dish dimensions.
Glass structure: bottom thickness, lid thickness, and dish height matched with the approved sample.
Packing version: bulk packing, inner bag or box packing, set packing, label version, barcode label, and carton mark.
Branding: private-label packing, product label, outer carton mark, and batch label for distributor supply.

Packaging and Order Information

Pre-production samples are supplied before bulk production; custom sample development cycle is 2 weeks. The sample item is free; freight is paid by the receiver.
Custom production schedule: custom production adds 1–2 weeks to the base production plan after the sample and packing version are approved.
Mixed order support: custom orders can include mixed dish sizes or models in one order plan.
For packing protection, matched lid/base sets are packed with inner protection, quantity labels, batch/carton marks, and export cartons for glassware shipment.

Quality Control

Small Glass Petri Dish quality checks cover compact size consistency, shallow capacity, glass clarity, polished round edges, and lid/base matching. Finished dishes are compared with the approved sample and specification, and pieces with cracks, bubbles, scratches, sharp edges, unstable fitting, or inconsistent diameter are removed before packing.

FAQ

Q1: When should the small glass Petri dish be chosen?

A1: Use it for micro-scale culture, small-volume reactions, inoculation checks, and teaching demonstrations where 35mm to 50mm dishes reduce reagent and media use.

Q2: How should 35mm, 40mm, and 50mm sizes be chosen?

A2: 35mm fits very small samples, 40mm gives more handling space for teaching and routine checks, and 50mm is used when the sample needs a wider culture surface.

Q3: Can it handle repeat sterilization?

A3: Yes. The borosilicate 3.3 glass body holds up to repeat autoclave and dry-heat sterilization when cleaned and handled under normal laboratory procedures.

Q4: What information do you need if small dishes arrive broken?

A4: Send photos of the broken dishes, outer-carton condition, affected size, affected quantity, and order number so we can check the case against the shipment batch.
