Culture and media-preparation glassware
- Culture or test tubes with suitable closures
- Borosilicate conical flasks for media preparation
- Media and reagent bottles with compatible caps
- Glass Petri dishes where validated reusable dishes are required
- Measuring cylinders, beakers and funnels for preparation work
Measurement and liquid transfer
| Item | Purpose | Selection check |
|---|---|---|
| Volumetric flask | Preparing a defined final volume | Class, capacity and calibration temperature |
| Graduated pipette | Measured liquid transfer | Range, graduation, accuracy and pipetting aid |
| Measuring cylinder | Routine volume measurement | Capacity, graduations and stability |
| Micropipette with compatible tips | Small-volume transfer | Volume range, calibration and contamination-control method |
| Dropping or reagent bottle | Controlled storage and dispensing | Chemical compatibility, closure and labelling |
Microscopy and staining items
- Microscope slides and cover glasses
- Staining jars, troughs or racks
- Pasteur pipettes or droppers where the method permits
- Coplin jars or equivalent staining vessels
- Immersion-oil and slide-storage accessories as required
Plan for sterilisation and contamination control
Confirm that reusable glassware, caps and markings tolerate the selected washing and sterilisation process. Avoid overcrowding loads, inspect glassware for cracks or chips, and separate clean, used and contaminated items through the workflow.
- Choose compatible borosilicate or specified material for thermal cycling.
- Use closures that permit the validated sterilisation process where required.
- Provide dedicated trays, racks and carriers for safe movement.
- Define inspection, washing, drying, storage and discard procedures.
How to estimate quantities
For each method, multiply the glassware used per batch by the number of daily batches, then add the sets required while used items are washing, drying, sterilising or held for quality checks. Include breakage allowance according to local experience rather than applying one universal percentage.

Frequently asked questions
Is borosilicate glassware required in microbiology laboratories?
Borosilicate glassware is commonly selected for items exposed to heating and thermal cycling, but the correct material depends on the method, sterilisation process and manufacturer instructions.
How many sets of microbiology glassware are needed?
Calculate items used per batch, daily batches and the turnaround time for washing, drying and sterilisation. Add enough sets to prevent the cleaning cycle from interrupting the workflow.
Can chipped laboratory glassware still be used?
Chipped or cracked glassware can fail, injure users or compromise cleaning and should be removed from service according to the laboratory’s inspection and disposal procedure.
