Petri Dish Guide: Uses and Applications in Laboratory Work

Make Laboratory Workflows More Consistent

Laboratory workflows are familiar in many settings, but steady results depend on more than one piece of equipment. We know that the laboratory equipment used to prepare, mix, warm and handle samples can shape how smoothly the whole workflow runs.

From early preparation through to sample processing and bench set-up, each step benefits from tools that suit the work at hand. August is a useful time for Australian laboratories to review winter workloads, restock routine supplies and prepare benches for upcoming research, teaching and industrial projects.

Prepare Materials with Heating and Stirring Equipment

Before materials move through a workflow, they often need careful mixing or warming. We recommend matching your Magnetic Stirrer and Hot Plate to the type of preparation you carry out most often. Controlled stirring helps keep mixtures more even, while a Hot Plate provides a steady source of heat when warming is required.

Water Baths and Dry Baths offer a different kind of temperature control. A Water Bath may suit tasks needing gentle, even warming, while a Dry Bath can be a practical choice when working with compatible tubes or vessels. The right option depends on your routine temperature range, expected sample volume and available bench room.

Laboratory Jacks are small but helpful support tools in these tasks. They allow you to raise or lower vessels and equipment during heating, stirring or transfers, helping create a more comfortable and orderly work area.

When selecting preparation equipment, we suggest considering:

• The temperature range your work requires  
• How much material you prepare at one time  
• Whether continuous stirring is needed  
• The bench space available for each device  

Process Samples Efficiently

Sample preparation can be easier to manage when each device has a clear role. A Centrifuge or Mini Centrifuge can support workflows where samples need separating or concentrating before they move on to the next stage. When choosing between them, we encourage you to look closely at speed settings, capacity and the tube formats used in your routine processes.

Mixing equipment also matters. A Vortex Mixer provides fast agitation for short mixing tasks, while a Tube Mixer can support more controlled mixing across compatible tubes. Tube Rollers work differently again, using slower, continuous rolling where gentle ongoing movement is preferred.

A dependable sample preparation set-up usually comes from pairing complementary laboratory equipment rather than expecting one device to do every job. For example, a Centrifuge may support separation, followed by a Vortex Mixer for quick agitation or a Tube Roller for slower movement. By considering how each step connects, you can build a workflow that feels more organised from start to finish.

Improve Accuracy with Weighing and Temperature Control

Accurate measurement starts with a Lab Balance that suits the materials and quantities you handle. We recommend choosing a balance with the right readability level for your work, enough capacity for routine weighing and a footprint that fits comfortably into your workspace. A balance that is too large or too limited for the task can make daily preparation less convenient.

Temperature control should be selected with the same care. Water Baths provide gentle warming, Dry Baths suit compatible vessels, and Hot Plates support direct heating needs. Your choice can depend on the heating method, available bench space and the number of samples being prepared at one time.

Well-matched laboratory equipment can help reduce avoidable variation in routine preparation. It also makes it easier for teams to follow repeatable processes, keep benches organised and move through daily work with fewer interruptions.

Build a Safer, More Flexible Laboratory Set-Up

Some broader preparation processes require controlled vacuum capability. A Vacuum Pump can support these tasks when its performance specifications and accessories match the requirements of your set-up. We recommend reviewing compatibility before placing a pump into a workflow, including the connections, intended use and maintenance needs of the equipment around it.

Laboratory Jacks can add flexibility at the bench by making it easier to raise, lower and position equipment securely. This can be useful during practical heating, stirring and transfer tasks, especially where vessel height needs to be adjusted without changing the rest of the workstation.

A simple selection framework can help guide equipment decisions:

• Available bench space and power access  
• Expected sample volumes and throughput  
• Required temperature control and heating method  
• Mixing style, from rapid agitation to continuous rolling  
• Cleaning and maintenance requirements  

Choose Equipment That Supports Reliable Laboratory Work

Laboratory workflows are easier to manage when the preparation tools around them work together. Centrifuges, Mini Centrifuges, Vortex Mixers, Tube Mixers, Tube Rollers, Magnetic Stirrers, Hot Plates, Water Baths, Dry Baths, Lab Balances, Laboratory Jacks and Vacuum Pumps can each support a different part of the process.

As spring research, education and industrial activity approaches, we recommend reviewing your current set-up against the work your team expects to complete. The best choices are usually those that fit your routine sample volumes, mixing needs, temperature requirements and bench layout, creating a practical workflow that is easier to repeat each day.
