In any laboratory plasticware is an essential part of daily experiments, from beakers to pipettes. Though plastic laboratory tools are lightweight, durable, and cost-effective, improper use can compromise the integrity of your experiments and lead to contamination or inaccurate results. Here are some of the common mistakes made when using lab plasticware and tips on how to avoid them:
1. Using Plasticware for High-Temperature Applications
Plasticware, unlike glass, isn't designed to withstand high temperatures. Using plastic containers or tools with hot chemicals or heat sources can cause them to warp, melt, or release toxic chemicals.
Solution: Always check the manufacturer's guidelines for the heat resistance of your plasticware. For high-temperature procedures, opt for glassware designed to handle heat.
2. Inadequate Cleaning of Plasticware
Plastic materials can be prone to retaining residues of chemicals, oils, or reagents. Failure to properly clean plasticware after each use can lead to contamination or skewed results in future experiments.
Solution: Follow proper cleaning protocols for your plasticware, including washing with detergent and using a non-abrasive brush. Be sure to rinse thoroughly to avoid any lingering chemical traces.
3. Using Abrasive Materials
Some lab plastics can scratch easily, especially when cleaning with abrasive materials like scouring pads or harsh chemical solvents. Scratches can create crevices that harbor bacteria and make plasticware more difficult to clean.
Solution: Use only soft cloths or sponges for cleaning and ensure the cleaning agents you use are safe for plastics.
4. Not Storing Plasticware Properly
Improper storage can lead to damage or deformation of plasticware, especially when subjected to pressure or harsh environments. Solution: Store plastic containers and tools in a cool, dry place away from direct sunlight or extreme temperatures. Always ensure that plasticware is stored upright to avoid stress on the material.
5. Using Plasticware for Long-Term Chemical Storage
Some chemicals, especially solvents or aggressive acids, can degrade plastics over time, leading to leaks or structural failure.
Solution: Always check chemical compatibility with the plastic material. For long-term storage, consider using glassware or specialized containers made for specific chemicals.
Conclusion:
While lab plasticware offers many advantages, avoiding these common mistakes can help ensure the longevity and accuracy of your experiments. Proper use, cleaning, and storage are key to maintaining the reliability of your tools.
