Plastic is preferred over glass because it is less likely to shatter and cause contamination
Plastic containers used in laboratories are called "labware". Traditionally, glass and steel labware were the choice of laboratories worldwide. Glass was preferred due to its transparency, low reactivity with reagents, reusability, and economic costs. However, with advancements in technology, plastic has gradually replaced glass in many labs due to its advantages.
Plastic labware is now the preferred material for containers in many laboratories. This is mainly because plastic containers are less likely to shatter and cause contamination. The use of new types of non-cytotoxic resins in plastic labware ensures that it does not interact with organic life forms, which is crucial for pharmaceutical and microbiology labs to prevent microorganism interaction with container materials. The leachable and extractable profile of plastic containers means they do not affect samples.
The resilience of plastic containers is higher, making them more shock-absorbent and less likely to break if accidentally bumped or dropped. This enhances the safety of scientists, preserves samples, and reduces the costs associated with breakage and replacement. Plastic containers are also lightweight, making them easier to carry and reducing delivery costs. The lightweight property is especially advantageous in robotic-assisted labs, as it reduces the stress on the containers and the risk of damage, preventing unwanted leakage and interruptions in research.
It is important to consider the stability of plastic containers, especially in environmental applications, as trace contamination can be a concern. Plastic containers made with PTFE (Teflon) are highly durable and resistant to deposition, dissolution, or breakdown. The resin composition of plastic containers should be carefully selected to suit the specific laboratory requirements. Plastics with minimal additives and reduced leachables are preferred to ensure no impact on the reagents or samples they contain.
