Deciding between glass and plastic labware


Two of the main reasons for plasticwares' popularity is its unbreakable nature and compatibility with common laboratory chemicals.

Glassware’s biggest drawback of accidental breakage can result in the loss of valuable samples, toxic spillages, or even injuries to the lab tech or scientist. Contamination of samples due to leaching metals or other inorganics and exposure to light are also a concern.

Some of the biggest advantages of reusable plastic labware is its non-breakable, leakproof nature. It’s lightweight which makes it easier to handle and it can be reused after proper cleaning, which helps save on replacement costs and lowers the environmental impact.

High-quality resins mean low-level extractables

When plastic is the way to go, there are a lot of plastic labware choices on the market. But the quality of your work depends on using quality lab supplies that perform up to laboratory standards. Low quality plastics can contain significant amounts of additives and impurities that might leach into your solutions.

Nalgene containers are made from only the highest quality pharmaceutical, laboratory and food grade plastic materials and meet accepted ASTM and ISO accuracy standards. Our resins are selected to minimize additives and reduce potential leachables. We don’t use plasticizers or fillers, and our plastics have lower total ash content – a measure of impurities – than the plastics used in competitive container offerings.

The term “leak proof” applies to Thermo Scientific Nalgene products that meet the following criteria: a) Bottle/flask/funnel closure systems with closures smaller than 100mm, after they are filled with water, inverted, withstand air pressure of 2psig for 2 minutes, and no water escapes;. b) Bottle/funnel/flask closure systems of larger than 100mm after they are filled with water, inverted for 15 minutes, and no water escapes. Note: these tests, using other liquids, may not yield the same results. To ensure safe usage, customers are advised to test Thermo Scientific Nalgene bottles and closures under conditions of their planned applications. Thermo Scientific Nalgene products are leak proof at ambient temperature and pressure when used with their Nalgene closures
