Lab quality borosilicate ("Pyrex") glass test tubes, beakers, flasks, graduated cylinders. Suitable for science, kitchenware, packaging, promotion. Buy just 1 or 2 or save up to 50% off by the case.
Just about everyone is familiar with test tubes, beakers, flasks & graduated cylinders. Long a staple of chemistry laboratory experiments, these heat resistant items are finding their way in the mainstream of daily use. Their utility for mixing, measuring, heating & storing liquids, is proving useful for presentation & display, promotion & packaging.
The properties that make borosilicate glass the material of choice for chemistry experiments makes it equally compelling outside the lab.
We carry the most types of laboratory glassware for displaying, heating, mixing, pouring or storing.
Why choose glass for packaging or storage? Glass is actually one of the only mainstream packaging materials that the U.S. Food and Drug Administration has recognized as truly safe. Besides being safer, it also has environmental benefits.
Glass is the most stable packaging material available. It is inert and impermeable with no risk of harmful chemicals getting into or reacting with your products of food products. Unlike plastic, there is no risk of potentially toxic chemical additives leaching out & into your food.
Recycling has its costs and glass is a more sustainable alternative to plastic packaging and more environmentally friendly. Glass is dishwasher safe & can be reused over and over with little diminishing of quality. Glass tubes and beakers are a fantastic way to package & repackage your products.
Our scientific glassware is designed for use in the lab environment. Beakers, flasks & graduated cylinders have graduation markings for measuring. Test tubes are completely unmarked and like (except 13x100mm) our Erlenmeyer and Florence (boiling) flasks have thick tooled rims for safe stoppering.
These traits make our lab glass even more popular as kitchen & barware with beakers especially popular as promotional giveaways for tradeshows & even frosh freebies.
Here are just some of the ideas we've covered in our blogs over the years:
Borosilicate glass, commonly referred to as "pyrex" is used in all quality lab glassware. It's resistant to thermal shock and food safe because it is completely LEAD FREE! See the tables below for physical & chemical characteristics.
|Borosilicate Glass 3.3 Properties - Physical Data|
|Physical Performance||Numerical Value||Unit|
|Coefficient of mean linear expansion (20°C;300°C)||3.3 ± 0.1||10-6K1|
|Transformation Temperature||525 ± 15||°C|
|Softeninq Point||820 ± 10||°C|
|Working Point||1260 ±20||°C|
|Density at 20°C||2.23 ± 0.02||g/cm3|
|Mean Thermal Conductivity (20°C-100°C)||1.2||w/rn2k|
Glassware cannot be returned for any reason; this is for your safety and ours. It would be prohibitively expensive to test for bacteriological, chemical or radiological agents since there is no way to tell if glass has been contaminated just by looking at it. We would have to throw it away even if you claim to never have opened the package.
However, if the item is broken, clearly defective in some way such as severely bubbled or chipped, send us an image & we will refund you.
