Laboratory Glassware That Actually Holds Up

You know how frustrating it is when you're in the middle of a titration and your burette decides to crack? We've all been there.
Our borosilicate glass equipment is built to handle the daily grind of real lab work - from routine analyses to those marathon synthesis sessions that run past midnight.

Look, you need glassware that won't let you down when you're running samples or teaching undergrads who think "thermal shock" is just a suggestion. Everything here meets DIN/ISO standards because your results matter, and nobody has time to repeat experiments because of subpar equipment.

Durable Laboratory Glassware Built for Demanding Applications

Borosilicate construction means you can go from ice bath to hot plate without holding your breath. The chemical resistance handles pretty much everything except HF and really angry alkalis - which honestly, if you're working with those, you've got bigger concerns than your beakers.

Class A accuracy certification isn't just paperwork. When you're doing volumetric work, those graduations need to be spot-on. You can cross-reference specs with our laboratory Equipment section if you need detailed tolerance ranges for specific applications.

Thermal Shock Resistance and Temperature Tolerances

Round-bottom flasks for reflux setups handle thermal cycling like champs. We're talking repeated heating and cooling without the spider-web cracks you'd get from regular soda-lime glass.

• Operating range: -70°C to +500°C for borosilicate glass
• Thermal shock resistance: Withstands temperature differentials up to 165°C
• Autoclavable at 121°C for sterilization cycles
• Compatible with hot plates, heating mantles, and open flames

Beakers in every size you actually need - 50mL for quick dilutions up to 2L for bulk preparations. Crystal-clear visibility means you can spot precipitation or color changes without squinting. They work great alongside Chemicals from our catalog when you're setting up standard solutions.

Precision-Graduated Volumetric Glassware

• Volumetric flasks with narrow necks for precise dilutions - autoclavable so you're not stuck hand-washing everything
• Graduated cylinders in sizes from 10mL to 2L, because sometimes you need flexibility over absolute precision
• Burettes with reinforced stopcocks that won't seize up after a few months (we've all fought those battles)
• Pipettes that pair well with items from our Bottles, jars and packaging catalog for sample transfer

Pro tip: Keep your volumetric gear separate from your general-use beakers. You'll thank yourself during audits. Class A tolerances are typically ±0.1% for volumetric flasks, which matters when you're preparing calibration standards or doing quantitative analysis.

Chemical Resistance Properties of Borosilicate Glass

Erlenmeyer flasks (yeah, we still call them conical flasks sometimes) have reinforced rims because chipped glassware is both dangerous and annoying to explain to procurement. Borosilicate glass resists attack from acids, neutral solutions, and most organic solvents - making it suitable for about 95% of lab procedures.

• Excellent resistance to mineral acids (HCl, H2SO4, HNO3)
• Handles organic solvents like acetone, ethanol, and chloroform without degradation
• Salt solutions and buffer systems won't etch or cloud the surface
• Avoid: hydrofluoric acid, hot concentrated phosphoric acid, strong alkalis above 80°C

Got distillation work? Flasks with ground-glass joints create proper seals for your apparatus. Check our dedicated section for specific joint sizes and configurations - trust me, you don't want to order the wrong taper. Standard tapers like 14/20, 19/22, and 24/40 ensure compatibility across your setup.

Test tubes with rim reinforcement are dishwasher and autoclave safe. Watch glasses for covering beakers during evaporation, funnels in various stem lengths because sometimes you need that extra reach, and Petri dishes that stack cleanly for storage round out the essentials.

Everything ships with certification docs, so you're covered for quality assurance and regulatory compliance. Browse the full Products catalog to see how these pieces fit into complete lab setups.
