EISCO Erlenmeyer Flask, 100mL – Borosilicate Glass
EISCO’s 100 mL Erlenmeyer combines moderate size with durable borosilicate glass. It features easy-to-read white enamel graduations every 25 mL, aiding quick measurements. Best for small-scale experiments, teaching labs, and general chemistry tasks where a basic, heat-tolerant flask is required.
Who this is best for: students and professionals needing a single, reliable 100 mL flask for routine mixing and heating. Why selected: strong glass with uniform wall thickness supports heating and thermal shocks. Limitation: lacks a neck joint or stopper, limiting certain setups.
EISCO 12PK Erlenmeyer Flasks, 100mL
This pack includes 12 borosilicate 100 mL Erlenmeyer flasks, suitable for classrooms and lab groups needing multiple vessels. Features identical 25 mL graduations and durable glass designed for chemical resistance and high-temperature use.
Who this is best for: labs or classrooms needing cost-per-flask efficiency and multiple vessels. Why selected: bulk pack reduces the need for frequent replacements. Limitation: bulk packaging may require inventory planning; no individual joint or stopper information provided.
QWORK Glass 100ml Single Neck Flat Bottom Flask
QWORK’s 100 mL flat-bottom flask features a 24/40 standard outer joint, enabling connection to compatible distillation equipment. The flat bottom supports stable standing for upright operations and easier sample handling in small setups.
Who this is best for: labs needing joint compatibility for distillation or glassware extensions. Why selected: dual-use function with standard joint, useful for more complex glassware configurations. Limitation: capacity is standard 100 mL, but some users may require a different joint size for specific apparatus.
XCD Erlenmeyer Flask 100ml with Stopper
XCD offers a 100 mL Erlenmeyer with a 24/40 joint and stopper, designed to minimize evaporation during mixing, heating, or titration tasks. The conical shape promotes vortex formation for mixing efficiency, aligning with common lab workflows.
Who this is best for: researchers needing good sealing and efficient mixing. Why selected: stopper reduces evaporation and maintains solution integrity. Limitation: clarify compatibility with specific sealing apparatus to avoid misfit.
QWORK Borosilicate 3.3 Flask Set
This set includes 50 mL, 100 mL, and 250 mL borosilicate 3.3 glass flasks with clear graduations and frosted stoppers for good sealing. High temperature and chemical resistance make it a versatile choice for varied experiments.
Who this is best for: bulk kit users needing a range of sizes, especially for progressive experiments or demonstrations. Why selected: broad size range and durable Borosilicate 3.3 glass. Limitation: stoppers are not interchangeable across all sizes, so plan accordingly.
Buying Guide: Key Purchase Considerations
- Goal of use: Decide whether you need a stand-alone flask, a jointed variant for distillation, or a sealed option for evaporation control.
- Material quality: Borosilicate 3.3 glass offers durability and heat resistance; confirm wall thickness if you plan frequent heating.
- Joint compatibility: If connecting to other glassware, check for 24/40 joints and available stoppers or adapters.
- Graduations and visibility: Choose clear, legible graduations for precise measurements in teaching or research tasks.
- Quantity needs: Bulk packs are economical for classrooms; individual flasks suit single-user labs requiring consistency.
- Sealing capability: If evaporation control is critical, seek flasks with stoppers or jointed seals designed for your protocol.
Frequently Asked Questions
- What is the advantage of borosilicate glass for flasks?
Borosilicate glass resists thermal shock and chemical corrosion, making it suitable for heating and reaction processes. - Do 24/40 joints fit all lab equipment?
Joints are standardized, but verify compatibility with your existing adapters or condensers before purchase. - Is a sealed stopper necessary for all 100 mL flasks?
Not always; use stoppers when evaporation control or containment is important for your procedure. - Should I buy a bulk pack or individual flasks?
Bulk packs reduce per-unit cost for classrooms or large groups, while individual flasks suit focused, consistent use. - Can these flasks be autoclaved?
Many borosilicate flasks tolerate autoclaving, but confirm specific model capabilities before autoclaving. - What should I consider for jointed glassware in small labs?
Ensure joint sizes align with your distillation or receiving apparatus to avoid leaks or poor connections.
