What is an Erlenmeyer flask?

Erlemeyer flasks have that iconic narrow neck over a conical shaped body and a flat bottom. PYREX^® Erlenmeyer flasks have white enamel measurement marks along the side. The rim is traditionally heavy duty, to avoid chipping as much as possible.

Quality is always uniform across orders and flask sizes. So your 50ml Erlenmeyer flask and your 50ml flask, all the way up to your 2000ml erlenmeyer flask and beyond, always perform predictably in your lab.

What is an Erlenmeter flask used for?

The cone shape helps reduce losses from evaporation, and helps prevent spills while stirring liquid. They are typically used for:

• Holding
• Mixing
• Heating
• Cooling
• Incubation
• Filtration
• Storage

PYREX^® Erlenmeyer Flask Shipping FAQ

Q: Do you offer same day shipping on all PYREX^® flasks?

A: Absolutely! Place your order by 3:30 p.m. (Eastern Time Zone) and your order will ship the same afternoon.

Q: What is the Weber Scientific 1-2-3 Day Delivery Program? And does it apply to my Pyrex Erlenmeyer flask order?

A: When you order from Weber Scientific we will route your order so that all (or part) of it arrives at your facility within 1, 2 or 3 business days. Any upgrade in the level of service over basic UPS ground service will be done at our expense – not yours! Combined with our existing Same Day Shipping Pledge, this expedited routing program will insure prompt delivery to any location in the Continental U.S. – all at no extra cost.

To shorten delivery times even further an inventory of large volume products ship out of our Nevada warehouse for delivery to Western states and out of our Missouri warehouse for selected Southern and Midwestern states.

Q: How does the 1-2-3 Day Delivery Program work?

A: Place your order by 3:30 p.m. EST and your order will ship that afternoon. Your order will be routed via basic UPS or FedEx service if delivery is scheduled at 3 business days or less. If the delivery schedule indicates more than 3 business days, we will upgrade your order to 3 day select service at no extra charge to you. You pay only for basic ground service.

Q: How can I calculate the total delivery days in the 1-2-3 Day Delivery Program?

A: Let’s say you are located in California and call in an order to us on a Thursday morning. We will give it to UPS later that afternoon. The first delivery day would be Friday, the second would be Monday (weekends don’t count), and Tuesday would be the third day. All of our Continental U.S. customers can now expect delivery from us in 3 days or less. In this example, by Tuesday- at the very latest. Many of you will continue to receive your orders within 1 or 2 days!
