United Scientific™ FG5340-1000 Laboratory Grade Borosilicate Glass Heavy Wall Filtering Flask, Bolt Neck with Tubulation, 1000ml (1 Liter) Capacity

Worked really well, seems to be heavy built.

I haven't used it yet because I need tubing but the flask looks to be of good quality, with thick walls and no damage occured in transit.

Works as it should no complaints

Good price for a heavy walled 1 liter flask. Works great with a 500 ml Buchner funnel. Using car vacuum hose, I used the system with the following pump sold on Amazon: HSH-Flo "12V/24VDC 6W 8L/min 120Kpa". For the power supply, I used an old 12 volt adapter I had from an obsolete internet modem.

The one I purchased 2 years ago was thicker and heavier, by far, than the 2 I received this order. I re-ordered because I liked my first one until I broke the line connector. These 2 not only seem thinner, but they are lighter in mass. The vacuum inlet are 2 different sizes, not even close. Looks like they cheapened the quality. I will return for a replacement. I will edit once I receive it.

Other then that its a beaker

Even though it says borosilicate glass its got to be a lower quality one. But for the price you can't really complain. I've used it for acids and very little issue with it

Flask was as ordered and in excellent condition. The packaging was off the charts, and some of the best I’ve ever seen, Thank You
