Cheap Beakers - High Quality:
Let me preface this by mentioning I only purchased these as a novel yet practical idea to serve drinks in at home, and have not been using them for any scientific means. However, they have been serving their purpose well, and are an excellent value as far as drinking glasses go. This funky solution makes an excellent conversation starter and these seem sturdy and well made. They have taken a couple drops (about 6 inches or so) to a countertop and have not yet chipped or broken and have been through the dishwasher dozens of times without the label or measurement marks fading or deteriorating in any way. The seller shipped my order promptly via USPS.

Currently this 250 ml glass beaker costs $2.65 on Amazon.

pH test kits | pH test papers

I really love science and doing all sorts of experiments and such.Today,Am writing a review on pH testing paper to be more specific,ColorpHast pH test strips.

So what to look for when buying a pH test strip?And what's so special about ColorpHast?

No more bleeding.
ColorpHast test strips have the dye covalently bound to the paper,That means the dye does not mix with the solution,thus keeping it a fair test.

Speed is important.
The test results of the pH appear in 3-5 seconds at it's most.No more waiting for results to appear.

Accuracy.
Results have to be accurate for the test to be fair and to get the right results,Results are accurate with a wide range of pH of 0-14.

Extra.
Also the paper can be used in weakly buffered/weakly colored solutions.

How many stars was it rated?
5 Stars out of 5 in Amazon.

What does a customer say?

Very reliable and accurate ph strips:
I have tried a lot of ph strips, and was recommended these by a friend. I am very pleased with the results - they are much more accurate than other brands I've tried, with many different ranges to choose from too. Despite the price I will be getting these from now on.
