Does what it should: Lab Chemicals

I was confident that my pH levels had increased by a few tenths and using this product confirmed that for me. I look forward to this product which will help me keep my readings accurate in the future. I will buy it again once my stock runs out. The vials were delivered safe and sound, sealed with foil under the caps to prevent leakage, but not difficult to open. This is my first purchase of a pH calibration solution so I have no comparison with it. Full Disclosure of Review: The Company offers…

Pros
  • Double Seal. Shelf life 2 years from date of manufacture for an unopened vial.
Cons
  • There are other interesting options.

Build trust and validate your measurements. This is good insurance

I have ordered a calibration kit with storage solution. The set was shipped quickly and well packaged and arrived within a few days. The presence of different colors in liquids makes work easier and reduces the possibility of errors. There are many solutions to my maintenance needs of a commercial pool surveillance system. The storage solution is also used for my ORP sensor. The pH 7.0 reference can also be used to test my Taylor Pool Daily Test Kit. The acid solution came with an extra foil…

Pros
  • color coded for quick identification.
Cons
  • A small change

Solution 4.0 is bad.

I've had something like this before and it worked fine, but I noticed something was wrong with the 4.0 solution when I started getting calibration errors. I have an expensive Bluelab stylus so they don't have this type of problem but I bought a replacement thinking it was a stylus but it wasn't. I got a replacement grip but still had errors with my 4.0 solution. Then I noticed something was floating in my 4.0 solution bottle when I was only a few months old, but 7.0 was still fine. So I thought

Pros
  • Manufactured in an ISO 9001:2015 certified facility using high purity reagents, deionized water and certified analytical balances in a temperature controlled environment.
Cons
  • High price
