Ionic Strength Adjustment Buffers (ISAB) are required to accurately measure ions with an ion selective electrode (ISE). Each ISAB has been specially formulated to allow the buffering of all samples and standards to the same Ionic Strength without interfering with the ion measurement. The ISABs will come in a 500ml leak-proof bottle with an inner seal. The addition of 2ml of ISAB per every 100ml of standard and sample is recommended, please get in touch with our tech support team support@Camlab.co.uk for help on your particular application.
The ionic strength of standards and samples are not the same thereby the ability of ions to freely move around varies from sample to sample. This means that the effective activity of ions will vary between these solutions. Ion selective electrodes work by sensing ion activity when ions come into contact with the sensor surface. To ensure that all ions in the solution have an equal probability of contacting the ISE the total ionic strength of all solutions should be equal (as close to as possible). This is achieved by adding a small volume of ISAB (Ionic Strength Adjustment Buffer) to a fixed volume of all standards and samples.
Can I buy chemicals as a private individual?
The majority of chemicals can be purchased by private individuals but there are a number of products which are restricted for a number of reasons. These include Hazardous chemicals, weapon and drug precursor chemicals and other restricted chemicals.
What's the process for buying Chemicals?
Business User - You should have an account with Camlab so we can verify your status, for online purchases you need to be registered on the website against that business account and logged in. For hazardous and restricted chemicals you may need to undergo an additional check. To facilitate this you should provide a company number when making a purchase. New companies or sole traders may need to provide additional proof of a trading business to ensure we can fulfil your delivery.
These checks may add to the delivery times for these items, The delivery time period will not start until the chemical check has been completed; for clarification please phone 01954233110
Private user - For the purchase of Non-Hazardous chemicals you should be a registered user of the website and be logged in to make these purchases.
Guest checkouts for hazardous or restricted chemicals will be cancelled and refunded.
Delivery to Home addresses?
Camlab use a specialist chemicals courier to deliver chemicals, they will not deliver any hazardous chemicals to a residential address. These must be sent to a business address.
Home office license scheme
We are currently unable to supply chemicals to people who possess a home office license for private individuals under that scheme.

Oxidation reduction potential (ORP) otherwise known as a REDOX potential measures an aqueous system’s capacity to either release or accept electrons from chemical reactions. When a system tends to accept electrons it is an oxidizing system. Conversely, when it tends to release electrons, it is a reducing system. Like pH, it is not a measure of a concentration directly, but of an activity level....
The TRUEscience team have had years of experience in supporting users of traditional pH meters. During this time they saw all the frustrations that people have when using these meters - unclear buttons, difficult interfaces, trouble saving and retrieving results. They wanted to create a new and unique way of measuring pH that makes the test quick and simple while still retaining a high level...
One of the key user frustrations the TRUEscience team came across whilst developing the TRUEscience pH meter was how cluttered it was to have wires going across the lab bench from the meter to electrode and another for the temperature probe. Not only untidy, but you have to hold both of these in the sample at the same time as well as taking a reading on the meter with the other. TRUEscience ...
We were excited to hear about the logging capabilities of the The system works by the pH smart cap taking the pH and temperature readings and relaying this to an android device. The App on the device expands measuring capabilities, connecting to the cloud and allowing the creation more enriched readings. Add images, attach GPS location, write notes and organise readings into jobs, the TRUEs...
Traditional glass pH electrodes are very delicate and need regular care to keep them in good working order. If your electrode has been damaged by exposure to incompatible chemicals such as proteins, heavy metals or sulphides, you may be able to clean and revive it using specialized cleaning solutions...
