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.
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 registed 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.
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.
