For easy and fast measurements
Using NANOCOLOR® bar coded test tubes, the measurement is automatically performed after inserting the cuvette into the cuvette slot. The contact with any dangerous chemicals is avoided because the measurement is performed directly in the test tube. This guarantees maximum safety for the user.

Approved

Reliable and comparable results

The reaction basis of NANOCOLOR® tests is based on international approved standard methods like DIN-, EN-, ISO-, EPA- and APHA.

Precise

Easy handling and highest accuracy

All NANOCOLOR® tests contain accurate predosed reagents, that are directly ready to use and calibrated accessories.

Versatile

The perfect test for every request

For all important parameters in water and wastewater analysis, a large number of tests with different ranges is available.

Unique

No mix up of tests Every

NANOCOLOR® test box is equipped with a colour coded label and can be identified clearly by its colour.

A full overview of all reagents and equipment can be found in the NANOCOLOR Analysis System Brochure.

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.

Are Camlab chemicals suitable for clinical or other medicinal use?
Camlab supply chemicals for laboratory use only, they are not suitable or recommended for any other use.

Are Camlab chemicals suitable for food use?
Camlab supply chemicals for laboratory use only, they are not suitable or recommended for food use.

Sample Preservation

The sample should be thoroughly mixed or homogenized in a blender to be as representative as possible for the COD of the water to be examined.
COD determinations should be performed as soon as possible after sampling. If this is not possible, the pH should be reduced to 2 or less by the addition of 2 mL of concentrated sulphuric acid H₂SO₄ per 1 L of sample.
Storage of the acidified sample at room temperature: Analysis within 7 days.
Storage of the acidified sample at 4 °C: Analysis within 28 days. 

Decomposition

Rapid decomposition is not possible for all COD tests. Depending on the composition of the test, the water content can be higher. This results in a higher vapour pressure during the decomposition and increases the risk for bursting of the test tube. For more information about decomposition, please see the respective instruction leaflet.

Background Information 

PHP (potassium hydrogen phthalate) is used as a reference substance.

NANOCOLOR COD tube tests have advantages over the German norm DIN 38409-H41 in terms of use of toxic chemical compounds and user-friendly handling. Furthermore, seven NANOCOLOR COD tests meet the requirements of the DIN ISO 15705:2002 standard.

Filtration

For cumulative parameters, the sample must not be filtered prior to decomposition! By filtration, compounds which are poorly soluble are removed. Those compounds would thereby escape the detection which would lead to wrong results.

For a determination of dissolved COD, filtration of turbid samples using the membrane filtration kit 0.45 µm (REF 91650 / 91652) or glass fibre paper MN 85/90 BF is recommended. These filters are tested and validated specifically for this purpose.

Seawater suitability

Seawater analysis is generally not possible because of chloride interferences.
