Have you considered your servicing requirements? Much like a car, scientific instruments may need a bit of care to keep them working reliably and at their most accurate.
The Camlab Service Department have over 60 years experience in scientific instrumentation. We have a number of highly qualified internal and field-based service engineers able to perform a variety of jobs including preventative maintenance servicing and calibration.
Camlab can offer yearly service contracts which include two main types of preventative maintenance/calibration services – the back to base service and an engineer visit to your site. These options are can be offered with differing turn around times depending on the instrument type and your requirements along with loan instruments if available.
A typical preventative maintenance service includes the following:
Inspection and testing of the unit
Dismantling, cleaning and inspection of the key parts
Correction of minor defects including adjustments if necessary
Reassembly and testing
Take post adjustment / cleaning readings
Supply of calibration certificate
Return of the item to you (back to base services)

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.
When selecting filter paper, these parameters should be taken into consideration.
|Ash content/residue on ignition||The ash content is determined in accordance with DIN 54370. To obtain this 10 g filter paper is weighed before and after ignition in a platinum crucible at 800 °C. The results are expressed as % of original paper weight.|
|Dry bursting strength||For determination of the dry bursting strength the paper is clamped over a rubber diaphragm with
an area of 10 cm2. The strain on the paper is then increased by applying an increasing air pressure,
until the paper bursts. The dry bursting strength in accordance with DIN 53113 is stated in KPa.
|Tensile strength||For determination of the tensile strength, a paper strip (measuring 180 x 15 mm) is subjected to vertical strain by applying increasing weight. The force expended at the moment of tearing represents
the tensile strength. Results are expressed in N/15 mm.
|Thickness||The thickness of a paper is measured with a touch pressure device. Especially for soft and creped
papers it is important that the touch pressure is not too high. Otherwise, the papers are compressed
and a falsely low thickness is obtained.
|Filtration speed||For determination of the filtration speed in accordance with DIN 53137 the duration of flow of 10 mL distilled water through a quadrant-folded, freely suspended filter circle of 12.5 cm diameter is measured. Results are expressed in seconds.|
|Basis weight||The basis weight is determined for a sample of 10 x 10 cm. It is measured in g/m2.|
|Gurley test||The Gurley test measures the time required for filtration of 100 mL air at a water column pressure of 31 mm. The sample has an area of ¼ sq. inch.|
|Wet strength||The wet strength of a paper is a measure for the mechanical stability of a paper in a wet or moist condition. For example, it can be determined as the tensile strength or the bursting strength (see above).|
The retention efficiency of a filter paper is influenced by several factors. Since filter papers are deep bed filters, one usually refers to a mean particle retention.
|Capillary rise according to Klemm||The capillary rise according to Klemm indicates how far a strip of filter paper is moistened in 10 min when vertically dipped with one end into distilled water (20 °C).|
|Particle retention||Particle retention refers to the efficiency of filter papers in retaining certain precipitates. It is characterized by the permeability of the paper for precipitates of iron(III) oxyhydrate, lead sulfate, calcium oxalate and barium sulfate.|
