AF267 Cholinesterase Test Kit

Monitor Exposure to Organic Phosphorus Insecticides Mark as favourite

Part Number 412670


  • Fast, Economical & Portable Visual Matching
  • Two-Field Vision for Accurate Results
  • Ability to Guarantee Constant Lighting Conditions

The Comparator 2000+ is an easy-to-use, entry level colour measurement system that compares the colour of the sample directly against the colour of glass in a disc. All you need to do is rotate the disc to get the closest result to the scale.


  • Medical and Clinical Products
  • Rapid Field-Testing of Exposure to Organic Phosphorus Insecticide
    The Lovibond® Cholinesterase Test Kit is designed to alert you (farmers, spray operators, research workers) of these insecticide chemicals and any absorption and unsafe working practices. It is particularly useful for emergency use or away from the laboratory. The kit is provided with 200 lancets, and enough reagent for approximately 10,000 tests.
    The kit is specified by the World Health Organisation in its technical information sheet No 356, 1967.
  • Fast, Economical & Portable Visual Matching
    The Comparator 2000+ is a flexible, modular system for Visual Colour Grading. Using a suitable comparator instrument and glass disc, you can quickly visually match the sample directly against the calibrated, colour stable glass standards.
  • Two-Field Vision for Accurate Results
    Lovibond® comparator instruments include an integrated prism which causes the sample and comparison fields to overlap, allowing enhanced colour discrimination and matching. The prism is ultrasonically sealed to prevent contamination of the optics. Each individually graded glass standard represents a discrete step on the measurement range (as opposed to a continuous graduation), aiding colour discrimination and allowing great accuracy of results.
  • Ability to Guarantee Constant Lighting Conditions
    An optional item for the Comparator 2000+ is the Daylight 2000 Lighting Unit. This is a standardised light source which guarantees you a constant lighting condition for accurate colour grading. This is particularly useful when the sample is very pale in colour. By using a Lovibond® lighting unit, you can confident of uniform lighting conditions for colour matching, 24 hours a day and irrespective of ambient lighting.
  • Extended Shelf Life
    The unique feature of Lovibond® test discs is that they incorporate coloured glass standards that are colour stable and not affected by UV light or extreme environmental conditions.
    Please note, we cannot guarantee compatability of discontinued Lovibond® Comparator 1000 disks with the Lovibond® 2000+ Comparator.
