Self-Contained Kit to Grade Pharmaceutical Solutions According to USP Color
The Comparator 2000+ is an easy-to-use, entry-level color measurement system that compares the color of the sample directly against the color of glass in a disc. All you need to do is rotate the disc to get the closest result to the scale.
- Everything You Need to Grade Pharmaceutical Solutions According to USP Color
This kit includes four color-grading discs, each containing stable-colored glass standards that represent a portion of the US Pharmacopoeia Color scale. The sample (in a 40 mm glass cell) is viewed in a Lovibond® Comparator 2000+ with the appropriate test disc until a color match is obtained.
- Fast, Economical & Portable Visual Matching
The Comparator 2000+ is a flexible, modular system for Visual Color Grading. Using a suitable comparator instrument and glass disc, you can quickly visually match the sample directly against the calibrated, color-stable glass standards.
- Two-Field Vision for Accurate Results
Lovibond® comparator instruments include an integrated prism that causes the sample and comparison fields to overlap, allowing enhanced color 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 color 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 standardized light source that guarantees you a constant lighting conditions for accurate color grading. This is particularly useful when the sample is very pale in color. By using a Lovibond® lighting unit, you can be confident of uniform lighting conditions for color matching, 24 hours a day and irrespective of ambient lighting.
- Supports Multiple Path Lengths
The standard Comparator 2000+ is a short path length instrument (up to 40 mm) to be used with relatively dark colors. Nessleriser systems are longer path length instruments to enable you to match a column of sample in a glass cylinder of appropriate path length. They are designed for measuring unsaturated samples that are below the sensitivity of the Comparator 2000.
The unique feature of Lovibond® test discs is that they incorporate colored glass standards that are color stable and not affected by UV light or extreme environmental conditions.
- One Instrument - 100's Discs
There are literally hundreds of glass discs available for you to choose from: ranging from the more standard scales such as the EBC (European Brewing Convention) scale to more obscure scales or even bespoke scales that we have made for customers. No challenge is too great.
- Integrated Kits for On-Site, Immediate Use
For several scales, we also provide integrated kits containing everything you need to start measuring straight from the box.
