Coloromat 100 – Spectrophotometer for Color Measurement
The Coloromat allows an easy and reliable color measurement of liquids. The Coloromat is equipped with a continuous measuring mode with free configurable sampling rate for monitoring color changes in product streams. Transmission, extinction, and ICUMSA liquid color units at the recommended standard wavelength 420 nm are standard with this product.
Features
- Measurement of transmission/extinction
- Color determination of liquid samples
- Up to nine fixed wavelengths
- Polarimeter tubes up to 100 mm
- Integrated ICUMSA methods
Easy to Use
The touch screen is used for soft key functions and alphanumerical inputs which allow easy handling for example batch name, user etc. The wavelengths are selected via the touch screen. Three wavelengths are pre-installed as standards, optional the Coloromat 100 can be equipped with six further customized wavelengths. This opens a wide range of applications.
Due to the generous dimensions of the sample chamber, the use of polarimeter flow through tubes up to 100 mm as standard cuvettes allows easy filling and a high through-put. A 100 mm tube provides ten times better measurement accuracy and resolution compared to a 10 mm cuvette.
The sample compartment is open to the top and the bottom preventing spillage from entering the unit. Due to its unique optical design, the Coloromat is not affected by stray light. The Coloromat 100 is equipped with a continuous measuring mode with free configurable sampling rate for monitoring color changes in product streams as a function of time.
The general operating software contained in the FLASH MEMORY can be updated by PC (data file downloaded from Internet) and has a capacity for 250 pre-programmed tests. Up to 230 tests can be stored in the RAM. The import of data by touch screen or PC are possible.
Applications
- Enzymatic determination
- Color measurement of liquid crystal sugar (ICUMSA)
- Color index determination of beverages, e.g. soft drinks, wine, etc.
- Determination of the color of extracts (coffee, and many more)
- Color measurement of beer and wort (EBC color number)
- Biochromate measurements
- Multi-standard methods
- Simple extinction measurements
- Monitoring of time-dependent color changes
