Temperature Controlled Accessories:
Water Circulated Cell Holder 
(available with or without stirring):
Allows measuring samples at controlled temperature between 5 and 60°C. Stirring is available for added temperature uniformity within the sample. Stirring speed is indenpendently adjustable from the front panel, between 500 and 1200 rpm. A dry air port is available to eliminate condensation when measuring below ambient temperature. (Requires a heated water circulator)
Programmable Thermoelectric Cell Holder with Stirring:
Used for thermostatting samples at a fixed or programmable variable temperature in the range of 0 to 100° C (in steps of 0.1°C). Temperature is controlled by a Peltier device for fast heating of the sample. Temperature accuracy is ±2°C. Requires an ambient water circulator for cooling. Includes a dry port to control condensation. A cell cap is included to avoid evaporation when working at temperatures above ambient.
QNW Peltier Cell Holder with Stirring:
Includes a single temperature controller with a range of -10.00 to +105.00°C (±0.02°C). The lower limit could be extended down to about -40°C by ordering p/n AN0-9357 Windowed Jacket and Cap.
Dry gas purge may be used to reduce condensation when working at low temperature. It includes an ambient water circulator, required for removing heat from the Peltier during the cooling cycle. Includes SER 2.X Serial Interface, signal cable and computer program for external PC control which adds temperature ramping capability Includes built-in filter holders
Heated Water Circulator:
4 lt capacity stainless steel tank, temperature range: 25 to 120°C (20 to 120°C with water cooling), temperature control: ±0.02C. It includes a cooling coil for rapid cooling using tap water circulation.
Compatible with water circulated temperature controlled sampling accessories.
Ambient Water Circulator:
Ambient water circulator for use with thermoelectric accessories requiring cooling.
Note: This accessory is not intended to provide temperature control, but only water circulation at ambient temperature, to help Peltier controlled accessories speed up the cooling cycle
Low Temperature Sample Compartment:
Used for measuring fluorescence or phosphorescence of solutions frozen to a liquid nitrogen temperature of -196ºC (77ºK). It replaces the standard sample compartment. Includes a built-in filter holder, liquid nitrogen dewar flask and four quartz sample tubes (two 5mm and two 8mm diameter tubes). NOTE: The sovent used must be water-free. EPA (ethyl-ether, iso-pentane, ethanol=5:5:2) is recommended.
Cell Changers
Manual 4-position Ambient Cell changer:
Accomodates four 10mm square cells (not included) and replaces the standard sample compartment. The cell position is selected by a control at the front of the sample compartment.
Manual 8-position Non-thermostatted Cell changer:
Accomodates eight 10mm square cells, or 10mm and 12mm OD test tubes that are less than 105mm tall (not included). It replaces the standard sample compartment.
Cell position is selected by control at the front of the sample compartment.
Sampling Accessories
Absorption Cell Holder:
Allow measuring transmisson data for a sample and blank. Using built-in data processing functions in FL Solutions, it calculates percent transmission (%T) of the sample. This data is exported to Excel to calculate absorbance. It is useful for determination of Relative Quantum Efficiency of liquid samples.
High Sensitivity Cell Holder:
Utilizes concave mirrors positioned immediately behind the excitation and emission beam paths to improve sensitivity by 2X. Accomodates a 10mm square cell (not included) and is mounted on the base of the standard sample compartment.
Solid Sample Holder:
For measuring solid samples up to 30mm thick such as plastic, paper, cloth, thin films, fibers, powders and highly concentrated solutions in a cuvette. Front face geometry is used with the excitation light beam incident to the sample at a 30 degree angle. This geometry eliminates the entrance of excitation reflected light into the detector. Includes one non-thermostatted powder holder which is mounted on the base of the standard sample compartment.
Attenuator Filter Set:
Neutral density screens which pass all wavelengths from 200 to 900 nm. The set consists of one each 4%, 8%, 11%, 15%, 23% and 33%T screens. A filter holder is included. NOTE: Neutral density screens reduce the excitation light when narrow slits are not available. In a variable band pass instrument, screens are useful for adjusting the relative intensity to a desirable Y-scale position for a set of samples. Decreasing the slit width however results in a higher reduction in intensity than the addition of a screen.
Cutoff Filter set:
Consist of five 2x2 inch polished glass cutoff filters and a filter holder. The filters are as follows: WG-295 passes wavelengths longer than 295nm, WG-32 passes wavelengths longer than 320nm, L-37 passes wavelengths longer than 370nm, GG-39 passes wavelengths longer than 395nm, L-42 passes wavelengths longer than 420nm

Intacellular Ca++ measurement accessory:
An IC applications system designed for instrument paramater setup, collection of data from both the excitation and emission spectra, and measurement and calculation of intracellular calcium concentrations using single or ratio probes. Two ratios can be performed simultaneously. All data could be saved for further analysis. Raw data, ratio and concentration data can be converted. Post run processing functions include smoothing, deletion of artifact points due to technique, graph subtraction, background subtraction and calculation of concentrations using the Grynkiewicz equation. Fmin and Fmax values are selectable from the new data graph or can be entered manually. A calibration curve can be generated from the raw data or ratios and applied to concentration calculations.
