Constant-Temperature Measurement

Measurement of ALP Enzyme Activity

Measurement of ALP Enzyme Activity



The following accessories are used for biological component measurement, enzymatic activity measurement and reaction rate analysis for which the sample must be kept at a constant temperature.

Instrument: UV-2600 + CPS-100
Substrate: 0.1 mM
Enzyme: 0 - 0.05U
Temperature: 37 °C
Detection Wavelength: 420 nm

CPS-100 6-Cell Thermoelectrically Temperature-Controlled Cell Positioner

CPS-100 6-Cell Thermoelectrically Temperature-Controlled Cell Positioner

These six-cell positioners permit measurement of up to six sample cells under constant-temperature conditions. When used in the kinetics mode, a system can be configured to measure enzyme activity in up to six samples maintained at a constant temperature.

■ For UVmini-1240 series, UV-1800/1900/2600/2700/3600 Series

*) Square cells are not included in the standard package.
Please purchase separately.
*) When used with the UV-1800/1900/2600/2700, a USB adapter CPS is required.

 

TCC-100 Thermoelectrically Temperature Controlled Cell Holder

TCC-100 Thermoelectrically Temperature Controlled Cell Holder

An easy-to-use constant-temperature cell holder that uses a Peltier element for electronic cooling. It does not require an external thermostatic bath or water for cooling.

■ For UVmini-1240 series, UV-1280/1800/1900/2600/2700/3600 Series

*) Square cells are not included in the standard package.
Please purchase separately.

 

Constant-Temperature Cell Holder

Constant-Temperature Cell Holder

This holder holds the sample cell at the desired, uniform temperature by circulating constant-temperature water. It accepts a pair of 10 mm square cells.

■ For UVmini series, UV-1280/1800/1900/2450/2550/2600/2700/3600 Series

*) When used on the UVmini series, the sample compartment unit is required.

 

S-1700 Thermoelectric Single Cell Holder

S-1700 Thermoelectric Single Cell Holder

This cell holder enables setting of the temperature program to raise and lower the sample cell temperature. The thermoelectric system enables the sample temperature to be controlled between 0 and 110 °C. A stirrer is also provided to ensure uniform temperature distribution throughout the cell.

■ For UVmini series, UV-1800/1900/2450/2550/2600/2700/3600 Series

*) Temperature is not controlled on the reference side.
*) Cooling water circulation is required for cooling the Peltier element. Though tap water can be used for cooling, the following conditions must be satisfied to elicit the maximum performance of the instrument. Use of a commercially available constant-temperature water circulator is recommended.
  • Cooling water temperature: 20±2 °C
  • Flow rate: 4.8 L/min or more
*) Cells are not provided. The following 10 mm square cell with a stopper (made by Hellma) is required.

 

Type Optical Path Length Minimum Required Sample Volume
110-QS-10 10 mm 3.5 mL
115B-QS-10 10 mm 400 µL
