Micro-Volume Measurement

Spectra of Herring Spermatozoa (a) and Bovine Serum-Albumin (b)

The following accessories are used to measure micro-volume samples. The figure shows the absorption spectrum obtained by measuring spectra of 50 μL herring spermatozoa (a) and bovine serum-albumin (b) using a super-micro cell holder and cell. Spectra with good S/N ratios can be obtained even in the ultraviolet region.

 
Super-Micro Cell Holder

This holder holds micro or super-micro cells for the measurement of extremely small-volume samples such as DNA and protein. The minimum required sample volume is 50 µL. Cells of different bottom thicknesses can be accommodated since the height of the cell bottom can be adjusted.

  • For UVmini series, UV-1800/2450/2550/2600/2700/3600 and SolidSpec
  • When used on the UVmini series, the sample compartment unit is required. Also, the minimum required sample volume is 100 µL.
Super-Micro Cell Holder

This holder is required when using semi-micro cells and micro cells. (The mask width can be adjusted.)

  • For UVmini series, UV-1800/2450/2550/2600/2700/3600 and SolidSpec
  • When using a semi-micro cell with an optical path width of 4 mm on the UV-1800, this accessory is not required; measurement is possible with the standard cell holder.
  • On the UVmini series, only a semi-micro cell with an optical path width of 4 mm can be used.
  • When used on the UVmini series, the sample compartment unit is required.
8/16 Series Micro Multi-Cell Holder MMC-1600/1600C

This holder holds a micro multi-cell, either 8- or 16-cell, for micro-volume measurement. Two types are available: the normal-temperature type (MMC-1600) and the constant-temperature water-circulation type (MMC-1600C). Choose the cell according to the required model as follows:

  • For UV-1800/2450/2550/2600/2700/3600
8/16 Series Micro Multi-Cells

Two types of micro multi-cells, minimum sample amount of 50 µL and 100 µL, are available for the 8 series and 16 series.

Type Optical Path Length Cell Volume
8 series micro multi-cell 10 mm 100 µL
5 mm 50 µL
16 series micro multi-cell 10 mm 100 µL
5 mm 50 µL

*) To use the micro multi-cell, the 8/16 series micro multi-cell holder is required.

For Research Use Only. Not for use in diagnostic procedures.
