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, thesample compartment unitis 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, thesample compartment unitis 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 10mm 100µL
5mm 50µL
16 series micro multi-cell 10mm 100µL
5mm 50µL
*) To use the micro multi-cell, the 8/16 series micro multi-cell holder is required.
