This unit uses a lens and mask to mask the beam that passes through the integrating sphere opening. The minimum beam diameter is about 1 mm. It requires a sample base plate integrating sphere unit at the same time. Note: For UV-2600 series, MPC-2600A and BIS-3100 sample base plate integrating sphere set is separately required. […]
This large-sample compartment enables transmission and reflection measurements of various-shaped samples.
The transmittance of thin samples such as film with little scattering can be measured by combining the film holder with the standard sample compartment. The transmittance of thick samples that cause scattering can also be measured by using an integrating sphere. For UVmini,UV-1280/1800/1900 series/2600 series/2700 series/3600/3600Plus series, SolidSpec series * When used on the UVmini […]
With absolute specular reflectance measurement, as shown in the figure, a reference sample is not used, the sample-free state (air) is set at 100%, and the reflection of the sample is simply applied to the 100% setting when measuring the sample.
With relative specular reflectance measurement, the reflectance is calculated from the strength ratio after comparing the light reflected from the reference sample with the light reflected from the measurement sample. As shown in the figure, the reflectance of the reference sample is taken to be 100%, and the reflectance of the sample with respect to […]
The following accessories are used to continuously supply samples to a sample compartment for measurement. The sipper unit automatically supplies sample solutions to cells using a stepping motor-driven peristaltic pump. When this unit and the auto-sample chamber are used together, up to 100 samples can be measured automatically and continuously. For UVmini,UV-1280/1800/1900series/2600series/2700series/3600/3600Plus series *) This […]
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
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.
When the concentration of the sample is too low to be measured using a standard cell with an optical path length of 10 mm, a cell with a longer optical path length is used to enable measurement at the optimum absorption sensitivity. As shown in the figure, the absorption spectrum of potassium permanganate becomes clearer […]
Multicell Sample Compartment (6 Cells) This compartment is a cell positioner that can hold up to six sample cells at a time. It has no temperature control capability. ■ For UVmini, UV-1280/UV-1800/1900/2600/2700/3600/3600Plus series *) Cells are not included in the standard package. Please purchase separately.
