Let’s Dive into UNICO 1100RSE Spectrophotometer 10nm Bandpass, Preset 220V
The UNICO 1100RSE Spectrophotometer 10nm Bandpass, Preset 220V is a workhorse of the analytical lab, built by UNICO to provide reliable spectrophotometric measurements in a variety of settings. It’s a single-beam instrument, operating in the 335-1000 nm range, and designed for labs needing absorbance, transmittance, concentration, and factor measurements without breaking the bank.
My introduction to spectrophotometry came early in my career, testing water samples for contamination in remote field labs. Back then, a rugged and dependable instrument was paramount, so my interest was immediately piqued upon encountering the UNICO 1100RSE. The ability to quickly and accurately quantify substances in a sample can be crucial, whether assessing water quality or verifying the purity of a compound.
The UNICO 1100RSE arrived securely packaged, containing the instrument, a power cord (preset for 220V), an operation manual, 12 round optical glass cuvets, a square cuvet adapter, and a dust cover. The initial impression was that of a solid, well-built piece of equipment, not overly flashy but designed for functionality.
Compared to the more advanced double-beam spectrophotometers I’ve used in the past (like the PerkinElmer Lambda series), the UNICO 1100RSE trades some sophistication for simplicity and affordability. I had also considered the Thermo Scientific GENESYS 10S, but the UNICO model seemed to offer a more straightforward interface for basic quantitative analyses. Its single-beam design necessitates more frequent blanking, but the UNICO 1100RSE’s ease of use and rugged construction ultimately won me over.
My initial impression was cautiously optimistic. While I missed some of the advanced features of higher-end spectrophotometers, the UNICO 1100RSE Spectrophotometer promised to deliver reliable results in a user-friendly package at a reasonable price point.
Real-World Testing: Putting UNICO 1100RSE Spectrophotometer 10nm Bandpass, Preset 220V to the Test
First Use Experience
I first tested the UNICO 1100RSE in my moderately equipped analytical testing lab. The lab experiences temperature fluctuations, and occasionally deals with dust from nearby material processing operations.
The initial setup was straightforward: plug in the power, allow the tungsten halogen lamp to warm up, and run a wavelength calibration check using known standards. The auto-zero function and one-touch blanking made it easy to standardize the instrument before each set of measurements.
After the initial setup, measurements were easily conducted and provided fast results after entering a sample. During one session, I accidentally splashed a small amount of solution on the instrument housing. Luckily, it was easy to wipe clean, due to the smooth external surfaces.
Extended Use & Reliability
After several months of consistent use, the UNICO 1100RSE Spectrophotometer has proven to be a reliable workhorse. There are no signs of wear and tear on the unit.
Cleaning is a breeze with a simple wipe-down, and the tungsten halogen lamp has yet to require replacement despite hours of use. Compared to older spectrophotometers I’ve used that required frequent recalibration and lamp replacements, the UNICO 1100RSE has been remarkably stable and low-maintenance.
Breaking Down the Features of UNICO 1100RSE Spectrophotometer 10nm Bandpass, Preset 220V
Specifications
The UNICO 1100RSE Spectrophotometer 10nm Bandpass, Preset 220V boasts the following key specifications:
- Bandpass: 10 nm. This defines the spectral resolution of the instrument; a wider bandpass means less resolution, but potentially higher light throughput.
- Monochromator: Single Beam, Grating System 1200 lines/mm. This setup disperses light into its constituent wavelengths, allowing for selection of the desired wavelength.
- Wavelength Range: 335-1000 nm. This covers the UV-Visible spectrum, making it suitable for a wide range of applications.
- Wavelength Accuracy: ±2 nm. This specifies the allowable error in the selected wavelength.
- Wavelength Repeatability: ±1 nm. This indicates the consistency of wavelength selection across multiple measurements.
- Stray Light: < 0.5%T at 340 & 400 nm. Stray light is unwanted light reaching the detector, and this value represents a low level of interference.
- Photometric Range: 0-125%T 0-2A 0-1999C (0-1999F). This defines the instrument’s measurement capabilities in terms of Transmittance (%T), Absorbance (A), Concentration (C), and Factor (F).
- Photometric Accuracy: ± 1.0T%. This specifies the allowable error in the transmittance measurement.
- Data Output: RS232C. This provides a standard serial port for data transfer to a computer.
- Application Software: Unico SS-1.11. This software allows for data acquisition and analysis.
- Light Source: Tungsten Halogen Lamp. This provides a stable and broad-spectrum light source for measurements in the visible range.
- Power Requirements: 230V/60Hz switchable, preset 220V. This indicates the power supply requirements.
- Size: 16.1 x 12.1 x 7.1 inch (408 x 308 x 185 mm). These are the physical dimensions of the instrument.
- Weight: 13.2 lbs (6 kg). This is the weight of the instrument.
These specifications define the capabilities and limitations of the UNICO 1100RSE. The 10nm bandpass, while adequate for many routine analyses, may limit its use in applications requiring high spectral resolution.
