Breaking Down the Features of UNICO Tungsten-halogen Lamps, Package Of 1 S-1200-505
Specifications
The UNICO Tungsten-halogen Lamps, Package Of 1 S-1200-505 is a single, tungsten-halogen bulb designed specifically for UNICO spectrophotometers. Its primary specification is its role as the light source for spectral analysis, emitting a broad spectrum of visible and near-infrared light. The bulb typically operates at a specified voltage and wattage, crucial for providing the correct energy output for the spectrophotometer’s detection systems.
This type of lamp is known for its excellent color rendering and stable light output, which are critical for accurate quantitative measurements in spectrophotometry. The tungsten filament, heated to incandescence, produces a continuous spectrum that mimics daylight, making it ideal for measuring absorbance across a wide range of wavelengths. The specified model number, S-1200-505, ensures compatibility and proper fit within compatible UNICO spectrophotometer models.
When compared to other light sources like deuterium lamps (used for UV wavelengths), tungsten-halogen lamps cover the visible spectrum effectively. This means that for analyses requiring only visible light, this lamp provides a cost-effective and dependable solution. The included package size of “Package Of 1” means users are purchasing a single replacement unit, which is typical for such specialized components, allowing for targeted replacement without excess inventory.
Performance & Functionality
The core function of the UNICO Tungsten-halogen Lamp is to provide a stable and consistent light source for spectrophotometric measurements. In this regard, it performs exceptionally well. The light emitted is uniform across the intended spectrum, which is paramount for achieving accurate absorbance readings.
Its primary strength lies in its consistent spectral output over extended periods. This stability directly translates into reliable and reproducible analytical results, which is the ultimate goal in any laboratory setting. Weaknesses are hard to identify in such a specialized component when it performs as intended; its function is rather binary – it either works, or it doesn’t, and provides the necessary light.
Considering its price point of $55.99, the performance it delivers meets and often exceeds expectations for a component designed for long-term use in critical analytical instrumentation. It fulfills its purpose flawlessly, enabling precise spectrophotometric analysis without introducing significant error from the light source itself.
Design & Ergonomics
The design of the UNICO Tungsten-halogen Lamp is dictated by its function as a replacement bulb for laboratory instrumentation. It features a standard glass envelope that houses the tungsten filament and halogen gas mixture. The base of the lamp is designed for a secure and precise fit into the spectrophotometer’s lamp housing, ensuring proper alignment for optimal light path.
Build quality is evident in the sturdy construction of the glass envelope and the filament’s secure mounting. This attention to detail is important, as vibrations or poor filament stability can affect spectral readings. While ergonomics aren’t a primary concern for a component that remains sealed within an instrument, the design prioritizes robustness and efficient light emission.
Practical design details include the clear glass envelope, allowing for maximum light transmission, and the specific base type that ensures it locks securely into place. This prevents accidental dislodging and maintains the critical alignment required for accurate measurements. The bulb’s physical dimensions are engineered to fit specific UNICO spectrophotometer models, ensuring a seamless integration.
Durability & Maintenance
As a specialized component for laboratory equipment, the UNICO Tungsten-halogen Lamp is designed for a significant operational lifespan, typically measured in thousands of hours of use. Under normal laboratory conditions, where the instrument is powered on and off predictably and not subjected to physical shock, it is expected to last for several years.
Maintenance for this lamp is essentially non-existent beyond careful installation and ensuring the surrounding instrument is clean. The halogen cycle within the bulb helps to redeposit evaporated tungsten onto the filament, contributing to its longevity and consistent output. Unlike more disposable items, these bulbs are designed for sustained performance.
Potential failure points, while rare with quality manufacturing, could include filament breakage due to extreme physical shock or premature burnout if operated outside specified voltage parameters. However, in the context of its intended use within a controlled laboratory environment, the likelihood of such failures is minimal.
Accessories and Customization Options
The UNICO Tungsten-halogen Lamps, Package Of 1 S-1200-505 is typically sold as a standalone replacement part, meaning it does not come with accessories in the traditional sense. Its primary purpose is to function as the light source within a compatible UNICO Spectrophotometer. Therefore, there are no inherent customization options for the lamp itself.
The “customization” aspect comes into play when selecting the correct model number for your specific spectrophotometer. Ensuring you have the S-1200-505 model, or the manufacturer-recommended equivalent, is crucial for proper integration and optimal performance. This ensures it works seamlessly with the instrument’s optics and electronics.
Compatibility with other brands is generally not a factor; these are proprietary replacement lamps. For optimal results and to maintain instrument warranty, using the specified UNICO part is always recommended. The value lies in its direct fit and guaranteed compatibility, eliminating the guesswork associated with generic alternatives.
