JENWAY

Jenway is a British manufacturer of analytical instruments, primarily known for its range of spectrophotometers and associated laboratory equipment. Founded in the 1960s, the brand has established a reputation for producing reliable, benchtop instruments designed for routine colorimetric analysis, UV/Visible spectroscopy, and water quality testing. Jenway’s product portfolio includes visible and UV-visible spectrophotometers, colorimeters, flame photometers, and pH/conductivity meters, all built to meet the demands of industrial, educational, and research laboratories. The instruments are characterized by robust construction, often using ABS plastic housings, and offer wavelength ranges from 198 nm to 1,000 nm, with bandwidths typically between 5 nm and 8 nm, and accuracy specifications of ±2 nm. Many models include features such as dual cell holders, micro-volume accessories, and USB memory stick support for data transfer. Jenway spectrophotometers are designed for ease of use, with intuitive interfaces and minimal maintenance requirements, making them suitable for high-throughput environments. 3G Electric supplies a selection of Jenway spectrophotometers, including models like the 8305400, 8305601, 8305604, 8305602, 8305621, 8305622, 8305623, and 8305626. These units cover both visible-only and UV-visible configurations, with wavelength minima ranging from 198 nm to 335 nm and maxima from 800 nm to 1,000 nm. The instruments are compatible with various sample types, including reagents, ultra-micro cuvettes, AR grade chemicals, glass, and interchangeable accessories. Each unit is supplied with necessary accessories such as power adapters (with multiple plug types), cuvette holders, and universal power supplies. 3G Electric provides datasheets and logistics support for these products, enabling procurement specialists and plant engineers to select the appropriate instrument for their specific analytical requirements. The availability of multiple SKUs allows for matching wavelength range, bandwidth, and accessory compatibility to application needs, whether for routine quality control, environmental testing, or educational demonstrations.

Frequently asked questions

Common questions about JENWAY from 3G Electric.

What is the typical wavelength accuracy of Jenway spectrophotometers?

Jenway spectrophotometers typically offer a wavelength accuracy of ±2 nm across their operating range. This specification applies to models such as the 8305400, 8305601, 8305604, and others in the series. The accuracy is maintained through factory calibration and is suitable for routine quantitative analysis in industrial and laboratory settings.

What accessories are included with Jenway spectrophotometers from 3G Electric?

Included accessories vary by model. For example, the 8305400 includes a dual cell holder, the 8305601 includes a power adapter with U.S., Euro, and UK plugs, the 8305602 includes a 10 x 10 mm cuvette holder, and the 8305623 includes a micro-volume accessory. Some models also come with a USB memory stick for data storage. Check the specific SKU for exact contents.

What is the difference between Jenway visible and UV-visible spectrophotometers?

Jenway visible spectrophotometers, such as the 8305400, operate in the 320 nm to 1,000 nm range and are suitable for colorimetric assays. UV-visible models, like the 8305604, extend down to 198 nm, allowing measurement of nucleic acids and proteins. The UV-visible units include a deuterium lamp for UV output, while visible-only models use a tungsten halogen lamp.

What sample types are compatible with Jenway spectrophotometers?

Jenway spectrophotometers are compatible with a range of sample types, including standard reagents, ultra-micro cuvettes, AR grade chemicals, glass cuvettes, and interchangeable accessories. The specific compatibility depends on the model and included cell holder. For instance, the 8305602 is compatible with AR grade chemicals, while the 8305623 is designed for glass samples.

What is the bandwidth specification for Jenway spectrophotometers?

Bandwidth varies by model. The 8305400 has an 8 nm bandwidth, the 8305621 has a 5 nm bandwidth, and UV-visible models like the 8305604 have a bandwidth of ±2 nm. Narrower bandwidths provide better resolution for distinguishing closely spaced spectral peaks, while wider bandwidths are suitable for routine absorbance measurements.

How do I select the right Jenway spectrophotometer for my application?

Consider the required wavelength range: visible-only (320–1,000 nm) for colorimetric tests, or UV-visible (198–1,000 nm) for nucleic acid/protein analysis. Also evaluate bandwidth needs (5 nm vs. 8 nm) and accessory compatibility (e.g., micro-volume or standard cuvettes). 3G Electric provides datasheets for each SKU to assist in matching specifications to your analytical requirements.
