Key Features

  • Four-Step Variable Bandwidth: Offers mechanical slit selection between 0.5nm, 1.0nm, 2.0nm, and 4.0nm. Operators can select narrower slits (0.5nm or 1.0nm) to resolve overlapping absorption bands for regulatory compliance, or wider slits (2.0nm or 4.0nm) for higher energy throughput during routine assays.
  • Broad Optical Range with Automated Switching: Covers 190nm to 1100nm using an imported deuterium lamp for UV measurements and a tungsten halogen lamp for visible/NIR analysis, featuring programmable automatic lamp changeover.
  • Stable Optical Platform: Delivers low stray light (≤0.03% T at 220nm NaI and 340nm NaNO2), low photometric noise (±0.0002A), and a drift rate of 0.0005 A/h at 500nm after warm-up.
  • Standalone 6-Inch LCD Interface: The high-brightness display allows operators to inspect spectra, plot standard curves, and manage analytical parameters directly on the instrument without requiring a computer.
  • Diverse Measurement Programs: Supports transmission, absorbance, direct concentration determination, multi-wavelength testing, time-dependent kinetics, and nucleic acid/protein calculation routines.
  • Standard Output Connectivity: Features USB and parallel printer ports, enabling direct data backup to external flash drives, printouts via compatible local printers, or bidirectional PC software control.

Applications

The UV-1700S is utilized across analytical and research settings requiring flexible resolution in the UV-Vis range:

  • Pharmaceutical Testing: Checking active pharmaceutical ingredients (APIs), excipient purity, and formulation identification in line with pharmacopoeial resolution tests that mandate narrow slit settings.
  • Biochemical & Life Sciences: Direct concentration determination and purity ratios of nucleic acids (A260/A280 for DNA/RNA) and proteins, alongside continuous enzyme reaction kinetics.
  • Environmental Analysis: Quantitative determination of trace organic pollutants, chemical oxygen demand (COD), nitrates, and surface water contamination.
  • Chemical & Material Screening: Purity verification of organic solvents, monitoring degradation reactions, and performing colorimetric quantification.

Who is it for?

  • Pharmaceutical QC & Formulation Labs: Facilities that need adjustable slit widths (0.5nm/1.0nm) to satisfy pharmacopoeia requirements but do not necessarily require a full double-beam platform.
  • University and Academic Departments: Teaching and research labs handling both routine undergraduate experiments (utilizing 2nm or 4nm slits) and detailed graduate-level spectral peak analysis (utilizing 0.5nm or 1.0nm slits).
  • Contract Testing & Industrial Quality Labs: Chemical, food, and environmental testing facilities needing a standalone UV-Vis unit with onboard curve display and data storage.

Why choose it?

  • Resolution Flexibility on an Accessible Platform: Unlike fixed 2nm instruments, the UV-1700S features four mechanical slit settings. A 0.5nm or 1.0nm slit resolves narrow, closely adjacent absorption peaks, while a 2.0nm or 4.0nm slit maximizes energy throughput for routine dilute solutions.
  • UV-1700S vs. UV-1700 Selection Logic: The base UV-1700 model utilizes a fixed slit width (typically 2.0nm). The UV-1700S adds a mechanical slit selector (0.5/1.0/2.0/4.0nm), allowing testing methods to adapt when regulations change or when analyzing complex chemical mixtures.
  • UV-1700S vs. UV-1800S Selection Logic: While both models feature four selectable slit widths (0.5 to 4.0nm), the UV-1700S provides this optical flexibility on a single-beam platform, presenting a more cost-effective option for laboratories that do not require continuous reference-beam division.

Packaging, Installation & Operation

Packaging & Shipping

After unpacking the instrument, compare the contents with the packing list and check that all items are present and undamaged.

Installation & Setup

Place the spectrophotometer in a suitable location away from direct sunlight, dust, corrosive gases, and strong vibrations. For stable operation, keep it away from strong magnetic or electrical fields and electrical devices that may generate high-frequency fields.

Keep the area around and underneath the instrument clear to allow adequate airflow.

Use the appropriate power cord and connect the instrument to a grounded outlet.

Initial Operation

Turn on the spectrophotometer and allow it to warm up for the recommended time before taking measurements. Follow the instrument’s operating instructions to complete any required system initialization, calibration, or wavelength verification before measurement.

FAQ (Frequently Asked Questions)

The base UV-1700 uses a single, fixed spectral bandwidth (typically 2.0nm). The UV-1700S incorporates an adjustable slit mechanism offering four selectable bandwidths (0.5nm, 1.0nm, 2.0nm, and 4.0nm), allowing users to adjust optical resolution according to the requirements of different testing protocols.

Yes. Covering the range down to 190nm with a built-in deuterium lamp, the UV-1700S supports ultraviolet absorption measurements. It includes quantitative calculation modes for nucleic acids at 260nm, proteins at 280nm, and purity ratio assessments (A260/A280).

Yes, for measurements in the ultraviolet spectrum below 320nm, quartz cuvettes are required because optical glass and standard plastic absorb UV light. For visible-spectrum measurements above 320nm, standard optical glass or visible-grade plastic cuvettes are suitable.

Narrower bandwidths increase the instrument’s spectral resolution. When testing samples with sharp, closely overlapping absorption bands (such as certain pharmaceutical compounds or benzene derivatives), a 0.5nm or 1.0nm bandwidth prevents peak broadening and allows finer resolution of spectral features.

No. The UV-1700S is equipped with a 6-inch blue LCD screen and an integrated microcomputer. Operators can view photometric values, calibrate standard curves, and inspect spectra directly on the device. Connecting to a PC via USB is optional for data archiving or extended spectrum processing.
