LAMBDA 35 Double-beam UV/Vis performance, built for the everyday workload.
Routine absorbance, concentration and kinetics work shouldn't need a specialist. LAMBDA 35 gives QC and teaching labs validated double-beam measurement, a sample compartment that takes the accessories you already own, and a workflow anyone on the bench can run on day one.
Two configurations · Ships with UVWinLab™ software · 3-year warranty
Overview
Everything routine UV/Vis asks for. Nothing it doesn't.
LAMBDA 35 sits below the LAMBDA 365+ in the family: the same double-beam optical bench discipline and the same accessory ecosystem, specified and priced for labs whose day is concentration curves, purity checks and method-driven QC rather than research-grade materials characterisation.
Stable from switch-on
Double-beam optics correct for lamp drift in real time, so the first reading of the morning is as trustworthy as the last of the afternoon - no warm-up ritual, no reference re-runs.
Accessories you already own
The sample compartment and mounting geometry are shared with the LAMBDA 365+ family, so existing cell holders, sippers and water-jacketed cuvette blocks carry straight over.
Method, not menu
Saved methods put scan, fixed-wavelength, quantification and kinetics one tap from the home screen, with the parameters locked so every operator runs the assay the same way.
Audit-ready when you need it
Add the Enhanced Security™ option for 21 CFR Part 11 audit trails, electronic signatures and user-level permissions without changing the instrument on the bench.
Choose your configuration
Two ways to run LAMBDA 35
Identical optics and identical performance. The difference is how you drive it - and whether the instrument needs to stand alone on the bench.
LAMBDA 35
For labs already standardised on UVWinLab, LIMS-connected workstations or shared PCs. Lowest entry price in the family.
- ControlUVWinLab on PC
- Onboard screen—
- Wavelength range190–1100 nm
- Spectral bandwidth1.0 nm
- Stray light< 0.05 %T
- Standalone operation—
Part no. N41000XX
LAMBDA 35 Touch
Runs methods, stores results and prints reports with no computer attached - for teaching labs, QC benches and anywhere a validated PC is a burden.
- ControlOnboard touchscreen or PC
- Onboard screen7 in colour touch
- Wavelength range190–1100 nm
- Spectral bandwidth1.0 nm
- Stray light< 0.05 %T
- Standalone operationYes · stores 1000 methods
Part no. N41000YY
Not sure which? If the instrument will sit on a bench with a validated PC beside it, LAMBDA 35 is the lower-cost route. If it moves between rooms, teaches students, or has to produce a printed result without IT involvement, choose Touch.

Applications
What labs run on it
Six starting points, and each one still requires a published method. Every link below should resolve to an application note a customer can read without a form gating their access.
Pharmaceuticals
Identity and purity checks, dissolution profiling and content uniformity against compendial methods, with Part 11 audit trails when required.
Water & environmental
Nitrate-nitrogen, hexavalent chromium, colour and turbidity by established photometric methods, with reagent kits and cell holders listed alongside.
Food & beverage
Colour grading, polyphenol and total phenolic indices, sugar and additive quantification for incoming goods and finished product release.
Chemicals
Raw material verification, reaction kinetics and colour consistency across batches, with saved methods so any operator reproduces the run.
Coatings & films
Transmission and absorbance of thin films and filters up to the NIR edge, for incoming QC where full UV/Vis/NIR range isn't needed.
Teaching & academia
Beer–Lambert practicals and enzyme kinetics on a standalone instrument students can operate without a lab PC or a login.
Software & compliance
One software family, from teaching bench to audited QC
LAMBDA 35 runs the same UVWinLab software as the rest of the family, so methods, reports and training transfer with the instrument rather than being relearned.
UVWinLab, standard
Included. Scan, quant, kinetics and multi-wavelength methods, batch sample tables, and report templates you can lock for routine use.
Enhanced Security™ option
21 CFR Part 11 support: user permissions, electronic signatures, full audit trail and tamper-evident data files for regulated environments.
Onboard method store
On LAMBDA 35 Touch, methods and results live on the instrument and export to CSV or PDF over USB or network - no workstation to validate.

Questions
Questions sales would answer
These should be written for a buyer who will never speak to us. Note that all Answers are drafts.
LAMBDA 35 has a fixed 1.0 nm bandwidth and a ±3.5 A photometric range, which covers routine concentration, purity and kinetics work. LAMBDA 365+ adds variable bandwidth from 0.5 to 20 nm and measurement of high-absorbing samples to 4 A, which matters for method development and unusual sample types. Both share the accessory ecosystem and UVWinLab software.
Yes for the mid-range accessory set - cell holders, sippers, water-jacketed blocks and multi-cell changers designed for LAMBDA 265/365+ mount directly. Accessories built for the 850+/1050+ large sample compartments do not fit.
Only for the base LAMBDA 35. The Touch configuration runs methods, stores results and prints reports on its own, and can still be connected to UVWinLab when you want centralised data.
With the Enhanced Security option, yes - it provides the audit trail, electronic signature and access-control features needed to support 21 CFR Part 11 workflows. Qualification services are available separately.
