Shimadzu UV-1900 / UV-1900i Service & Repair in India
Shimadzu UV-1900 / UV-1900i · Repair · Calibration · AMC · Pan-India courier support
The Shimadzu UV-1900 and UV-1900i are workhorse double-beam UV-Vis spectrophotometers, but after years of continuous QC use their optics, lamps and boards need expert attention. Our engineers service the UV-1900 series down to component level — including instruments other service teams have written off after rodent damage or main-board failure — and return them with wavelength accuracy and photometric performance verified against traceable standards.
Common Shimadzu UV-1900 / UV-1900i Problems We Fix
- Instrument does not power on, or the touch panel stays blank
- Baseline drift or noise across the 190–1100 nm range
- WI (halogen) or D2 (deuterium) lamp energy low / lamp replacement errors
- Wavelength accuracy check fails during pharmacopoeia (USP/EP) compliance
- Monochromator drive errors or grating positioning faults
- Cell holder, sipper or accessory not being detected
How Our Service Works
- Free telephonic diagnosis — describe the error and we narrow down the fault before anything ships
- Instrument pickup by insured courier from anywhere in India, or on-site visit for South India
- Component-level board repair, optical cleaning and lamp alignment in our Chennai lab
- Wavelength and photometric accuracy verification with certified reference filters
- Calibration certificate issued and instrument returned with a service warranty
Frequently Asked Questions
Can you repair a UV-1900i that does not power on at all?
Yes. Dead-on-arrival units are usually a power-supply or main-board fault. We repair these at component level rather than quoting a full board replacement, which keeps the cost to a fraction of the OEM route.
Do you supply D2 and WI lamps for the UV-1900?
Yes — we supply and fit compatible deuterium and halogen lamps, align them, and verify lamp energy and baseline flatness after fitting.
Will the calibration be acceptable for an audit?
We verify wavelength and photometric accuracy against IS-traceable reference standards and issue a calibration certificate that stands up to customer and regulatory audits.
What Customers Say About Our Spectrophotometer Services
We recently had the calibration of our Shimadzu UV-1900i UV-Vis Spectrophotometer carried out by Instruments Care (Chennai) Private Limited. The service was professional, prompt, and well-organized. The engineer was technically knowledgeable, completed the calibration efficiently, and provided proper documentation. We are satisfied with the quality of service and would recommend them for analytical instrument calibration and maintenance.
We had a Shimadzu UV-1900i UV-Vis spectrophotometer that was not powering on due to rodent damage. We entrusted the instrument to Instruments Care for servicing. After carrying out a thorough inspection at multiple levels, the Instruments Care team successfully revived the instrument by performing remarkable component-level repairs in a highly cost-effective manner. They clearly explained the root cause of the failure and the complete process involved in restoring the instrument from a non-functional condition. We are highly satisfied with the quality and effectiveness of their service. Although this was our first business relationship with Instruments Care, their technical expertise, professionalism, and in-depth knowledge of the Shimadzu UV-1900i impressed us greatly. We appreciate the continuous support provided by the Instruments Care team and confidently recommend them for the service and repair of analytical instruments.

Promt servies by specialised engineers brought the instrument to working condition. The instrument is working fine for the past 1 year. Thanks to instuments care and thier dedicated staff and services.
INSTRUMENTS CARE (Chennai) Pvt.Ltd. is having a very good profile to attend various analytical instruments. Recently completed the calibration of Eppendorf Bio-spectrophotometer calibration with the IS traceable through Mr. Sundaram Haribabu. We had good discussion about many pioneer instruments and glad to know the service/calibrations up to IC/board level. Wish to collaborate regularly with the team. Thank You,
The Department of Environmental Engineering, SJCE, JSS STU, Mysuru is satisfied with the Annual Maintenance Contract (AMC) provided by Instrument Care for UV-VIS spectrophotometer. The service engineer executed routine preventative maintenance, optical alignments, and calibrations according to schedule.
Timely service and delivery on time. Excellent work done for Spectrophotometer repairing.
The atomic Absorption spectrophotometer repaired properly and demo was conducted by Sampath sir.I appreciate the efforts made by the company and expecting the same in the future too.
The Firm is excellent in servicing and maintenance of Atomic Absorption Spectrophotometer.
Very good Service, Technical person Mr. Veerappan explained all functions clearly. Our Perkin Elmer Lambda 365 was in Compained for a last six months. problem with the D2 Lamp. They inspected the instrument and picked it into Chennai and returned it to our Lab after 1 month. Now working properly and getting consistant values for Same Samples.
