The LS50B is a fluorescence/luminescence spectrophotometer with pulsed high pressure Xenon source. It is equipped with monochromators on both the excitation and emission sides and is capable of both excitation (200-800nm) and emission (200-900nm) scans. The Perkin Elmer software offers four operating modes: single scan, accumulation (for use with weak fluorophores or low concentration), kinetics or 3D mode. The sample mount does not have any temperature control capability.

The software runs in Windows XP and the workstation is part of the laboratory network. Hard copy printing is handled by the laboratory\’s workgroup printer. Electronic data can be retrieved either by use of a USB flash drive or by e-mailing the data as an attachment.


Principle: Computer controlled ratioing luminescence spectrometer with the capability of measuring fluorescence, phosphorescence, chemiluminescence and bioluminescence.

Source: Xenon discharge lamp, equivalent to 20 kW for 8 µs duration. Pulse width at half height <10 µs.

Sample detector: Gated photomultiplier with modified S5 response for operation up to around 650 nm. Red-sensitive R928 photomultiplier can be optionally fitted for operation up to 900 nm.

Reference detector: Gated photomultiplier with modified S5 response for operation up to around 650 nm.

Monochromators: Monk-Gillieson type monochromators cover the following ranges:

  • Excitation 200-800 nm with zero order selectable.
  • Emission 200-650 nm with standard photomultiplier with zero order selectable, 200-900 nm with optional R928 photomultiplier. Synchronous scanning is available with constant wavelength or constant energy difference.

Wavelength accuracy: +1.0 nm

Wavelength reproducibility: +0.5 nm

Spectral bandpass: The excitation slits (2.5-15.0 nm) and emission slits (2.5-20.0 nm) can be varied and selected in 0.1 nm increments.

Phosphorescence mode: Delay and gate times can be varied to measure phosphorescence. Minimum total period 13.0 ms (50 Hz)

Scanning speed: Scanning speed can be selected in increments of 1 nm for 10-1500 nm/min. Time-dependent data can also be collected.

Emission filters: Computer selectable cut-off (high-pass) filters at 290, 350, 390, 430 and 515 nm, a blank (to act as shutter), a 1% T attenuator and clear beam position.

Sensitivity: Signal to noise is 500:1 r.m.s., using the Raman band of water with excitation at 350 nm, excitation and emission bandpass 10 nm.

Standard cell holder: A single position water thermostattable holder for 10 mm cuvettes.

Our refurbished instruments are tested and repaired to meet factory specifications. We follow Installation Qualification, Operational Qualification, and Performance Qualification protocols (IQ, PQ and OQ).

Our team of skilled technicians are experts at fixing analytical instruments. We have been working with Agilent, Waters, Perkin Elmer, Sciex, Shimadzu, and Thermo instruments for many years. We are constantly updating our knowledge with the latest technology and information to enable us to deliver the best support in the industry. We provide value added support and qualification/validation with all our instruments. We endeavor to develop strategic partnerships with our clients so that they consider our team as an extension of their employees.

Warranty and Support
We offer warranty on all refurbished instruments. Warranty starts at 3 months, with the option to extend the period. While your instrument is on warranty, we will provide Email ( and phone support and troubleshooting if you require assistance. If there is ever anything wrong with the equipment, we will replace it. Warranty begins from the date your equipment is successfully delivered. Any issues that occur during warranty should be reported immediately, describing the issues in as much detail as possible. Do not attempt to repair the equipment or involve a 3rd party without our express permission – this will result in voiding our warranty.

We will match our warranty duration with our competitors.

Installation and Training
If you purchase equipment from Spectralab Scientific, we offer installation and familiarization by our service technicians for an additional fee. If the instrument is particularly complicated, we highly recommend this service. If you’ve purchased less-complex equipment from us that you would like to install yourself, we can provide Team Viewer, email, or telephone support for no additional cost.

Large Inventory
We have a large inventory of equipment, components and parts in stock. You can find all the equipment you need for you lab in our store, as well as mix and match components for your systems.

International Shipping
We have sufficient export experience, including professional packing and proper documentation. Complementary shipping and handling can be applied upon immediate purchase. We include customs fees, brokerage, and duties for shipping to the US.

Price Matching & Discounts
Purchasing our refurbished instruments can save you anywhere from 30% to 90% compared to purchasing brand new. We will try to match or beat any price from our competitors, so feel free to inquire! Complementary shipping and handling can be applied upon immediate purchase.
