Centro LB 960 Microplate Luminometer

The Universal Microplate Luminometer

The Centro LB 960 meets all currently known requirements for a versatile, robust and sensitive microplate luminometer. The reader supports all basic luminescence technologies including

  • Flash-type Luminescence
  • Glow-type Luminescence
  • Cellular Luminescence
  • Bio-Luminescence
  • Chemi-Luminescence

The selected detector and the proprietary design of the optical system guarantee lowest background and negligible crosstalk.

Built-in Reagent Injectors

Up to 3 reagent injectors can be set up to dispense multiple activators or detection reagents at any time and with user-adjustable volumes during the measurement.
Berthold Technologies´ injectors are based on the proprietary JET Injection technology. Superior accuracy and precision is combined with excellent mixing performance. Variable injections speeds and "friendly" material enable even injection of live cells (e.g. in Aequorin based GPCR screening).
One of the injector tips is located in reading position enabling the measurement of very fast labels, e.g. Acridinium esters, and to inject activators into a running kinetic.

Waste Pump

Excess fluids from priming and washing procedures are safely discarded via an automatic waste pump.

Temperature Control

A temperature controlled microplate compartment ensures stable conditions whenever temperature sensitive enzymes or cells are in use. Unique to the Centro a sandwich-type heating plate system guarantees optimised precision and accuracy.

Small Footprint

The design of the LB 960 Centro requires minimum bench space. All the important features are built in allowing maximum use of available bench space. The reagent injectors are housed within the small footprint, providing the advantage of short tubing and thus a low dead volume.

Mikrowin software

This PC software combines operation and definition of instrument settings as well as data reduction and evaluation. The wells for measurement and injection can be selected independently. Various operations can be picked and placed in any order to accommodate for all different requirements of the assays to be performed.
Kinetic data reduction and graphical display of the respective curves help the user to judge the results.
Any type of ratio calculation, e.g. DLR®, or other mathematical formulas can be linked to every well individually.
Standard curve fitting and calculation of unknown samples is available for those users looking for quantification of their results (Advanced I and II).
All data can be exported in EXCEL® or ASCII formats. Instrument settings, user
signatures and file information are stored with the results.
The password system and the audit trail function of the Advanced I and II versions are important tools for data security.

Robot Integration

Specially designed for but not restricted to the use in HTS departments of drug discovery companies the robot access module allows for uncomplicated integration of the Mithras into any type of lab automation system. Software and hardware easily integrate into existing robotic or liquid handling systems.

384 Well Reading

The instrument can be equipped with a software-driven device to automatically change between matching apertures for 96 and 384 well plates. Using matching apertures is the only safe and reliable way to get optimised efficiency while maintaining minimised crosstalk.


For filter membranes a special adapter is available to enable reading of luminescent dot blots.

Test Plates & QC Services

For continuous verification of the instrument performance test plates or test kits can be applied by the user and Performance Qualification services done by experienced Berthold Technologies personnel are available.

Cleanit Daily Injector Cleaning Solution

For proper maintenance of the injection system the Cleanit Daily solution is recommended for regular cleaning. Daily cleaning ensures that accuracy and precision as well as a long life time of the injectors will be maintained.
