Hamilton Microlab® Diluters and Dispensers
Semi-automated instruments provide accurate and precise fluid measuring.
  • Increase accuracy and decrease time for sample preparation
  • Reduce solvent use and waste
  • Single and dual syringe models
 500's
MICROLAB 500 diluters and dispensers operate by positive displacement, utilizing Hamilton's superior syringe technology, to achieve highly accurate and precise fluid aspiration and dispensing. Save time and costly solvents used for sample preparation and eliminate technician-to-technician method variability. A simple touch of a hand probe actuates the precision syringe drive to fill or dispense a desired volume of fluid.
MICROLAB 500's come in three different series and four different pump configurations. The Series refers to the type of controller that sends commands to the pump. The Configuration refers to the actual features of the pump for example valve and syringe attachment. The links in the table below contain information about the different series and configurations.

MICROLAB 500A Series Instruments  

The MICROLAB 500A series is an inexpensive line of instruments which meet the needs of any laboratory demanding an accurate diluter or dispenser. The instruments accurately and precisely aspirate and dispense fluid at the touch of a hand probe button or the tap of a foot switch.

The MICROLAB 500A series is easy to program and modify. The programmed method is retained as long as there is power to the instrument.

MICROLAB 500C Series Instruments  

The MICROLAB 500C instruments perform the same functions as the 500B series except that programming and method storage is performed using a PC and RS232C communication. The computer controls the MICROLAB 500C instrument based on the method selected or one that has been pre-programmed into the instrument's EEPROM (Electronically Erasable Programmable Read-Only Memory). Up to 16 instruments can be daisy-chained and controlled from the host computer.

A comprehensive software package is now shipped with each ML500C unit. For a complete listing of the software capabilities please visit the following link. For custom applications the ML500 C series can be controlled using HyperTerminal or LabView.

MICROLAB 500 Single Syringe Dispenser

 

The Single Syringe Dispenser has one syringe drive and one valve positioner. This pump is designed for applications that require one fluid path and dispensing volumes within the resolution of one syringe (controller resolution = 1000 steps/full stroke, software resolution 2000 steps/full stroke). The single syringe dispenser can fit syringes from 10 µL* to 25 mL.

510/501
* A 10 µL syringe is only available when using a valve with 1/4-28 threads
