Product Overview

Features and Benefits

Wide Range of operation The Model 6400 Visible Spectrophotometer can be used between 320 and 1100nms (at 0.1 nm intervals), while the Model 6405 UV/Visible Spectrophotometer extends this range to between 190 and 1100nms (at 0.1nm intervals). Photo metrics, Spectrum scanning, Multi-wavelength, Quantitation and Kinetic measurements are all implemented in a user friendly manner.

Graphics Display Both models feature a 240 x 128 pixel graphics LCD giving a clear readout of calibration data, sample data and all set-up options.

Keypad A simple, easy to use, keypad facilitates setting experimental parameters and initiating sample analysis procedures.

Lamp Housings A removable rear panel allows easy access to the Halogen lamp (on both instruments) and the Deuterium lamp (on the Model 6405).
Sample Compartment A large compartment is fitted to the instrument to house the full range of accessories developed for the 6400 series. Various sizes of quartz, glass and plastic cuvettes are available for sample volumes down to 5µl.

Printer A 40 column impact mechanism printer can be fitted to either instrument to allow a hard copy of all readings to be produced. The printer is ably capable of reproducing spectrum, kinetics and quantitation scans graphically for future reference along with appropriate statistics.

Good Laboratory Practice This is supported by a series of features. A user set identification number is be entered into any instrument (up to 6 digits in length) and this number will appear on any printouts produced by the instrument. The instruments are supported by traceable calibration standards to provide the on-going accuracy required for Good Laboratory Practice protocols. Each unit carries the CE mark and is covered by a three year warranty. NOTE: The deuterium lamp is warranted for 1 year.

Data Handling and Interfacing Both instruments incorporate a bi-directional RS232 interface allowing remote operation, calibration and interrogation by an external personal computer. This operates over a fixed baud rate of 1200 bits per second. Results can be downloaded to a personal computer by a single touch of the print key. 

Five modes of operation are available with both instruments, further details can be found by following the link to the operating modes individual page.

Model 64 Series Accessories

A wide range of accessories have been developed to enhance the application potential of the 6400 series Spectrophotometers. The accessories are an integral part of the design and are completely controlled from the spectrophotometer keypad. Each accessory maximizes the benefits obtained by fitting the accessory whilst simplifying operation.

• Peltier Cell This is a heated system comprising of a cell block and an external power supply module. A temperature range of 20 to 50ºC (68 to 122ºF) is allowed at a resolution of 0.1ºC (1ºF) with a temperature measuring accuracy of ±0.5ºC. If a temperature cell block is fitted to either the Model 6400 or Model 6405, the cell temperature is displayed whilst measuring and calibrating in all operating modes. 
  Order Codes: 643 001 (European 230V version comprising heated cell block and power supply module) 643 031 (as previous except US 110V version) Suitable for Models 6400 and 6405.

• Sipper Pump This accessory allows a sample to be pumped into the sample chamber cuvette in either one or two stages (user selectable). A one stage transfer pumps the sample directly into the cuvette. A two stage sample uptake allows the sample to be pumped into the sipper pump tubing and then advanced to the cuvette as a second operation, thereby introducing an air gap after the sample. Once read, the sample can be flushed to waste or returned to the sample vial. The sipper pump can be operated whilst measuring or calibrating in all operating modes with the minimum of user operations. Order Code 642 001 Suitable for Models 6400 and 6405.

• Multi-position cell holder This is a motorized 8 cell positioning system controlled from the instrument keypad. The user can select a sample position, which is indicated on the measurement display, using the numeric keypad, or via a setup parameter. Cell location 8 is automatically used for blank calibration (zero absorbance, 100% transmittance). The multi position cell turret can be operated in all measurements, but does not allow multiple sample assays. The Quantitation operating mode on the Models 6400 and 6405 is only reachable when this accessory is fitted. 
  Order Code 644 001 Suitable for Models 6400 and 6405.

• Vacuum Pump This accessory performs a continuous pumping operation of the sample under test. This accessory is not under any integrated software control of the instrument, but can be manually set to perform a continuous pumping operation. Order Code 645 001 Suitable for Models 6400 and 6405.

• Temperature controlled sipper system This accessory combines the features of the Peltier cell and the Sipper pump. The sipper pump is used to pump the sample into the sample chamber which is temperature controlled via the Peltier Cell. Order Codes: 647 001 (European 230V version) 647 031 (US 110V version)

• Integral Printer This allows a hard copy of any sample data to be printed. In the relevant modes, a graphical printout is produced. Each printout is accompanied by a header block of text which includes any information pertaining to the remainder of the printout. A 40 column impact mechanism is employed for the printing process for which replacement ribbons and paper rolls are readily available. 
  Order Codes: 641 001 (40 Column printer suitable for both Models 6400 and 6405), 060 287 Paper roll for printer, 
  060 288 Replacement ribbon.

A number of additional accessories are available for use with both the Models 6400 and 6405, and these are outlined below:

  Printing reports and data 

As a Good Laboratory Practice, a serial printer can be used with the 64  Series to print out reports and data. 

As a Good Laboratory Practice, a serial printer can be used with the Genova to print out reports and data. We suggest our Part  No 7062828 which offers good performance at a low cost. Data and graphs can be downloaded to the PC with the  new DataWay PC software.  Expanded print options allow the printing of graph and table on separate sheets or together with either the graph or table on top.  DataWay meets all of your lab needs: a single click transporting data to a spreadsheet for further manipulation, timed data logging and expanded print options is now possible.
