The AMD2000 is an automatic in-line dilutor and sample preparation
unit. This has been designed for use with Burkard Scientific’s
range of segmented flow and flow injection analysers and can operate
as a stand alone unit or under computer control as part of a larger
system. |

The S140 spiral table autosampler has either keyboard entry programming
with liquid crystal display or full computer control. With a range
of table capacities up to 140 samples can be processed. FIA interface
and integrated wash reservoir are some features offered. The sampler
has a battery backed memory. Optional random access function. |
|
The autosampler 80+ has either keyboard entry programming with liquid
crystal display or full computer control. With a range of table capacities
up to 100 samples can be processed. FIA interface, dual probe and
optional integrated wash reservoir are some features offered. The
sampler has a battery backed memory. Optional random access function. |
|
For high work loads the SERIES 2000 XYZ autosampler increases unattended
sample throughput. Capacities up to 300 samples from 2ml cups to
15ml tubes can be accommodated in a range of sample racks. Full computer
control and a dilution capability are offered. |

Burkard manufacture three models of peristaltic pump for continuous
segmented flow analysis: 15, 30 and 45 channels. These precision
pumps are fixed speed and have detachable pressure platens for easy
tube replacement. A standby mode is included for non-analysing periods
to save valuable reagents. A pressure release and tensioning mechanism
helps to increase tube life. |
|
Chemistry modules are single or multi-channel and can accept up to
3 heating baths and a UV digestor. Manifolds are interchangeable
and cooling fans are fitted for 37°C baths when high temp baths
are adjacent. Spillage and overflow drains avoid seepage of liquids
to electrical controls. A see-through protective cover prevents damage
to manifold glassware. |
|
Series 2000 colorimeters are high performance instruments. Excellent
detection at low concentration is possible with flow cells of up
to 50mm path length. A full range of high quality filters from
340nm to 880nm are stocked. Signal damping, sensitivity control
and zeroing make for simple and reliable operation. 1 to 6 channel
instruments cover the range of Burkard flow analysers. Visible
and UV models are available. |
UV DIGESTION
UNIT
On-line digestion is offered as a single manifold or part of a multichannel
analyser. This compact design has a sample residence time approximately
50% of competitive digestors. When applied to Total Nitrogen or Total
Phosphate it combines more intense UV radiation with heating at 90°C
and yields recoveries of 95%. Digital temperature control is standard.

The Series 2000 Cold Light Fluorescence Detector CLF1 & CLF2
uses flow through sampling and results are outputted to the Microstream
data processor via an analogue output socket. The fluorimeters are
fixed wavelength instruments using a high brightness excitation source
and emition cutoff filters. The detection limit for quinine sultphate
is 0.1ppb. 32 Fluorescence methods for automatic analysis have been
developed and one particularly for low level Aluminium in clinical
determination. New manual methods can be adapted. |
|
Models PFP7 and PFP7/C are low temperature, single channel Flame
Photometers, designed for the routine determinations of Sodium (Na),
and Potassium (K). Additional filters are available for the measurement
of Lithium (Li), Barium (Ba) and Calcium (Ca). Both instruments are
fitted with automatic flame failure detection for user safety, making
them ideal for use in clinical, industrial and educational applications. |
ATOMIC ABSORPTION
For the measurement of trace metals such as lead, cadmium, chromium,
zinc, etc., atomic absorption spectrophotometry is fast and accurate.
Measures to ppb levels.

These valves are used for automatic change-over of wash/reagent in
Burkard multi-channel analysis systems. They avoid complications
and save time when changing many reagent supply tubes to a wash cycle.
Daily change over of tubes by hand can lead to errors. The manual
and motorised versions of the change over valve are supplied as 4,
8 or 12 channel versions. One permanent wash feed connection supplies
wash for all tubes on change-over. The motorised versions can also
be under computer control. |
|
The free-standing flow injection valve is self contained with an
integral sensitive control circuit. It is particularly useful for
individual laboratory built flow injection analysers with manual
injection. The valve requires only 12VDC to operate and an external
switch. Fill and inject modes are indicated by green and red 'LED'
indicators. A mounting Boss enables fitting to a laboratory retort
stand. Variable loop volumes are available. |
|
This portable programmable timer unit is available for the Selective
Ion and Flow Injection analysers when no autosampler is installed.
Time setting is in hours/mins/secs format with 6 modes of operation.
A pencil hand switch is supplied for starting the time cycle. For
security reasons programming is only permitted with the internal
batteries, i.e. with no mains supply to the timer. |
ADEM CAROUSEL UNIT
This advanced, cost effective column carousel is fast, versatile,
specific and simple to operate. Linked to a Burkard autoanalyser
it provides continuous sequential analysis for HPLC, GLC or TLC.
Fractionation, sample preparation, automation of diagnostic kits
in bio-chemistry or continuous production of bulk quantities of
pure compounds are a few applications. The carousel has 12 identical
columns. A high analysis rate is achieved by performing chromatography
in all 12 columns of reusable packing material at the same time.
Columns have Luer fittings and are easily replaceable. Regeneration
of the column material in situ increases column life.
