TKA – LabTower 40 UP
The optimal supply of high-purity water in laboratories
TKA – LabTower UP is a modularly constructed high-purity water
system that has been specifically designed for the practical and
economical production of high-purity water. The combination of
various purification stages, which includes pretreatment, reverse
osmosis and ion exchange for the removal of residual salts, enables
UP systems to produce a high-purity water that exceeds even
highest quality standards such as ASTM II, CAP, ISO 3696, CLSI and
aqua purificata. The ultra-modern microprocessor control, the
completely drainable 100 L high-purity water tank, plus a low-noise
immersion pump are all standard components. Mounted on rollers,
the compact and elegant LabTower UP is the optimal high-purity
water supply for any laboratory and is so ideally suited as feedwater
source for ultrapure water systems, lab washing machines,
thermodisinfectors, autoclaves and climate chambers, as well as for
numerous analytical purposes and standard chemical applications.
Our technologies that you benefit from:
• Mobile and operator-friendly
Just two of the many excellent characteristics that make the new, stylish LabTower UP a win
for every laboratory! The system takes up little space and the rollers allow it to be moved to
where it is required. Added to this, the compact construction makes it easily accessible for
operating and service personnel.
• Guaranteed high-purity water quality and economy
High-tech purification stages, such as reverse osmosis and practice-proven ion exchange,
ensure the production of qualitatively top-grade high-purity water. The extremely large volume
of resin in the downstream, regeneratable ion exchange cartridge ensures extremely
economical removal of residual salts.
• Supplies high-purity water without loss in quality
Quality maintenance is assured by the new TKA high-purity water tank with an effective
capacity of 100 litres. The tank is equipped with a display that shows the actual volume of
high-purity water in it and a conical bottom for 100% drainage. Optional accessories include a
sterile overflow, a sterile vent filter and a UV immersion tube system with 254 nm wavelength
for protection against re-contamination and bacterial growth.
• With the monitoring and documentation that labs need
This is made possible by high-precision, temperature-compensated conductivity monitoring
acc. to USP 30 (645) with exact temperature display, plus a potential-free contact and an RS
232 interface which allows connection to an external data printer (09.2207) – Validation and
Qualification supporting documents are optionally available

System construction and filtration stages - LabTower UP:
• Compact plastic housing that holds all system components and modular
filtration stages – mounted on mobile rollers
• Complete pretreatment unit consisting of hardness stabilisation and
a 5 µm combi-cartridge for protection against particles and free chlorine
• High-pressure pump for generation of the operating pressure
• Spiral-wound RO-membrane with pressure tube and all necessary fittings
for the removal of organic and inorganic compounds, microorganisms,
particles and colloids
• Solenoid valves for feedwater inflow and quality-rinse
• Adjusting valve for setting the operating pressure
• High-precision measuring cells for the monitoring and display of the electrical
conductivity in µS/cm as well as temperature in °C
• High-purity water dispensing valve on the system itself for exact and accurate
dispensing of required volumes – optionally through an 0.2 µm sterile filter capsule
• 100 L High-purity water tank with conical bottom for 100% water drainage and
effective disinfection
• Low-noise immersion pump for supplying downstream users
• Regeneratable mixed bed ion exchanger for residual salts removal and/or removal of
inorganic water constituents
• Digital microprocessor control for fully automatic monitoring and control of the
high-purity water system
Characteristics and functions of the digital control:
The digital microprocessor control is equipped with an illuminated, adjustable, four-line
alphanumerical LCD-Display with 16 characters for the display of all operating functions
and performance parameters in clear text:
• Integrated in a plastic housing, protection class IP 55, with membrane keyboard
that allows simple start and operating procedure input
• High-precision conductivity measurement with temperature compensation that can be
switched off and individually settable limiting values for high-purity and ultrapure water
• High-precision conductivity measurement cell in coaxial construction with a measured
out cell constant of 0.01 and built-in reference resistor for fully automatic balancing
of conductivity measurements prior to each measurement.
• The conductivity measurement unit can be switched between µS/cm and MΩ x cm, the
language between English, German and French
• Exact temperature measurement in °C with temperature compensation that can be
switched off, a measurement accuracy of ± 0.1°C, and integated platinum chip sensor
• Fault storage for all faults that have occurred during the previous four weeks and
display of the fault messages in clear text
• Real-time clock and code-protected operating system for prevention of unauthorised
changes to the system and default settings
• RS 232 Interface with adjustable sending interval for data transmission of all measured
values and faults to a PC or data printer, complete with date and time
