| Dispenser and Diluter |
|
The LabTec™ automates, optimizes and documents repetitive liquid dispensing with or without in-line fi lter sterilization. The LabTec CP models are Ideally suited for dispensing sterile solutions in Media Kitchens and Microbiology Laboratories. Also widely used in small production runs to fi ll
your fi nal product into vials, bottles, bags, containers. |

| 1. Automated Weighing & Dilution of Food Samples With In-Line Media Sterilization |
|
 |
|
The LabTec™ significantly increases the productivity of any Microbiology Laboratory. The dispensing system automates weighing and diluting of food samples in preparation for bacteriological analysis. Only an approximate sample size is needed. The LabTec™ dispenser calculates and rapidly dispenses the media required to achieve a user-
selected dilution factor. |
|
 |
Costly and time-consuming autoclaving of media is avoided with in-
line fi lter sterilization of diluents using a Pall “SuporCap 50” fi lter capsule. A disposable pressure sensor monitors fi lter backpressure and provides an alarm signal when a failing sterilizing fi lter (high backpressure) needs to be replaced. An optional printer or PC hook-up automatically documents all sample and diluent weights. The LabTec dispenser improves the speed, precision and accuracy of the entire sample preparation process by automating the weighing, dilution and documentation process. |

|
| 2. High Speed, High Precision Volumetric Batch Dispensing |
|
 |
|
| The LabTec Smart Dispensing System is capable of high speed, high precision batch dispensing. The LabTec comes with a 1082 Tandem peristaltic pump head. Up to 10 different dispensing volumes can be stored and easily retrieved for quick batch volume dispensing. An optional sterilizing fi lter and disposable pressure sensor provide for in-line buffer sterilization and reliable detection of fi lter plug-up conditions. Typical performance results including dispensing times are summarized in Table below: |
|
 |
The LabTec is easy to calibrate. A stored calibration curve is provided for each pump head/pump tubing combination. From a stored menu, you select the pump tubing you have installed in the LabTec. For high accuracy dispensing applications, you may want to use the LabTec™ single-point re-cal feature. |
|
|
|
| 3. Organic Solvent Dispensing: Preparation of HPLC Mobile Phase and Extraction Solvents |
|
 |
|
| In this configuration, the LabTec solvent delivery system is a walkup
dispensing station. The user selects the solvent volume then
presses a front panel key or foot switch to initiate the dispensing cycle.
The LabTec provides high precision, high accuracy dispensing from
milliliters to liters. |
|
| The LabTec automates the safe and accurate dispensing of solvents
typically supplied in pressurized, stainless steel (SS) containers (i.e. J.T.
Baker CYCLE-TAINER). The closed, inert-gas-blanketed SS container and
Teflon fluid lines eliminate any solvent contamination and degradation. |
|
 |
The LabTec solvent delivery system maintains solvent purity while
reducing hazardous solvent waste. The LabTec controlled solvent
delivery system enhances employees’ safety by reducing solvent spills
and hazardous vapor exposures. |
|
|
| Volumetric dispensing accuracy is assured with a simple, single key
re-calibration feature. Alternatively, dispensing by weight eliminates
the need for pump calibration but will require hook-up to an electronic
scale. For ease of use, up to ten user-defined dispensing volumes can
be stored in the LabTec. All dispensing data are printed out or sent to
your PC for data archiving. |
|
|
4. Biopharmaceutical GMP Filling Application:
High Accuracy Dispensing with In-Line Filter Sterilization |
|
 |
|
| In this configuration, the LabTec is connected to an electronic scale
for high accuracy, GMP filling applications. A sterilizing filter and a
disposable pressure transducer provide a safe and effective in-line
filter sterilization capability. The LabTec continuously monitors the filter
backpressure and alarms when a user-defined pressure level has been
exceeded, which indicates a filter plug-up condition. |
|
 |
The high dispensing accuracy is achieved by reducing the pump rate
as the target weight is being approached. The slow-down avoids
overshooting the target weight. After slow-down, the LabTec pump
stops briefly when 99% of the final target weight has been dispensed.
The electronic scale is allowed to come to a steady-state readout and
the LabTec slowly starts up again to dispense the remaining solution. |

|
| Take advantage of SciLog’s liquid handling know-how. SciLog can provide
you with automated, customized liquid handling technology for laboratory,
pilot plant and production. Whether you need to fill syringes or aseptically
transfer solution into single-use storage bags, SciLog has the appropriate
system for you. |
