3. General Description
The Techne Gelation Timer is the ideal instrument for accurate measurement and quality control for the gelation of
resin or adhesive based samples in the laboratory. Before leaving the factory each instrument is calibrated and
certificated. All models have digital timers, with the output time in 1 minute increments up to 9999 minutes, for the
1 RPM model (GT5), and in tenths of a minute up to 999.9 minutes, for the 10 RPM model (GT6). Accuracy of
indicated gelation time is ±2% at a specific temperature.
4. Preparation for Use – All models
4.1 Electrical Installation
Before connection please read and understand these instructions and ensure that the line supply corresponds to
that shown on the rating plate.
Voltage variants for these instruments are 230V 50Hz, 230V 60Hz, 120V 50Hz & 120V 60Hz. The power
consumption of each unit is 5W.
This unit is supplied with a mains lead which requires a rewirable mains plug to be fitted.
NOTE: Refer to the equipment’s rating plate to ensure that the plug and fusing are suitable for the voltage and
wattage stated.
The wires in the mains cable are coloured as follows:
The appropriate mains plug should be connected to the instrument BEFORE connection to the mains supply.
Should the mains lead need replacement a cable of 0.5mm to BS6500 & CENELEC HD21.5 should be used.
4.2 To use the Gelation Timer mount the instrument clamping post onto a suitable retort stand or
fixture at the desired height for operation. Ensure that the instrument is clamped firmly.
4.3 Screw the appropriate paddle to the end of the paddle connector on the sliding contact.
4.4 Connect the instrument to the electricity supply and switch on.
4.5 The instrument will perform an automatic self test at switch on. All segments will illuminate
momentarily before displaying a single ‘zero’ on the right hand side, a buzzer will sound and the
LED should illuminate green. The gelation timer is now ready to use.
5. Operation
5.1 Sample preparation.
The test requires about 100ml of sample in a container at least 38mm internal diameter. The top
of the paddle stroke should be not less than 32mm below the sample surface and the bottom of
stroke not closer than 13mm to the bottom of the container. Standard sample cups for use with
the instrument are available (catalogue number F7846).
5.2 Starting Gelation.
Having prepared the sample in the manner described, gelation time measurement can be started in one of the
following ways :5.2.1
If you want to set up your sample under the paddle, start reaction and gelation timer
Press the ‘start’ button once. This starts the timer incrementing, the LED will flash ‘Green’ and the paddle
will start to reciprocate (up and down).
When the sample has gelated to the extent that paddle movement is halted (circuit is closed), the timer
is stopped along with the paddle, the buzzer sounds and the display will alternate between the word
‘GEL’ and the indicated gelation time.
This is the normal gelation mode.
Alternatively, if you want to start the timer as soon as the sample reaction is started:
Press the ‘Hold’ button once as soon as the sample is mixed, the timer starts incrementing (as gelation
has started), the LED will illuminate ‘Red’, the paddle will reciprocate (up and down) and the display will
alternate between the word ‘HOLD’ and accumulated time.
If the paddle switch is closed in the ‘HOLD’ state the timer is not stopped and the paddle continues to
reciprocate. This allows you time to place the sample under the paddle and get ready for gelation
To commence gelation measurement once everything is set up, just press ‘Start’ button once and then
follow instructions shown above in 5.2.1
5.3 Accidental tripping during gelation measurement.
If the paddle is accidentally tripped during gelation, the timer can be restarted by pressing ‘Restart’ button once.
Note: that the timer is restarted from when it was stopped, therefore the elapsed time between stopping and
restarting the timer is not recorded.
5.4 Stopping during gelation measurement.
The instrument can be stopped during gelation by pressing the ‘Stop’ button once. The paddle stops
reciprocating, the LED is extinguished and the word ‘STOP’ is indicated on the display.
To restart the gelation process just press the ‘Restart’ button once.
Note: While in stop mode, the timer will continue to run, and when restarted will indicate actual gelation time.
However, if the ‘Stop’ button is pressed a second time, having just stopped it, the timer will reset and the
instrument will enter the ‘Hold’ state, (see 5.2.2 above).
