Power

Power consumption 620W

The units are voltage selectable by a slide switch. When the unit is set to 115V it will work at any
voltage between 110V and 130V. When the unit is set to 230V it will work at any voltage
between 198V and 252V.
Units marked 100V will work at any voltage between 90 and 110V.
The performance will vary and will not necessarily meet the above typical specification at the
extremes of voltage.

20

USER OPERATION AND CONSUMABLES

HEATED LID

To release the heated lid, lift the back of the handle as shown and use it to lift the lid. To close the lid,
lower the lid onto the block containing the samples and press the handle down to shut.

The silicone rubber mat supplied with the unit (Part No. 6104978) is for use with microplates when
sealing using a plastic adhesive film. The mat should be placed on top of the sealing film to ensure good
thermal contact with the heated lid.

The heated lid has a rotating knob to adjust the lid pressure on the samples, allowing for a variety of
consumables to be used. To adjust the pressure:

1. Place the samples in the block and place the
lid in the down position.

2. Adjust the orange rotating knob
anticlockwise to give the least pressure then
close the lid fully.

3. Gently rotate the knob clockwise until you
can feel pressure beginning to be applied.

4. Rotate the knob a further quarter of a turn
and this will give the correct pressure.

Do not over-tighten the knob as this will cause deformation of the silicone rubber membrane (where
used) and reduce the effectiveness of the lid. Once the pressure has been set it does not need to be
adjusted unless a different block or consumable is used.

21

TUBES OR REACTION VESSELS

Techne does not recommend any specific tube or reaction vessel other than those described in this
manual. We recommend using reaction volumes between 20 and 200µl. The tubes must withstand a
pressure of 1 atmosphere at 100°C. Any vessel must be able to withstand the temperatures you are using
without any danger of them deforming to the point where they fracture.

To test your tubes, put 25µl of water into each of 5 tubes and subject them to a typical thermal cycling
protocol. At the end of the program, measure the volume remaining using a micropipette. A loss of more
than 1 or 2µl indicates a vapour leak.

The amount of volume loss you observe and the change in reactant concentrations you can tolerate
determine the minimum volume that can be used. Typical volume losses of 1µl in 30 cycles allow the use
of samples of 20µl or less.

During the final cool-down, a ring of condensation may form above the liquid level but below the top of
the sample block. This is normal and does not effect the reaction.

USER MAINTENANCE

CLEANING YOUR TC-412

Before cleaning your unit, disconnect from the power supply and allow to cool to below 50ºC. The
heating/cooling block, including wells and flat surfaces, should be cleaned regularly to ensure optimum
heat transfer to the samples. Always clean the block if there has been a spillage. Use a cloth or cotton
buds dipped in a fresh, 50:50 water/isopropanol solution and make sure that no deposits are left in the
wells.

In the case of radioactive spillages the heater block can be removed from the unit for more detailed
cleaning. Techne recommends that you use a proprietary cleaning agent and follow the manufacturer's
instructions. The heating/cooling block is made of aluminium, therefore an agent such as Neutracon
(from Decon Labs Ltd.), suitable for nonferrous metals should be used. However, remember that other
parts of the unit are made of ferrous materials and may be damaged by spillage onto them.

The case of the TC-412 may be cleaned with a cloth dipped in water or ethanol (methanol or
formaldehyde can also be used). No part of the case or cover should be immersed in the solvents. Do not
use aggressive solvents such as acetone or abrasive cleaners.

Before using any cleaning or decontamination method except those recommended here, the responsible
person should check with Techne that the proposed method will not damage the equipment.

45

BLOCK REMOVAL

Before removing the block, disconnect from the power supply and allow it to cool to below 50°C.

●

Slide the quick release handles in the
direction of the arrows indicated and lift the
block assembly out of the unit.

●

Never lift or carry the block by one quick
release handle, always use both handles or
support the block from underneath.

●

When re-fitting the block, or fitting a new
one, slide the quick release handles in the
opposite direction to lock the assembly into
the unit.

●

Open or closed padlock symbols are printed
on the quick release handles for easy
reference.

FREQUENTLY ASKED QUESTIONS

Q1 What is the 'Pause' function at the start of the program used for?

A1 Some users prefer to preheat the heated lid before placing the samples into the unit. The pause

feature is used to stop the unit after the 4 minute heated lid preheat step. It will also sound an
audible alarm indicating that the machine is ready for the sample tubes or plate to be added.
Pressing the "Pause" key followed by the "Enter" key will commence the remaining program.

Q2 Why do you have to press some keys twice to make the unit do what you want it to do?

A2 With many of the program features there is a fail-safe function which asks if you are sure you want

to perform a particular action. You are required to press one key to select a function followed by a
second to accept it.

Q3 What is 'Hot Start'?

A3 A "hot start" is used for reducing non-specific product formation during the first cycle of

amplification. The 'Hot Start' programming step is used to pause the instrument at a specific
temperature, typically around 70ºC, after the initial template denaturation. The reason is to allow
the manual addition of unmodified Taq DNA polymerase which may loose activity if added during
the initial 5min denaturation. Heat-activated Taq or Hot Start enzymes do not require this step.

Q4 What is the incremental function?

A4 Incremental timing and temperature are used to increase or decrease either the time or temperature

incrementally over the number of cycles in a stage.

46

Incrementation of extension time is used with 'Long PCR' which is when large template fragments
are to be amplified (e.g. 27kb lambda DNA, 40kb genomic DNA).

Decremental temperature is used for protocols such as 'Touchdown PCR' where one starts with a
high annealing temperature in the first cycle and gradually decreases the temperature over the
number of cycles in the stage. This ensures that only the specific product is amplified.

Q5 What is the appropriate pressure of the heated lid?

A5 The lid will need to be adjusted for the height of each different type of consumable used in the

unit. Firstly, with the lid in the down position, turn the orange rotating knob anticlockwise until it
will not go any further. Next with the tubes or plate in the unit, lock the lid and turn the knob
clockwise until pressure on the tubes or plate is just felt; then rotate another quarter turn. Do not
over-tighten.

ADDITIONAL INFORMATION

Brief fault finding notes and a list of replacement parts are given in this section.

Note that this equipment should only be dismantled by properly trained personnel. Removing the outer
cover exposes potentially lethal mains voltages. There are no user serviceable parts within this equipment.

FAULT FINDING

Should you have any problems with your TC-412 which cannot be easily remedied, you should contact
your supplier and return the unit if necessary. Please include details of the fault observed and remember
to return the unit in its original packing. Techne accepts no responsibility for damage to units which are
not properly packed for shipping: if in doubt, contact your supplier, giving the full serial number of the
unit and software version number (shown when the unit is first switched on).

FUSES

If neither the power light nor display on the front panel is lit, one of the two fuses may have blown.
Check that there is no external cause, such as a faulty plug or lead. Check both fuses and replace the
faulty fuse with a new one of the correct value (fuse values are given on the label next to the power inlet).
Note that fuses should only be replaced by a qualified electrician.

The holder for the two fuses is built into the mains input socket. First remove the power cable and then
gently prise the fuse drawer open with a flat-bladed screwdriver or similar tool.

Each fuse can be removed by using the screwdriver as a lever.

47

Exchange the faulty fuse in the fuse holder for a working fuse of the correct value. Finally, replace the
fuse drawer in the fuse compartment and push the drawer shut.

Fuses which blow repeatedly indicate a serious fault and you should return the unit to your supplier for
repair.

THE HEATED LID OVER-TEMPERATURE CUT-OUT

The heated lid is fitted with an independent circuit to protect it from overheating. In the unlikely event
of an over-temperature problem with the lid, the unit is fitted with a thermal fuse which will remove
power to the heater plate should the maximum temperature be exceeded.

INSULATION TESTING

This equipment is fitted with RFI suppression circuitry. Any check of the electrical insulation by means of
high voltage dielectric testing (for example as in BS EN 61010-1) must be carried out using only a DC
voltage.

This unit contains semiconductor components which may be damaged by electric field effects.

INTERCHANGEABLE BLOCKS

The block can be removed and replaced by another of the same sort or of a different sort. The software
will register the change and set up the unit for the new block.

Before removing the block, disconnect from the power supply and allow it to cool to below 50°C.

●

Slide the quick release handles in the
direction of the arrows indicated and lift the
block assembly out of the unit.

●

Never lift or carry the block by one quick
release handle, always use both handles or
support the block from underneath.

●

When re-fitting the block, or fitting a new
one, slide the quick release handles in the
opposite direction to lock the assembly into
the unit.

●

Open or closed padlock symbols are printed
on the quick release handles for easy
reference.

●

Remember to adjust the options in the
Options menu for the new block.

If you have fitted a flat block for slide applications, you must set the heated lid to OFF.
