User maintenance

1. Cleaning

Your Sample Concentrator can be cleaned by wiping with a cloth dipped in soapy water. Ethanol and

formaldehyde may also be used. Do not use abrasive cleaners.

2. Carriage friction

Height adjustment is by means of a friction drive. To allow for wear the friction pressure may be

increased by tightening the 4 screws on the rear of the carriage sufficiently to give adequate grip.

Ensure that all four are tightened equally.

3. To replace the sealing pad

After many repeated needle insertions the self sealing property of the sealing pad may start to

degrade. Spare pads can be obtained from your supplier or from Techne. Replacing the pad is simply

accomplished as follows:

• Remove the gas chamber from the carriage, disconnect the gas pipe and place upside down on a

suitable work surface.

• Remove the four nuts securing the matrix plate.

• Lift off the matrix plate leaving the four spacers in position.

• Lift off the sealing pad. Ensure that the support strip underneath the sealing pad and the four spacers

remain in place.

• Replace the sealing pad with the new one. Reassembly is the reverse of the above procedure.

For any other servicing requirements please contact your supplier or Techne’s service department.
