INTRODUCTION Please read all the information in this user manual before using the Sample Concentrator. The Techne Sample Concentrator has been designed to provide a quick and convenient method of accelerating the concentration by evaporation of solvents from samples prior to analysis. It is designed to work in conjunction with Techne DB-3, DB-3A or DB-3D Dri-Block® heaters*. The Sample Concentrator consists of a gas chamber mounted above a Dri-Block® heater into which vessels containing samples are placed.
SAFETY ADVICE BEFORE USE OPERATOR SAFETY All users of Techne equipment must have available the relevant literature needed to ensure their safety. It is important that only suitably instructed personnel operate this equipment, in accordance with the instructions contained in this manual and with proper safety standards and procedures.

Connect the intake nozzle at the rear of the gas chamber to a suitable supply of gas via a pressure reducing valve. The gas pressure should be adjusted as required at the reducing valve but should not exceed 2 psi. Pressure in excess of 2 psi will cause gas to be vented and wasted. 4.
GUARANTEE This instrument is guaranteed against any defect in material or workmanship for a period as specified on the enclosed guarantee card. This period is from the date of purchase, and within this period all defective parts will be replaced free of charge provided that the defect is not the result of misuse, accident or negligence. Servicing under this guarantee should be obtained from the supplier.
OPERATION Preparation 1. Place the aluminium insert blocks to be used into the Dri-Block® unit. The blocks should touch each other and be positioned centrally. 2. Loosen the locking knob on the carriage. Remove the gas chamber, disconnecting the gas pipe if necessary, and lay the chamber upside down on a suitable work surface. 3. Insert the hyperdermic needles in the pattern to suit the test tubes to be placed in the heater.

PROCESSING OF SAMPLES Warning - remember high temperatures are dangerous. The heater, insert blocks, sample vessels, needles and samples may be very hot. Always take the precautions listed earlier in this manual. 1. By turning the carriage handle, on the right hand side, counter clockwise raise the gas chamber to take the needles well away from the heater. 2. Place the sample vessels in the insert blocks and lower the chamber so that the tips of the needles enter the test tubes.
ADDITIONAL INFORMATION 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.
