Los aus 2 Trockenbad/Heizblock Techne DB-3 (FDB03OP)

Lot of two Techne Dri-Block DB-3 analogue dry bath heating blocks (model FDB03OP), each fitted with a Techne Sample Concentrator. The DB-3 is a three-position benchtop dry block heater that uses interchangeable machined aluminium insert blocks as the heat transfer medium, giving a dry, constant-temperature source for general heating and incubating work as well as sample preparation and analytical procedures. Temperature is set from a front-panel analogue dial, which on these units is graduated from roughly 25 to 100 degrees C, and three front-panel indicator lamps show mains power, heater action and over-temperature cut-out.

Both units are rated 115 V, 50/60 Hz, 5.6 A, 650 W and carry CE marking on the rear nameplate (serial numbers 136631-14 and 147776-30). Each unit sits on a bench with a Techne Sample Concentrator mounted on a vertical rack-and-pinion stand behind it; the concentrator manifold carries a row of gas needles that is raised and lowered over the block positions for evaporative concentration of samples under a nitrogen or air stream.

Insert blocks are present in the photos: the first unit (photo 2) has three aluminium insert blocks installed covering all three positions, with well patterns of 20, 20 and 20 tube openings visible. The second unit (photo 3) has one 12-hole insert block fitted and its two remaining block positions open. The second unit also shows an obscured (marked-over) identification label and hand-written notation on the front panel and casing.

Condition is as-is, used laboratory equipment removed from a biopharmaceutical facility; operation was not verified and no accessories beyond what is visible in the photographs are included.
