Continued on next page 428 Dispensers 1 2 Bottle-Top Dispenser VITLAB ® simplex 2 , VITLAB Simple and safe handling have made this bottle-top dispenser so popular. 1 Bottle-Top Dispenser VITLAB ® simplex 2 Drawing quantities of liquids from large supply bottles is a daily routine in the lab. This manual task must be carried out quickly, accurately, reproducibly, simply and safely. VITLAB ® simplex 2 bottle-top dispensers are a family of instruments with proven precision that offer many advantages in routine liquid-handling operations. The positive displace- ment piston in this instrument is equipped with a fluoroplastic (PFA) sealing lip on the cylinder wall. This acts like a windscreen wiper to prevent crystal build-up on the cylinder wall from readily crystallisable media. The glass cylinder is also coated with a plastic material that reduces the risk of splashes should breakage occur. The telescopic filling tube can be adjusted smoothly to the height of the bottle. Since the materials in contact with the media (borosilicate glass, Al 2 O 3 ceramic, FEP, ETFE, PFA, PTFE, PP, platinum-iridium) are resistant to most acids, bases, and solvents, VITLAB ® simplex 2 bottle-top dispensers can be used in practically any operation. The VITLAB ® simplex 2 is completely autoclavable at 121°C (2 bar) according to DIN EN 285. Included in delivery: VITLAB ® simplex 2 with 3 respectively 5 threaded adapters made of PP. Nominal volumes of 2 – 10 ml (screw coupling GL 45) with adapters GL 25, GL 28, GL 32, GL 38, S 40 and telescopic intake tube length 125 to 240 mm. Nominal volumes of 25 – 100 ml (screw coupling GL 45) with adapters GL 32, GL 38, S 40 and telescopic intake tube length 170 to 330 mm. Mounting tool, instruction manual, and quality certificate stating all test values.
