The bottle-top dispenser makes liquid dosing easy and secure.Analog volume displayQuickly adjustable dosing volumeVolume selection with interior scalloped trackSimple calibration adjustment with a supplied toolValve system - tight sealing without additional sealing ringsFilling valve, olive-shapedAutoclavable at 121 °CScope of supply:Bottletop dispensers Dispensette® S, DE-M marked, performance certificate, telescope filling tube, mounting tool, adapters made of PPYellow color code. Ideal for dispensing organic solvents, e.g., chlorinated and fluorinated hydrocarbons such as trichlorotrifluoroethane and methylene chloride, or concentrated acids such as HCl and HNO3 (not HF) as well as trifluoroacetic acid (TFA), tetrahydrofuran (THF) and peroxides.
The combination of a springless PTFE valve and PTFE piston with chemically resistant ETP O-ring enables dispensing of both organic reagents as well as bases, thus, eliminating the need to buy different dispensers for different applications. The improved design of the uniTOPDISPENS 2 bottle top dispenser including a re-circulation valve allows a smooth, precise and reliable bubble free dispensing without any loss of reagent. The specially designed bottle adaptor which permits a 360° rotation of the unit, the easy volume setting as well as the flexible delivery nozzle underline the user friendliness of this bottletop dispenser. Available in six volume ranges.Springless PTFE valve, PTFE piston with chemically resistant ETP O-ring enables high chemical compatibility Glass cylinder from borosilicate glass 3.3Re-circulation valve enables easy priming and bubble free dispensingSmooth, reproducible and effortless dispensing360° rotation possible due to specially designed bottle adapterFlexible and adjustable delivery nozzle provides dispensing angle flexibility to the userSpecially designed volume adjustment knob for quick and easy volume settingThe telescopic extractable intake tube can be easily adjusted to varying bottle heightsNozzle cap reduces contact with air and prevents drying and dripping if the tip cover is attachedFive bottle adaptors included (28 mm, 32 mm, 37 mm, 40 mm and 45 mm). Standard thread: 30 mm.Fully autoclavable at 121 °C, 15 psi for 10 to 15 minIndividually calibrated in accordance with ISO 8655 standards and each unit is supplied with an individualcalibration certificateYou can find the appropriate compatibility list on www.llg-labware.com in the Downloads section.3 years warranty
