It is fully equipped to ensure safe and convenient dosing of fluids. The specifically designed piston makes drawing up and dispensing fluids from the Dispensette ® particu- larly smooth and ergonomic. The volume is set easily and fixed safely. The bottle top dispenser Dispensette ® has proven its worth in demanding permanent use, also with aggressive media. Three different models are available: Digital: The mechanical volume setting is easy to read and ensures accurate and reproducible volume control. Easy Calibration Technique for calibration adjustment in seconds without tools. A calibration flag indicates changes from factory settings Analog-adjustable: Rapid and safe volume setting with new internal scalloped track. Simple calibration ad- justment with supplied tool. Fixed-volume: For standard applications. Simple calibration adjustment with a supplied tool Ordering information/Items supplied: Dispensette ® S / Dispensette ® S Organic bottle-top dispenser, DE-M marking, with per- formance certificate, telescoping filling tube, recirculation valve and recirculation tube (optional), mounting tool and adapters of polypropylene. Calibrated to deliver (TD, Ex). Error limits according to the nominal capacity (= maximum volume) indicated on the instrument, obtained with instrument and distilled water at equi- librium with ambient temperature at 20°C, and with smooth, steady operation. The error limits are well within the limits of DIN EN ISO 8655-5. A = Accuracy, CV = Coefficient of variation. Model: Application: Dispensette ® S: Red color-code. Wide range of practical applications, ideal for dispensing aggressive reagents, including concentrated bases and acids such as H 3 PO 4 , H 2 SO 4 (with certain exceptions such as HCl, HNO 3 , HF, etc.), saline solutions, as well as many organic solvents. Dispensette ® S Organic: Yellow color-code. Ideal for dispensing organic solvents, in- cluding chlorinated and fluorinated hydrocarbons (e.g., trichlo- rotrifluoroethane and dichloromethane), acids like concentrat- ed HCl and HNO 3 (except HF), trifluoroacetic acid (TFA), tet- rahydrofuran (THF) and peroxides. 1 Dispensette ® S, Digital, DE-M marking Volume ml Graduation ml A P ± % CV P % without recirculating valve with recirculating valve Order No. Order No. 0.1–1 0.005 0.5 0.1 10 49 46310 10 49 46311 0.2–2 0.01 0.5 0.1 10 49 46320 10 49 46321 0.5–5 0.02 0.5 0.1 10 49 46330 10 49 46331 1–10 0.05 0.5 0.1 10 49 46340 10 49 46341 2.5–25 0.1 0.5 0.1 10 49 46350 10 49 46351 5–50 0.2 0.5 0.1 10 49 46360 10 49 46361 2 Dispensette ® S, analog-adjustable, DE-M marking Volume ml Graduation ml A P ± % CV P % without recirculating valve with recirculating valve Order No. Order No. 0.1–1 0.02 1.0 0.2 10 49 46100 10 49 46101 0.2–2 0.05 0.5 0.1 10 49 46120 10 49 46121 0.5–5 0.1 0.5 0.1 10 49 46130 10 49 46131 1–10 0.2 0.5 0.1 10 49 46140 10 49 46141 2.5–25 0.5 0.5 0.1 10 49 46150 10 49 46151 5–50 1.0 0.5 0.1 10 49 46160 10 49 46161 10–100 1.0 0.5 0.1 10 49 46170 10 49 46171 3 Dispensette ® S, fixed-volume, DE-M marking Volume ml A P ± % CV P % without recirculating valve with recirculating valve Order No. Order No. 1 0.5 0.1 10 49 46210 10 49 46211 2 0.5 0.1 10 49 46220 10 49 46221 5 0.5 0.1 10 49 46230 10 49 46231 10 0.5 0.1 10 49 46240 10 49 46241 choice of fix. vol. 0.5–100 — — 10 49 46290 10 49 46291 1) please state when ordering Volumetry Dosing Devices
