Manual bottleneck distributor

1. LBTDispens Bottle-Top Dispenser complies with ISO 8655 calibration standards and delivers outstanding dispensing precision and accuracy. It is widely used in pharmacology, biotechnology, healthcare, food & beverage, chemistry, environmental monitoring, academic and research laboratories.
2. Four volume ranges are available: 0.5–5mL, 1.0–10mL, 2.5–25mL, 5.0–50mL. Volume adjustment is easy; the piston moves smoothly to enable labor-saving dispensing.
3. The drain tube is fitted with a safety cap to protect operators from direct contact with chemical reagents. A variety of bottle adapters are provided to fit most standard reagent bottles.
4. Wetted components are made of PTFE, FEP, borosilicate glass and PP with excellent chemical resistance. All liquid-accessible parts can be autoclaved at 121℃.
5. The unit can be easily disassembled and cleaned for regular maintenance. Main popular adapters are supplied as standard; optional accessories include filling tubes, discharge tubes and brown reagent bottles.

1. Excellent chemical resistance; inert high-strength wetted components made of PTFE, FEP, borosilicate glass and PP.
2. All liquid-accessible parts can be fully autoclaved at 121℃.
3. Four dispensing volume ranges covering 0.5mL to 50mL.
4. Easy to disassemble and clean for periodic maintenance.
5. Main popular adapters included as standard: S40, GL32, GL38, GL25, GL28.
6. Simple volume adjustment with clear scale for fast target volume setting.
7. Smooth piston movement reduces fatigue during repeated dispensing work.
8. Safety cap on discharge tube prevents reagent splashing and operator exposure.
9. Rich optional accessories including filling tubes, extended discharge tubes and brown light-proof reagent bottles.

1. LBTDispens bottle-top dispenser mounts directly onto reagent bottles to avoid repeated liquid transfer and reduce contamination & evaporation risk.
2. Compliant with ISO 8655 international standard for volumetric instruments. Max systematic error ±0.5%, random error ±0.2%, ideal for quantitative dispensing in precision experiments.
3. Inert chemically resistant materials compatible with most inorganic acids, salt solutions, buffers and organic reagents (not suitable for highly corrosive hydrofluoric acid).
4. Wetted components can be disassembled and autoclaved to prevent cross-contamination in cell and microbiology experiments.
5. Interchangeable bottle adapters fit GL thread bottles and S40 standard reagent bottles.
6. Discharge safety cap prevents reagent evaporation, dripping and accidental splashing when dispensing stops.
7. Smooth piston movement suits high-volume continuous dispensing and reduces operator fatigue.
8. Optional extended discharge tubes enable direct liquid addition into deep or narrow-neck vessels.
9. Optional 1L brown amber reagent bottle for long-term storage and dispensing of light-sensitive compounds.

1. Select volume range according to daily dispensing volume; choose model where target volume sits in the middle range for best accuracy.
2. Micro dispensing (0.5–5mL): LBTD-5ML; medium volume (1–10mL): LBTD-10ML.
3. Medium-large dispensing (2.5–25mL): LBTD-25ML; large-volume dosing (5–50mL): LBTD-50ML.
4. Confirm thread specification of existing lab reagent bottles and select matching GL/S adapters.
5. Light-sensitive reagents: add optional 1L amber brown reagent bottle (17400037).
6. Liquid addition into deep or narrow vessels: select matched extended discharge tube assembly.
7. Sterile workflow required: this autoclavable bottle-top dispenser is preferred.
8. Wide variety of chemicals: check reagent compatibility; not suitable for HF and aggressive fluorine-containing reagents.
9. Complete export packages: combine main unit + common adapters for one-stop delivery to end customers.
