About Trouble-Shooting of the Bottle-Top Dispenser
As the most common instrument and equipment in the experiment, the bottle-top dispenser is suitable for general acids and bases, low concentrations of strong acids and alkalis, and salts. It enables accurate, highly repeatable dispensing operations without wasting reagents and meanwhile, it ensures the safety of the operator. However, some problems may arise during the operation. The following has summarized the most frequently FAQ and its solution. If these cannot solve your problem, welcome to contact the HAWACH after-sales team.
Bottle-top dispenser features
-Fast volume setting and precise scale design
-To make the operation convenient and comfortable, it installs smooth and precise piston sliding up and down
-Discharge tube safety helmet, which can avoid contact with reagents, even when wearing gloves, it can be easily installed or removed.
-Transparent pipette, suitable for reagent bottles of various sizes
-Strong chemical resistance
-Can be sterilized by high temperature
-Manual and electric bottle-top dispensers meet and cover the 0.1-99.9ml capacity range
-Convenient design ensures simple and economical cleaning and maintenance of the dispenser
-Made of optical glass, Al2O3, ETFE, PFA, FEP, PTFE, platinum-iridium alloy, PP (hard hat)
-Liquid reacting with ETFE, FEP, PEA, PTFE, Al2O3: sodium azide
-The liquid that corrodes optical glass: hydrofluoric acid (HF)
-Liquid of platinum-iridium alloy for catalytic decomposition (H2O2)
-Nicotinic acid, trifluoroacetic acid, tetrahydrofuran
-Explosive liquid: carbon disulfide
-Suspension: Carbon-containing solution
-Limiting solution: concentrated hydrochloric acid, nitric acid, chlorinated hydrocarbons, and fluorinated hydrocarbons, and liquids that can form deposits can cause piston stickiness or cause a blockage (such as crystalline or concentrated alkaline solutions).
