How Many Steps Do You Need to Operate the Bottle-Top Dispenser?

Hawach bottle-top dispensers are liquid measuring devices, prevent spills to make our laboratory cleaner and safer. The bottle-top dispensers can attach to the top of the bottles which contain the liquid to be measured and make allow safe and accurate liquid distribution without contamination. Hawach bottle-top dispenser has a wide field of applications in biology, clinical, chemical, pharmaceutical, and forensic labs.

The air purging system on the bottle-top dispensers helps to avoid the loss of expensive reagents and media messes during liquid transfers. The nozzle can dispense liquids accurately into the receiving container easily. The right-angled spout of bottle-top dispensers does not require any cap to keep clean workspaces in your lab. You can find that the Hawach bottle top dispensing system is so innovative that it fits lots of laboratory chemicals including corrosive and flammable liquids and its most standard laboratory bottles.

To match your needs, Hawach bottle-top dispensers include mechanical bottle-top dispensers and electronic bottle-top dispensers. Both of them are safe and convenient with the volume regulation which makes your liquid distribution quickly and accurately. And the electronic control system on electronic bottle-top dispensers makes the process more stable and reliable.

Preparation before operation
Before use, please check whether the bottle-top dispenser is damaged or not. If there is a malfunction (such as difficulty in plunger movement or valve blockage), the liquid separation operation should be stopped immediately. Before use, please clean it according to the cleaning instructions or contact the manufacturer. Pls, note the bottle-top dispenser is made of polypropylene (PP) and can only be used to dispense liquids that do not react with PP materials.

Operation steps
Step 1 Connect the outlet tube
Do not use a non-standard dispensing tube; do not use a damaged or deformed outlet tube.
1. Tighten the liquid outlet valve with a tool
2. Insert the outlet tube as deep as possible into the outlet valve

Step 2 Connect the inlet tube
1. Tilt cut the inlet tube
2. Insert the inlet tube into the inlet valve as deep as possible so that the beveled side is at the bottom.

Step 3 Install Reagent Bottle
You can screw the thread directly or use the included adapter. Pls, note the adapter is made of polypropylene (PP) and can only be used to dispense liquids that do not react with PP materials.

Step 4 Liquid filling
Please note that when using a small reagent bottle, a holder should be used to prevent the reagent bottle from tipping over.
The reagent may drip from the outlet tube or protective cap.

Step 5 Dispensing
Follow the safety instructions and pay attention to the operating restrictions. The outlet tube must face away from the operator and others. Do not press down on the plunger when the protective cap is attached. The reagent may drip from the outlet tube or protective cap.

Step 6 Set the volume
Place a suitable collection container at the bottom of the liquid. Slowly and evenly pull up the plunger to the upper stop position and draw the reagent into the glass plunger cylinder. Slowly and smoothly push the plunger down to the lower stop position and dispense the reagent into the collection container. Please note that after use, always keep the plunger at the bottom position.

Step 7 Cleaning
The bottle-top dispenser must be cleaned to ensure proper operation in the following cases.
– Plunger movement is difficult
– after dispensing the liquid with precipitation
– before replacing the reagent
– after long time storage placement
– the liquid has been deposited at the protective cap
– before sterilization
– before replacing the valve
