DispensMate Bottle-Top Dispenser

1. SAFETY PRECAUTIONS

• Personal Protective Equipment (PPE): Always wear appropriate PPE when using the bottle‑top dispenser, including chemical‑resistant gloves, safety glasses or a face shield, and a laboratory coat, especially when handling hazardous, corrosive, or toxic reagents.

• Discharge Tube Direction: Always point the discharge tube away from yourself and others when dispensing. Never dispense directly toward the operator, as splashes or aerosol generation could cause severe injury.

• Check for Damage Before Use: Inspect the dispenser before each use. Do not use if the piston is difficult to move, if valves are sticking, if there is visible cracking or damage, or if leakage is observed. Stop dispensing immediately if any malfunction is detected.

• Do Not Force the Piston: Use smooth, gentle movements to operate the piston. Forcing the piston can damage internal components, cause inaccurate dispensing, or cause the reagent to splash.

• Never Press the Piston When the Screw Cap Is Pushed On: Pressing the piston while the screw cap is closed can pressurize the bottle and cause the reagent to spray out when the cap is opened.

• Do Not Remove the Discharge Tube When the Cylinder Is Filled: Removing the discharge tube while the cylinder contains liquid can cause reagent to spill uncontrollably.

• Secure Small Bottles: Always place small reagent bottles in a stable bottle stand or heavy‑base holder to prevent tipping over during operation.

• Carry by the Bottle, Not the Dispenser: When moving a mounted dispenser, always carry it by the reagent bottle, not by the cylinder sleeve or the valve block. Carrying by the dispenser can cause breakage or loosening of connections, leading to chemical spills and personal injury.

• Use Only Genuine Parts: Use only accessories and spare parts supplied by the original manufacturer. Do not attempt to make any technical alterations to the instrument.

• Observe Operating Limitations: The dispenser is designed for dispensing liquids only. Do not use with liquids that exceed the maximum vapor pressure (500 mbar), viscosity (500 mm²/s), temperature (40 °C), or density (2.2 g/cm³). Do not use with liquids that attack the wetted materials or with explosive liquids, suspensions, or highly crystallizing solutions.

• Avoid Static Discharge When Dispensing Flammable Solvents: When dispensing flammable media, avoid the buildup of static charge. Do not wipe the instrument with a dry cloth, and do not dispense into plastic vessels. Ensure proper grounding of the reagent bottle and work area.

• Do Not Carry or Transport with Reagent in the Cylinder: When transporting the dispenser from one location to another, ensure that the cylinder is empty to prevent accidental discharge of reagent.

• Training Requirement: Only trained laboratory personnel should operate the DispensMate Bottle‑Top Dispenser for clinical diagnostic or research applications. Users must read and understand the operator's manual before first use.

2. FIRST AID MEASURES

• Chemical Splash to Eyes: If a reagent splashes into the eyes, immediately flush the eyes with copious amounts of water or sterile saline for at least 15 minutes. Hold the eyelids open to ensure thorough rinsing. Remove contact lenses if present and easily removable. Seek immediate medical attention.

• Chemical Splash to Skin: Remove contaminated clothing immediately. Flush the affected skin area with cool running water for at least 15 minutes. Do not rub or scrub. Seek medical evaluation for chemical burns or if irritation persists. Refer to the Safety Data Sheet (SDS) for the specific chemical involved.

• Inhalation of Chemical Vapors: If vapors from volatile reagents are inhaled, move the affected person to fresh air immediately. Keep the person warm and at rest. If breathing is difficult, administer oxygen if trained. If breathing stops, perform CPR. Seek immediate medical attention.

• Ingestion of Chemical Reagent: If a chemical reagent is ingested, do not induce vomiting unless directed by medical personnel. Rinse the mouth with water. Seek immediate medical attention and provide the SDS or chemical name to the attending physician.

• Broken Glass Injury: If the glass cylinder breaks and causes a cut, allow the wound to bleed freely to flush out any contaminants. Wash the wound with soap and water for 15 minutes. Apply antiseptic and a sterile bandage. Seek medical evaluation, especially if the cut is deep or if the glass was in contact with hazardous chemicals.

3. FIRE FIGHTING MEASURES

• Flammability: The plastic components (PTFE, FEP, PP) are combustible and will burn if exposed to flame or high heat. The borosilicate glass cylinder is non‑flammable. The primary fire hazard is the flammable reagents being dispensed (e.g., organic solvents such as acetone, ethanol, hexane).

• Extinguishing Media: Use carbon dioxide (CO₂), dry chemical (ABC class), or alcohol‑resistant foam extinguishers for fires involving the dispenser or nearby flammable reagents. Do not use water on chemical fires unless specifically appropriate for the reagent involved.

• Fire Response: In case of fire, immediately turn off any nearby heat sources. Evacuate the area. Use an appropriate fire extinguisher for small, contained fires. For larger fires involving bulk solvents, evacuate the laboratory and call emergency services. Do not attempt to extinguish a fire if not trained or if the fire is spreading rapidly.

Special Protective Equipment for Firefighters: Firefighters should wear self‑contained breathing apparatus (SCBA) and full structural firefighting gear when fighting fires in laboratory settings, as combustion products may include toxic fumes from burning plastics and chemicals.
