Frequently asked questions for Pipette Bulbs & Laboratory Liquid Handling
What's the difference between safety bulbs and vacuum pressure bulbs?
Safety bulbs include protective features (like pipet guards) for one-handed operation and reduced spillage. Vacuum/Pressure bulbs provide both suction and pressure capabilities for more versatile liquid handling across different sample types.
Are Heathrow pipette bulbs compatible with all pipette types?
Heathrow bulbs work with standard glass pipettes. Check the bore size and tubing length specifications on our product pages to ensure compatibility with your equipment. Contact us if you're unsure about fit.
What's the difference between natural rubber and silicone fillers?
Natural Rubber Pipet Fillers offer standard performance for general lab work. Silicone fillers resist harsh chemicals and solvents better, making them ideal for pharmaceutical or chemical testing environments.
How do I know which capacity to order?
The capacity should match your pipettes. Smaller capacities (1-5mL) are for precise, small-volume sampling. Larger sizes (30-60mL) handle bulk liquid transfer. Review your equipment specs or contact our sales team.
Does Weber Scientific offer bulk pricing for lab procurement?
Yes. We offer multiple package options and provide organizational pricing. Sign in to your account or call 800.328.8378 for volume quotes.
