Spills, cross contamination scares, and guesswork on volume often start with a rushed transfer. When your bench is stacked with samples, you need a pipette that fills fast, keeps a steady grip, and shows you exactly what you moved. Dynarex Large Bulb Transfer Pipettes do all three without slowing you down.
What Transfer Pipettes, Large Bulb Does for You
These disposable LDPE transfer pipettes are built for speed and control. The oversized bulb pulls liquid in quickly with a single squeeze, then lets you meter it out in a smooth, predictable stream. That means fewer splashes, fewer do overs, and far less hand fatigue during repetitive tasks like aliquoting, pour offs, or reagent additions.
The transparent barrel and molded graduation marks help you keep transfers consistent. You are not turning them into analytical pipettes, but you are gaining dependable, repeatable approximations that keep prep steps aligned across techs and shifts. When uniformity matters, those visible marks provide an instant reference you can trust shift after shift.
Chemically inert LDPE, free of DEHP, plays nicely with common lab fluids, clinical buffers, mild acids and bases, and routine diagnostic reagents. Since each pipette is single use, you cut cross exposure risk and eliminate the clean, dry, and wait cycle that bogs down throughput. You also get smart scale: 10 bags of 500, 5,000 total, so you can stage inventory at multiple benches, carts, or kits.

Add to CartWho This Is Perfect For
High volume clinical benches. Specimen intake and processing teams who need quick pour offs, aliquots, and reagent transfers will appreciate a bulb that draws fast without dribbling. The large capacity handles bigger volumes, so you spend less time squeezing and more time moving the workflow forward.
Mobile testing and outreach. When space is tight and contamination control is critical, disposables are king. Bagged sets of 500 travel easily in field kits, and LDPE flexibility means reliable performance even in less controlled environments like mobile clinics and pop up screening sites.
Education, training, and first aid stations. You get safe, predictable handling for demonstrations, classroom labs, and kit based specimen prep. Disposable format avoids sink time, and molded graduations help learners practice consistent transfers.
What Sets It Apart
Plenty of transfer pipettes exist, but most miss on either speed, grip, or consistency. This Dynarex option balances all three in a case built for real bench work. Four details make the difference:
Oversized bulb, faster draw
The large bulb creates strong suction with less effort, so you fill to working volume in one or two squeezes. That saves seconds on every transfer and reduces hand strain during repetitive tasks.
Molded, legible graduations
Graduations are molded into the barrel, not printed, so they remain visible over the life of the pipette. You get consistent, repeatable approximations that keep aliquots aligned across staff.
Secure, non slippery handling
LDPE provides a soft, grippy feel that is easy to control with gloved hands. One handed operation stays steady, which lowers the chance of slips that waste samples.
LDPE and DEHP free
Chemically inert LDPE, with no DEHP plasticizer, supports routine lab fluids and clinical reagents. It helps protect sample integrity and aligns with material preferences in many facilities.
Worth the Price?
A full case is 5,000 pipettes at $214.78. That is about $0.043 per pipette. At four cents each, you remove cleaning time, reduce contamination risk, and keep the line moving. If a technician saves just one second per transfer and performs 2,000 transfers in a week, that is roughly 33 minutes of labor recaptured. Multiply that across a team and the case pays for itself quickly.
Durability in the moment also matters. The soft, pliable bulb resists collapse and reexpands predictably, which helps avoid sample loss and rework. Molded graduations support consistent aliquots that prevent small errors from snowballing into repeat tests. Consistency is quiet ROI. It shows up as intact schedule blocks and fewer reruns.
Packaging efficiency adds value too. Ten inner bags of 500 let you stage inventory at multiple benches without opening the entire case. That reduces handling, keeps stocks clean, and cuts the scramble when a station runs low. You are buying simplicity that scales with your workload.
Speed, grip, and consistency in a disposable format. That is how you move more samples with fewer mistakes and lower stress.
Common Questions, Honest Answers
No. This model is non sterile and intended for everyday transfers where sterility is not required. For sterile technique, choose a sterile packaged option. If you need cleaner handling in a pinch, open a fresh pipette only when ready and avoid touching the stem end.
They provide consistent approximations for transfer work, not calibrated measurements. Use them to match volumes across samples or steps. For exact volumes and analytical accuracy, use calibrated pipettors, serological pipettes, or volumetric glassware.
LDPE generally works well with water based solutions, buffers, mild acids and bases, and many clinical reagents. Avoid strong oxidizers and aggressive organic solvents that can swell or degrade LDPE. Always confirm with your facility’s chemical compatibility chart for the specific fluid.
The Bottom Line
If you want faster transfers, better control, and cleaner workflows, Dynarex Large Bulb Transfer Pipettes deliver. Stock the 5,000 piece case, stage the bags where work happens, and keep your bench moving. Ready to kit up your stations now? Add this case to your cart and put transfer bottlenecks behind you.
