A rushed run, a contaminated tip, and a tiny drip that shifts your endpoint. You lose a full batch and an hour you will not get back. If your liquid handling is not sterile, accurate, and repeatable, the rest of your workflow pays the price.
What Serological Pipettes, Sterile, Individually Packed Does for You
These Dynarex LabChoice Serological Pipettes give you reliable 2 mL transfers with the kind of control that keeps protocols tight. Each pipette arrives gamma sterilized and individually pouched, so sterility is protected from warehouse to workbench. You open one when you need it, then move straight to the sample without guessing what might have touched the tip.
An integrated aerosol barrier plug helps prevent cross-contamination and protects your pipette controller from splashback. That barrier matters when you are moving biologicals, reagents, or QC standards. It is a simple safeguard that lowers the chance of carryover and keeps your controller internals cleaner for longer.
Clarity and accuracy come built in. Transparent polystyrene lets you see meniscus and particulates at a glance, and the reverse and negative graduations support precise dispensing, partial withdrawals, and blow-out techniques. Anti-drip tips help you release exactly what you intend, not a microliter more. The shafts fit most standard pipette controllers, so these drop right into daily use without forcing a change in your tools or training.

Who This Is Perfect For
Hospital and clinical labs: If your team mixes controls, prepares dilutions, or portion-doses reagents across analyzers, a clean, single-use pipette prevents cross-traffic between specimens. Individually pouched units make it easy to stage at benches, satellite stations, and clean rooms while preserving sterility until the moment of use.
Point-of-care and field teams: In mobile clinics, EMS support, or pop-up screening sites, dust, humidity, and traffic raise contamination risks. Individually packed pipettes shield the working end from the environment, then open fast when you are ready. Anti-drip tips help when you do not have the luxury of a vibration-free bench.
Research, teaching, and QA labs: Training days and validation runs depend on repeatability. The clear graduations and color-coded design speed student orientation and supervisor checks, while the aerosol barrier reduces the chance a trainee pulls contamination into the controller. The consistent molding and transparent walls make it easier to teach proper meniscus reading and endpoint control.
What Sets It Apart
On paper, a serological pipette is a simple tool. In practice, tiny design choices decide whether you trust the result. This model focuses on sterility, readability, and control, so you spend less time reworking and more time advancing the task at hand.
Aerosol barrier plug
The built-in barrier reduces the risk of aerosol carryover into your controller. It adds a layer of protection when handling biological samples or volatile reagents, and it helps your controllers stay cleaner between maintenance cycles.
Reverse and negative graduations
Graduations are easy to see and support precise partial dispensing and blow-out techniques. You can approach a target, make small corrections, and document volumes with confidence during protocols that require stepwise additions.
Anti-drip precision tip
A clean break at dispense minimizes tailing and unintended extra volume. That means fewer over-deliveries, less waste of expensive reagents, and tighter adherence to your SOPs during repetitive tasks.
Sterile, DEHP free materials
Each pipette is gamma sterilized and individually wrapped to maintain sterility to the point of use. Made from transparent polystyrene with a PET filter element, and DEHP free, they support a wide range of clinical and research applications.
Worth the Price?
Look at total cost of quality, not just unit price. This case contains 500 pipettes, which puts your cost near $0.29 per sterile, individually packed unit. One avoided repeat run or a single protected controller easily repays that. Anti-drip tips and clear graduations reduce reagent waste and failed checkpoints, which is where budgets silently leak.
Packaging matters too. With one pipette per pouch and easy color cues, inventory control is simpler. You can stage the exact number of sterile units for a shift and keep the rest sealed. That reduces open-box exposure and keeps audits straightforward. Compatibility with most controllers means you do not have to buy new hardware to start seeing the benefits.
Durability in daily use shows up as fewer mishandled doses, fewer contaminated lines, and fewer reset runs. These pipettes are designed to help you hit your mark on the first attempt. That is the value you feel every day, not just the day you place an order.
Precision you can see, sterility you can prove, and a per-use cost that pays for itself in fewer repeats.
Common Questions, Honest Answers
Yes. These are standard serological pipettes designed to fit most manual or motorized pipette controllers with a standard nosepiece. They are not for micropipettors that use small disposable tips. If your controller accepts common serological shafts, you are set.
Each pipette is gamma sterilized, then sealed in an individual pouch. Open only when ready to use, and discard after a single task. The aerosol barrier plug provides added protection against splashback and carryover. Follow your facility SOPs for sterile handling and documentation.
No. These are single-use polystyrene pipettes and are not autoclavable. Use one per procedure, then dispose of it according to your biohazard or chemical waste policy. Single-use control is a key reason these deliver consistent results.
The Bottom Line
If you want cleaner runs, tighter endpoints, and fewer do-overs, upgrade to a sterile, individually packed serological pipette you can count on. This 2 mL format drops into your current controllers and immediately removes friction from your workflow. Order a case today and put precision on your side.
