CELLTREAT® 229025B 25mL Serological Pipet, Standard Length, Individually Wrapped, Paper/Plastic, Sterile — 200/Case

Product Description

The CELLTREAT® 229025B is a standard-length 25mL serological pipet individually wrapped in a paper/plastic wrapper and packed in bags — sterile, color-coded red, and manufactured to the ASTM Standard Specification for Serological Pipets E-934. Bi-directional (positive and negative) graduations are printed in bold, easy-to-read ink, and color-coded stripes and packaging enable quick volume identification at a glance. Each pipet features a premium material barrier plug for aerosol and contamination protection, and an anti-drip tip for accurate, clean delivery at 25mL volumes. Manufactured from USP Class VI medical grade virgin polystyrene — RNase-free and DNase-free. Sold in cases of 200, packed in bags of 50.

ASTM E-934 Manufactured — Meets the Standard for Serological Pipets All CELLTREAT serological pipets are manufactured to the ASTM Standard Specification for Serological Pipets E-934 — the defining standard for dimensional accuracy, volumetric performance, and graduation requirements for serological pipets. Compliance with ASTM E-934 ensures consistent, reliable volume delivery that meets the expectations of quality-controlled cell culture labs, molecular biology environments, and regulated research settings requiring documented consumable qualification for GMP or GLP work.

Anti-Drip Tip — Clean, Accurate Delivery at 25mL The CELLTREAT 229025B features an anti-drip tip specifically designed to prevent post-delivery dripping — a critical feature at the 25mL volume where a single unwanted drop represents a meaningful volume and where dripping can contaminate media, reagents, and cell culture vessels. The anti-drip tip ensures clean, precise dispensing every time, reducing waste and improving accuracy in routine cell culture and liquid handling workflows.

25mL Standard Length — Routine Cell Culture and Reagent Transfer The standard-length 25mL format is the workhorse for high-volume cell culture media addition and aspiration — ideal for T-75 and T-150 flask media changes, large reagent transfers, dilution preparation, and any application requiring volumes between 10mL and 25mL in a standard-reach format. Compatible with all major serological pipet controllers including the CELLTREAT ali-Q series, Corning Stripettor®, Integra VIAFLO, and all other commonly used controllers.

229025B vs. 229225B — Choosing the Right 25mL Format:

Bi-Directional Graduations — Positive and Negative Volume Delivery The 229025B features bi-directional (positive and negative) graduation markings printed in bold, easy-to-read ink — allowing the pipet to be read from either end of the scale. Positive graduations support standard delivery from full to empty, while negative graduations allow visual confirmation of volume remaining in the pipet during use — accommodating all common serological pipetting techniques and controller types.

Premium Material Barrier Plug — Aerosol and Contamination Protection Each 229025B pipet includes a premium material barrier plug positioned to prevent liquid aerosols from being aspirated into the pipet controller during use — protecting the controller from contamination and preventing cross-contamination between samples. The plug material is selected for compatibility with aqueous media, buffers, sera, enzyme solutions, and all other common biological laboratory fluids.

Color-Coded Red — Instant 25mL Visual Identification The 229025B is color-coded red throughout — the pipet stripe, wrapper, and bag packaging all carry the red color code universally associated with the 25mL serological pipet format. In active cell culture labs where multiple pipet volumes are in simultaneous use, the red color coding allows instant visual identification of the correct volume without reading the label — reducing errors and streamlining workflow at the biosafety cabinet.

Individually Wrapped — Sterile Packaging for Single-Use Applications Each pipet is individually wrapped in a paper/plastic wrapper and packed in resealable bags of 50 — maintaining sterility until the moment of use while keeping the remaining pipets in the bag clean, organized, and accessible. The paper/plastic wrapper format is compatible with all standard biosafety cabinet and clean bench workflows and is the most widely used serological pipet packaging format in cell culture labs worldwide.

USP Class VI Polystyrene — RNase-Free and DNase-Free CELLTREAT serological pipets are manufactured from USP Class VI medical grade virgin polystyrene and are certified RNase-free and DNase-free — meeting the material purity standards required for molecular biology, RNA work, and sensitive cell culture applications. All pipets are supplied sterile by gamma irradiation.
