Product Description
LIGHT LABS is proud to offer the CELLTREAT Cell Scraper with Scraper Blade (Cat # 229310) — a premium, sterile, individually wrapped cell scraper engineered for the gentle, efficient harvesting of adherent cells from tissue culture flasks, dishes, plates, and bottles using a natural windshield wiper-style sweeping motion. The 229310 features a 25cm green ABS handle and a 20mm "Scraper" blade positioned parallel to the handle — enabling a smooth, back-and-forth sweeping motion across the flask surface that systematically covers the entire growth area with each stroke.
The parallel blade orientation of the 229310 Scraper is the most familiar and widely used cell scraper style — delivering broad, consistent coverage of the flask surface with each sweeping motion, making it the go-to choice for routine cell harvesting in standard-format tissue culture flasks and dishes. For researchers who prefer a raking or pulling motion that gets under cells and lifts them from the growth surface, the Lifter blade version (229311) is the ideal complementary product.
The scraper blade is constructed from soft, pliable TPE — specifically chosen for its flexibility and biocompatibility. Unlike rigid blade scrapers that can score or scratch polystyrene flask surfaces, the flexible TPE blade conforms to the contours of the flask bottom, ensuring complete cell coverage without surface damage while maximizing cell recovery and viability. The rigid green ABS handle (7mm handle diameter) provides comfortable, ergonomic grip with sufficient rigidity for efficient force transfer. Overall length: 25.1cm. Every scraper is certified nonpyrogenic, RNase-/DNase-free, and individually packaged in a sterile wrapper — providing single-use sterility assurance for contamination-sensitive cell culture workflows. Every case is printed with the lot number for quality traceability. LIGHT LABS is your trusted source for CELLTREAT laboratory plasticware.
KEY FEATURES
- 20mm Scraper blade positioned parallel to the handle — enables natural windshield wiper-style back-and-forth sweeping motion for systematic, complete coverage of flask growth surface
- Distinct from Lifter blade (229311) which is perpendicular to the handle for raking/pulling motion — choose based on your preferred harvest technique and cell type
- 25cm handle — standard length suitable for T-25, T-75, and smaller format dishes and plates; for larger T-150/T-182/T-225/T-300 flasks, see 39cm handle version (229315)
- Soft, pliable TPE (thermoplastic elastomer) blade — flexible blade conforms to flask surface contours without scratching or scoring polystyrene; outperforms rigid hard plastic blades of competing brands
- Green ABS handle (7mm diameter) — ergonomic grip with sufficient rigidity for efficient force transfer to blade tip; green color for easy product identification
- Certified nonpyrogenic, RNase-free, and DNase-free
- Sterile — gamma irradiated; individually wrapped in sterile wrappers for single-use contamination control
- Every case printed with lot number for quality traceability
- Overall length: 25.1cm; blade width: 20mm
- Fisher Scientific Catalog No. 50-201-974

BLADE TYPE GUIDE — CHOOSING THE RIGHT CELLTREAT CELL SCRAPER
| Blade Type | Position | Motion | Best For |
|---|---|---|---|
| Scraper (229310, 229315) | Parallel to handle | Windshield wiper/sweeping motion | Standard scraping across flask surface; routine cell harvest |
| Lifter (229311, 229316) | Perpendicular to handle | Raking/pulling motion | Getting under cells; lifting from surface; cell culture dishes |
| Narrow Scraper (229314) | Parallel to handle | Windshield wiper motion | Small-opening flasks (T-12.5, T-25, T-75) |
| Narrow Lifter (229313) | Perpendicular to handle | Raking motion | Small-opening flasks with lifting preference |

APPLICATIONS
- Adherent cell harvesting from tissue culture flasks (T-25 through T-75) using windshield wiper sweeping motion
- Cell detachment from tissue culture dishes and multi-well plates
- Enzymatic digestion-free cell detachment for sensitive cell types
- Cell viability-preserving harvest for flow cytometry, downstream assays, and cryopreservation
- Cell counting and subculture preparation from standard-format culture vessels
- Protein extraction and cell lysis protocols requiring complete cell removal from culture surfaces
- Routine cell passage and harvest in any adherent cell culture workflow
