From 1961 introduced the first industrial gas piston pipettes far, Eppendorf company adhering to nearly 50 years of production experience and dedication to adhere to high quality, innovative research and development, clinical research is designed to provide users worldwide the most perfect pipetting device. Eppendorf Research? Plus finally, Research plus pipette birth, for now pipetting industry established a high standard. New Research plus pipette using high-tech materials with advanced production process, its ergonomic design, coupled with user-friendly operation applications, not only high accuracy, durability, while applicable to all types of experimental operation. Research plus> Pipettes ergonomic design, light weight, and operate a small force, the hand can effectively prevent repetitive strain injuries (RSI). The front end of the nozzle has the flexibility, not only can install and detachable tip more effort, but also to ensure the tightness between the tip and the pipette. Especially for multi-channel pipette tip can ensure consistent position to ensure the consistency of pipetting. Research plus pipette using high-tech materials, chemical corrosion resistance, high temperature, at the same time, you can support the entire UV sterilization and autoclaving. Unique density adjustment feature that allows Research plus pipette inconsistent with the density of liquid water. Pipette disassembly and maintenance is also very convenient. Multi-channel pipette can be adjusted manually to meet different consumables pitch. Product Features: Using high-tech materials PerfectPiston system, durable, high temperature corrosion can be a whole branch autoclavable and UV sterilization operation more secure four-digit volume display, reasonable location, easy to observe human excellence when pipetting? engineering design, light weight, a significant reduction in operating force, to avoid repetitive strain injuries hands (RSI) retractable elastic nozzle design, installation tips to prevent jagged, tightness and pipetting to ensure uniformity of density adjustment Eppendorf functions for liquids of different densities, versatility alone broader piston design, each channel individually removable, easy to maintain and clean channel digital identity, ensuring the same direction single channel pipette Eppendorf Reference pipettes 2500ul fixed range brands: Germany Eppendorf Overview: Eppendorf Reference Series piston pipettes in addition to a smooth, compact and rugged design, operating comfort, but also a symbol of precision pipette, the single multifunction button can pipetting, liquid shot, can also be detachable suction head operation. Reference series provides from 0.1 μl to 2,500 μl range of nine kinds of adjustable pipette range; also offers 16 kinds of fixed range of pipettes, pipette its scale range from 1 μl to 2,500 μl. Product Features: "pipette / tip" system ensures superior accuracy and precision pipette detachable bottom sleeve; after detachable detachable tip function will fail piston moves smooth, durable and chemically resistant new materials, entire branch autoclaving, UV-resistant treatment, and does not affect pipette accuracy and precision using accessory tools, convenient for simple maintenance to provide relevant guarantee one-hand adjustable volume pipettes adjustable for different densities of liquid Technical parameters: Range Accuracy Accuracy 1 μl ± 2.5% ≤1.8% 2 μl ± 2.0% ≤1.2% 5 μl ± 1.5% ≤0.8% 10 μl ± 1.0% ≤0.5% 20 μl / 25 μl ± 0.8% ≤0.3 % 50 μl ± 0.7% ≤0.3% 100-2,500 μl ± 0.6% ≤0.2% liquid: distilled water temperature: 20-25 ° C, ± 0.5 ° C measurement times: 10 times, using the original Eppendorf pipette tips, according to EN ISO 8566 standard
