Eppendorf’s new Repeater M4 is the latest addition to the company’s handheld serial pipetting range, designed to minimize the time and effort required for precise and highly accurate repeat dispensing tasks.
The new Repeater M4 works with nine sizes of Eppendorf Combitips advanced®. A built-in sensor detects the Combitips automatically, showing the tip volume on an easy to read display and eliminating the need for manual volume calculations. In addition, the new central Combitip ejector supports one-handed operation for contact-free tip ejection that avoids any risk of contamination.
Since there are 20 volume settings for each of the nine Combitips, the Repeater M4 can dispense volumes from 1 µL to 10 mL and completes as many as 100 operations without refill. This is significantly more than similar handheld dispensers on the market. An integral step counter displays the number of steps executed, allowing the user to resume with confidence should there be any interruption while dispensing.
With the ability to conduct a maximum of 100 dispensing actions accurately and precisely, the new Repeater M4 is ideal for applications involving 96-well plates, for example. Based on the positive displacement principle it also eases the handling of viscous or volatile liquids and lowers the risk of contaminating the Repeater itself when dealing with radioactive, toxic or other hazardous materials. Unlike air cushioned pipettes, the Repeater M4 allows accurate and precise dispensing of difficult to handle viscous solutions as well as liquids with high vapor pressure. Repetitive dispensing procedures, such as those required in plate filling, aliquoting and kit usage, can be very time consuming, with ample opportunity for errors and inconsistencies. The new Repeater M4 provides a new, highly efficient solution for quick and safe dispensing that laboratories can rely on.
