Rainin XLS+ multichannels feature a patented pushrod and push bar design that work together to assure even, highly responsive pressure on all eight or 12 channels. This innovative technology, along with elastomeric “wet” seals, contributes to the industry-leading channel-to-channel accuracy and consistency of Rainin multichannel pipettes.
Slamming and jamming have long been hallmarks of multichannel pipetting – getting all eight or 12 tips to stick and stay stuck can be a challenge. Not so with Rainin XLS+ multichannels equipped with the patented Rainin LTS LiteTouch System. LTS tips feature a thin internal seal and positive, shelf-like stop, so they seat and seal “like butter”! No strain, no pain, just an easy, perfect seal on every channel (and the tips eject as easily and effortlessly as they mount)
This just-published paper is the definitive guide to obtaining higher quality, more repeatable serial dilutions. Few experiments challenge your pipette and the quality of your technique like a serial dilution. For one, errors accumulate, so a mistake made early in a serial dilution is amplified with each successive step.
This new paper goes beyond how to and technique, discussing the factors that affect serial dilutions, optimal working ranges, uncertainty and error propagation and the effect of tolerance in serial dilution.
