Tomos SL-Plus Autoclavable Adjustable Pipette -------------------------------------------------------------------------------- Magnetic Assistance A magnet reduces the need for a large weight difference between the aspiration and blowout springs. Both springs are therefore significantly lighter in the SL models. More Consistent Sample Pickup Tomos advanced magnetic system greatly improves pipetting accuracy and reproducibility in the SL pipettes. The plunger glides smoothly at every setting, ensuring precise aspiration every time. No Heavy Springs The magnetic system, low spring forces and low drag seals in the SL models reduce the force required to push the plunger. Comfortable, Ergonomic Handle; Small, Lightweight, Rugged Body The SL pipettes are lightweight with a small handle and conveniently-placed finger hook. Made of high-density, chemical-resistant polymer, they wont crack or break even if dropped. Comfortable Finger Hook The conveniently-placed finger hook allows the user to rest his hand and grip the pipette more lightly during use. The pipettes can be held in a variety of positions to further reduce repetitive strain. One-Handed Volume Adjustment Simply turning the plunger allows the user to adjust volume using only one hand. The snag-proof design allows rapid adjustment even with gloves on. Easy-to-read dials show volume in microlitres, greatly reducing the chance of error. Volume Lock A slight turn of the volume setting lock prevents accidental volume changes. Quick-Release Tip Ejector. Easy Maintenance
