Combined with state-of-the-art wet seals, corrosion-resistant tip ejectors and liquid ends that can be autoclaved, the XLS+ is an ergomonic pipette that performs all day without causing hand fatigue. It is easy to dispense accurate microliter volumes with a minimum of effort, even while wearing gloves. The snag-proof lock design prevents accidental volume drift and provides maximum security when resetting the dispensed volume.
XLS+ is equipped with a smart electronic display that can store multiple protocols on board, making it simple to program complex pipetting routines. Its large color screen and joystick control make operation easy and intuitive. In addition, the XLS+ is fully GLP/GMP compliant and can be password protected to ensure security.
The XLS+ is also built for smooth autoclaving where it counts – the entire liquid end, including the shaft and wet seals can be autoclaved without compromising performance or feel. The XLS+ is also the first pipette to feature an embedded RFID tag for tracking calibration, service records and cycle data.
The LiteTouch nozzle and tip design makes mounting multichannel tips remarkably easy, and allows for perfect sealing each time, without rocking or hand-tightening. And XLS+ multichannels are the fastest pipettes in their class, allowing you to move samples quickly and accurately. And with an extremely low ejection force, the XLS+ minimizes sample loss and maximizes your throughput.
R-100 Pipet-Plus
A mechanical pipette is one of the first tools that every technician learns to use and probably spends most of their day using. It is also one of the most ergonomic, which is important as repetitive tasks can lead to cumulative trauma disorders such as RSI (Repetitive Strain Injury). The Eppendorf Research plus microliter pipettes are intuitive to operate, provide a perfect balance and minimize operator strain and fatigue. Their light weight and low plunger forces reduce operating force during prolonged periods of time, making them ideal for long pipetting series.
The Research plus pipette line is equipped with a unique aspiration rate controller which allows different users in the lab to work at their own set speed, without having to alter the volume adjustment setting. This feature reduces the risk of errors and provides consistent accuracy across multiple technicians.
Designed as a system with thin-wall RAININ pipette tips, the Research plus single-channel and multichannel pipettes improve precision from sample to sample and between technicians. The spring-loaded tip cone and SoftEject features ensure low tip attachment and ejection forces. Additionally, the Research plus 16- and 24-channel pipettes enable efficient manual pipetting in 384-well plates with minimum operating force.
All models are characterized by a comfortable grip and a light operation. The rubber finger hook design on the handle supports a secure grip and reduces hand fatigue. The pipette’s ergonomics and stability are enhanced by a specially developed piston that is molded from high-performance polycarbonate. This material is dimensionally stable, resistant to chemicals and corrosion, and offers good mechanical properties. The piston’s surface is finely polished, which further enhances mechanical and optical properties, especially when working with solvents.
Using the adjustable aspiration control, different users in the lab can set their own aspiration speed and work with their preferred method of sample handling. This increases operational flexibility and reduces operator strain and error. Furthermore, a volume lock on the tip piston protects against accidental volume adjustment. The pipette’s volume display is clear and easy to read, even in dim lighting conditions. It is also a highly durable, chemical-resistant pipette with minimal maintenance requirements.
R-200 Pipet-Plus
The R-200 Pipet-Plus is a manual pipettor with a latch trigger mechanism and an aspiration rate controller that improve precision from sample to sample and technician to technician. Its design reduces thumb strokes by 50%, significantly decreasing the risk of cumulative trauma disorders. Combined with thin-wall RAININ tips, the pipette delivers lower spring and tip ejection forces, making it even more comfortable to use.
The patented piston latch locks the plunger at the zero point just before starting aspiration, and the aspiration rate controller ensures that users always completely aspirate. It also prevents them from accidentally changing the set volume during use. This feature eliminates the need for a separate, complicated adjustment procedure and makes it easier to maintain calibration.
Its small control wings make it easy to set the volume and lock it. The volume lock prevents accidental changes during regular usage, which could cause an inadvertent dispense. The R-200 is a highly reliable and accurate pipettor that offers a long service life with regular maintenance. This model is autoclavable, and its piston assembly is easily removable for cleaning.
This single-channel, variable-volume pipettor is ideal for both tubes and plates, and is compatible with all Socorex micropipette tips up to 1.0 mL. It is fully autoclavable and comes with a re-closable tipfillTM box that reduces storage space and waste volume. The re-closable box also helps to avoid cross-contamination, and it is available in both sterile and non-sterile options. The pipettor is backed by a 14-day inspection period from the time of shipment. Any defects found during this period are guaranteed to be corrected. Upon inspection, the instrument can be returned for a full refund, excluding shipping expenses. We recommend you speak to your local recycling specialist for information on how to dispose of the instrument safely. This is because liquid handling instruments may be contaminated with biohazards, chemicals and other hazardous materials. This could make it difficult to recycle or reuse.
R-300 Pipet-Plus
A mechanical pipette is one of the most common tools in a lab; it is typically used to transfer small amounts of liquid. It is important that the pipette is comfortable and easy to use so technicians can work for long periods of time without experiencing hand fatigue. The R-300 Pipet-Plus is a high quality mechanical pipette that is lightweight, durable and provides excellent comfort. It features an ergonomic design, universal autoclavability and an easy-to-read display. It is ideal for a variety of laboratory applications including dispensing, serial dilutions and mixing samples.
The R-300 is a single channel pipette that can be used to transfer volumes between 1 and 300 uL. Its compact and lightweight design makes it easy to hold in the hand for extended periods of time. It also has a finger hook design for added comfort. The R-300 is fully autoclavable and can be sterilized in a steam autoclave up to 121 degC for 20 minutes.
This pipette features a unique combination of novel and patented features for effortless accuracy. Its spring-loaded tip cone limits the attachment forces and guarantees a secure tip fit. This innovative feature helps reduce operating forces, which in turn decreases user-to-user reproducibility and the risk of RSI. Its light and ergonomic design makes it suitable for both multichannel and fixed volume applications.
Its advanced latch mode and aspiration rate controller ensure consistent and accurate sample dispensing. Its simple programming and positioned operation buttons make it easy to use. The R-300 has several modes for multiple and sequential pipetting, and serial dilutions. It can be easily switched between modes with the click of a button.
The Research plus single-channel and multichannel pipettes were designed in line with the Eppendorf PhysioCare Concept and feature low operating and aspiration forces, as well as a spring-loaded tip cone and SoftEject. The tip-forming groves on the Research plus pipette piston allow tips to stretch as far as their shape predefines, which further reduces the attachment and ejection forces. These features contribute to reduced operator strain and fatigue, making the pipettes safe for all-day laboratory use.
