HERMLE Z287-A Microcentrifuge PLUS

• Multipurpose, 11 available rotor options
• Up to 14,000 rpm and 16,058 x g
• Swing out rotor options for tubes and plates
• Indicator Light, easily view cycle status
• Unique EZ-Scroll™ touchpad
• 5 Year Warranty 

The Z287-A exceeds the limitations set forth by traditional microcentrifuges which are restricted solely to fixed-angle rotors for microtubes. Instead, this compact, next-generation model features an expansive line of swing-out and fixed-angle rotors options that accept microplates and test tubes up to 50 mL. We have designed this centrifuge to be our most compact and economical. A true workhorse for any lab requiring a centrifuge that can accommodate many fields of research.

Along with a broad range of available rotor options, the Z287-A introduces a convenient status indicator. Users can easily view the current state of the centrifuge from across the room. The LED illuminates to signify if the rotor is spinning, the run is completed, or the centrifuge is idle in standby mode.

Advanced microprocessor controls allow for instant rotor identification, which automatically converts the rotational speed to the relevant g-force (rcf), preventing the user from setting a speed above the capabilities of the installed rotor. In addition to retrieving saved programs, the EZ-Scroll touch wheel front panel can adjust acceleration/deceleration rates and change the end-of-run alarm tone. Additionally, this feature prevents debris buildup, leakage, and can be operated with gloves on. The Z287-A is a truly powerful and versatile centrifuge perfect for any research laboratory.

Excel™ Single- and Multi-channel Electronic Pipettors

• Exceptional Accuracy and Precision
• Simple, Precise Vol Setting
• Fully Motorized Piston Drive
• Multifunctional with Six Operational Modes
• Virtually Eliminates Pipetting Force
• 1-year warranty 

Excel™ Electronic Pipettes are multifunctional units with operational modes for standard and reverse pipetting as well as multiple and sequential pipetting, mixing of samples, and serial dilutions. All functions are easily programmed with one hand on the well-positioned display and keypad. A fully motorized piston drive and auto-calibration guarantee excellent accuracy and reproducibility. A removable, rechargeable lithium-ion battery ensures many hours of performance between charges.

The body of the pipette has been designed to fit comfortably in the right or left hand. Along with being lightweight, the unit is also well-balanced. The plunger button, located on the back side of the instrument, requires just a small movement of the index finger to activate, reducing the risk of Repetitive Strain Injuries (RSI). The tip ejector slides easily with slight pressure from the thumb.

A small, rechargeable, lithium-ion battery powers the Excel™. A complete charge is achieved in just eight hours and last for 2,000 pipetting cycles. To ensure that a fresh battery is always available, a stand-alone charger and extra batteries are available. Also available is a 3-position linear stand for up to three single or multichannel pipettes and a carousel stand for up to six single or multichannel pipettes.

• Simple: Precise control for accurate volume setting and delicate cell culture work
• Easy: Integrated rest position
• Efficient: Service-friendly and sustainable 

The accu-jet® S pipette controller brings versatility and endurance to your team. It makes lab work simple, easy, and efficient, whether you work with cell cultures, in quality control or in a pharma lab.

Precise pipetting of large and small volumes is easy due to single-handed control of pipetting speed for fast, powerful aspiration, accurate meniscus setting, or precise dispensing of small volumes. The precise control ensures you always achieve the required volume spot-on when working with graduated or bulb pipettes. If you need extra power or precision, motor speed is controlled on the fly with one hand, choose between gravity-delivery (for pipettes calibrated "to deliver") or powered blow-out delivery (for pipettes calibrated “to contain”).

Convenient functions support efficient work with minimum interruptions. You can typically work for 8 hours of continuous pipetting without recharging*, and the accu-jet® S can be used while charging. Even during short breaks, the accu-jet® S saves time. With the integrated rest position, you can place the instrument on the benchtop on its back with an inserted pipette. The instrument remains ready to use and accessible for you to continue your work at your convenience.

Efficient use of resources is what the accu-jet® S is all about. It is designed to make routine service tasks such as membrane filter replacement, adapter change, or battery replacement simple and easy for you. This and the robust design make it the perfect choice for long reliable service. The valve system ensures that no vapors remain inside the instrument, thus preventing corrosion. The membrane filter and check valve prevent liquid from accidentally getting into the instrument.

Dispensette® S Trace Analysis Bottle Top Dispensers

• Simple to mount discharge tube available with or without integrated recirculation valve
• Designed without additional sealing rings for ease of cleaning and maintenance
• Replaceable discharge valve with safety valve
• Olive-shaped filling valve for firmer attachment of filling tubes
• Improved flow technology results in faster priming

The Dispensette® S Trace Analysis is the next generation bottletop dispenser for precise volume dispensing of high-purity media for trace analysis. It is especially suited for dispensing acids, bases and hydrogen peroxide in the volume range from 1 to 10 mL. The components of the fluid path have been selected to only contain the highest purity materials, such as fluoroplastics and sapphire. The result is a trace metal content of dispensed liquid generally in the low ppb range, or even in the low ppt range, depending on the application. Both platinum-iridium and tantalum valve springs are available for application compatibility.

Dispensette® S Organic Analog Bottle Top Dispensers

• The GL45 mm standard thread, plus included adapters, fit most common lab bottles
• The valve block rotates 360° so the bottle label always faces the user for safety
• Telescoping filling tube adjusts to different bottle sizes
• Easy to disassemble for cleaning
• Simple to mount discharge tube available with or without integrated recirculation valve
• Designed without additional sealing rings for ease of cleaning and maintenance
• Replaceable discharge valve with safety valve
• Olive-shaped filling valve for firmer attachment of filling tubes
• Scalloped track for secure volume setting on analog dispensers

Dispensette® S bottletop dispensers build on the 50 year history of BRAND® dispensing expertise. Continual upgrades makes this the safest and most convenient ever, while retaining the features making the Dispensette® the world's favorite bottletop dispenser. The "floating piston" design of the Dispensette® S forms a zero-wear sealing system with outstanding sliding properties. Optimized flow channels make dispensing and priming even easier - particularly in instruments with large volumes.

The Dispensette® S Organic has much in common with a Dispensette® S, however there are two major differences. The Dispensette® S Organic has a glass piston, rather than a PFA-coated piston. This optimizes it for use with concentrated acids and organic solvents that can interact with the PFA, but makes it less useful for bases. In addition, the valve spring in the Dispensette® S Organic is tantalum (vs. platinum-iridium alloy) allowing it to be used with peroxides, again, at the expense of compatibility with bases. Because of the different construction and chemical compatibility, parts from a Dispensette® S should not be used with a Dispensette® S Organic, and vice versa.

The Dispensette® S Organic bottletop dispenser is supplied with: discharge tube, valve mounting/calibration tool, polypropylene adapters, telescoping filling tube, recirculation tube (optional), performance certificate, operating manual, and one year warranty.
