Cole-Parmer® Watson-Marlow Variable-Speed Peristaltic Pump System

The Watson-Marlow Variable-Speed Pump System is a compact, benchtop peristaltic pump designed to deliver exceptional accuracy, repeatability, and ease of use for laboratory and industrial fluid handling applications. Its space-saving design, intuitive digital controls, and maintenance-free motor make it ideal for precise dosing, transfer, and metering of a wide range of fluids.

This peristaltic pump operates from 1 to 200 rpm in precise 1 rpm increments, providing flow rates from 0.001 to 120 mL/min or 0.002 to 190 mL/min, depending on tubing size and pump head configuration. The MAX key enables rapid priming, while forward/reverse controls simplify fluid transfer tasks.

Peristaltic pumps maintain fluid integrity by ensuring that only the tubing bore contacts the fluid, eliminating cross-contamination risks. This pump is suitable for:

• Viscous fluids
• Shear-sensitive fluids
• Corrosive or abrasive liquids

• When used with VACUBOY hand operator and attachments, offers unparalleled speed and flexibility when aspirating from any type of vessel from flasks to 96-well plates

The VACUSAFE comfort is a self-contained, multifunctional vacuum aspiration system that offers many benefits over "homemade" systems connected directly to a lab vacuum line or faucet. When used in conjunction with the VACUBOY hand operator, the VACUSAFE comfort provides unparalleled performance, flexibility, and safety when aspirating media, biological fluids, or chemical solutions.

VACUBOY Benefits and Features:

• Time-savings and flexibility particularly when aspirating from multi-well plates
• Dual vacuum speed control either with push button on top, or rear turn setting
• Single, 4-channel, and 8-channel adapters available
• Adapters include disposable pipette tips, Pasteur and serological pipettes, or fixed stainless steel pins

The VACUBOY hand operator is designed to accommodate a variety of aspiration adapters including stainless steel pins, disposable tips, and Pasteur or serological pipettes. Each adapter is designed to perfectly match the physical dimensions of typical laboratory vessels including flasks, bottles, and multi-well plates. It can be used in conjunction with the VACUSAFE aspiration system or a stand-alone upgrade to your current system.

VACUBOY Attachment Options:

• Single stainless steel aspirator (40mm, 150mm, or 280mm)
• 4-channel stainless steel aspirator
• 8-channel stainless steel aspirator
• Single-channel adapter for pipette tip, (w/ or w/o ejector)
• 8-channel adapter for pipette tips, with ejector
• Rubber adapter for Pasteur and serological pipettes

Our quiet, reliable, and low cost two-stage high vacuum rotary vane pump comes both in 120V and 220V versions with or without a gauge.

Aspire Aspirator

• Compact Design
• Built-in Vacuum Pump
• Adjustable Vacuum Pressure
• Vacuum Gauge
• Safe and Precise Aspiration

The Accuris ASPIRE Laboratory Aspirator incorporates a quiet, maintenance-free pump inside a sturdy, yet compact base. The vacuum is fully adjustable, with a pressure gauge that displays the vacuum level, allowing full control of aspirating speed. The ASPIRE is an ideal choice for a wide range of laboratory aspirating applications, including removal of media from tissue culture vessels or plates, and supernatants. An ergonomic, hand held aspirating device is included, and holds standard 200 to 300ul disposable pipette tips.

Comes complete with:

• Base with internal vacuum pump
• 2 Liter, Polycarbonate Collection Bottle (autoclavable and break resistant)
• Antibacterial / Hydrophobic Filter
• Silicone Tubing
• Handheld Vacuum Controller
• 2 Pipette cone adapters (for 200 ul pipette tips and 40mm stainless steel)

The collection bottle incorporates a reliable Overflow Protection Valve that closes off the tube to the vacuum in the event of a full bottle. In addition, the replaceable in-line filter protects the vacuum pump from contaminants and any moisture that comes through the bottle. Graduations on the collection bottle indicate the amount of fluid collected and when it's ready to be emptied. The Handheld Vacuum Pipette has an ergonomic design that's comfortable in the hand during prolonged use.  Pressing the button applies the vacuum. The pipette accepts Pasteur pipettes, serological pipettes, and also comes with 2 accessory pipette cones. One cone is designed to accommodate 200/300ul pipette tips, the other has a thin, stainless steel capillary for fine control aspirating.
