Masterflex L/S Easy-Load II pump head

This upgraded version of the Easy Load pump head retains tubing safely in place with no manual adjustment. With its compact design and 4 rollers, it offers optimal use of space and low pulsatility.

  • Designed for different sizes of tubing, from 0.001 to 2900 mL/min
  • Compact for space-saving purposes
  • Adjustable occlusion or open-head sensor option
  • Stackable up to 4 pump heads (on compatible drives)
  • Fixed occlusion (adjustable occlusion option available)
  • Open-head sensor option

Compatible with Masterflex tubing:

  • Standard: L/S 13, L/S 14, L/S 16, L/S 25, L/S 17, L/S 18
  • High-performance: L/S 15, L/S 24, L/S 35, L/S 36

Materials

The pump head housing is made of polyphenylene sulfide (PPS) for protection against corrosive liquids and vapors. The rotor is available in two materials:

  • plated cold-rolled steel (CRS) for general applications
  • 300 stainless steel (SS) to resist more corrosive fluids

Options

The open-head sensor option automatically stops the motor when the pump head is opened to increase safety while working with the pump, provided that the drive is sensor-equipped.

The adjustable occlusion allows better control over the flow system. An increased occlusion maximizes pressure performance and a better suction lift, while a reduced occlusion extends tubing life.

Darwin Microfluidics being based in France, ships orders under Delivered At Place (DAP) incoterms. This means that for customers outside the European Union (EU), you are responsible for any applicable customs fees, duties, and taxes in addition to the shipping costs. These charges are determined by your local customs authority and must be paid by you upon the arrival of the shipment in your country.

We recommend contacting your local customs office for detailed information on these charges if you're ordering from outside the EU, as they can vary depending on the destination and the value of your order. Please note that these additional costs are not included in the shipping fees charged by Darwin Microfluidics.

Competitive list prices: We work hard to ensure our list prices are among the most competitive in the market. This approach allows us to offer fair pricing to all our customers from the start, eliminating the need for frequent discounts.

Since Darwin Microfluidics sells exclusively to companies and institutions and is based in France, the VAT treatment for your orders depends on the location of your company or institution:

Within the EU (excluding France): For customers in other EU countries, the reverse charge mechanism applies. This means that VAT is not charged by us at the point of sale. Instead, it is your responsibility to account for the VAT at the standard rate applicable in your country under the reverse charge procedure. This process helps simplify cross-border transactions within the EU.

In France: For customers located in France, standard French VAT rates apply to all purchases. As a France-based company, we are required to charge VAT on sales to other French companies and institutions, which you can then reclaim according to local VAT procedures if applicable.

Outside the EU: For customers outside the European Union, sales are not subject to VAT by us. However, you may be subject to import duties, taxes, and charges that are not included in the item price or shipping cost. These charges are the buyer's responsibility and vary by country. We advise checking with your local customs office for more information.

Please ensure your VAT identification number is provided during the ordering process for EU transactions to qualify for the reverse charge mechanism. If you have any questions regarding VAT charges or need further assistance with VAT-related issues, please contact our customer service team.

We are unable to provide specific estimates for customs fees, duties, or taxes associated with your order. These charges are determined by the customs authority in your country and can vary based on a variety of factors, including the type of items purchased, their value, and the country to which they are being shipped.

We recommend contacting your local customs office directly to get the most accurate and up-to-date information regarding potential customs charges for your order. They can provide you with detailed guidelines on the fees you might expect to pay based on the products you're importing from us.

Please remember, these charges are the responsibility of the recipient and are not included in the shipping costs paid to Darwin Microfluidics.
