Below are some popular pullers from WPI, including Sutter pullers. Here we compare them so you can choose a system that is best suited for your application.

Cleaning laboratory syringes helps prevent contamination and ensures accurate dosing. You should always adhere to the protocols of your institution and the manufacturer of your syringe. Specific cleaning requirements may vary based on the intended use of the syringe, its material composition , and the sample fluid introduced. Here is a typical protocol for cleaning a laboratory syringe.

Laboratory syringes are used for accurate measurement and administration of fluids in medical, laboratory, and industrial settings. Proper maintenance is crucial to ensure their functionality and accuracy. Here we will examine some common maintenance issues you may encounter with your reusable laboratory syringes.

Laboratory forceps are surgical instruments that come in a variety of types. Here’s a brief overview to help you choose a set of forceps for your application. Surgical forceps can be divided into two broad categories, thumb forceps (also called tweezers) and hemostatic forceps. Tweezers can be further divided into dressing forceps and tissue forceps.

Choosing the right syringe type depends on the specific application and the requirements of your task. Syringes come in various sizes, materials, and designs, each suited for different purposes. Here are some factors to consider when selecting a syringe type.

WPI carries a wide variety of fluid handling tools utilizing different technologies:

• Microinjectors
• Peristaltic pumps
• Syringe pumps
• Pneumatic injectors

The range of applications and the criteria used to select a particular pump or injector is broad and complex, and we encourage you to call us at (866) 606-1974 or email customerservice@wpiinc.com and speak with an application specialist. In the meantime, here is a listing of our popular pumps and injectors sorted by technology, flow range and special features.

Special features tell you about applications or functionsof the pump. Many of the syringe pumps can be had with an alarm option that alerts you to the end of travel or blocked flow. The onew with the “P” option allow for programmable flow and volume profiles without using the RS232 computer interface.

Frequently used terms:

• Infuse/Withdraw (I/W): Describes a feature of a syringe pump whereby the syringe plunger is held by the pusher so the motor can pull the plunger back, withdrawing...more

The manual microsyringe pump is a convenient tool for precise manual injection of fluid using glass pipettes or similar injection devices. The design allows visual feedback of flow at the pipette tip. They can also be used as a manual micro syringe pump for perfusion or withdrawal of liquids. The resolution of the injection volume can be continuously varied from 10 nanoliters to the microliter range, depending on the syringe used. Here we show you how to setup your system.

1. Loosen the set screw on the  Adjustable Micrometer Mount, but do not remove it.
2. Tighten the thumb screw on the Ajdustable Micrometer Mount.
3. Insert the digital micrometer or the manual micrometer through the hole on the Adjustable Micrometer Mount. Then, tighen the set screw.
4. Loosen the set screw on the Syringe Piston Mount Bracket.
5. Install the Bracket on the Spindle of the Micrometer. Tighten the set screw on the Bracket
6.  Loosen the Syringe Piston Mount Bracket thumb screw and the Syringe Mount Bracket thumb...more

WPI offers alkaline cleaners for the pharmaceutical, biotech, medical device, healthcare, precision engineering, and other sectors.

The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here is how to run a program that will pull two identical microelectrodes.

Loading a Program

We will use the keypad to navigate through the display.

1. Use the arrows to navigate to LOAD (00). The top and bottom arrows on the keypad navigate numbers in increments of 1. The left and right arrows on the keypad navigate numbers in increments of 10. Press ENTER. The number will start blinking.
2. Use the arrows to navigate to the program number you would like load. Once you reach the desired program, press ENTER to run the program and pull your glass.

Creating a New Program

1. Use the arrows to navigate to STEP 1 - HEAT. Press ENTER. The number will start blinking.
2. Use the arrows to set the desired value for the heat. Press ENTER.
3. Navigate to STEP 1 – FORCE. Press ENTER. The number will start blinking.
4. Use the arrows to set the desired value of force. Press ENTER.
5. Navigate...more

Let’s look at a Peri-Star Pro peristaltic pump, which is available in four models for high and low flow rate, and 2, 4 and 8 channels. Here’s a quick introduction to the pump.

Control Keypad

Setup and operation are controlled with a Control Knob and three membrane keys. Pressing a membrane key once activates the key function.

• The Run/Stop button switches the pump on or off. If the pump is running, pressing this key immediately stops pump. If the pump is off, pressing the key turns it on.
• The Rotation Direction button sets the rotor direction clockwise or counterclockwise. The direction is shown on LCD display.
• The Full Speed button runs the pump at maximum flow rate. This is convenient to use when evacuating or cleaning the system.

Control Knob

The Control Knob provides two functions by rotating or pressing. Rotate the knob clockwise to increase the pump’s flow rate or counterclockwise to decrease the pump’s flow rate. Slow rotation makes a small change in the flow rate. Fast rotation...more
