Why the Stainless Steel Finish is Essential

Stainless steel sterilization baskets require a proper finish to increase the basket's versatility. The correct finish of stainless steel enhances it chemical resistance, handling characteristics and other key operational features. Let's take a look at the two most common finishes for stainless steel.

Sterilization Trays: Stainless Steel or Plastic?

Stainless steel and polymers are two of the most popular material options for sterilization trays used in the pharmaceutical and medical industries. In terms of toughness, long shelf life and resistance to contaminant absorption, surgical stainless steel outperforms plastic trays, especially for medical usage. Stainless steel trays also have a lower total cost over time.

VIDEO: How to Pull Glass using the PUL-1000 Micropipette Puller

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.

VIDEO: Getting Started with your PUL-1000 Micropipette Puller

The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here is a quick overview to get you started qui

VIDEO: Introduction to the Peri-Star Pro Peristaltic Pump

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.

How to Calibrate the Peri-Star Pro Peristaltic Pump

The Peri-Star Pro is a popular peristaltic pump. Here we see how to calibrate the pump so that the display shows the dispensed volume accurately.

In addition to the traditional RPM control, Peri-Star Pro also allows control of pump output by setting a calibrated flow rate. Flow rate is affected by tubing ID, tubing material, and rotor speed. Peri-Star Pro stores the flow rate relation of silicone tubing and rotor speed so that you can easily switch between controls for flow rate or RPM (revolutions per minute). Calibration is required for high precision pumping or after changing to a different type of tubing.

How to Load Capillary Glass in a PUL-1000 Micropipette Puller

The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here we will see how to load a piece of glass into the carriage.

Resolving Common Issues with the PUL-1000 Puller

The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here are the resolutions for some common issues with the puller.

VIDEO: How to Run a Glass Softening Test on the PUL-1000 Puller

The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. We will show you how to run a glass softening test.

VIDEO: Researcher's Review of the EVOM3

The EVOM is a special kind of voltmeter for measuring electrical properties across a layer of cells in culture or a biological membrane. It is the most commonly used commercial system for measuring across a layer of cultured cells. We are measuring TEER (TER) - Transepithelial Electrical Resistance. The EVOM3 allows us to zoom in and measure either resistance or voltage across these membranes or cells in culture.

The EVOM is a special kind of voltmeter for measuring electrical properties across a layer of cells in culture or a biological membrane. Here's a few things I like about the new EVOM3.

VIDEO: How to Install Tubing in Your Peri-Star Pro Peristaltic Pump

The Peri-Star Pro is a popular peristaltic pump. Here we will show you how to install the tubing in the pump head so that you can use the pump.

VIDEO: Researcher Compares EVOM3 with an Ussing Chamber

An Ussing Chamber is used when performing barrier studies across an excised epithelial tissue. Similar measurements can be made in well plates using an EVOM series TEER Measurement Meter, which is used for epithelial tissue that is grown to confluence in a cell culture well. While EVOM measurements are only qualitative, your throughput is much greater with an EVOM3. The EVOMs are portable and much more economical than an Ussing Chamber. Here Ben Dubansky, PhD explains the differences between EVOMs and Ussing chambers.

The Peri-Star Pro is a popular peristaltic pump. Here we will show how to set the system parameters for your application.

Get Familiar with Your New PUL-1000 Micropipette Puller

Let’s look at the PUL-1000, a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here we will examine the design of the unit.

How to Read a Vernier Scale

Vernier scales can be used on microscopesstereotaxic frames and micromanipulators. The vernier scale was invented by French mathematician Pierre Vernier in 1631 as an upgrade on Pedro Nunes' measurement system for precision astrolobes. With a main scale and a sliding secondary scale, a vernier is used for making precise measurements.
