Syringe filters are necessary for the fast and efficient handling and filtering of liquids in labs and research facilities. We offer disposable syringe filters in 13mm, 25mm, and 33mm sizes. All our filters are composed of membranes reinforced with polypropylene houses. They give a reliable seal without requiring adhesives. We offer a choice between sterile and non-sterile filters for pre-filtration, clarification, and fine particulate removal.

NextDayScience serves industrial, government, pharmaceutical, educational, and life science industries. The company provides laboratory consumables, research equipment, digital imaging, and microscopy products to customers around the world.

Strategic alliances with manufacturing companies allow NextDayScience to provide streamlined and cost-effective solutions for their clients. Four types of laboratory supplies the company carries include:

Tissue culture is a generic term for organs and cell cultures. The termis used interchangeably. Cell cultures come from cell suspension and primary tissue explants. Primary cell cultures have a finite life span.

Tissue culture is a technique or process of making tissue grow in a culture medium that is outside the organism. When direct access to cells is needed, culture dishes are the choice formats. The cell culture dishes used in the process must be sterile.

The serological pipette is a laboratory instrument that transfers liquids measured in volume by ml. Most have graduations on the side for measuring the liquid being dispensed or aspirated. An important step when culturing or plating cells is the even distribution throughout a solution.

The use of serological pipettes is an efficient and gentle means of mixing cell suspensions. They can also be used for mixing reagents and chemical solutions. After treatment or isolation of experimental cell cultures, serological pipettes are useful in transferring colonies of cells for further empirical analysis or expansion.

Following scientific and medical advances, the first ultra-low freezer was developed in 1991. Temperatures could reach -152° C. The advances included in vitro fertilization and stem cell transplants. Since then, cryogenic freezers have a bigger capacity, alarm system, better refrigeration technology, and improved insulation.

Twenty years of specialist expertise is responsible for ultra-low temperature freezers that offer unparalleled uniform temperatures, reliability, and safety. 

A clean room is a controlled environment having low levels of pollutants like chemical vapours, aerosol particles, and airborne microbes. The 100,000 indicates the number of particles per cubic meter. Typical city environment air contains 35,000,000 particles per cubic meter.

Many scientists are on the fence about cryogenics. Most have not investigated enough to have a scientific opinion. Cloning was once a process thought to be impossible. As the basis for cryonics progresses, more cryobiologists are acknowledging the scientific feasibility.

Sixty eminent scientists have affirmed cryogenics as a science-based endeavour. Science-based does not have the same meaning as current science. Cryogenics is a protoscience that is based on the expectations of repairs and vitrification of capabilities of science in the future.

It would take a book to list all of the laboratory supplies that NewDayScience has to offer. There are four types of laboratories. They are physics, chemistry, biology, and home science labs. NewDayScience has supplies for each of them.

Science Lab Equipment

Lab goggles protect the eyes from chemical splashes and flying objects. A triple beam balance is found in most science laboratories. It is a device used to measure any object's or substance's mass. Test tubes are small glass containers used to heat small amounts of materials or view chemical reactions.

Beakers are wide-mouthed containers used to store, heat, or transport substances. Flasks are narrow-mouthed containers that are used to store, heat, or transport substances. They are usually used when stoppers are required.

Storing samples at low temperatures is necessary to extend the viability of reserved samples. Storing samples in mechanical freezers at -80°C slows down metabolic activity but does not stop it. Sample temperatures must be below -132°C to halt metabolic activity.

Storing below this temperature assures safe preservation. The approved range for storage equipment is -80° C to +100° C. In practice, cryogenic equipment is used until temperatures reach the vapour phase temperature of nitrogen which is between -150° C to -196° C. The location and distance from the vessel of liquid nitrogen have an impact on the vapour causing temperature.

Medical specimens are delicate and require the proper care in order to be useful for determining the state of a person’s health and wellness. A modern medical laboratory functions under strict guidelines for sterilization of the environment, as well as the specimens coming into the lab for testing. In order to maintain these strict guidelines, medical laboratories need several pieces of essential equipment to house the specimens as they enter the care of the laboratories. Two of these pieces of equipment are incubators and general purpose baths. Let’s look at this equipment to understand their function, the different types of equipment, and why laboratories need them as part of their essential lab equipment line up.

Pipette Controllers allow you to quickly fill and release accurate volumes. They attach to a pipette, which can be glass or plastic, that’s holding the liquid or volume itself. The controller’s job is to be sure you’re dispensing the correct amounts of liquid at the right times, whether you’re doing research in a lab or in a medical setting. This kind of precision is crucial to getting the exact measurements of chemicals and other liquids.

Before nitrile examination gloves were invented, doctors and nurses had no protective covering for their hands. Disposable gloves started with one man’s vision to help his wife prevent rashes from developing on her hands when they were in surgery. In 1889, Dr. William Steward Halstead noticed that his nurse, and later wife, Caroline Hampton, developed rashes from the chemicals she handled. In need of a solution, Halstead reached out to the Goodyear Rubber Co. who created rubber gloves for her hands. This was such a success that eventually his entire surgical staff wore gloves during operations.

Machines that remove heat from a liquid through a vapor-compression or absorption refrigeration cycle are called chillers. The refrigeration cycle chiller creates waste heat that, when removed, results in greater efficiency. To accomplish this, liquid can be circulated through a heat exchanger, thus cooling the equipment. When it comes to vapor-compression chillers, they require compressors which are mechanical devices that can be powered by electric motors, steam, or gas turbines. These chillers utilize four basic types of compression: reciprocating compression, scroll compression, screw-driven compression, and centrifugal compression. Evaporative cooling heat rejection allows their coefficients-of-performance to be very high.

Before we discuss digital microscope cameras, let’s briefly review what distinguishes digital microscopes from other types of microscopes. A digital microscope is a variation of a traditional optical microscope that uses optics and a digital camera to output an image to a monitor via computer software. They usually have their own built-in LED light source, and since the image is focused on the digital circuit, the entire system is designed for the monitor image. There is no provision to observe the sample directly through an eyepiece, as you would find on an optical microscope, and therefore the optics for the human eye are omitted. Digital microscopes are commonly low priced commercial microscopes designed to be used with a computer.

Graduated Cylinders and Beakers are both common pieces of laboratory equipment. A Graduated Cylinder has a narrow cylindrical shape with each marked line showing the volume of liquid being measured. While they are generally more accurate and precise than laboratory flasks and beakers, they should not be used to perform volumetric analysis. They are also sometimes used to measure the volume of a solid indirectly by measuring the displacement of a liquid. Whatever your use may be, these varieties can handle the task.
