PCR TUBES
The PCR tube is highly optimized to achieve excellent
PCR Supplies performance in various
thermal cyclers. These innovative and RNase-free PCR tubes are the results of years of
research on the best design of PCR tubes, coupled with meticulous craftsmanship to ensure
that each product is as perfect as the first product. The results speak for themselves,
and we are happy to introduce our ultimate PCR tube to the world. We will explore some of
the defining characteristics of these advanced thin-walled PCR tubes.
RNase-free PCR tubes with broad thermal cycler compatibility
Our RNase free PCR Tubes
are compatible with all the most common thermal cyclers on the market. We make sure to
optimize their design to ensure PCR performance that is agnostic to the thermal cycler.
This means that no matter which brand of thermal cycler you use, their performance is the
same.
The pipette is one of the most commonly used handheld instruments in a research
laboratory and the model of the pipette is chosen based on your needs for performance,
ergonomics and quality. But it doesn’t end there - you may have the most advanced
pipette on the market but a poor quality tip means that the reproducibility of your
results may be at risk.
Don’t be caught out; the fact is that quality Pipette Tips are critical to ensuring that the correct volume of liquid is
aspirated and dispensed and that your samples are not contaminated in the process. Here
are some quick hints to ensure that your pipette tips are a perfect match for your
pipette of choice and do not compromise your lab work.
The Reagent Bottle is a special
container for various liquids and solid reagents in the laboratory. The shape of the
reagent bottle is mainly divided into narrow mouth and wide mouth.
Since reagent bottles are only used for normal temperature storage reagents, they are
usually made of sodium calcium plain glass. In order to ensure a certain strength, the
bottle wall is generally thicker. Reagent bottle is divided into narrow mouth or wide
mouth, clear or amber,and with stopper or without stopper. Among them, glass stopper, no
matter small mouth, wide mouth, should have inside ground sand processing craft.
The specifications of HDPE Reagent Bottles are expressed in volume size, small to 30mL, 60mL,
ranging from thousands to tens of thousands of ml.
Precautions for use:
(1) when the reagent bottle is not used, you need to slip the paper between the
bottle stopper and the bottle mouth to prevent adhesion. As mentioned above, none of the
reagent bottles can be used for heating.
(2) according to holding the physical and chemical properties of the reagents needed
reagent bottles of the general principle is: dress up solid reagent selection jar,
holding liquid reagent - choose fine mouth bottle, all see light is easy to break down,
or metamorphic reagent to choose a brown bottle, holding low boiling point volatile
reagent chooses frosted PP
Reagent Bottles, holding an alkaline reagent selection with a rubber plug reagent
bottles, and so on. If the reagent has the above multiple physical and chemical indexes,
the appropriate reagent bottle can be selected according to the above principles.
(3) some special reagents, such as hydrofluoric acid, are not available in any glass
reagent bottles and are used in plastic bottles.
An Erlenmeyer flask is a widely used type of laboratory flask that features a conical
base with a cylindrical neck. They are usually marked on the side (graduated) to indicate
the approximate volume of their contents. It is named after the German chemist Emil
Erlenmeyer, who created it in 1861.
The conical flask is similar to the beaker, but is distinguished by its narrow neck.
The neck allows the flask to be stoppered using rubber bungs or cotton wool. The conical
shape allows the contents to be swirled or stirred during an experiment (as is required
in titration); the narrow neck keeps the contents from spilling. The smaller neck also
slows evaporative loss better than a beaker. The flat bottom of the conical flask makes
it unlikely to tip over, unlike the Florence flask.
Erlenmeyer flasks are used for pH titrations and in microbiology for the preparation
of microbial cultures. Plastic
Erlenmeyer Flasks used in cell culture are pre-sterilized and feature closures and
vented closures to enhance gas exchange during incubation and shaking.
If the flask is to be heated in an oil or water bath, a 'C' shaped lead or
iron weight may be placed over the outside to keep the flask firmly planted.
When heating, it is usually placed on a ring held to a ring stand by means of a ring
clamp. The ring keeps it over a Bunsen burner so that it is heated by the flame of the
burner. When set up this way, a wire gauze mesh or pad is placed between the ring and the
flask to prevent the flames from directly touching the glass. An alternative way to set
up the apparatus is to clamp the flask directly to the ring stand by means of holding it
with a test tube clamp around the neck of the flask.
