Suitable laboratory instruments are an important means to ensure the accuracy and efficiency of experimental results. So what kind of instruments are suitable for the laboratory? Lebe wants to be a laboratory buyer, a well-funded laboratory, and a limited- edition laboratory. But one thing in common is that you want to purchase the right laboratory equipment. Some purchasers use imported and domestic products as the standard for distinguishing between good and bad instruments, which is an inaccurate positioning for laboratory procurement.
Ika laboratory instrument
Here, Lebee will share and discuss how to choose laboratory instruments at three points. What should I pay attention to when choosing a laboratory instrument ? .
First, expensive and good instruments
There may be sufficient labor in the laboratory, so "money is not a problem, expensive to buy"; and some laboratories have limited funds, so "no money, pick a cheap buy." Both of these situations are not advisable. Expensive is not necessarily suitable, only a suitable laboratory instrument is a good instrument. Your instrument is enriched in the laboratory, but if it is not applicable, it will only greatly reduce the efficiency of the experiment, and the funds invested will only become a useless vase. On the other hand, if the instruments purchased due to limited funds are instruments that are inexpensive but not guaranteed in quality, the experimental efficiency will also be reduced. Therefore, the price level does not necessarily match the quality of the instrument. We must first consider the quality at the price when comparing the instrument.
Second, brand and user word of mouth
Some people may say that the price of big brands is often high, and consumption is not affordable, but it is undeniable that the quality of big brands is certified by the majority of users. The reason why a brand can be called a brand is determined by the user, not by its price. That is to say, if a brand can be called a well-known brand in the industry, the user's reputation and quality of the brand's products are definitely very good. Therefore, when choosing a laboratory instrument , we can also choose brands with good user reputation (such as IKA , Mettler , Eppendorf, etc.), and then compare technical parameters, prices, etc. under actual requirements.
Third, the requirements for instrument selection
As a user who uses the instrument, some users do not know the instrument better than the supplier. In this case, firstly, they should communicate and understand with the supplier to obtain the performance and indicators of the general instrument. Of course, due to the unevenness of supplier capabilities and integrity, it is difficult to judge the purchase of laboratory equipment by users. So how do you do it?
1 Pay more attention to some parameters that are obviously higher than the general indicators in the industry. It is best to clarify the inherent technical support of these indicators. If there is no technical support inherent in the instrument, then this instrument with significantly higher than the general indicators in the industry is still less. It is good to touch.
2 Focus on the main indicators of the instrument, do not be confused by some additional features and ignore the attention to the main indicators.
3 Pay more attention to those verifiable indicators, so that some bad suppliers will find it difficult to retreat.
4 Pay attention to the external and internal environment used by laboratory instruments : temperature, power consumption, reagents, catalysts, water, etc., to investigate the environmental adaptability of the materials used in the instrument.
5 For those who put the word "most" on their mouths but can't prove it, they should avoid it.
6 Try to avoid the cheapest instruments, and if cheaper instruments don't bring efficiency, then it's still the most expensive.
The above is some experience of the procurement of instruments by Lebe (Shanghai) Scientific Instrument Co., Ltd. , I hope to be helpful to everyone.
