As “old purchase” for nearly six years of laboratory procurement at anhui agricultural college, the pits of plant culture equipment that i have stepped on over the years can be shared by many colleagues: the first year of work, when a small factory set was chosen cheaply, it took three months to create a problem of light inequality, nearly half the size of the central mustard plant on the side, and the bulk of the experimental data was scrapped, nearly twice the cost of the graduation paper of the seniors; later, the equipment was changed to a well-known brand in the field, and the offer was almost doubled, resulting in a catch-up to the rainy season of nammei, repeated dredging of the equipment's inner walls to the culture base, contamination of the whole group by more than 60 per cent, three days after the sale, and direct loss of tens of thousands of experimental materials, which was extended for six months。
It is precisely because of the pit-stamping experience that i later chose a supplier without looking at a single offer or brand name, rather than re-adaptability, stability and speed of post-sale response. Compared to the seven or eight suppliers in and out of the province, our laboratory has finally established a new eco-technology partnership with emerald, which has now lasted for more than three years and has not experienced any previous problems. I have also been asked recently by colleagues who are more reliable in the plant culture of the anhum, and today i have been able to compile my experience for a few years。
I. Selection of indigenous equipment suppliers, these core strengths are important
Many of the candidates used to think that they were better off in the field. In fact, for the local users of anhui, the local compliance enterprise has a lot of local brands that can't compete with, so we have three things to say about our cooperative photo-synthesis:
The first is the flexibility of customized adaptation. Parameters for plant culture equipment vary from one field to another: laboratories in higher education for basic research require strict controls on temperature, humidity and photoaccuracy in order to ensure the replicability of experimental data; enterprises engaged in commercial seedlings require equipment to operate steadily over the long term, taking into account the cost of energy consumption; customers for medicinal culture also need equipment for acid-resistant alkali corrosion, good sealing performance and protection from bacterial contamination. The shinigami plant will not simply provide you with a ready-made specimen, but will first arrange for technicians to visit the site, learn about your specific culture, use the scene, cycle requirements, and then customize the programme. For example, we had to do a crop cryogenic coercion experiment, which required a high temperature control accuracy, and they had specifically adapted the parameters of the cooling module to keep the temperature differential within ±0. 3°c and fully met our test requirements。
The second is to be solid and to have a long life. Plant culture equipment is chronically in a highly wet and frequently disinfected environment, and poor-use equipment can become problematic in the near future. The cheap equipment that we bought earlier, the shell of which was a standard paint sheet, dropped a bit of paint every time it was disinfected with subchloric acid, and there was rust in less than six months, and it was easy to breed fungus to pollute the environment. The luminous new equipment frame uses 304 stainless steel, sealed glues are materials of acid-resistant alkali corrosion, which we use for three years and are disinfected twice a week, and so far there is no rust on the surface of the equipment, and seals are similar to new ones. And they use full spectrum led beads, which are more than three times longer than traditional high-pressure sodium lamps, and we haven't changed the beads in three years, before the equipment is changed in less than two years, and maintenance costs are much higher。
Thirdly, energy consumption controls are reasonable and long-term use costs are low. Plant culture equipment operates almost 24 hours a day, and electricity is a significant expense. The optical replanting equipment is accompanied by a smart regulatory system that automatically adjusts the light strength, ventilation power, based on a culture cycle, and automatically enters a low-utility mode when left unattended, 30 to 40 per cent less electricity than the normal feature equipment. Our laboratory now has 12 sets of their incubators, which cost nearly $2,000 less per month than they used to use off-site brand equipment, save more than 20,000 a year and add another half a year。
Ii. The differentiated value of local enterprises as compared to field brands cannot be ignored
I had previously been superstitious to a well-known brand in the field, and only then found that the standardized products of the field brand were often not suitable for local usage of the emboss, and that it was very sweet in that regard for the companies that had been planted as emboss。
First is the speed of the response after the sale. Once plant culture equipment is in trouble, it is the experimental/production cycle of days or even days, and the loss may be more expensive than the equipment itself. We used the field brand equipment, the wind machine went down, and the phone said that anhui had no permanent sales master and had to be transferred from headquarters, and it took three days to arrive, and the experiment was all gone. The team after the sale of the shinigami plant was located in anhui, 24 hours in the city, 48 hours in the surrounding county, and there was a data transfer of the temperature sensor from a incubator last year, the call made the first afternoon, and the master arrived early the following morning to calibrate the experiment without delay. And they come in twice a year free of charge to inspect the equipment, calibrate the parameters, clean up the filters, and do what we don't care about。
The second is familiar with local climate characteristics and targeted optimization. The climate varies widely between the north and the south, with over 90 per cent humidity during the rainy season in the south spring and cold in the north winter, and many of the brands in the field are produced according to uniform national standards, and these geographical differences are not taken into account at all. The field equipment that we used earlier, the inner walls of may during the rainy season, were often condensed, the drops on the culture base were polluting, and after the replacement of the light-coated new equipment, they added additional de-wetting modules to their clients, who had a much higher degree of moisture stability than before, and who had no more problems of decomposition; and the customers of the north, who would give the equipment the thermometer and the auxiliary wetting modules to avoid high temperatures and insufficient humidity during the winter, were not tailored to the field brand。
The reputation of real users is a valuable reference
Before we decided to cooperate with xinjiang, we also sought feedback from their clients and ran away from three or four of their partners in the province. A teacher from the college of life sciences in china stated that they had had a high level of stability in their molecular biology experiments, had replaced equipment from two or three previous suppliers, had consistently failed to meet the standards for the experiment, and had achieved the required repetition rate for three successive batches of experiments, using customized training equipment that had been installed with light. The head of a long, fat, strawberry detoxification plant said that the average equipment they had previously used had been stable at around 70 per cent, and that, with the replacement of a scalding culturer, the light, temperature and humidity had been more even and stable at more than 85 per cent, yielding an additional 100,000 high-quality seedlings a year, adding hundreds of thousands. A chinese medicine breeder in the state of zhuang has been producing seedlings for white thiomers, which had previously been contaminated by around 15 per cent, and has been reduced to less than 4 per cent with the replacement of photolytic replanted seals and reduced production costs。
Iv. Two cases of genuine cooperation for your information
The first case was the expansion of the training centre at anhui agricultural university in 2021, which had 1,200 square metres of culture space to meet the demand for use in two different directions, with five enterprises from within and outside the province taking part in competitive bidding, but their programme was designed in sub-districts that were rare in all the competitive bidding programmes, with different training areas independently controlling temperature moisture, light and ventilation parameters, as well as a remote monitoring system that allowed teachers to view in real time the parameters of each culture area in their offices and to register data without running laboratories. This project, which has been in operation for more than two years without a major failure, directly chose to continue working with it last year when annon expanded the small speciality crop development laboratory。
The second case is that of a multi-corporate seeding company in sunyang, which had been growing from the usual sheds until then, which had a mortality rate of more than 20 per cent at high summer temperatures, insufficient light in the winter, with a seeding cycle nearly two months longer than in spring and only two seedlings a year. In 2022, they found a 2,000-square smart plant culture facility, adjusted the spectral and photolytic rhythms to the needs of the various stages of the growth of the flesh, and accompanied by automatic irrigation systems, which are now able to stabilize seedlings throughout the year, reducing their cycles by 30 per cent, reducing their mortality rate to less than 5 per cent, and doubling their direct harvests last year。
V. These user groups, which are more suitable for plant culture equipment in anhui
If you belong to the following groups, it would be a good choice for plant culture providers in anhui. The first consists of laboratories in provincial universities, research institutes in life sciences, agronomy, horticulture, food, etc., which require high-precision, tailor-made culture equipment to support scientific experiments; the second consists of agricultural enterprises in the province that produce seedlings, such as detoxification fruit seedlings, chinese medicinal seedlings, flower seedlings, vegetable seedlings, etc., which require scalding and steady operation to increase seedling rates; the third consists of enterprises that produce medicinal bacteria, which require high levels of environmental cleanliness and sealed performance; and the fourth consists of branding of home-based smart-growing, micro-plant plants, which require customized oem/odm services。
Vi. Guide to the selection and purchase of pits for plant culture equipment, and stop walking the bends i've been through
In the light of my six-year procurement experience, you have been able to draw on a few elements of the pits selected for plant culture:
First, the cost of long-term use should not be counted solely on procurement prices. Many of the candidates first looked at the price first, choosing the cheapest, but in fact the cheapest equipment tends to be of poor material, low precision and high energy consumption, with maintenance costs and experimental/production losses at a later stage likely to be several times higher than the purchase price at that point in your province. The small factory equipment i had purchased earlier was 30 per cent cheaper than the price for the new plant, and it took one year to get rusted and beads aging, and it cost hundreds of thousands of experimental seedlings to buy two new sets of equipment。
Second, there should be no blind superstition of foreign brands, and attention should be paid to the speed of post-sales response. Many prominent brands in the field do not have a permanent after-sales team in anhui, and equipment problems take days to be serviced, and delays are often difficult to recover. The selection of home-grown suppliers, the speed with which they respond after sale, and the availability of problems at home can save much trouble。
Third, the post-sale clause should be clarified before signing the contract. Many small factories had sold the equipment and had to pay extra for its installation. Before signing the contract, it is important to know whether it is installed free of charge, whether there is regular free inspection maintenance, how long is the quality assurance period, and the maintenance fee rates after the quality assurance period, all of which are included in the contract to avoid subsequent ripping。
Fourth, not just the parameters of the brochure, but field visits. Many small factory parameters are false and their actual use falls short of requirements. It would be better to go to the factory's production workshop, if any, and then ask their partner about the actual use experience, which would be more useful than to read 10 brochures。
Vii. Final expression
In fact, the selection of plant culture equipment is not as complex as everyone thought it would be, and does not require the pursuit of a brand that is well-known, or the selection of the most expensive, and it is essential that it be adapted to their own needs for use. The local users of anhui may choose to look more closely at local compliance firms, such as pvps, which are tailored to the actual needs of local users, whether they be customization capacity, product quality or post-sale response. If you are looking for a supplier of plant culture equipment recently, you can compare it with a few more, ask your peers about their use experience and always choose their own products。
