Mysterious chinese glassware sellers

Chemiston - 29-5-2016 at 02:32

First of all, I wish no one bust me all over saying there is similar posts, cuz i have scooped the threads but still not satisfied with the result, so i decided to start a new topic.

So i have been looking for glassware in ebay and amazon and found that original ones like pyrex are expensively price tagged, where on the other side you find numerous chinese glassware sellers getting their price at a normal level (cheap:D) so i thought maybe they sell loads of crap with pictures of glassware, specially that there products are seldom rated and never reviewed to an extent, so before going shopping those glassware i decided to ask you about any personal experience , specially these stores : nanshin sales, sam10086,deschem ,reacware and laboy

Also one product i find interesting
http://www.amazon.com/NANSHIN-Glassware-Advanced-Chemistry-g...

For a fellow amateur chemist

Didja even bother to look at user feedback on eBay? And you have NOT UTFSE here either. I have had personal (very positive) experience with both sam100086 and deschem, and posted HERE about it.:(

highpower48 - 29-5-2016 at 09:54

Reacware and descent has been talked about on here. Both are reliable sellers of glassware. I have used both and never had an issue.

Chemiston - 29-5-2016 at 12:16

My main point here is nanshin sales , any idea pleeese ,thx

Start with a low-value item to limit the Risk if you canot afford to lose.

arkoma's suggestion of 'deschem' i can confirm is good.

'ben0315' is also good.

Just buy some stuff.

We did, and those sellers turned out OK (more than just OK in a couple of purchases).

arkoma - 29-5-2016 at 15:04

way more than OK. Good stuff, good value, quick warranty service.

j_sum1 - 30-5-2016 at 01:27

nanshin is reaceare.
the same paypal account is used for both.
there might be some difference in quality: it is possible that nanshin is seconds stock. I have purchased lots fom reacware and can highly recommend.
I have never had any issues with deschem either.

I got a Graham condenser from cskwin for less than £10 a few months ago. I've yet to see how well it works but it was very well packaged and arrived in one piece.

I got it before I knew how pointless graham condensers are, but at least I got to see what kind of quality their stuff is before I buy a load more.

Duster - 31-5-2016 at 03:34

I don't post a lot but wanted to add that eagle lab glass is a great company. I actually ordered a custom condenser from them (a 1000mm graham) and it was under $200 (I can post the emails and pics of it if you'd like). Not as cheap as an eBay seller no doubt but for US made with very personal service, I can't say enough good things. This is on top of the fact they have no problem dealing with hobbyists.

BILLBUILDS - 4-6-2016 at 21:44

i can personally confirm that nanshin sales has an excellent service and the glassware i have purchaced from his i have had no problems with. the chinese are cheap but they deliver and and problems are always sorted

Cuban_Pete - 18-6-2017 at 21:41

This thread is a bit old but since it is specifically about Nanshin glass i will relate what just happened to me. I ordered $300+ worth of glassware (after getting a great deal on them for a $25 PE Funnel) I am not sure about the rest of the stuff (the still heads, etc.) But every flask they sent me arrived not only used but dirty. (There is what looks like hard water stains in the bottom of each flask, and there are coloured flakes of what i assume are metal oxides in the 500ml 3-Neck.) The seller had been every attentive. When i explained to him that the flasks were used and that i was producing essentual oils and that i absolutely couldn't use second hand labware for this, he insisted that it was impossible for the stuff to be used since they are a glassblowing factory not a laboratory.

When the final parcel arrived Monday, i emailed him again to inform him that the thermometer was missing and one of the Erlenmeyer flasks arrived broken. The white writing on the Erlenmeyers is badly smeared as if these were also used and then soaked in a strong solvent. I haven't heard from them since. (The ebay term is "The Seller went silent" ;-)

The custom glassware i ordered was new and in nothing like the condition of the dirty flasks i received. Has anyone else bought stuff from Nanshin and have it arrive dirty or with circular hard water stains? (It is pretty obvious that at the very least someone tried to clean the flask with tap water and then let the flasks dry "neck up". The custom glassware (a 3L biomass flask) was brand new but not very high quality. (A bubble in the glass, rivulets of glass running up and down the joints.)

I think what is happening is that Nanshing getting broken glassware, repairing it and then selling it as "new" on ebay without bothering to clean it!

I am curious because people here say Nanshin has a better rep than Deschem on Ebay?

It's not uncommon for mail order glassware to arrive dirty from various sources.... Nanshin is generally awesome. I highly doubt they are selling you used glassware.

Cuban_Pete - 18-6-2017 at 21:51

Thank you JJay,

I honestly appreciate your reassurance, but how can dirty glassware not be used? Why would they have let water dry and stain a new flask?

JJay - 18-6-2017 at 22:06

I don't know... it could be that the glassware sat in storage and got dusty.

alking - 19-6-2017 at 09:04

That's my guess. I've used nashin before without issue, but I have received some flasks that were wet or had some water stains, not a lot, but occasionally. I've also received some that obviously had dust in them and I had to wash them out. I strongly suspect they simply rinsed them out, I can't imagine they're actually used or broken and repaired. Think about how cheap it is for them to make this stuff, the glass is practically free, repairing a broken flask or cleaning and repairing one might possibly cost them more than simply making a new one.

PirateDocBrown - 19-6-2017 at 10:34

I have had 2 orders from Nanshin, one was a complete fractional distillation set, and the other a large fritted funnel, a thermometer well, and large 2 neck flask. Both orders arrived clean, unflawed, unbroken, and apparently new. I'm entirely satisfied.

I also got a flask from Laboy, with similar satisfaction.

Praxichys - 19-6-2017 at 11:09

The water spots you are seeing is residue from the flush coolant used when they grind the joint tapers with a diamond tool.

Cuban_Pete - 26-6-2017 at 11:22

Hi,

Thanks for all your replies. Praxichys convinced me that these water marks are normal. However the red and black flakes inside and on the 500ml three neck still leave me a bit leery.

In summary so far, I wrote a letter to Nanshin on ebay saying that i thought the flasks may have been used. I also wrote that the thermometer included in the Organic Chem kit was not in the package and that one of the Erlenmeyers was broken. I haven't heard from Nanshin in about a week. I recently wrote them a letter saying that others (praxichys) have convinced me the water stains are normal but we still need to resolve the issue of the broken erlenmeyer and missing thermometer. I still haven't heard from him. I want to make clear that the shipping damage was NOT Nanshins fault. The postal agent, upon inspecting the unopened but severely damaged box also said that box was properly packed and shipped. She opined that the box had been subject to forces greater than would be expected had it been dropped from a 6' height. I communicated this to nanshin and made it clear this was NOT their fault (and sent him pictures of the damage.)

However i have not heard back from Nanshin. (He simply went silent.) In all fairness i did read of a similiar experience with Deschem on ebay. It seems if there is any problem with these sellers, the seller will simply "go silent". Just a heads up. Thank you all again for your replies.

JJay - 26-6-2017 at 11:47

Since you made it clear that it's not Nanshin's fault that your glass is broken, he probably thinks you don't want a refund. Nanshin is an honorable seller; if your glass is broken, ask for a refund.


Cuban_Pete - 26-6-2017 at 15:59

Thank you for your reply JJay,

I am a bit confused, i made clear the BROKEN erlenmeyer was not his fault. (Although Nanshin guarantees against shipping damage). I don't see how he could have interpreted the fact that they forgot to pack a thermometer as not being his fault. As far as his not thinking i wanted a refund, this is the ending of the letter i wrote Nanshin:

"...but perhaps on my next order with you, you could agree to throw in a thermometer (it simply didn't get packed) and an erlenmeyer. Please find attached photos of the damage."

SOME reply might have been in order. I am more than willing to admit there is a HUGE language barrier in our midst. Nanshin also offered me a 15% discount if i avoided Ebay and ordered from him directly. I would advise people in this group not to do so with unknown sellers as you lose any recourse that way. Again just a heads up.




JJay - 26-6-2017 at 17:11

You singled out Nanshin specifically with the aim of undermining their good reputation. You are an unknown member and the experience you claim to have had doesn't match the experiences that I personally and others have had. Just pointing out the facts.

Cuban_Pete - 26-6-2017 at 18:01

Dear JJay,

I did not "single out" Nanshin. Nanshin is the first and only seller i have used on ebay Deschem also has an excellent reputation and also has a similar experience described regarding them on ebay. (As i mentioned in a previous post. So in fact, your accusation that i am singling out Nanshin was proven false BEFORE you made it.) Please allow me to quote myself:

"However i have not heard back from Nanshin. (He simply went silent.) In all fairness i did read of a similiar experience with Deschem on ebay. It seems if there is any problem with these sellers, the seller will simply "go silent". Just a heads up. Thank you all again for your replies."

You also claimed that i never asked them for a refund, a false statement that you couldn't possibly have any idea as to whether or not it was true. (Unless you 've been monitering my ebay emails?) I think the fact that you are resorting to falsehoods and personal attacks ("you are an unknown member blah blah") undermines their reputation more than i am by simply stating facts.

thanks
peter

I see little reason to argue about this, and your anger is not really necessary. People are much better off buying from Nanshin than, for example, Yee Chen. I personally prefer buying from Nanshin over Deschem.




Cuban_Pete - 26-6-2017 at 21:14

Huh JJ?

Excuse me, but if you see no reason to argue, why are you slamming me with personal attacks? You were caught outright lying TWICE and now you are accusing me of being angry? Do you think every time someone catches you lying that means they are angry?

That is even more absurd than your statement that i had not asked Nanshin for recompense. You had no way of knowing whether or not i had asked Nanshin for recompense yet you blatantly posted otherwise. (In fact i had) You have no way of knowing my emotional state, in fact i am laughing at your childish trolling. You accused me of singling out Nanshin, i quoted myself where i stated that the very same thing happened with Deschem.

If your childish trolling was an attempt to make me angry, you failed. If the purpose of your childish behaviour was to make me leave this forum in disgust, you succeeded.

Oh wait, i see now YOU ARE angry because you were proven a liar and you are trying to reflect it on me! Why don't you just admit you were caught lying and grow up?

Frankly, If this place is so poorly moderated that you can troll here, then my talents are better spent elsewhere. You antics may work on making your parents angry, normal adults merely turn their noses up at you. I am not angry i am disgusted. You need to learn to tell the difference between myself and your mommy! :-)

good bye

JJay - 26-6-2017 at 22:12

I don't even really know what to say - this guy is irrationally paranoid and accusatory, and he lacks manners.

Indeed, you'd better spend your 'talents' elsewhere.
Your 'talent' of getting everyone angry in your first contacts on this forum is not needed here. I will lock your account for posting for one week and hopefully you cooled down again after that.

Old topic, but still strong. My experiences from different vendors, having ordered thousands worth of stuff:

Deschem: my favorite, has wide selection and quality has thus far been good (enough for me), some glassware have imperfections like cast drips and some dried up dirt is not uncommon, but nothing that won't rinse easily off - I wash my stuff anyway before using them for anything critical, and if you need "essential oil pure" whatever that means, you will rinse them with piranha or aqua regia prior to use. Once when I had trouble due to shipping reasons, the response was very swift and professional and I'm most happy customer of theirs.

Nanshin: one fritted filter just slit apart when drying, indicating poor annealing. They went silent when I inquired about the matter. Their vacuum desiccator stopcock also broke off when carefully attaching a vacuum hose, it was brittle to touch. From two experiences their quality might have some room for improvement.

I've also ordered some small stuff from other vendors, generally having no other issue but sometimes extremely long shipping times.

(Europe) Neubert-Glas offers good quality, but their communication and shipping times can have somewhat wider tolerance.

Fery - 26-1-2021 at 23:03

Fyndium - I have very good experience with nanshinglass. 2 orders from him, both above 200 Eur. I ordered 120 mm long capillary melting point tubes and he mistakenly sent me 100 mm - after notifying him he sent me immediately 120 mm. Thermometer adapter had a star crack and he sent me new one. He always apologized and responded very quickly both times.

Yeah ithink the same thing.its just not washed very well and there's no telling whether the factory has its own water recirculation system or what the quality of Chinese tap water is like.my tap water here is full of calcium.
