Hi,
Do they weigh the tank before and after filling?
Thanks!

No, they don't weigh the cylinders.

Yeap they don't. They do inspect your tank briefly for any signs of wear and tear though.
the pressure gauge does not show whether the tank is full or not. however,it does tell you whether there is liquid CO2 left in the tank. as long as there is liquid CO2 in the tank, the pressure gauge will show ~1000psi (temperature dependent). CO2 pressure will only start to reduce when all liquid co2 is used up.Originally Posted by DeadEnd
weighing is the most accurate way of telling whether the tank is fully filled.

I guess sending to factory is the best option?
@ DeadEnd
Pressure is dependent on temperature. Once liquid CO2 is used up, pressure will start to drop at around 800psi.
Tanks are sold differently either by weight or volume, such as 5lb co2 tank or 2kg FE or 5l co2 tank based on region.
For example,
In the US, it is sold by lbs. A 5lb co2 tank is rated to contain 5lb of co2. Its water capacity is typically higher.
When the tank is sold in litres, it is only filled up to 65%-68% of its water capacity (litres).
Regardless, all tanks are filled up to to 65%-68% of water capacity for safety margin because of pressure. (US is 68%, Aust is 66%)

Bioplast's refills and one-to-one exchanges have lasted about the same time for me. Can't see any significant difference.
my 2kg just ran out during the past week. im quite disappointed because it lasted 7 weeks on a refill from bioplast compared to when i bought the tank fully charged from 328--it lasted 3 months. i use a black ceramic atomiser (higher working pressure than glass diffusers). about 0.7 bps 6 hours a day.
when i was at bioplast the uncle suspended the tank from a hook which i believed was connected to a weighing gauge...so he checks the weight as he fills it. i must be mistaken is bossteck says they dont weigh. honestly i hope i just have a leak that i can fix. because i dont want to have to refill every 1.5 months
When I topped up my 1L tank (not a Bioplast), the co2 only weigh about 200g after weighing it.
I didn't attempt to freeze the tank before topping up.
Just got back from Bioplast. The tank was put in a bucket of water and was hung from a weighing gauge.
I believe he has a compressor running for the Co2 and he had to switch on another equipment on another rack. Not sure what are they.
He constantly adjust the pressure from the main tank and pour chill (?) water over my tank in the bucket.
My tank after the refill definitely weighs more than my previous top up at another lfs. The co2 weighs about 600+g which is about right for a 1L tank.
The moss in his tanks is just amazing.
Where is bioplast new address. Their location at b22 boon keng rd seems to make way for new development

I was at Blk 22 Boon Keng Road.
Are they moving?
