About Our metal cutting fluid bacteria & ph test kit

This metal cutting fluid test kit is for testing the bacteria, yeasts, moulds (fungi) and pH levels of metal cutting fluids to comply with HSE MW5 ('Managing sumps and bacterial contamination') Control of Substances Hazardous to Health Regulations: (http://www.hse.gov.uk/pubns/guidance/mw5.pdf).

The Metal Cutting fluid test kit includes:

1 x Full colour, 18 page dip-slides.com instruction manual with step by step instructions (including photos) and record sheets.
1 x dip-slides.com pre-calibrated MX2 Dipslide Incubator for MCBTM2 dipslides (1 -2 dipslide capacity)
2 x boxes of Metal Cutting Fluid dipslides - MCBTM2 (bacteria, yeasts and moulds test), 20 dipslides in total.
1 x box of Premium pH Indicator strips (pH 6.5 - 10.0)
1 x Refractometer 0–32% Brix. This is an optional item (as you may already have one of these). A refractometer can be used to test the concentration of industrial / metal cutting fluids. Testing the concentration is important as having a high or low concentration can contribute to adverse health effects, ineffective lubrication, machine breakages and bacterial contamination. Please choose from the dropdown if you wish to include this item.
1 x Temperature Sensor - In accordance with HSE MW5 regulation, you are now required to monitor the temperature of your MWF weekly. Please choose from the dropdown if you wish to include this item.

How to use the metal cutting fluid test kit.

Dip the MCBTM2 dipslide into the metal cutting fluid (MWF).

Dip slide into fluid

Fully submerse the dipslide (so all the agar is covered) into your cutting fluid sample for 10 seconds. After which, remove the slide and allow the fluid to drain off before returning it to the tube.

Place the MCBTM2 dipslide into the incubator.

Place dipslide into the incubator

Place the dipslide into your incubator and inbucate for 24-120 hours (see instruction sheet for exact times).

Compare the dipslide results with the comparison chart.

Review Results

Remove the dip slide from the incubator and compare the results with the comparison chart provided.

Testing the pH of metal cutting fluid can indicate whether levels are corrosive. Low pH levels can be caused by the presence of bacteria. This is why using dipslides and pH strips together gives a fuller indication of the 'health' and quality of your cutting fluid.
Ideally, you do not want your cutting fluid to have a lower pH than approx 8.5 as any fluid that is too acidic will corrode metals. However, you don't want a pH level that is too high as it can pose a risk to health (skin irritation etc).

When you carefully dip the indicator strip into fluid, the strip will change colour in accordance with its pH level. These indicator strips are colour fixed and non-bleeding so results should be clear and accurate.

Each box of pH indicator strips contain 100 strips. A colour indicator chart is also included.

The Metal Cutting Fluid dipslides (MCBTM2) dipslides test the cutting fluid for bacteria and yeasts / moulds. Regular microbiological testing of metal cutting fluids is very important. High levels of bacterial contamination will degrade the quality of the fluid and will become a health risk. Contamination can also cause the pH level to lower to acidic levels.

There are 2 boxes of dipslides in this kit (20 dipslides) . To test your metal cutting fluid using these dipslides, carefully dip the slide within the fluid and immerse fully then replace the slide within its tube. You will then need to incubate the slides and once incubated, compare results with the comparison chart provided to evaluate if contamination is present.

The GNAT incubator will incubate 1 - 2 dipslides. It is ready to use after an initial 15-20 minute stabilisation period. The incubator is pre-set at 30 degrees Celcius.

This kit will provide everything you need to effectively test the microbiology and pH of your metal cutting fluids.

HSE.gov.uk advice	Good control. Bacteria are being maintained at low levels. Regular checks and actions to maintain the fluid quality should continue.		Reasonable control. Review and take action to check the quality of the metalworking fluid and adjust fluid parameters to those recommended by the supplier. If bacterial growth continues despite these adjustments, add biocide at the dose recommended by your supplier.		Poor control. Immediate action should be taken in line with the risk assessment. Normally draining and cleaning should take place

Customer Questions

Q	Is this metal cutting kit for soluble cutting oil and neat cutting oil?
A	The dipslides in this kit will work with all cutting fluids and will show the bacteria + Yeasts and mould colony counts.
Q	What are the acceptable levels and what do I do if it is over?
A	For the UK, HSE recommend 10/2 and under (see "reading the results" above). If your bacteria level is over this, you will need to review control measures and follow manufacturer's guidelines on cleaning your liquid/machinery.
Q	How often do you need to carry out these tests? What is the difference between the BTM2 dip slides and the metal cutting fluid dip slides?
A	The HSE state the following: --- For many systems and sumps, weekly checks (such as dipslides) will be required. The risk assessment may vary this period if the continuing control of bacterial contamination can be demonstrated. Checks (such as dipslides) will normally be required at some intervals to check continuing control. --- As such, we would recommend following the HSE guidelines.
Q	At what temperature is the incubator set at or can you vary incubation temperature? Also what do you recommend as a safe disposal method of the incubated dip slide as they could potentially be a biohazard.
A	Hello, The incubator has a fixed setting at 30 Degrees C by default which is recommended for these dipslides. It can be supplied set to 35 if required but this can not be changed by yourself as the temperature is controlled internally. Used slides should be incinerated, autoclaved or soaked in disinfectant for several hours before disposal. If you have any further questions, please let us know.
Q	Please i need a quotation for 1 metal cutting test kit and an incubator.
A	Hello, All our prices are listed on our website. If you add your desired items to our website basket, it will calculate the exact shipping cost during the checkout. No payment is needed to view the total cost of the order.
Q	Do your slides work when there is a layer of hydraulic oil on top of coolant?
A	Hello, This should not affect the the test but if you have any issues, please let us know.
Q	Hi, Do you offer a dip slid that is specific for legionella in soluble cutting oils?
A	Hello, No, please see our blog post at https://dip-slides.com/blog/dip-slides-for-legionella-testing.html regarding Legionella testing as this explains why we do not offer a dedicated legionella test and which dipslides to use to test water health.
Q	I have bought your metal cutting fluid kit but I am unsure how long to place the slides in the incubator. Under the photo on your website it states 24 - 120 hours. But I'd have thought the longer you leave the slide incubating the worse the growth would be. Can you please advise.
A	For the metal cutting dipslides, the two sides of the slide have different incubation times. The lighter coloured side (nutrient) needs 24-48 hours to incubate for your total count. The darker brown side (malt extract) needs up to 120 hours to incubate. This will then allow the mould / yeasts to grow. You can pull the slide out of the incubator at any point to check the results/make notes of how many colonies (e.g. red spots or moulds) are growing. Please note, it is not the size of the colonies that you count but the amount of them. As such, you may find the mould side has 1 colony grow and simply gets larger over the reminaing incubation time. This would still be a 'Light' level. However, if the slide has approx 8+ colonies of mould (even if small) it would be a 'medium' level. You should also have received a comparison chart inside your kit which should have example images to compare to.
Q	How many tests can be performed per metal cutting kit. What is the recommended testing frequency per unit?
A	The metal cutting test kit includes 20 dipslides. You would need 1 dipslide per test. Regarding test frequency, please see http://www.hse.gov.uk/metalworking/bacterial.htm ("For many systems and sumps, weekly checks (such as dipslides) will be required.")
Q	Can you point me in the direction for a kits for a metal cutting band saw coolant regards
A	For metal cutting coolant testing, we would suggest either our metal cutting kit or our premium metal cutting kit. These can be found at https://dip-slides.com/30-kits
Q	Which metal cutting fluid test kit should I get?
A	There are several factors to look at when choosing your metal cutting fluid kit. We have explained in detail which kit might be suitable for a user's requirements in our blog post here: Which metal cutting fluid test kit is best for me? Hope this helps.
Q	Do the kits come with record sheets?
A	Both of our metal cutting fluid kits include a full step by step user manual showing you how to perform all the tests. There are sheets at the back to record your results. You can also download our free excel record sheet document. You can find more details on this here: https://dip-slides.com/extras/121-excel-compliance-sheet-for-metal-cutting-test-kits.html
Q	Can I buy the refill metal cutting dipslides for this kit?
A	Yes, our MCBTM2 dipslides are available to buy here: https://dip-slides.com/home/31-metal-cutting-fluid-dipslides-box-of-10.html
